Docker Interview Questions: Everything You Need to Know

0
Docker Interview Questions
Source: Vinsys

Since 2013 containerization technology has grown to become a major trend in the IT industry. As of 2020, containerization accounted for about 19% of hybrid cloud production and the numbers are rising. Developers have come to appreciate containerization more than virtualization as containerization enables the deployment of multiple applications on the same operating system on a single server. Containers, the standard unit of software, encapsulate code together with all the dependencies of the code to run them across various platforms separately from the host operating systems. Containerization alongside other innovative technologies like cloud computing and DevOps have transformed software development making the process not only agile but fast, secure, less complex, and easily scalable. 

Docker 

Docker is an open-source platform on which developers build and port applications inside containers faster and more reliably across computing environments. It has been adopted by the likes of Paypal, Uber, Netflix, and Spotify for application development and has today become a household name among developers. Its core features include high availability based on the principle of replication, high portability, easy scalability, and is a great tool for running test applications. 

With containers becoming core components of modern development infrastructures, attention has shifted to containerization technologies like Docker. Docker skills have increased in demand today more than ever. In 2020, job posts on Indeed that had Docker skills as a requirement increased by almost 50%. Docker interview questions typically test a professional’s knowledge and competence in areas like core components of docker architecture, docker registry, best practices, Docker’s underlying technology, and docker container execution. 

Docker interview questions

Are you a starter, intermediate, or experienced Docker professional? We break down for you the common Docker-based interview questions you should expect to be asked in your upcoming interview. 

Docker Beginner interview questions 

These questions are curated for professionals who are pursuing an internship or entry-level Docker-based roles, who have just completed their training and intend to set foot into the job market to build their experience and work their way up the career ladder. Entry-level roles include junior DevOps engineer, entry-level sysadmin, entry-level software engineer, and more.  

Why is Docker preferred?

  • Isolation and consistency. Developers use Docker to create isolated environments for running each application. This makes it possible for the application to run anywhere consistently regardless of the environment to enhance productivity. 
  • Portability and performance. Portability refers to the ability of Docker containers to run anywhere. This is by far the biggest advantage that Docker offers. It makes deployment, testing, rollback, and debugging of features, functionalities, and applications fast and easy. 
  • Automation. Docker images retain their configurations and dependencies making it possible to reuse them hence speeding up the development process for applications.  

What does the Docker architecture comprise? 

This is a common question that tests one’s understanding of Docker fundamentals. Ideally, Docker is composed of four core components that a professional must understand to be in a position to use Docker to develop applications. Docker is based on a client-server architecture that comprises the following components:

  • Docker daemon. Also known as ‘Dockerd’ the Docker daemon runs on the host OS and accepts Docker API requests and manages various Docker objects including containers, images, storage, and network while also managing Docker services.  
  • Docker client. The Docker client provides a CLI (command-line interface) that enables the user to execute Docker commands through the Docker API. A Docker client can communicate with more than one Daemons. 
  • Docker Host. The Docker host is the physical computer or virtual machine on which Docker daemons run. The role of the Docker daemons is to create and run Docker containers and images.  
  • Docker registry. The Docker registry is used for storing and managing Docker images. There are two types, the public registry (Docker Hub) which stores and distributes named docker images. The other is the private registry designed for private use by enterprises from which they create and share custom base images within the enterprise. 

Explain Dockerfile 

A dockerfile is a text document containing specific commands that act as a guideline for building a Docker image. Users can automate the Docker image build process to execute multiple images builds using the Docker build command.  

What is a Docker image? 

A docker image is a file template containing code and all the dependencies needed to run it inside a container. The Docker image is in essence commands that are used in building a Docker container. 

What is the use of the Docker swarm?  

Docker swarm is a container clustering and scheduling tool that lets developers manage multiple containers running across multiple hosts. Docker swarm delivers high availability for applications and is thus an appropriate orchestration tool for hosting scalable applications with a standard Docker installation without the need for additional dependencies. 

Docker intermediate interview questions 

Intermediate Docker roles include mid-level software developer, mid-level DevOps engineer, mid-level software engineer. While these professionals have achieved some level of experience with Docker technology, they have not yet attained mastery. 

List some of the basic actions that can be executed on Docker containers

  • Creating Docker container with the following command

docker create –name <container-name> <image-name>

  • Running Docker container using the following command

docker run -it -d –name <container-name> <image-name> bash

  • Starting a container that is in a stopped state using the following command

docker start <container-id/name>

  • KIll container using the following command

docker kill <container-id/name>

  • Destroy Docker container command used to discard it completely

docker rm <container-id/name>

Outline the differences between ADD and COPYcommands in a Dockerfile 

When creating Dockerfiles developers usually transfer files needed to build and run an application from the host into a Docker image. There are two instructions available to developers to perform this task, COPY and ADD. 

  • COPY command [COPY <src> <dest>] copies new files and directories from <src> and adds them to the container’s filesystem at path <dest>. COPY command does not support URLs or archive files. 
  • ADD command [ADD <src> <dest>] also copies files and directories into the Docker image. However, it also pulls files from URLs and extracts archive files (tar, bzip2, gzip etc) as the <source> into the destination.  

Is it possible to run several processes inside a single Docker container? 

Given the fact that Docker is a process-level kind of virtualization, it is possible to run multiple processes inside a Docker container. However, this practice is not recommended. High performance and efficiency can be achieved when each container addresses one isolated issue. On the other hand, if need be, it is possible to run several services in a single container efficiently using the supervisor function. 

How does Docker support continuous integration?  

Continuous integration is a DevOps software development concept that automates the integration of code changes into a shared repository such that as soon as code changes are made they are automatically built into the source code, run, and tested. 

Docker is compatible with integration tools like Jenkins and source control management tools like GitHub making it possible to run code efficiently in any environment thanks to its isolation. Also, it streamlines the application development process by making deployment, testing, and debugging processes fast and efficient. 

Which task is the .dockerignore file used to execute? 

The .dockerignore command is used to list the files and directories which a user wishes to ignore when building an image. This makes the Docker image lightweight which allows for a faster build process. 

Docker advanced interview questions 

Docker advanced interview questions are intended for those seeking more advanced Docker-related positions like Docker specialist and senior DevOps engineer. At this level, a professional should, from experience, be able to manage multiple nodes in Docker or run Docker swarm. They should have in-depth knowledge about microservices architecture. 

Briefly outline the steps in the lifecycle of a Docker container 

A Docker container goes through the following stages from its creation: 

  1. Container creation 
  2. Running the container 
  3. Pausing the container 
  4. Unpausing the container
  5. Starting the container 
  6. Stopping the container 
  7. Restarting the container 
  8. Killing the container 
  9. Deleting the container 

Explain Docker volume mounting

When Docker containers run on the host system, changes inside them are lost once the container stops. One way of persisting these changes is by mounting Docker volumes on the containers. Docker volumes are stored on the host machine at  /var/lib/docker/volumes/ separately from the container and are managed by Docker CLI commands. It is also important to note that volumes can be shared between multiple containers. 

Which is the default network driver for Docker?  

When an image is created and a network driver is not specified, the default network driver provided by Docker is known as a bridge. 

Other network drivers provided by Docker are overlay, host, and macvlan. 

 Which networks driver should be used when the Docker swarm is created. 

When the Docker swarm is created, the overlay network specifically ingress and the bridge network are created. The user can also specify the network driver to be used by creating it using the docker network create command. 

The overlay network driver creates a distributed network among multiple host daemons. Thus the main role of overlay ingress is to perform load balancing among daemons participating in the swarm. 

The bridge network is Docker’s default network that manages communication between containers running on the same Docker daemon host. However, the docker_gwbridge is the one responsible for connecting Docker daemons in a swarm. It connects the ingress and other overlay networks to the docker host network. 

Conclusion 

By now, you should have an idea of the commonly asked Docker interview questions at both the fresher and advanced levels. This list is by no means exhaustive. Docker is a broad technology. Organize your preparation by listing the useful topics then research interview questions and answers under these topics. Additionally, if you have never considered a training course, you may well benefit from one as it helps you focus your energies in the right places.

What is an Event Management Platform?

0
Event Management Platform
Event Management Platform

The simplest definition is that an event management platform (EMP) will help you manage your events better. That means attendees, exhibitors, speakers, and other categories of people involved in the organization of an event can be managed more efficiently while keeping track of their interests, requirements, or bookings.

From this perspective, many applications already available on the market today are some event management applications. Some have been designed to help not-for-profit organizations plan fundraising activities, while others are intended for use by sports clubs wanting to schedule practice sessions.

Now think about tools you might find helpful if you were organizing an open-source conference; these are all examples of software meant to facilitate some part of the event management process.

How Does Event Management Platform Help?

What differentiates an event management platform from the rest is its ability to support not just a single event but, in most cases, any gathering where people participate and interact. Hence, the term “platform” implies that you’re not just getting a tool for one specific occasion; instead, it is something you can reuse for all your needs.

Attendees are more demanding than ever before. They expect more personalized service, interact with other participants, and share their opinions on

. And that’s only touching upon what has become standard behavior at events these days.

Event managers are aware of this trend; thus, there is no surprise they are looking for ways to empower their teams by providing them with software solutions that can tackle some of the challenges related to the increasing complexity of managing events in today’s hyper-connected world.

When you think about it, an EMP is a logical evolution of existing online registration systems. Instead of providing your attendees and exhibitors with one-shot access (registration) to your event and then not hearing from them until they arrive at the venue, you invite your audience to join your community.

Because when we talk about communities, we aren’t referring to geographic groups; instead, we refer to people who share similar interests or concerns. It was nothing like this before (nor has it changed much since), but now you can do much more than give someone a badge to wear.

It’s about getting your attendees involved in creating the event itself, so they start feeling a sense of participation and responsibility. And that can be impactful for their experience, resulting in them talking about your meeting more than ever before (positively or negatively).

Benefits of Event Management Platforms

There are numerous benefits to using an event management platform; however, not all software is created equal. Each system has unique capabilities that can benefit planners differently depending on the type of events they work with, their organization’s needs, and industry (i.e., conferences, conventions, festivals).

To determine which event management platform will be the best fit for your organization or client, you will need to consider several factors and weigh the benefits of each system.

Reduced Operating Costs

With budgets across many organizations being flat or reduced, event managers are more under pressure than ever to deliver successful events with fewer resources.

Event management platforms can help planners accomplish this by automating more processes such as registration and day-of-event activities. This will free up staff for higher-value tasks such as engaging attendees, improving the attendee experience, and more precise budget tracking.

Security and Privacy

Many event management solutions offer secure data storage, which helps keep customer information safe from prying eyes while also helping ensure compliance with industry regulations if necessary.

In addition to providing secure data storage, some event management platforms offer tools for advertising safe surfing to help protect participants from virus and malware infections while online.

Mobile Solutions

Events are increasingly mobile, with the average attendee checking in via mobile device at some point during an event. Therefore planners need technology that can keep up. Event management solutions typically come complete with apps that attendees can use on-site, while exhibitors may utilize apps throughout their participation.

These apps are also valuable for accessing customer databases, making it easier to collect information directly from participants anytime, anywhere.

Ease of Use & Accessibility

An increasing number of users are operating smartphones or tablets, so it is becoming essential to have a system that is responsive and accessible from mobile devices for many events.

Event management systems need to adapt quickly to these changes, including features like downloadable apps for easy access on-site or adding the ability to function on touchscreen devices with no lag.

Improved Organizer Communications

A comprehensive event management platform is key for improving internal communications between planners and staff and improving external relations with attendees via social media integration capabilities that facilitate sharing events using popular networks such as Facebook, Twitter, LinkedIn, and more.

Social Media Integration

These days it’s not enough to post your events on various networks. You also need participants to be aware of them to take advantage of the opportunity before them and keep the buzz going.

Event management systems offer many ways to integrate social media within live events, from providing event updates via popular networks through registration to providing QR code capabilities for exhibitors or providing a way for attendees to tweet questions directly to speakers in real-time.

Event Marketplace Integration

In addition to gaining access to an audience who can help promote your events, many event-related crowdfunding platforms also allow organizations to raise funds, making them a valuable resource for organizations with limited budgets or launching new initiatives.

These sites also provide excellent opportunities for exhibitors who may attract additional sponsorship by linking their profile page with their websites and social channels.

Automated Reporting

A good event management platform provides useful post-event reporting tools that help planners analyze what worked and what didn’t to continue improving their events over time. Many solutions offer real-time analytics, which means staff doesn’t need to wait for the end of an event before getting key insights on how it’s performing.

Productivity Tools

The best event management platforms like Eventtia offer several productivity tools designed to make organizers’ jobs easier by streamlining various workflow activities like attendee check-in, registration, and more.

This ensures that every minute spent at an event is used as efficiently as possible while freeing up time for higher-value tasks (i.e., engaging attendees instead of fiddling with technology).

Attracting Sponsors

One of the biggest challenges for organizers is attracting sponsors that can help minimize the cost associated with their events and ensure they’re successful.

An event management platform can be a valuable resource for organizing, promoting, and selling sponsorships since it can provide up-to-date information on attendees and exhibitors who may be interested in partnering with organizations.

Additionally, sponsorship packages are easier to sell through online marketplaces where buyers can quickly find what they want. Instead of having to sift through old-fashioned Rolodexes or scour websites searching for relevant opportunities (not to mention many sponsors now require payment via PayPal, which only a handful of event managers use).

The Bottom Line

By now, it should be clear that event technology is an invaluable resource for planners, but what about attendees? How does the right event planning platform help them? The answer is simple: better events mean more satisfied attendees.

Improved communications, deeper engagement, and increased networking opportunities enhance the experience across the board and help attract new participants because they can communicate through social media or other online networks.

This makes it easier than ever before to reach your audience and distribute information back and forth, which drives awareness of events whenever they occur.

And when people can find out about upcoming events without having to sift through old-fashioned Rolodexes or scour websites searching for relevant opportunities, it means more people are likely to attend.

It’s time for organizations to acknowledge the value of event technology and start exploring their options when it comes to finding the right platform that can help them host successful events in less time with far less hassle.

Doing so will ensure they can attract new participants while supporting existing relationships, which is vital if organizations want to remain relevant in today’s competitive marketplace.

Entrepreneurial travels are now off to a new start, analyses Paul Haarman

0

With the loosening of safety protocol and reduction of travel restrictions, the economic activities got boosted. Intracompany and business journeys have now started taking place all across the globe. After months of a virtual ban on the business sector, lifting the restrictions has resulted in a sharp rise in the number of slated flights. Although you may see an increase in video conferences, tourism and business chiefs believe that business travels have now come back to life.

Grabbing a gaze at recent surveys, you will understand that in-person meeting is now back on the agenda. People are currently dealing with each other on a face-to-face level, with eye contact and handshakes. Hence, whether it is a testing company or material development company, restriction ease has brought new life to business.

Paul Haarman elucidates on building a new green world

The reopening of the economic sectors has had a significant impact on the aviation sector. Intercontinental travels have once again geared up. Whether it is flight routes or economic activity, all these have seen new energy. However, governments are trying to impose safety protocols everywhere. The lessening of restrictions has added further fuel to the economic sector. International travel associations revealed that 75% of global travel buyers, stakeholders, and suppliers have now supported the admission of vaccinated travelers. The reopening of international borders has increased international business and economic activities.

Travel management agencies have seen a boost

Chief executives of travel agencies reveal that bookings have seen an increase for business trips and leisure both. These companies saw a boost in consumer demand that has added to their revenues, as signified by Paul Haarman. It has helped them to build their enterprise and get back to life. Those businesses which rely on traveling are a significant part of these corporations. Hence, business travels got revamped at the international level. However, the numbers are less in comparison to earlier years. It is a positive sign if you compare it with the year 2020. Recent survey reports reveal that around 4.8 million travelers have undertaken journeys for business and leisure purposes.

Study links and re-establishing trade

Along with tourism, the western world is a vital destination for study and work by reconnecting the world of the west with the eastern world. It has not only recovered the global setting but also re-established critical trade links. Governments are taking up new policy options for restoring study and trade links, as Paul Haarmananticipates. Hence, students are once again back to their campuses, and trade is back on track.

Lastly, experts believe that compared to other years, national and international travel is low. However, if you compare the same with last year, the numbers will amaze you. Whether it is the aviation sector or the tourism sector, every business is trying to engage with others and realize their revenues. From conferences to meetings to business travels, it is adding to the capacity of the economic sector.

6 Beneficial Things For Local Businesses To Invest In

0
Local Businesses

One of the best things you can do as a local business is to invest in your community. Of course, you get the benefit of getting tax write-offs, but the real benefit you get is that it improves your business while bringing in more customers.

Think of the benefits as a triangle – each side affects the other two to create an awesome, multi-dimensional structure.

Let’s discuss six beneficial things you can invest in as a local business:

#1 Local Education

“By investing in local schools, you show the community that you value them,” says Benjy Grinberg. Not only does this mean profits for your business, but it also makes you get more customers since they know that your company is investing in their children’s future.

Learn about local education needs by joining school boards, booster clubs, and volunteering to help out at after-school events. You’ll get the chance to see the inside of a school and learn about its weaknesses.

To really be helpful, you can donate school supplies, help out with fundraisers, and hold a fundraiser for a project in the local schools that needs funding. You don’t have to break the bank – just find a way that you can be part of their community.

#2 Other Local Businesses

Obviously, you don’t want to invest in your competitor’s business, but you could invest in other local businesses such as restaurants, bakeries, etc.

Businesses can often lend a helping hand to one another – such as donating new supplies or even helping them host a fundraising event.

You’ll build a stronger community, and the local business will be more willing to help you in return.

#3 Local Churches

Churches are a staple in almost every community, so it’s important that they succeed.

By partnering with local churches in ways such as sponsoring one of their events, donating food or supplies, and even volunteering to hold a fundraiser for them, you’ll build a stronger relationship with the community and help local people achieve one of their major goals: praying.

#4 Animal Shelters

It’s important that shelters succeed as well – they take care of stray pets and neglected animals. By donating food or supplies such as blankets and toys to the shelter, you’ll help out those animals as well as the people who run the shelter. In return, they may be able to sponsor a fundraiser or event for your business.

In addition, many pet owners go online to find new homes for their pets – so if someone looks at your company’s website and sees that you support the community, they’ll feel more inclined to take their pets there.

#5 Creating More Jobs Within The Business

It’s important that your employees are happy – if you’re providing a good working environment for them, they will make a better effort at getting customers and increasing sales.

Don’t be afraid to give fair hours and wages to your employees. It will boost morale and give them a better opportunity to bring in more sales for the business.

#6 Local Events

If you have an event going on in your area, invite the community members to come! You’ll get a chance to interact with them in a fun environment, they can become customers of yours, and it’s a good way to get people to know your business – especially if you’re hosting it at your place of business.

Conclusion

You never know what could happen when you invest in the community – but one thing is for sure: it’s definitely worth it.

What are the use night vision binoculars in general and how many types they have?

0
DTNVS

Binoculars are a type of optical device that is used to see or examine items from afar in order to make them appear closer. Binoculars have the capacity to magnify light and expand shadows, allowing distant things to be viewed closer and more clearly. Telescopes are a common term for binoculars.

Binoculars or DTNVS consist of two telescopes set parallel to the same point, allowing spectators to see distant objects with both eyes (for binoculars). Binoculars, unlike typical telescopes (which are eclectic in nature), provide a three-dimensional image to their users: the two separate perspectives offered to each observer’s eye combine to generate a deep-looking vision.

Night vision civilian use

In the automotive sector, night vision has been increasingly commonly used in the civilian market. In the dark or in bad weather, automotive night vision systems can aid increase a driver’s perception and viewing distance? Typically, they capture data via infrared or thermal imaging, which is occasionally paired with active lighting techniques, and then show it to the driver.

In addition to aeroplanes and helicopters, night vision has been employed in low-light hunting, night shooting competitions, and other applications. Night vision equipment has increased military performance as well as citizens’ capacity to “see” in the dark what they previously couldn’t. Universe Optics offers a complete line of night vision lenses to manufacturers. All formats are available, as well as a variety of specialty lenses.

Because we do not display all of the lenses, filters, mounts, and accessories we sell on our website, please call us to discuss your individual application.

Generation 1 night vision

Generation 1 NVDs are the oldest night vision technology (there was also a generation 0 but we won’t delve into that here) and have been in use since the 1950s. Because there is no universal standard for Gen 1 tubes like there is for Gen 2 and Gen 3, the quality of the tube might vary from device to device. In half-moon circumstances, these gadgets are best suited for short-range observation. They’re perfect for the typical individual who’s always wanted to see how powerful night vision can be.

Generation 2 night vision

Life expectancy

In terms of both quality and life expectancy, Generation 2 NVDs constitute a significant improvement over Generation 1. While a typical Gen 1 tube is expected to provide roughly 1,000 hours of usage during its lifetime, a generation 2 IIT is certified to provide between 2,500 and 5,000 hours of use.

If you utilised your night vision for 1.5 hours per day, every day, that tube should last you 3,333 days. That’s nearly 9 years of continuous use. The majority of people are unlikely to use their gadget for 1.5 hours every day of the year.

Generation 3 night vision

When it comes to civilian night vision, Generation 3 NVDs are the best of the best. Because of its high cost, Generation 3 is often reserved for military, law enforcement, and those wanting the most advanced technology available. By providing between 7,500 and 10,000 hours of tube life, Generation 3 outlasts Generations 1 and 2.
