Docker Interview Questions

Q. What is Docker?
Consider a scenario – You have just joined a new organization as a developer. You will now have to setup the project with the assistance of a fellow developer. He suggests you follow certain steps for setting up the required environment and then start the project deployable like a WAR. You do the same, but keep getting some or other issues regarding environment configuration. May be even your fellow developer has forgot some configuration property he might have set. Well you are stuck in such a situation. This is known as Dependency Hell. Other similar scenario of this dependency hell are – The application is running on my dev machine but not in production. Dont know what issue is. There is also other scenarios like Matrix of Hell. But this is mostly related to DEVOPS people. Docker to the rescue.
Docker is a tool designed to make it easier to create, deploy, and run applications by using containers.

Q. How to deploy Spring Boot WAR to Docker?
Deploying Spring Based WAR Application to Docker

Q. What is the main advantage of containers over a virtual machine?
There are many advantages but the main advantage is that as compared to a virtual machine, containers use less resources and give a saving of around 20%.

Q. Is booting a container slow as compared to a VM?
No, container boots very fast as compared to VM because each VM has its own operating system to boot where as a container uses the host operating system and it just has to initiate container run time.

Q. Who is the original author of Docker?
Solomon Hykes is the principal developer behind Docker.

Q. What is the approximate monthly Docker image download count?
The approximate monthly Docker image download count is around 14 billion per month.

Q. Docker is written in which programming language?
Docker is written in GOLANG.

Q. Name the key components of Docker architecture?
The key components of a Docker system are Docker client, Docker host and Docker registry.

Q. Explain Docker in a single sentence.
Docker is an open source technology agnostic framework to build, transport and run any application.

Q. Explain the Docker container in simple terms.
A Docker container is a unique package of (usually micro services based) an application along with its dependencies that runs under a Docker runtime environment that sits on top of an operating system.

Q. Why is Docker gaining popularity among application developers?
Docker is very important these days because most of the applications are micro services based, with very low coupling and cohesion. Moreover, major software development has gone agile and iterative with quick scaling in and scaling out. Docker makes all these possible.

Q. Which two resources do two Docker containers running on the same system share?
Any two Docker containers running on the same system share OS kernel and binaries or libraries.

Q. Containers existed before Docker came but got major popularity afterwards. Why so?
There were three major problems with containers of pre-Docker time. Firstly, there was no standardized exchange format. Secondly, containers are pretty hard to use for developers since there was no single command to run. Last but not the least, there was no portable mechanism to reuse components such as APIs and tools.

Q. Can you explain the “ship the application” part of Docker?
A modern-day application is structured as a set of independent microservices with well-defined access points. They are converted to images along with their dependencies and shipped. Each image is a set of layers and only changes in layers are shipped (and not the entire layer). This way, we can save on disk usage, reduce network load and minimize memory usage.

Q. Can the same container be passed from a developer to a QA person?
Yes, the developer will write a Docker file for his application. Then he will build the image and push it to a private or public registry. The QA person can pull the same image and run the container.

Q. Assume you are a developer. How will you visualize a container?
I would visualize a container as a collection of the application’s source code, all supporting libraries, required configuration values and relevant data.

Q. Suppose you are a DevOps person. How will you visualize a container?
I would visualize a container as a black box on which I could run operations such as start, stop, kill etc.

Q. What is the easiest way to connect to a VM or a host from a Windows machine?
You could use putty ( to connect a VM/host from a Windows machine. It has a pretty simple and elegant Graphic user Interface.

Q. How does all communication happen internally in Docker?
Internally in Docker, all communication happens over well defined API.

Q. Does the docker user have root-level access?
Yes. docker user by default has root-level access to the host.

Q. Who owns the Docker control socket?
Docker control socket is owned by docker group.

Q. What is the simplest way to print “Hello World” using a docker container?
We can pull and run busybox (it runs a single process printing “hello world”)

$ docker run busybox echo hello world

Q. Suppose you are inside a container say container_1. You exit the container by typing exit on the command prompt. What happens to container_1?
root@container_1:/# exit

Container_1 goes to stop state and all its compute resources get freed. However, it remains on the system’s disk storage.

Q. Explain the typical lifecycle of a docker container?
There can be many combinations of stages in the life cycle of a docker container but here is one of the most common one is given below.

  • Pull or create a docker image
  • Create a container from the image
  • Run the container
  • Stop the container
  • Restart the container
  • Kill the container (if needed)
  • Prune or reclaim the resources used by the container

Q. Can an ARG variable be used by the running container?
No, an ARG variable cannot be used by the running container as it is exclusively reserved for use by dockerfile

Q. What is the best way to assign a database password to a container?
The best way to assign a database password to a container is using ENV variable.

Q. What is the best way to determine container dependency?
It is done by specifying the dependent container in the definition part of depending container. Suppose web service is dependent on auth service. So typical dockerfile would like




restart: always


– auth


Q. How is a container named by default?
A container is named as project_dir_container_base_name_<number>. E.g.



Q. How does Docker view foreground and background containers?
Docker does not distinguish between foreground and background containers. For Docker all containers are the same and run in the same way.

Q. What are the 3 name spaces used for the Docker image?
There are 3 types of namespaces used for Docker image.

Root-like. E.g.

User and organizations. E.g.

Self-Hosted (Private registry)

Q. What are some typical examples of root namespace images?
Official images maintained by Docker Inc. use root namespace. These include small and focused images such as busybox, common operating system distribution such as ubuntu, redhat and ready to plug in components and services such as mongodb, prometheus, redis, stackstorm etc.

Q. How do you identify a self-hosted namespace image?
This type of images contains the hostname or IP address, and the port (optionally), of the registry server.

Q. Why is stateful application more suitable for Docker Container than stateless?
A stateless application is more suitable for Docker container than a stateful application because in a stateless application we can clearly separate application code (in form of image) and its configurable variables. So, we can create a separate container for development, integration and production environment. This promotes reuse and scalability.

Q. What are the different types of virtualization?
Three types of virtualizations are Paravirtualization, emulation and container-based virtualization.

Q. What is the difference between the commands ‘docker run’ and ‘docker create’?
‘docker run’ and ‘docker create’ both is used for container creation but the end result is different. ‘docker create’ creates the container in a ‘stopped’ state and it stores and output container ID for use later. ‘docker run’ creates and simultaneously execute the container.

Q. Why do we have to map ports in Docker to access web services?
We have to map ports in Docker for variety of reasons:

We are out of IPv4 addresses.
Containers cannot have public IPv4 addresses.
They have private addresses.
Services have to be exposed port by port.
Ports have to be mapped to avoid conflicts

Q. What is the difference between virtualization and containerization?
Virtualization is the process of abstracting a physical machine whereas containerization is the process of abstracting an application.

Q. In the following command, Nginx is which port on the host and which port on the container?
$ docker run -d -p 80:80 nginx

nginx is using port 80 on host and port 8000 on container.

Q. Can a container restart by itself?
Yes, a container restart by itself as per the policy set at time of run/create. The policy type can take one of the following values

Off🡪 container won’t be restarted if it stops or fails,
On-failure🡪 container restarts only when a failure that occurred is not due to the user,
Unless-stopped🡪 container restarts only when a user executes the command to stop it,
Always🡪 the container is always restarted irrespective of error or other issues.
Q. How can you list all the stopped containers?
You can see stopped containers, with the –all option with docker ps command. E.g.

$ docker ps –-all

Q. What is Container Networking Model or CNM?
It is formal container networking specification from Docker. It provides container networking with support for multiple network drivers.

Q. What are the two ways to create a new image?
We can create a new image by using commands commit and build. docker commit tells Docker daemon to save all the changes made to a container into a new layer and then create a new image by copying the container. docker build instructs the Docker daemon to create the new image by building each layer iteratively.

Q. What are the two ways to download the docker images?
There are two ways i.e. explicit and implicit. We can download image explicitly using command ‘docker pull’. Implicitly, when we execute ‘docker run’ then Docker daemon searches the image locally and if not found, it downloads the image.

Q. What do STARS signify in the output of the following command?
$ docker search prometheus


jplock/zookeeper Builds a docker image … 27

thefactory/zookeeper-exhibitor Exhibitor-managed ZooKeeper… 2

misakai/zookeeper ZooKeeper is a service … 1

ubuntu/prometheus Prometheus is a … 4

Ans. “Stars” indicate the popularity of the image.

Q. When is it advisable to use image tags?
You should use tags in the following scenarios:

When recording a procedure into a script.
When doing work for the production environment.
When you want to ensure that the same version will be used everywhere.
When you want to ensure repeatability.
Q. Can you compare Chef with Docker?
No, it would not be a fair comparison. Chef is basically a Configuration Management tool that is used by system administrators and DevOps team members to manage the application environments, web-server configuration, databases, and load balancers. On the other hand, Docker is a way to package code into independent and portable units of work known as containers. Containers are later deployed to development, QA and production environments with far greater ease and consistency.

Q. Is it correct to say those self-hosted registries are private registries?
No this statement is not correct. A self –hosted self-hosted registry can be public or private. In fact, a registry in the User namespace on Docker Hub can be either public or private.

Elastic Beanstalk IAM ELK Cloud Watch – Week 4

As companies seek to improve their application development processes by transitioning from waterfall to DevOps, they also recognize that DevOps alone cannot save them. The delay in making capital purchases of hardware and software slows the development process, even if it’s made agile. Developers end up waiting for capital resources to be put in place before the applications can be deployed. Thus, DevOps won’t have much value without the cloud, and the cloud won’t have much value without DevOps. The centralized nature of cloud computing provides DevOps automation with a standard and centralized platform for testing, deployment, and production. During this week, we will set up our project with multiple environments and use Elastic Beanstalk service to replicate the same thing in the AWS Cloud. We will also discuss restricting users to use particular services in AWS using IAM and managing servers with AWS Systems Manager, which is an alternative to Ansible in the cloud.

CI/CD Maven and Gradle Python SonarQube GitLab tool Jenkins – Week 5

Continuous Integration and Continuous Delivery (CI/CD) are critical components of successful DevOps practices. To establish and optimize the CI/CD development model and reap the benefits, companies need to build an effective pipeline that automates their build, integration, and testing processes. At a high level, the pipeline includes compiling, packaging, and running basic tests before a code base merge. After the code is in the main branch of the version control software, additional tests are run to ensure the apps work with real configuration and services. Performance and security tests are also conducted. From there, code is deployed to staging and then to production.

In this week, we will cover the tools that help to establish and optimize the CI/CD pipeline for successful DevOps. We will discuss GIT branching strategies, build tools like Maven and Gradle, functional testing using Selenium and Python code, Code Quality testing using SonarQube, Nexus artifact manager, and GitLab tool. The main focus will be on using Jenkins Pipeline code and Seed Jobs in Jenkins for complete automation to deliver code to production in a smooth manner.

Devops CI/CD Techniques | Simple Storage Server (S3) – Week 6

Continuous Integration and Continuous Delivery (CI/CD) techniques promote collaboration, increase agility, and expedite high-quality product delivery. Cloud technologies have made integrating a CI/CD pipeline easier than ever before. DevOps automation is increasingly becoming cloud-centric, with most public and private cloud computing providers offering systemic support for DevOps, including continuous integration and continuous development tools. This integration significantly reduces the costs associated with on-premises DevOps automation technology and offers centralized governance and control for a sound DevOps process. Many developers find that governance keeps them out of trouble, and it’s easier to control centrally via the cloud than attempting to bring departments under control. In the previous week, we discussed pipeline setups using different tools, and in this week, we will replace them with AWS services. Specifically, we will use S3 buckets as an artifact repository, Code Commit as our GIT repository, CodeBuild instead of Jenkins Builds, Code Deploy instead of Ansible, and Code Pipeline instead of Jenkins Pipelines.

Docker Jenkins Kubernetes – Week 7

Nowadays, it is crucial to release software quickly, which requires an automated CI/CD pipeline to take code from text to binaries and deploy it. Implementing an automated pipeline has been challenging in the past, especially with legacy applications. Docker and Kubernetes solve this problem. Kubernetes has revolutionized the way we deploy and manage containerized applications. Using Helm with Kubernetes simplifies application deployment. Kubernetes is a modern DevOps tool, and the infrastructure side requires a declarative approach. DevOps tools have reduced deployment times from days to hours, and Kubernetes can bring them down to minutes. This week, we will discuss containerization technologies and the basics of Docker. Then, we will delve into Kubernetes in detail and complete all CI/CD setups with Jenkins Kubernetes integrations.

Topics Covered:

  • What is Virtualization?
  • What is Containerization?
  • Virtualization vs Containerization
  • Introduction to Docker
  • Running Docker Containers
  • Making Docker Images with Dockerfile and push them to Docker Registry
  • Launching AWS Elastic Kubernetes Service for practice

Infrastructure as Code (IaC) Terraform – Week 8

Infrastructure as Code (IaC) refers to the management of infrastructure (such as networks, virtual machines, load balancers, and connection topology) using a descriptive model that utilizes the same versioning as the DevOps team’s source code. Similar to how the same source code generates the same binary, an IaC model generates the same environment every time it is applied. IaC is a crucial DevOps practice and is utilized in conjunction with continuous delivery. Tools such as Terraform, AWS CloudFormation, Azure Resource Manager Templates, Google Cloud Deployment Manager Templates, and OpenStack Heat provide an excellent way to define server infrastructure for deploying software. The configuration to provision, modify, and rebuild an environment is captured in a way that is transparent, repeatable, and testable, giving us the confidence to tweak, change, and refactor our infrastructure easily and comfortably. In this week, we will provision all AWS services using Terraform and integrate IAC into our CICD process. We will also deliver the release in blue-green deployments without any outage to the end customer.

Topics Covered:

  • Introduction to IaC
  • Introduction to Terraform
  • Terraform Installation
  • Configuring terraform with AWS
