    Top 55+ Basic Docker Commands You Must Learn in 2024

    DevOps is a natural evolution of software development. DevOps is not just a tool, a framework, or just automation. It is a combination of all these. DevOps aimed to align the Dev and Ops team with shared goals. A developer builds an application and sends it to the tester. But, the environments of development and testing systems are different; thus, the code does not work. There are two solutions to this: Docker and Virtual Machines.

    Dockers have been used widely in many DevOps toolchains. Dockers platform provides numerous features that make it popular among developers. Some features include application isolation, portability, security management, Ease of software delivery, scalability, etc. Let's discuss the basic docker commands in more detail, along with examples! You can refer to the best Docker courses for training related to docker and docker commands. 

    What is Docker?

    Docker architecture

    Docker is a platform that enables the creation, deployment, and running of applications with the help of containers. A container is a unit of software that packages the code and all its dependencies together so that the application becomes runnable irrespective of the environment. 

    The container isolates the application and its dependencies into a self-contained unit that can run anywhere. Container removes the need for physical hardware, allowing for more efficient use of computing resources. Containers provide operating-system-level virtualization. Additionally, using Docker commands, developers can easily manage these containers, enhancing their productivity and workflow efficiency.

    Let's understand a few of the above commands along with their usage in detail. The following are the most used docker basic commands for beginners and experienced docker professionals. 

    Here is the list of 50+ basic docker commands:

    Top 15 Basic Docker Commands

    1. docker –version

    This command is used to get the current version of the docker 


    docker - -version [OPTIONS] 

    By default, this will render all version information in an easy-to-read layout. 

    2. docker pull

    Pull an image or a repository from a registry 


    docker pull [OPTIONS] NAME[: TAG|@DIGEST] 

    To download an image or set of images (i.e. A Repository) , Once can use docker pull command 


    $ docker pull dockerimage 

    3. docker run

    This command is used to create a container from an image 


    docker run [OPTIONS] IMAGE [COMMAND] [ARG...]

    The docker run command creates a writeable container layer over the specified image and then starts it using the specified command.

    The docker run command can be used with many variations, One can refer to the following documentation docker run. 

    4. docker ps

    This command is used to list all the containers 


    docker ps [OPTIONS]

    The above command can be used with other options like - all or –a 

    docker ps -all: Lists all containers 


    $ docker ps 
    $ docker ps -a 

    5. docker exec

    This command is used to run a command in a running container 


    docker exec [OPTIONS] CONTAINER COMMAND [ARG...] 

    Docker exec command runs a new command in a running container.

    Refer to the following article for more detail regarding the usage of the docker exec command docker exec

    6. docker stop

    This command is used to stop one or more running containers. 


    docker stop [OPTIONS] CONTAINER [CONTAINER...] 

    The main process inside the container will receive SIGTERM, and after a grace period, SIGKILL. The first signal can be changed with the STOPSIGNAL instruction in the container’s Dockerfile, or the --stop-signal option to docker run. 


    $ docker stop my_container 

    7. docker restart

    This command is used to restart one or more containers. 

    Syntax: docker restart [OPTIONS] CONTAINER [CONTAINER...] 


    $ docker restart my_container 

    8. docker kill

    This command is used to kill one or more containers. 

    Syntax: docker kill [OPTIONS] CONTAINER [CONTAINER...] 


    $ docker kill my_container 

    9. docker commit

    This command is used to create a new image from the container image. 

    Syntax: docker commit [OPTIONS] CONTAINER [REPOSITORY[:TAG]] 

    Docker commit command allows users to take an existing running container and save its current state as an image 

    There are certain steps to be followed before running the command

    • First , Pull the image from docker hub 
    • Deploy the container using the image id from first step 
    • Modify the container (Any changes ,if needed) 
    • Commit the changes 


    $ docker commit c3f279d17e0a dev/testimage:version3. 

    10. docker push

    This docker command is used to push an image or repository to a registry. 

    Syntax: docker push [OPTIONS] NAME[: TAG] 

    Use docker image push to share your images to the Docker Hub registry or to a self-hosted one. 


    $ docker image push registry-host:5000/myadmin/rhel-httpd:lates 

    Apart from the above commands, we have other commands for which the detailing can be found in the following link Docker reference

    11. docker rm 

    This command is used to remove one or more docker containers. We can use options such as -f i.e. force removal of running container which internally uses SIGKILL. Or -v  which removes any anonymous volumes associated with the container. 

    Syntax: docker rm [OPTIONS] CONTAINER [CONTAINER...] 


    docker rm container1 

    Removing multiple containers: 

    docker rm container1 container2 container3 

    Removing with -v and -f options: 

    docker rm -v container1 
    docker rm -f  running_container  

    12. docker rmi

    This command is used to remove one or more docker images from the system. We can use some common options such as - f for force removal of an image or --no-prune for not deleting untagged parent images. 


    docker rmi [OPTIONS] IMAGE  
    • Remove a single image: 

    docker rmi my_image:tag 
    • Remove multiple images: 

    docker rmi image1:tag image2:tag image3:tag 
    • Force remove an image: 

    docker rmi -f my_image:tag 
    • Removing image without deleting untagged images: 

    docker rmi --no-prune my_image:tag 

    13. docker push 

    This command is used to upload the docker image to a Docker registry such as  Docker Hub or a private registry. 

    Syntax: docker push [OPTIONS] NAME[:TAG] 


    Command: docker push myusername/myrepository:latest 

     14. docker login 

    This command is used to log in to the Docker registry such as Docker Hub, a private registry, or any other third-party registry. We can use some common options such as -u for the username of the registry, -p for the password of the registry. 

    Syntax: docker login [OPTIONS] [SERVER] 


    • Login to Docker Hub: docker login 

    Command: docker login 
    • Login with username and password: 

    Command: docker login -u myusername -p mypassword 

    Note: In case we need to log in to other Docker registries: 

    Command: docker login myregistry.com 

    15. docker start

    This command is used to start one or more containers. We can use common options such as -a to attach stderr /stdout and forward signal. Also -i  option can be used as an interactive mode where the container STDIN can be attached. 

    Syntax: docker start [OPTIONS] CONTAINER [CONTAINER...] 


    1. Starting Single Container:  

    Command: docker start  container1

    Docker Use Cases

    Let's understand a few of the docker use cases: 

    Use case 1: Developers write their code locally and can share it using docker containers. 

    Use case 2: Fixing the bugs and deploying them into the respective environments is as simple as pushing the image to the respective environment. 

    Use case 3: Using docker one can push their application to the test environment and execute automated and manual tests 

    Use case 4: One can make their deployment responsive and scalable by using docker since docker can handle dynamic workloads feasibility. 

    Let us take an example of an application, 

    When a company wants to develop a web application, it needs an environment where they have a Tomcat server installed. Once the tester set up a tomcat environment and test the application, it is deployed into a production environment. Once again the tomcat has to be setup in a production environment to host the java web application There are some issues with this approach: 

    • Loss of time and effort. 
    • Developer and tester might use a different tomcat versions. 

    Now, let's see how the Docker container can be used to prevent this loss.

    In order to overcome the issues, docker will be used by a developer to create a docker image using a base image which is already existing in Docker hub. Docker hub has some base images available for free. Now this image can be used by developer, tester and the system admin to deploy a tomcat environment. In this way, Docker container solves the problem. 

    Docker Architecture

    Docker architecture generally consists of a Docker Engine which is a client-server application with three major components: 

    1. Generally, docker follows a client-server architecture 
    2. The client communicates with the daemon, which generally takes up the task of building,running, and shipping the docker containers. 
    3. The client and daemon communicate using REST API calls. These calls act as an interface between the client and daemon 
    4. A command-line interface, Docker CLI runs docker commands. Some basic docker commands with examples are listed in the next section. 
    5. Registry stores the docker images 


    DevOps (development + operations) is an evolution born between developers and system administrators. One of the main tasks of DevOps is the automation and centralization of software development and deployment. One of the most popular tools that helps solve this task is Docker. To get a better understanding of Docker commands and more, enroll in Docker Kubernetes training

    Three main features of Docker products are the most distinguishing: 

    • Quick deployment in a variety of environments 
    • Greatly facilitated testing 
    • Possibility of using Docker as a development environment.

    Learning the top Docker commands is essential for any DevOps professional looking to streamline container management and deployment processes. As you continue to explore and learn more about Docker, keeping these commands at your fingertips will prove invaluable in your journey toward DevOps operational excellence.

    Frequently Asked Questions (FAQs)
