The 20 essential Docker commands you should know in 2023 (2023)

Introduction

Are you new to Docker and wondering how to manage Docker containers efficiently? Don't worry, docker commands can help you with that! Docker is a popular platform that allows developers to package their applications, dependencies, and configurations in containers that run seamlessly in different environments.

With Docker commands, you can easily create, run, stop, delete, and manage Docker containers. These commands help you automate and simplify the process of developing and managing your applications in a containerized environment.

Let's take a look at some of the most commonly used Docker commands that can help you manage Docker containers efficiently.

1. docker execution– This command is used to start a new Docker container from an image.
2. dockworker p.s.- This command is used to list all running Docker containers.
3. docker stops– This command is used to stop a running container.
4. dockworker rm– This command is used to remove a Docker container.
5. pier images- This command is used to display all Docker images currently available on your system.
6. dock worker pulls– This command is used to download a Docker image from a registry.
7. port officer– This command is used to run a command in a running container.
8. docker build- This command is used to manage multi-container Docker applications.

These commands make it easy to manage Docker containers, images, and applications. Whether you're a newbie or an experienced Docker user, knowing these commands can help you improve your Docker skills.

What is Docker?

Docker is a free and open platform that provides an immersive experience for developers working on various aspects of software development. It is a containerization platform that allows developers to package code into multiple deployable units called containers. Docker Engine is the software that oversees container hosting. A subset of the Moby project, Docker helps developers build, run, and deploy containers on the server and in the cloud. The container includes a builder, engine, and orchestrator to provide a seamless application that runs in any environment.

Developers working on individual projects prefer Docker as it provides a lightweight testing environment. It comes with free and premium levels. Docker was first released in 2013 and is written in Go.

Top 20 Docker Commands

We've rounded up 20 docker commands to help you seamlessly navigate the docker engine and get the most of your work done. Let us begin.

• dockable version
• Search docker
• Docker tira
• docker-execute
• Dokwerker p.d.
• docker stops
• Restart docker
• kill docker
• docker executive
• Docker login
• Docker compromise
• Docker push
• Red acoplable
• dockable history
• rmi docker
• ps-a docker
• dockable copy
• docker records
• docker volume
• Log out of docker

1. dockable version

Usually we start by finding the installed version of docker we are working on. This is how to find it:

greatlearning@greatlearning:/home/greatlearning$ docker --versionDocker version 18.09.6, build 481bc77

2. Search docker

The "docker search" command searches for specific images through the Docker hub. This command returns the specific information such as image name, description, automatic official stars, etc. Here's how to use it:

Docker consulta MySQL

You can use the Docker Hub website to search through the GUI-based option.

3. Docker tira

As the name suggests, this command pulls a specific image from Docker Hub. All you have to do is use the 'docker pull' command together with the image name. Here is an example of taking an image without using the tag.

docker pull --platform Linux/x86_64 MySQL Este es un ejemplo que muestra cómo extraer una imagen del servidor Apache HTTP del repositorio de Docker usando la etiqueta -Use default tag: latest: Pull from library/httpdf5d23c7fed46: Pull complete 7fcaa52f : Pull complete622a9dd8cfed : Pull CompleteDigest: sha256:8bd76c050761610773b484e411612a31f299dbf7273763103edbda82acd73642Estado: http://downloadedleargrelearning@ εκμήματηση$

Tags are used to identify images in the Docker hub. If you don't specify a tag, the ':latest' tag will be used by default.

We can use the '-all-tags' command to get all images from the multi-image repository.

4. docker-execute

This command is used to create a container from an image. Here's how to do it -

ventana acoplable ejecutar --env MYSQL_ROOT_PASSWORD=my-secret-pw --deach mysql

The “–unlink” option runs the container and the “–env” option is used to set the mandatory variable. If you don't use the '–name' option, docker will randomly assign a name to the container.

5. Dokwerker p.d.

This command is used to list all the containers that are running in the background. Here's how to do it -

docker ps --all

6. docker stops

The 'docker stop' command stops a container using the container name or its ID. Here's how to do it -

docker stop f8c52bedeecc

7. Restart docker

This command is used to restart the stopped container. It is recommended to use it after rebooting the system. Here's how to do it -

greatlearning@greatlearning:/home/greatlearning$docker herstart f8c52bedeecc

8. kill docker

This command is used to stop the container immediately by stopping its execution. While the 'docker stop' command helps to shut down the container in time, the 'docker kill' command stops it immediately. Here it is to use it -

greatlearning@greatlearning:/home/greatlearning$docker kill 09ca6feb6efcUse the following command to check if the container is stopped or killed -greatlearning@greatlearning:/home/greatlearning$ docker psCONTAINER IMAGE CREATED NAME STATE

9. docker executive

This command is used to access the running container. Here's how to use it:

docker exec -it test_db bashmysql -uroot -pmy-secret-pwTOON DATBASES;

You must specify the name or ID of the container, in this case "test_db". The '-i' and '-t' options are used to access interactive mode.

10. Docker login

This command will help you connect to your docker hub. When attempting to connect, you will be prompted for your docker hub credentials.

greatlearning@greatlearning:/home/greatlearning$ docker login Log in with your Docker ID to push and pull images from Docker Hub. If you don't have a Docker ID, go to https://hub.docker.com to create one. Username: greatlearning Password: Set up a credential wizard to remove this warning. See: https://docs.docker.com/engine/reference/commandline/login/#credentials-storeLogin successful

1. Docker compromise

This command is used to create or save an image of the edited container on the local system.

Here's how to use it:

greatlearning@greatlearning:/home/greatlearning$docker commit 09ca6feb6efc greatlearning/httpd_imagesha256:d1933506f4c1686ab1a1ec601b1a03a17b41decbc21d8bbbat30909 here is username90bcd909 and 'httpd_image ' is the name of the edited owner image.

2. Docker push

This command helps to push or upload a docker image to the docker repository or hub. Here's how to use it:

greatlearning@greatlearning:/home/greatlearning$ docker push greatlearning/httpd_imagePush apunta al repositorio [docker.io/greatlearning/httpd_image]734d9104a6a2: Pushed635721fc6973 httpdbea from library6973: Linked from library74bd64/8. f9c3b51: Montado desde la biblioteca/http d9d 542ac296cc: Montado desde la biblioteca/httpdd8a33133e477: Montado desde la biblioteca/httpdlatest: resumen: sha256:3904662761df9d76ef04ddfa5cfab764b85e3eedaf1026175c size:24b175c

3. Red acoplable

The 'docker-network' command is used to get the details of the list of networks in the cluster. Here's how to use it:

greatlearning@greatlearning:/home/greatlearning$ network docker lsNETWORK NAME DRIVER NAME SCOPE85083e755f04 bridge bridge localf51d1f2379e0 host host local5e5d9a154c00 none null localIn addition to this, you can also create a network -Dickers to manage the following connection commands - to disconnect a container from a networkCreate - to create networks Ls - to list all networks Inspect - to view detailed information about one or more networks sprune - to remove all unused networks srm - to remove one or more networks Docker History This command is used to check the history of a docker image.
