Basic Docker Commands: How to Use Docker?<\/h2>\n
In this section, we will list and discuss the basic commands that you should know to run Docker on your Linux system.<\/p>\n
1. Check Docker Installation<\/h3>\n
Before going into depth about Docker container management, first, it\u2019s important to verify your Docker installation. To view the currently installed docker version, use the `docker version` <\/strong>command that displays detailed information about the installed Docker version, while docker info offers system-wide details, helping in troubleshooting and optimization.<\/p>\n You can search for a specific application image using the `docker search ‘ command.<\/p>\n For example, we want to search for the \u2018mariadb\u2019 image. The above command will be modified in this way:<\/p>\n Docker images serve as the blueprints for containers. To download a Docker image, use the `docker pull`<\/strong> command to download an image from a registry. The syntax for using this command is given below:<\/p>\n For example, to download a test \u2018hello world\u2019 Docker image, you will use the below command:<\/p>\n Building custom images is a common practice in Docker. The docker build command allows you to create an image from a Docker file.<\/p>\n To view all locally available images, use the docker images command.<\/p>\n Containers are instances of images. docker ps lists running containers, while docker ps -a includes stopped ones.<\/p>\n The docker run command creates and starts a container from a specified image.<\/p>\n For example, we want to run the downloaded \u2018hello-world\u2019 Docker image. To run this image, the above command will be used in the following way:<\/p>\n To list all docker container log or running state, use the below command:<\/p>\n Execute commands within a running container using the docker exec command.<\/p>\n You can stop and remove containers. To stop a running container use `docker stop` and remove it with the `docker rm` command.<\/p>\n Unused images can consume storage. Remove them using the docker rmi command.<\/p>\n For example, to remove the \u2018hello-world\u2019 image, use the below command:<\/p>\n You can list all networks and volumes using `docker network ls` and `docker volume ls` commands respectively.<\/p>\n In this tutorial, we have learned the basic docker commands that are necessary to manage Docker containers and images. These commands not only run the docker image but, also you can easily manage your containerized environment using the above basic Docker commands. I hope the above command will give you the complete understanding about Docker Fundamentals. To learn more about Docker, you can visit its official Docs<\/a>.<\/p>\n\n $ docker version<\/pre>\n
