Briefly Explain Basic Docker Commands?

Docker is a popular containerization technology that allows you to package and deploy software applications in a lightweight, portable, and scalable way. It provides a range of powerful commands that can be used to manage Docker containers, images, and networks. In this blog post, we will discuss all the essential Docker commands that you need to know.

1. docker run - This command is used to create and run a new container. It takes the form docker run [OPTIONS] IMAGE [COMMAND] [ARG...]. For example, to run an Ubuntu container, you can use the command docker run -it ubuntu.
2. docker build - This command is used to build a Docker image from a Dockerfile. It takes the form docker build [OPTIONS] PATH/URL. For example, to build an image from a Dockerfile in the current directory, you can use the command docker build -t myimage ..
3. docker images - This command is used to list all the Docker images that are present on your system. It takes the form docker images [OPTIONS] [REPOSITORY[:TAG]]. For example, to list all the images that are present on your system, you can use the command docker images.
4. docker ps - This command is used to list all the running Docker containers. It takes the form docker ps [OPTIONS]. For example, to list all the running containers, you can use the command docker ps.
5. docker stop - This command is used to stop a running Docker container. It takes the form docker stop [OPTIONS] CONTAINER [CONTAINER...]. For example, to stop a container with ID abc123, you can use the command docker stop abc123.
6. docker rm - This command is used to remove one or more Docker containers. It takes the form docker rm [OPTIONS] CONTAINER [CONTAINER...]. For example, to remove a container with ID abc123, you can use the command docker rm abc123.
7. docker rmi - This command is used to remove one or more Docker images. It takes the form docker rmi [OPTIONS] IMAGE [IMAGE...]. For example, to remove an image with ID abc123, you can use the command docker rmi abc123.
8. docker exec - This command is used to run a command in a running Docker container. It takes the form docker exec [OPTIONS] CONTAINER COMMAND [ARG...]. For example, to execute a command ls in a running container with ID abc123, you can use the command docker exec -it abc123 ls.
9. docker network - This command is used to manage Docker networks. It takes the form docker network [OPTIONS] COMMAND. For example, to list all the Docker networks that are present on your system, you can use the command docker network ls.
10. docker login - This command is used to log in to a Docker registry. It takes the form docker login [OPTIONS] [SERVER]. For example, to log in to the Docker Hub registry, you can use the command docker login.
11. docker push - This command is used to push a Docker image to a registry. It takes the form docker push [OPTIONS] NAME[:TAG]. For example, to push an image with the name myimage and tag latest, you can use the command docker push myimage:latest.
12. docker pull - This command is used to pull a Docker image from a registry. It takes the form docker pull [OPTIONS] NAME[:TAG]. For example, to pull an image with the name myimage and tag latest, you can use the command docker pull myimage:latest.

13. docker inspect - This command is used to get detailed information about a Docker object, such as a container, image, or network. It takes the form docker inspect [OPTIONS] NAME|ID. For example, to inspect a container with the name mycontainer, you can use the command docker inspect mycontainer.
14. docker logs - This command is used to view the logs of a Docker container. It takes the form docker logs [OPTIONS] CONTAINER. For example, to view the logs of a container with the name mycontainer, you can use the command docker logs mycontainer.
15. docker commit - This command is used to create a new image from a container's changes. It takes the form docker commit [OPTIONS] CONTAINER [REPOSITORY[:TAG]]. For example, to create a new image from a container with the name mycontainer, you can use the command docker commit mycontainer myimage.
16. docker cp - This command is used to copy files between a Docker container and the local file system. It takes the form docker cp [OPTIONS] CONTAINER:SRC_PATH DEST_PATH or docker cp [OPTIONS] SRC_PATH CONTAINER:DEST_PATH. For example, to copy a file from a container with the name mycontainer to the local file system, you can use the command docker cp mycontainer:/path/to/file /local/path.
17. docker volume - This command is used to manage Docker volumes, which are used to store persistent data outside of containers. It takes the form docker volume [OPTIONS] COMMAND. For example, to list all the Docker volumes that are present on your system, you can use the command docker volume ls.
18. docker-compose - This command is used to define and run multi-container Docker applications. It takes the form docker-compose [OPTIONS] [COMMAND] [ARGS]. For example, to start a Docker Compose application, you can use the command docker-compose up.
19. docker swarm - This command is used to manage Docker swarms, which are groups of Docker nodes that work together to run applications. It takes the form docker swarm [OPTIONS] COMMAND. For example, to initialize a new Docker swarm, you can use the command docker swarm init.
20. docker service - This command is used to manage Docker services, which are the building blocks of Docker swarms. It takes the form docker service [OPTIONS] COMMAND [SERVICE]. For example, to list all the services that are present in a Docker swarm, you can use the command docker service ls. docker network

These are just some of the essential Docker commands that you need to know to get started with Docker. With these commands, you can create and manage Docker containers, images, networks, volumes, and services. Docker is a powerful tool that can simplify and streamline your development and deployment workflows, so be sure to take the time to learn these commands and explore what Docker can do for you.
