Study Notes
Docker Command Purposes
- The
docker commitcommand is used to create a new image from changes made to a container. - The
docker rmcommand is used to remove one or more containers. - The
docker execcommand is used to run a command in a running container. - The
docker tagcommand is used to assign a name to an image, allowing it to be referred to by a more human-readable name. - The
docker inspectcommand is used to return low-level information about a container or image.
Docker Run Command Options
- When running the
docker runcommand with the--rmoption, the container is automatically removed when it exits.
Docker Attach and Exec
-
docker attachanddocker execare used to access a running container, but they differ in their behavior:-
docker attachattaches to a running container and allows you to see its output, but it does not allow you to interact with the container. -
docker execallows you to run a command in a running container and interact with it.
-
Docker Pause and Cp
- The
docker pausecommand is used to pause all processes in one or more containers, allowing for temporary suspension of the container. - The
docker cpcommand is used to copy files or folders from a container to the host machine or vice versa.
Docker Commands
- Docker commit command creates a new image from a container's changes.
- Docker rm command removes one or more containers.
- Docker exec command runs a command in a running container.
- Docker tag command creates a new reference to an image.
- Docker inspect command displays low-level information on Docker objects.
Docker Run Options
- Docker run command with the --rm option automatically removes the container when it exits.
Docker Interactions
- Docker attach command attaches to a running container, while docker exec command runs a command in a running container.
- Docker pause command pauses all processes in one or more containers.
Docker File Management
- Docker cp command copies files or folders between a container and the local file system.
Docker Image Management
- Docker commit command creates a new image from a container's changes.
Docker Volume Management
- Docker volume command manages Docker volumes, which allow data to be shared between containers.
Docker Container Management
- Docker ps command lists all the running containers.
- Docker logs command allows viewing live logs from a container.
- Docker system prune command removes unused data, such as stopped containers and dangling images.
