Docker Cheat Sheet All commands below are called as options to the base docker command. for more information on a particular command. To enter a running container, attach a new shell process to a running container called foo, use: docker exec -it foo /bin/bash . Images are just. Reference - Best Practices. Creates a mount point with the specified name and marks it as holding externally mounted volumes from native host or other containers. FROM can appear multiple times within a single Dockerfile in order to create multiple images. The tag or digest values are optional. If you omit either of them, the builder assumes a latest by default. The builder returns an error if it cannot match the tag value. Normal shell processing does not occur when using the exec form. There can only be one CMD instruction in a Dockerfile. If the user specifies arguments to docker run then they will override the default specified in CMD. To include spaces within a LABEL value, use quotes and backslashes as you would in command-line parsing. The environment variables set using ENV will persist when a container is run from the resulting image. Match rules. Prepend exec to get around this drawback. It can be used multiple times in the one Dockerfile. Multiple variables may be defined by specifying ARG multiple times. It is not recommended to use build-time variables for passing secrets like github keys, user credentials, etc. Build-time variable values are visible to any user of the image with the docker history command. The trigger will be executed in the context of the downstream build, as if it had been inserted immediately after the FROM instruction in the downstream Dockerfile. Any build instruction can be registered as a trigger. Triggers are inherited by the "child" build only. In other words, they are not inherited by "grand-children" builds. After a certain number of consecutive failures, it becomes unhealthy. If a single run of the check takes longer than timeout seconds then the check is considered to have failed. It takes retries consecutive failures of the health check for the container to be considered unhealthy. The command's exit status indicates the health status of the container. Allows an alternate shell be used such as zsh , csh , tcsh , powershell , and others.
