- .dockerignore
- FROM Sets the Base Image for subsequent instructions.
- MAINTAINER (deprecated - use LABEL instead) Set the Author field of the generated images.
- RUN execute any commands in a new layer on top of the current image and commit the results.
- CMD provide defaults for an executing container.
- EXPOSE informs Docker that the container listens on the specified network ports at runtime. NOTE: does not actually make ports accessible.
- ENV sets environment variable.
- ADD copies new files, directories or remote file to container. Invalidates caches. Avoid
ADDand useCOPYinstead. - COPY copies new files or directories to container. Note that this only copies as root, so you have to chown manually regardless of your USER / WORKDIR setting. See moby/moby#30110
- ENTRYPOINT configures a container that will run as an executable.
- VOLUME creates a mount point for externally mounted volumes or other containers.
- USER sets the user name for following RUN / CMD / ENTRYPOINT commands.
- WORKDIR sets the working directory.
- ARG defines a build-time variable.
- ONBUILD adds a trigger instruction when the image is used as the base for another build.
- STOPSIGNAL sets the system call signal that will be sent to the container to exit.
- LABEL apply key/value metadata to your images, containers, or daemons.
Docker volumes are free-floating filesystems. They don't have to be connected to a particular container. You should use volumes mounted from data-only containers for portability.
