User Interaction and Usability

The Docker CLI aims to provide a user-friendly experience for interacting with Docker. This includes:

Command Line Options (flags)

The Docker CLI uses flags to provide various options for commands. These flags are defined in the flags folder:

• Example: docker build --tag my-image:latest .
  • --tag: This flag specifies the tag for the built image.
  • .: This indicates the current directory as the context for the build.

Completion Hints (hints)

The hints folder provides completion hints for various commands and options, enhancing the user experience by offering suggestions during command input.

• Example: When typing docker run, the CLI can suggest common options such as -d, -p, and -it.

Reference: tree/main/hints

Command Completion (contrib/completion)

The contrib/completion folder provides shell completion scripts for different shells, enabling users to complete commands and options more efficiently.

• Bash: tree/main/contrib/completion/bash
• Zsh: tree/main/contrib/completion/zsh

These scripts enable users to easily complete command names, options, and arguments.

Help Documentation

The Docker CLI provides comprehensive help documentation for all commands and options.

• Example: docker run --help provides information about the run command and its available options.

The CLI also offers interactive help with the docker help command.

User Feedback

The Docker CLI encourages user feedback to improve the user experience. Users can report issues or suggest enhancements through the Docker GitHub repository.
