Docker CLI — Shell Completion & Plugin Discovery

Upstream patch for the official Docker Command-Line Interface (docker/cli in Go): fixed shell completion routines under Zsh for third-party and native plugins, preventing arithmetic evaluation errors and stabilizing plugin discovery.

The Command Line Experience

The official [Docker CLI](https://github.com/docker/cli) is executed millions of times daily by developers worldwide. When using Docker CLI plugin architectures on modern Unix shells like Zsh, automated completion routines could encounter evaluation errors under specific environment configurations.

[ TIP ]Fixed Zsh shell completion routines to properly handle dynamic plugin binary paths without throwing evaluation exceptions during tab-completion.

Technical Details

  • Language: Go / Bash / Zsh scripting
  • Component: cli/command/completion
  • Resolution: Streamlined plugin list expansion and ensured robust fallback when plugin binaries return non-zero exit codes during inspection.
