DockerCompletion for PowerShell

demo

Completion for

  • Management commands and subcommands
    • container, image, service, ...
  • Legacy commands
    • create, images, ps, ...
  • Command/Option arguments
    • run [image], container inspect [container], ...
    • --filter [key=value], --logDriver [name], ...

All of the completions are customizable.

Requirements

  • PowerShell >= 5.0
  • docker cli >= 1.13 in $env:PATH

Quick Start

# Install from PowerShell Gallery
Install-Module DockerCompletion -Scope CurrentUser
# Import
Import-Module DockerCompletion

Less Quick Start (without Install-Module)

DockerCompletion is a "well-formed" module. You can install and import it in the usual manner as follows.

Install

Download and place the DockerCompletion directory and files in $env:PSModulePath.

You can see the paths listed in $env:PSModulePath as follows:

PS C:\> $env:PSModulePath -split ';'
C:\Users\matt9ucci\Documents\WindowsPowerShell\Modules
C:\Program Files\WindowsPowerShell\Modules
C:\WINDOWS\system32\WindowsPowerShell\v1.0\Modules

If your target path is C:\Users\matt9ucci\Documents\WindowsPowerShell\Modules, execute the following commands:

# Uninstall previous version
Remove-Item $HOME\Documents\WindowsPowerShell\Modules\DockerCompletion -Recurse -Force
# Download
Invoke-WebRequest https://github.com/matt9ucci/DockerCompletion/archive/master.zip -OutFile master.zip
# Unzip the downloaded archive
Expand-Archive master.zip
# Place the unzipped files and directory in $env:PSModulePath
Move-Item master\DockerCompletion-master\DockerCompletion "$HOME\Documents\WindowsPowerShell\Modules"
# Clean up
Remove-Item master.zip
Remove-Item master -Recurse -Force

$HOME is a PowerShell's automatic variable containing the full path of the user's home directory (in this case C:\Users\matt9ucci).

Import

Execute the following command to check if you can import DockerCompletion:

PS C:\> Get-Module -ListAvailable DockerCompletion

    Directory: C:\Users\matt9ucci\Documents\WindowsPowerShell\Modules

ModuleType Version    Name                                ExportedCommands
---------- -------    ----                                ----------------
Manifest   1.1708.... DockerCompletion

After the check, execute the following command to import the installed module:

Import-Module DockerCompletion

Customization

You can add your own completers and modify default completers with your custom script.

For information about how to write custom scripts, see completers.ps1 and completers4arguments.ps1

To apply your custom script, pass the path as Import-Module's ArgumentList parameter:

Import-Module DockerCompletion -ArgumentList pathto\custom1.ps1, pathto\custom2.ps1

Known Issues

In PowerShell 5.0/5.1, with one dash (-) and double dash (--), completers are not invoked because of a PowerShell's bug. It will be fixed in PowerShell 6.0.

A workaround for this issue is to type a character following - and --. For example, type --a and press tab.

Misc

This github repository will be often rebased.
