docker-compose-exec

A CLI tool for discovering Docker Compose files and their services across multiple directories.
Select a Compose file and service interactively, then execute a custom command on the service.

Features

• Automatically searches for Docker Compose files (docker-compose.yml, compose.yml, etc.) in predefined paths.
• Interactive terminal-based UI for selecting Compose files and services.
• Executes a configurable shell command on the selected service.

Installation

1. Download the latest release binary from the releases page.

   wget https://github.com/doppelar0n/docker-compose-exec/releases/latest/download/docker-compose-exec-amd64

2. Copy the binary to /usr/local/bin:

   sudo mv docker-compose-exec-amd64 /usr/local/bin/docker-compose-exec

3. Make the binary executable:

   sudo chmod +x /usr/local/bin/docker-compose-exec

Usage

Just run:

docker-compose-exec

This launch the tool with default paths and interactive UI.

Optional Environment Variables

You can configure the following environment variables:

• CONTAINER_BASE_PATH Specify paths to search for Docker Compose files (colon-separated). Example:

  export CONTAINER_BASE_PATH="/path/to/containers:/another/path"

  Default paths include /var/container and /srv/container.
• CONTAINER_EXEC_COMMAND Customize the execution command. Example:

  export CONTAINER_EXEC_COMMAND="docker compose -f %COMPOSE exec --user root %SERVICE /bin/bash"

  • %COMPOSE will be replaced with the path to the selected Compose file.
  • %SERVICE will be replaced with the selected service.

Example

Imagine you have the following directory structure:

/var/container
├── project1/
│   └── docker-compose.yml
├── project2/
│   └── compose.yml
/srv/container
└── project3/
    └── docker-compose.yaml

Running docker-compose-exec will:

• Discover these Compose files.
• Allow you to select a file (e.g., project1/docker-compose.yml).
• List available services from the selected file.
• Execute the configured command (e.g., docker exec) on the chosen service.

more Examples:

• Specify custom search paths for Compose files.

  CONTAINER_BASE_PATH="/var/mycontainers:/srv/containers" docker-compose-exec

• Use a custom execution command.

  CONTAINER_EXEC_COMMAND="docker compose -f %COMPOSE exec %SERVICE /bin/bash" docker-compose-exec

• This is like dry run. (--dry-run)

  CONTAINER_EXEC_COMMAND="echo %COMPOSE %SERVICE" docker-compose-exec
