Gokku

Appearance

CLI Reference ​

Complete command-line interface reference for Gokku.

Installation ​

Client (Local Machine) ​

bash
curl -fsSL https://gokku-vm.com/install | bash -s -- --client

Server ​

bash
curl -fsSL https://gokku-vm.com/install | bash -s -- --server

Global Options ​

  • -a, --app <app-name> - Specify app name (e.g., api-production, vad-staging)
  • --version, -v - Show version information
  • --help, -h - Show help information

The -a/--app flag uses your git remote name:

  • Must be a configured git remote
  • Gokku runs git remote get-url <name> to extract connection info
  • Environment is parsed from the remote name suffix

How it works:

  1. You add a git remote (standard git command):

    bash
    git remote add api-production ubuntu@server:api
git remote add vad-staging ubuntu@server:vad

  2. Gokku parses the remote URL to extract:

    • SSH host: ubuntu@server
    • App name: api (from /repos/api.git)

  3. You use the app name directly:

    bash
    gokku config set PORT=8080 -a api-production
gokku logs -a vad-staging -f

bash
gokku apps list -a api-production

gokku apps create <app> ​

Create a new application.

bash
gokku apps create myapp -a myapp

gokku apps destroy <app> ​

Destroy an application.

bash

Configuration ​

gokku config set KEY=VALUE [-a <app>] ​

Set environment variables.

bash
# Remote execution
gokku config set PORT=8080 -a api-production
gokku config set DATABASE_URL="postgres://..." -a api-production

# Local execution (on server)
gokku config set PORT=8080 --app api

gokku config get KEY [-a <app>] ​

Get environment variable value.

bash
gokku config get PORT -a api-production

gokku config list [-a <app>] ​

List all environment variables.

bash

Execution ​

gokku run <command> [-a <app>] ​

Run arbitrary commands inside the application container.

bash
# Remote execution (inside container)
gokku run bundle exec rails console -a api-production
gokku run npm install -a myapp
gokku run python manage.py shell -a django-app

# Local execution (on server, inside container)
gokku run bundle exec rails console --app api

Security Note: Commands are executed inside the application's Docker container (named after the app), not directly on the server. This provides isolation and security.

Container Naming: The container name matches the application name (e.g., stt, api-production).
