PostgreSQL Proxy over SSH GitHub Action

This GitHub Action creates a proxy for PostgreSQL over SSH

The base-image (drinternet/rsync) of this action is very small and is based on Alpine 3.15.0 (no cache) which results in fast deployments.

---

Inputs

• postgre_host - The PostgreSQL server hostname or IP

• postgre_port - The PostgreSQL server port

• remote_host* - The remote SSH hostname or IP

• remote_port - The remote SSH port. Defaults to 22

• remote_user* - The remote SSH username

• remote_key* - The remote SSH keyfile

• remote_key_pass - The remote SSH keyfile passphrase (if any)

• switches - Extra OpenSSH client flags/switches, eg: -A

* = Required

Required secret(s)

This action needs secret variables for the SSH private key of your key pair. The public key part should be added to the authorized_keys file on the server that receives the deployment. The secret variable should be set in the Github secrets section of your org/repo and then referenced as the remote_key input.

Always use secrets when dealing with sensitive inputs!

For simplicity, we are using DEPLOY_* as the secret variables throughout the examples.

Example usage

Simple:

name: DEPLOY
on:
  push:
    branches:
    - master

jobs:
  deploy:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v2
    - name: Setup PostgreSQL proxy
      uses: virbyte/postgresql-proxy-action
      with:
        remote_host: example.com
        remote_user: username
        remote_key: ${{ secrets.DEPLOY_KEY }}

Advanced:

jobs:
  deploy:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v2
    - name: Setup PostgreSQL proxy
      uses: burnett01/[email protected]
      with:
        postgre_host: localhost
        postgre_port: 5432
        remote_host: example.com
        remote_port: 2222
        remote_user: username
        remote_key: ${{ secrets.DEPLOY_KEY }}

For better security, I suggest you create additional secrets for remote_host, remote_port, remote_user and remote_path inputs.

jobs:
  deploy:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v2
    - name: rsync deployments
      uses: burnett01/[email protected]
      with:
        switches: -avzr --delete
        path: src/
        remote_path: ${{ secrets.DEPLOY_PATH }}
        remote_host: ${{ secrets.DEPLOY_HOST }}
        remote_port: ${{ secrets.DEPLOY_PORT }}
        remote_user: ${{ secrets.DEPLOY_USER }}
        remote_key: ${{ secrets.DEPLOY_KEY }}

If your private key is passphrase protected you should use:

jobs:
  deploy:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v2
    - name: rsync deployments
      uses: burnett01/[email protected]
      with:
        switches: -avzr --delete
        path: src/
        remote_path: ${{ secrets.DEPLOY_PATH }}
        remote_host: ${{ secrets.DEPLOY_HOST }}
        remote_port: ${{ secrets.DEPLOY_PORT }}
        remote_user: ${{ secrets.DEPLOY_USER }}
        remote_key: ${{ secrets.DEPLOY_KEY }}
        remote_key_pass: ${{ secrets.DEPLOY_KEY_PASS }}
