Debug your GitHub Actions by using tmate

This GitHub Action offers you a direct way to interact with the host system on which the actual scripts (Actions) will run.

Features

• Debug your GitHub Actions by using SSH
• Continue your Workflows afterwards

Supported Operating Systems

• Linux
• macOS
• Windows

Getting Started

By using this minimal example a tmate session will be created.

name: CI
on: [push]
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v2
    - name: Setup tmate session
      uses: mxschmitt/action-tmate@v3

To get the connection string, just open the Checks tab in your Pull Request and scroll to the bottom. There you can connect either directly per SSH or via a web based terminal.

Without sudo

By default we run the commands using sudo. If you get sudo: not found you can use the parameter below to execute the commands directly.

name: CI
on: [push]
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v2
    - name: Setup tmate session
      uses: mxschmitt/action-tmate@v3
      with:
        sudo: false

Continue a workflow

If you want to continue a workflow and you are inside a tmate session, just create a empty file with the name continue either in the root directory or in the project directory by running touch continue or sudo touch /continue.

Connection string / URL is not visible

The connection string will be written in the logs every 5 seconds. For more information checkout issue #1.
