breakpoint

namespacelabs/breakpoint is a GitHub action that allows you to pause the execution of a workflow, enter a live SSH session, debug the environment and finally resume the run when you are done.

Workflows that have active breakpoint sessions are still "running" and continue to count towards your total CI usage.

Example

jobs:
  go-tests:
    runs-on: ubuntu-latest
 
    steps:
      - name: Checkout
        uses: actions/checkout@v3
 
      - name: Run Go tests
        runs: |
          go test ./...
 
      - name: Breakpoint if tests failed
        if: failure()
        uses: namespacelabs/breakpoint-action@v0
        with:
          duration: 30m
          authorized-users: jack123, alice321

When the above breakpoint runs, you'll see a log message like the following:

┌───────────────────────────────────────────────────────────────────────────┐
│                                                                           │
│ Breakpoint running until 2023-05-24T16:06:48+02:00 (29 minutes from now). │
│                                                                           │
│ Connect with: ssh -p 40812 runner@rendezvous.namespace.so                 │
│                                                                           │
└───────────────────────────────────────────────────────────────────────────┘

The SSH service in breakpoint only accepts sessions from public SSH keys configured by GitHub users, listed by authorized-users.

And there you have it, an SSH session to connect to debug your workflow.
