# Workflows
|
||
- [Events](https://docs.github.com/en/actions/using-workflows/events-that-trigger-workflows) trigger workflows
|
||
- Workflows contain jobs
|
||
- Jobs contain steps
|
||
- Steps are commands or actions
|
||
|
||
---
|
||
|
||
|
||
# Jobs
|
||
- Workflows can contain multiple jobs
|
||
- Jobs run in parallel by default
|
||
- Each job runs on a [Runner](https://docs.github.com/en/actions/using-github-hosted-runners/about-github-hosted-runners)
|
||
- Steps and Shell Commands run in sequence
|
||
|
||
---
|
||
|
||
# Runners
|
||
|
||
- Specify the type of runner with `runs-on` (e.g., `ubuntu-latest`).
|
||
- GitHub provisions a new VM for each job.
|
||
- Steps in a job share information using the runner's filesystem.
|
||
- VM is decommissioned after job completion.
|
||
|
||
---
|
||
|
||
# Supported runners and hardware
|
||
|
||
- GitHub-hosted runner application is open source.
|
||
- OS: Windows, Linux, and macOS
|
||
- Runners include preinstalled software, updated weekly.
|
||
- There are also Large Hosted Runners
|
||
- Self-Hosted Runners
|
||
- You can install additional software on runners.

<div class="columns">
|

<div>
|
||
|
||
- Never use structured data as a secret
|
||
- Register all secrets used within workflows
|
||
- Audit how secrets are handled
|
||
- Use credentials that are minimally scoped
|
||
- Audit and rotate registered secrets
|
||
- Consider requiring review for access to secrets

</div>
|

<div>
|
||
|
||
- Use an action instead of an inline script (recommended)
|

- Use an intermediate environment variable
|

- Use OpenID Connect to access cloud resources

- Pin third-party actions to a full length commit SHA

# Bonus - Private Networking
|
||
|
||
- GitHub Actions is triggered.
|
||
- Actions service creates a runner.
|
||
- The runner service deploys the GitHub-hosted runner's NIC into your Azure VNET.
|
||
- The runner agent picks up the workflow job.
|
||
- The runner sends logs back to the GitHub Actions service.
|
||
- NIC accesses private resources.
