Skip echo-based policy when deploy-on-self-hosted-vm installs the agent

When the agent is installed via deploy-on-self-hosted-vm, the config already contains egress_policy and allowed_endpoints. Skip the sendAllowedEndpoints echo to avoid a second applyEgressPolicy that may interfere with the config-based block policy.
Add api_key to self-hosted agent config for event upload authentication

 ## Limitations

 ### GitHub-Hosted Runners
-
-* Only Ubuntu VM is supported. Windows and MacOS GitHub-hosted runners are not supported. There is a discussion about that [here](https://github.com/step-security/harden-runner/discussions/121).
-* Harden-Runner is not supported when [job is run in a container](https://docs.github.com/en/actions/using-jobs/running-jobs-in-a-container) as it needs sudo access on the Ubuntu VM to run. It can be used to monitor jobs that use containers to run steps. The limitation is if the entire job is run in a container. That is not common for GitHub Actions workflows, as most of them run directly on `ubuntu-latest`. Note: This is not a limitation for Self-Hosted runners.
+* Harden-Runner is not supported when [job is run in a container](https://docs.github.com/en/actions/using-jobs/running-jobs-in-a-container) with built-in labels such as `ubuntu-latest`, as it needs sudo access on the Ubuntu VM to run. The limitation is if the entire job is run in a container. However, such jobs can be monitored when using custom VM images with GitHub-hosted runners. This is also not a limitation for Self-Hosted runners.

 ### Self-Hosted Actions Runner Controller (ARC) Runners

 * Since ARC Harden Runner uses eBPF, only Linux jobs are supported. Windows and MacOS jobs are not supported.

Author	SHA1	Message	Date
Varun Sharma	d2d83c9c60	Skip echo-based policy when deploy-on-self-hosted-vm installs the agent When the agent is installed via deploy-on-self-hosted-vm, the config already contains egress_policy and allowed_endpoints. Skip the sendAllowedEndpoints echo to avoid a second applyEgressPolicy that may interfere with the config-based block policy.	2026-04-14 23:05:18 -07:00
Varun Sharma	03c6aeecac	Add api_key to self-hosted agent config for event upload authentication The agent needs an api_key to authenticate with the API for uploading process and file events. Generate a random UUID as api_key matching the approach used in the self-hosted branch.	2026-04-13 17:32:58 -07:00
Varun Sharma	bb4b9e732d	Address Copilot review: cache isDocker/isAgentInstalled calls, rename test file Compute isDocker() and isAgentInstalled() once and reuse for both the deploy check and logging. Rename setup.test.ts to utils.test.ts to match the module it tests.	2026-04-12 20:58:46 -07:00
Varun Sharma	b62162e11d	Fix isAgentInstalled tests to mock fs.existsSync Tests failed on CI because the runner had agent.status present. Mock fs.existsSync to make tests environment-independent.	2026-04-12 20:45:19 -07:00

Varun Sharma	b5eed58f5d	Update agent-ebpf to v1.8.0 with global block list support	2026-04-12 20:22:02 -07:00
Varun Sharma	ac89272860	Add deploy-on-self-hosted-vm option for agent installation on self-hosted runners Installs the Harden Runner agent on self-hosted Linux VMs when enabled. Skipped if running in a container or agent is already installed. Recommended only for ephemeral runners when baking the agent into the VM image is not possible. Includes unit tests.	2026-04-12 20:18:10 -07:00
