Reclient

Reclient integrates with an existing build system to enable remote execution and caching of build actions.

Electron has a deployment of a reclient compatible RBE Backend that is available to all Electron Maintainers. See the Access section below for details on authentication. Non-maintainers will not have access to the cluster, but can sign in to receive a Cache Only token that gives access to the cache-only CAS backend. Using this should result in significantly faster build times .

Enabling Reclient

Currently the only supported way to use Reclient is to use our Build Tools. Reclient configuration is automatically included when you set up build-tools.

If you have an existing config, you can just set "reclient": "remote_exec" in your config file.

Building with Reclient

When you are using Reclient, you can run autoninja with a substantially higher j value than would normally be supported by your machine.

Please do not set a value higher than 200. The RBE system is monitored. Users found to be abusing it with unreasonable concurrency will be deactivated.

autoninja -C out/Testing electron -j 200

If you're using build-tools, appropriate -j values will automatically be used for you.

Access

For security and cost reasons, access to Electron's RBE backend is currently restricted to Electron Maintainers. If you want access, please head to #access-requests in Slack and ping @infra-wg to ask for it. Please be aware that being a maintainer does not automatically grant access. Access is determined on a case-by-case basis.

Support

We do not provide support for usage of Reclient. Issues raised asking for help / having issues will probably be closed without much reason. We do not have the capacity to handle that kind of support.
