rCOMM53b4f3fab8d8: [CI] Add `identity_build` workflow to Buildkite/GH Actions

Summary

This was previously handled as part of the "Services CI" workflow that will be deprecated later in this stack. This diff allows us to increase concurrency as we move over to the autoscaling EC2 instances.

Differences on the Buildkite side:

We use the actual shell command instead of yarn blah because the autoscaling instances are intended to be as minimal as possible and don't include node, yarn, etc.

We use the --no-cache flag to force a new complete build on each run. The previous "Services CI" workflow depended heavily on caches, because running 3-4 complete builds would take a long time. Now, we can separate these out and take advantage of the concurrency provided by the autoscaling instances.

Depends on D4390

Test Plan

Buildkite: Copy/pasted from what I have in the Buildkite GUI that has been "active" for the last 2-3 days without issue.

GitHub: Will see what happens when it lands, but fairly confident it should be good to go.

.github/workflows/identity_build.yaml
19	I tried to keep this consistent with the "names" of steps we use in the other GitHub Actions workflows where we just match the name of the command. It's also convenient in the GH actions workflow run page to see exactly what command was run for each step without having to "expand" it.

We use the --no-cache flag to force a new complete build on each run. The previous "Services CI" workflow depended heavily on caches, because running 3-4 complete builds would take a long time. Now, we can separate these out and take advantage of the concurrency provided by the autoscaling instances.

It isn't too intuitive that avoiding cache would improve performance. So basically, using caches stopped us from using autoscaling, and now the builds will take more time that can be shared between more instances, so overall the performance will be better, right? Do we know how the resources usage will grow after this change?

rebase after cherrypicking and before landing

It isn't too intuitive that avoiding cache would improve performance. So basically, using caches stopped us from using autoscaling, and now the builds will take more time that can be shared between more instances, so overall the performance will be better, right? Do we know how the resources usage will grow after this change?

Ah so two separate things. One is that we want to avoid using caches because there was some strange behavior observed during the Keyserver docker work with caches. Avoiding caches will strictly hurt performance, but we still deemed it the correct thing to do.

However, if we were to avoid the caches and do 4 full builds in a single workflow, it might take 20 minutes. By breaking them into 4 separate workflows that take 5 minutes each for example, we can get complete builds while still ensuring that the wait time is acceptable thanks to autoscaling.

This revision was landed with ongoing or failed builds.Jul 1 2022, 12:49 PM
