This PR is regarded with #14748

Just a PR to add e2e test for Arm64 to check if it is green.
If the job is OK, will change it to a periodical job.

@dims @geetasg @chaochn47 first time commit here, so needs maintainers to approve first. Thanks!

I think we need to add similar tests (see below) for ARM64,

• https://github.com/etcd-io/etcd/blob/main/.github/workflows/tests.yaml
• https://github.com/etcd-io/etcd/blob/main/.github/workflows/e2e.yaml

And remove https://github.com/etcd-io/etcd/blob/main/.github/workflows/functional-arm64.yaml

Hi @ahrtr, thanks!
This one is to add e2e test for Arm64 to verify the function.
After it work, I will add the integration test in the tests.yaml and remove the functional test since it is going to be deprecated.

The reason why it is located to a separate file is that it needs to run on a special Arm64 node and also this will be changed to periodical job.

Instead of adding a separate workflow, can you add arm64 as a job to existing "E2E" workflow?

[ahrtr]

It doesn't work because the ARM machines have different labels. FYI. #15172 (comment)

Probably we can add a template to be shared by both the existing E2E workflow and ARM64. But I don't think it's a big deal, It's OK to leave it as it's for now.

[serathius]

Labels are per job not per workflow.

jobs:
  test:
    runs-on: [Linux, ARM64]

You can change it to:

jobs:
  amd64:
    runs-on: ubuntu-latest
    ...
  arm64:
    runs-on: [Linux, ARM64]

[ahrtr]

this will be changed to periodical job.

Why?

[dims]

Why?

@ahrtr the aim is not to be a bottleneck to the current set of CI jobs that are run before we land a PR. The problem is we have only 2 github runners for arm64 and if we have a lot of PRs in flight the time that folks have to wait to land something will be a lot.

Makes sense. Thanks @dims for the clarification.
