Update Elastic Maps Server image

[jsanz]

EMS started to publish additional docker images based on the hardened chainguard-base docker image in 8.14. We don't plan to deprecate the -ubi images, but upgrade to -ubi9 soon but it would be great for ECK users to migrate to the Chainguard base images by default.

For example, for 8.15.0 we have:

• UBI8 image at docker.elastic.co/elastic-maps-service/elastic-maps-server-ubi8:8.15.0
• Aliased UBI image at docker.elastic.co/elastic-maps-service/elastic-maps-server-ubi:8.15.0
• New chainguard image at docker.elastic.co/elastic-maps-service/elastic-maps-server:8.15.0-amd64

New chainguard image at docker.elastic.co/elastic-maps-service/elastic-maps-server:8.15.0-amd64

@jsanz is there are reason we can't have a multi-architecture image with both arm64 and amd64 behind a shared tag e.g. 8.16.0 ?

[pebrc]

Discussed out of band: we should have a multi-arch image for 8.16.0-SNAPSHOT very soon. That means as part of this task we should also remove the restriction on running the e2e tests for both archictures which is currently done via build tags:

cloud-on-k8s/.buildkite/e2e/release-branch-matrix.yaml

Line 64 in 7323879

E2E_TAGS: "es,kb,apm,ent,beat,agent"

^ note that ems is missing from the list above on ARM

Sorry for the unexpected changes, we initially enabled ARM only for master but by the end of last we we also did it to 8.x, my fault for not updating this issue before 😓

With the latest changes we should have the following builds:

• 7.17: amd64 only
  • elastic-maps-server-ubi (based on UBI8)
• 8.15: amd64 only
  • elastic-maps-server-ubi (based on UBI8)
  • elastic-maps-server (based on wolfi)
• 8.16 and later: amd64 and arm64
  • elastic-maps-server-ubi (based on UBI9)
  • elastic-maps-server (based on wolfi)
• 9.0 and later: amd64 and arm64
  • elastic-maps-server-ubi (based on UBI9)
  • elastic-maps-server (based on wolfi)

@jmlrt may keep me honest here, but in case this makes things easier to manage on your end I'd like to add we are also starting to support an alias for wolfi images. Checking the code in the unified release, this will be only the case for 8.16 and later (branches main and 8.x).

@pebrc I see latest SNAPSHOT images for EMS Server 9.0.0 and 8.16.0 on both elastic-maps-service/elastic-maps-server-ubi and elastic-maps-service/elastic-maps-server-wolfi to be multi-arch. Con you confirm if this is working on your end?

@jsanz our e2e tests succeeded last night 👍

Nice!
