[get.jenkins.io] migrate from mirrorbits to mirrorbits-parent chart

[dduportal]

Service(s)

Azure, get.jenkins.io

Summary

Following the work done in #3619 and #2649 , we have to update the service get.jenkins.io in jenkins-infra/kubernetes-management to use the mirrorbits-parent chart instead of the current (and soon to be removed) mirrorbits.

• It will allows us to use the latest improvements we did on the chart and config management (logs mangement, debugging mirrorbits, umbrella storage and ingress, etc.)
• It will allows migrating the httpd server to arm64 for get.jenkins.io

Reproduction steps

No response

Preliminary step: defines archives.jenkins.io as fallback instead of the 2 OSUOSL:

• Since Move archives.jenkins.io service away from Oracle #3760, archives.jenkins.io runs in DigitalOcean (in Frakfurt, Germany, datacenter) and the download bandwitdh is good and cheap
• As pert In reference to issue #3183 #3338 (and many other issues), OSUOSL seems to purge some data after some time while archives.jenkins.io does not

• Applied with success (https://github.com/jenkins-infra/charts-secrets/commit/e064818e223df5fa6659d0a236017d23fff554d3 - private commit)
• Opened open get.jenkins.io maintenance operation status#457 to annoucne operation

[dduportal]

Update:

• Opened feat(publick8s) install a new instance of get.jenkins.io with mirrorbits-parent chart kubernetes-management#4847

  • First commit is the expected config
  • Second commit restricts domain and RedisDB for the initial installation (easier to revert).

• Starting initial installation

[dduportal]

Update:

• Initial (manual) installation is successful
• feat(publick8s) install a new instance of get.jenkins.io with mirrorbits-parent chart kubernetes-management#4847 merged

Todo:

• Manual operation: for migration:
  • Set up to proper domains and RedisDB on the new get.jenkins.io
  • Remove ingress of mirrorbits
  • Scale mirrorbits to zero
• Validate: if it works, then remove namespace and config for old mirrorbits, otherwise rollback

[dduportal]

Update:

• PR for migration opened, applied and deployed. Led to a 2 min downtime: breaking(publick8s) migrate get.jenkins.io to the new instance kubernetes-management#4848 (comment)
• Merged but jenkins-infra/kubernetes-management is failing to re-apply the chart. WiP

[dduportal]

Update:

• jenkins-infra/kubernetes-management is OK for get-jenkins-io ✅
• Removed the former PV mirrorbits-binary

Todo:

• Cleanupo helm-charts repository and updatecli manifests

Cleanupo helm-charts repository and updatecli manifests

Will it include the renaming of mirrorbits-parent to mirrorbits? (Please say yes ^^)

mirrorbits-lite by mirrorbits you mean? ;)

[dduportal]

• Chart renamed in cleanup: remove legacy mirrorbits chart and rename mirrorbits-lite to mirrorbits 1/2 helm-charts#1006
• Chart mirrorbits-parent updated in cleanup!(mirrorbit-parent) change dependency to support renaming of mirrorbits-lite to mirrorbits. BREAKING. helm-charts#1007

Todo:

• wait for the 2.0.0 release of mirrorbits-parent in jenkins-infra/kubernetes-management
• change chart values and deploy it

[dduportal]

Update:

• All charts were released/updated properly
• PR Bump mirrorbits-parent helm chart version to 2.0.1 kubernetes-management#4853 to use the new charts is ready, with a fixup commit to change parameters.
