v0.37.0

[machine-controller-manager]

⚠️ Breaking Changes

• [DEVELOPER] machine-controller-manager now checks for misconfigured PodDisruptionBudgets (ones that require zero voluntary evictions and make impossible the graceful Node drain) and sets better Machine .status.lastOperation.description for such Machines. This change is breaking as out-of-tree providers need new RBAC permissions - list and watch access for PodDisruptionBudgets in the target cluster. (#591, @ialidzhikov)

🏃 Others

• [OPERATOR] Avoid the deletion of the machines in CrashLoopBackoff state by the safety controller (#589, @AxiomSamarth)

v0.36.0

[machine-controller-manager]

✨ New Features

• [OPERATOR] All machine classes do now support an optional .{spec.}credentialsSecretRef field in addition to today's .{spec.}secretRef field. If .{spec.}credentialsSecretRef is non-nil then the provider credentials will be read out of this secret. The user-data for the machine bring-up is still required to be part of the secret referenced by .{spec.}secretRef. (#578, @rfranzke)
• [OPERATOR] Some machine class secrets are now supporting alternative data keys: (#578, @rfranzke)
  • The machine class secret for Alicloud machines does now also accept the data keys accessKeyID and accessKeySecret as alternatives for today's keys.
  • The machine class secret for AWS machines does now also accept the data keys accessKeyID and secretAccessKey as alternatives for today's keys.
  • The machine class secret for Azure machines does now also accept the data keys clientID, clientSecret, subscriptionID and tenantID as alternatives for today's keys.
  • The machine class secret for GCP machines does now also accept the data key serviceaccount.json as alternatives for today's key.

🏃 Others

• [OPERATOR] Bumped AWS SDK version to v1.23.13 (#580, @zjj2wry)
• [OPERATOR] An issue causing panic when the encoded machine template hash length is less than expect limit is now fixed. (#575, @ialidzhikov)
• [OPERATOR] MCM will delete Azure machines even if the underlying resource group is already deleted. (#566, @dkistner)
• [OPERATOR] Set Machine Phase to Terminating before draining. (#564, @prashanth26)

• [USER] AWS: Allows deletion of machines even on modify instance call failure (#515, @prashanth26)
