azp-k8s-agent-scaler-operator-0.2.0

Azure Pipelines Kubernetes-based agent scaler operator

Changes:

• Bump versions of Go and various libraries, fixes all known vulnerabilities
• Fix regex validation pattern for NormalOfflineAgentDeletionMinAge, DummyAgentDeletionMinAge and DummyAgentGarbageCollectionInterval, only quantities with a single quantity were allowed, e.g. "5m", now also values like "1h20m" are considered valid
• Add configurable AgentMinIdlePeriod to CR: it defines how long the controller waits before it terminates an idle Pod
• Improve various debug logs
• Fix bug that agent Pods were not cleaned properly under certain conditions

azp-k8s-agent-scaler-operator-0.1.9

Azure Pipelines Kubernetes-based agent scaler operator

Changes:

• Fix premature Pod termination
• Improve logging at various places
• Print pending jobs (if they changed) in each reconcile loop
• Improve timestamp precision to nanoseconds

azp-k8s-agent-scaler-operator-0.1.8

Azure Pipelines Kubernetes-based agent scaler operator

Changes:

• New debug mode that prints additional data from the Azure Pipeline APIs: it can be temporarily enabled: execute into the controller container, run touch /home/nonroot/debug to enable debug printing, delete the file with rm to disable debug printing again

azp-k8s-agent-scaler-operator-0.1.7

Azure Pipelines Kubernetes-based agent scaler operator

Changes:

• Improve the stability of the reusable cache volumes usage, by always sorting the reusable cache volumes first (alphabetically by their name), before picking the first available one
• Create at most maxCount PVCs of a reusable cache volume - if all PVCs are currently in use, delay the creation of Pods until one becomes available
• Make various aspects of garbage collection of offline agents configurable in the CR

azp-k8s-agent-scaler-operator-0.1.6

Azure Pipelines Kubernetes-based agent scaler operator

Bug fixes:

• Update registered dummy agents whenever the CR content changes
• Incorrect caching of Pool IDs (retrieved from the pool name)
• ExtraAgentContainers environment variable was set twice on the AZP agent container

azp-k8s-agent-scaler-operator-0.1.5

Azure Pipelines Kubernetes-based agent scaler operator

Changes:

• Fix handling of ExtraAgentContainers parsing

azp-k8s-agent-scaler-operator-0.1.4

Azure Pipelines Kubernetes-based agent scaler operator

Changes:

• Controller no longer sets the working directory for containers created for ExtraAgentContainers --> K8s should use the WORKDIR defined by the image's Dockerfile
• ExtraAgentContainers demand now expects named attributes (name, image, cpu, memory, the last 2 are optional), e.g. name=ubuntu,image=docker.io/library/ubuntu:22.04,cpu=250m,memory=64Mi

demo-agent-0.1.2

Demonstration chart that sets up Azure Pipeline Agents capable of running jobs with multiple containers

Changes:

• Excluding buildkit container from AppArmor limitations (introducing pod-specific annotations)
• Allow setting pod-specific securityContexts

azp-k8s-agent-scaler-operator-0.1.3

Azure Pipelines Kubernetes-based agent scaler operator

Changes:

• Implement AZP API spam protection: repeat reconciliation every 5 seconds, or when the CR changes. Previously, Reconcile() of the operator was called on every CR and Pod change, the latter could happen very frequently and hammer the AZP API
• Also terminate agent pods that are not even scheduled yet or whose AZP container is not running yet
