v1.7.0

AIS Operator v1.7.0

• Fixed bug with shutdown that could cause a cluster to be stuck in "Shutting Down" state. Operator no longer makes a separate API call to specifically shut down AIS cluster before scaling down.
• Optimize rebalance condition to patch only when changed
• Removed several unused environment variables from the statefulset spec. Refactored construction of the set of ENV vars to use.
• Minor updates to tests, linting, proxy statefulset update status
• Updated all minor dependencies including AIS

Deprecated

• EnablePromExporter option. On all recent AIS releases this is always enabled and the associated environment variable has been removed.

Helm

• Updated CA duration and renewal option in TLS charts
• Added cloud cert secrets generation chart
• Added config for internal test cluster and internal deployment
• Added pod resource values option

v1.6.1

See https://github.com/NVIDIA/ais-k8s/releases/tag/v1.6.0

AIS Operator v1.6.1

• Added reconciliation of target and proxy container resources spec

Full Changelog: v1.6.0...v1.6.1

v1.6.0

IMPORTANT Please see compatibility docs for information on deploying clusters with this new version. It requires a new aisinit container >= v3.25 to generate configs for AIS pods.

AIS Operator v1.6.0

• Added support for init container managed configs. See compatibility docs. This will improve compatibility between versions and help with upgrade paths.
• Operator will now reconcile the entire pod spec for aisnode when image changes
• Operator will now reconcile the entire init pod spec when init image changes
• Added resource management options to AIS spec
• Added MY_NODE env var to aisnode container
• Added support for deployments with distributed tracing

Full Changelog: v1.5.0...v1.6.0

v1.5.0

AIS Operator v1.5.0

• Updated to go 1.23 and latest dependencies
• Added support for custom annotations passed from spec to aisnode containers via Annotations spec option
• Added support for custom environment variables passed from spec to aisnode containers via Env spec option
• Fixed a bug where rebalance would not properly disable and re-enable for upgrades if it had been modified manually
• Removed the option for the operator manager to run external to the k8s cluster
• Internal logic refactoring of AIS API and AuthN clients
• Added Sync option to version config
• Changed net.http.UseHttps option to solely control whether aisnode expects to use HTTPS rather than relying on presence of TLS secrets or cert manager issuer
• Improved logging and requeue logic to make it easier to follow deployment progress and debug issues

Helm

• Moved operator repository to github pages. The operator will now use a constant repo and update chart versions along with each new version. See https://github.com/NVIDIA/ais-k8s/tree/main/helm#install-charts for instructions.

Full Changelog: v1.4.1...v1.5.0

v1.4.1

AIS Operator v1.4.1

• Cleaned up logging and handling of DNS resolution on proxy startup

Major release v1.4.0: https://github.com/NVIDIA/ais-k8s/releases/tag/v1.4.0
Full Changelog: v1.4.0...v1.4.1

v1.4.0

AIS Operator v1.4.0

• Improved state management to reconcile based on state rather than using blocking waits
• Disabled rebalance at the AIS level before cluster modifications -- scaling, rolling upgrades, cluster re-creation
• Added a watch on AIS spec configToUpdate for changes and keep those in sync with the cluster
• Added ability to reconcile statefulset status
• Updated default AIS config generation and improved compatibility through version changes
• Added new AIS states for the following:
  • Scaling
  • HostCleanup
  • Finalized
• Bug fixes
  • Fixed deep equal comparison with spec
  • Fixed cleanup jobs with proper status and termination
  • Improved wait behavior when waiting for AIS cluster readiness or decommissioning
• QOL improvements -- Cleaned up logging, Added unit testing

API Changes

• New options
  • cleanupMetadata -- Allows for cluster decommission while preserving cluster metadata for future deployments
  • tlsCertManagerIssuerName -- Specifies a cert-manager CSI issuer

Full Changelog: v1.3.0...v1.4.0

v1.3.0

AIS Operator v1.3.0

• Added sidecar container for accessing stdout logs via k8s
• Test improvements including unit tests for controller
• Improved state management including new states for in-progress shutdown, in-progress decommission, and cleanup. See ClusterCondition list in aistore_types.go
• Improved state logging and event recording
• Remove unused "env-mount" volume mount

API changes

• New cleanupMetadata option. Previous behavior matches cleanupMetadata=true. This option can now be disabled to allow preservation of cluster metadata (such as buckets) when decommissioning and transitioning to an entirely new cluster (new AIS custom resource).
• New authNSecretName option to add secret signing key for JWT tokens in AIStore.
