Highlights of EDB Postgres for Kubernetes 1.8.7
- Changed the default value of
stopDelayto 1800 seconds instead of 30 seconds - Introduced a new parameter, called
smartShutdownTimeout, to control the window of time reserved for the smart shutdown of Postgres to complete; the general formula to compute the overall timeout to stop Postgres ismax(stopDelay - smartShutdownTimeout, 30) - Changed the default value of
startDelayto 3600, instead of 30 seconds - Replaced the livenessProbe initial delay with a more proper Kubernetes startup probe to deal with the start of a Postgres server
- Changed the default value of
switchoverDelayto 3600 seconds instead of 40000000 seconds
Additionally, this release of EDB Postgres for Kubernetes includes the following:
| Type | Description |
|---|---|
| Security fix | Added a default seccompProfile to the operator deployment. |
| Enhancement | Introduced the k8s.enterprisedb.io/coredumpFilter annotation to control the content of a core dump generated in the unlikely event of a PostgreSQL crash, by default set to exclude shared memory segments from the dump. |
| Enhancement | Allowed configuration of ephemeral-storage limits for the shared memory and temporary data ephemeral volumes. |
| Enhancement | Validation of resource limits and requests through the webhook. |
| Enhancement | Ensure that PostgreSQL's shared_buffers are coherent with the pods' allocated memory resources. |
| Enhancement | Added uri and jdbc-uri fields in the credential secrets to facilitate developers when connecting their applications to the database. |
| Enhancement | Added a new phase, Waiting for the instances to become active, for finer control of a cluster's state waiting for the replicas to be ready. |
| Enhancement | Improved detection of Pod rollout conditions through the podSpec annotation. |
| Enhancement | Added primary timestamp and uptime to the kubectl plugin's status command. |
| Technical enhancement | Replaced k8s-api-docgen with gen-crd-api-reference-docs to automatically build the API reference documentation. |
| Bug fix | Ensure that the primary instance is always recreated first by prioritizing ready PVCs with a primary role. |
| Bug fix | Honor the k8s.enterprisedb.io/skipEmptyWalArchiveCheck annotation during recovery to bypass the check for an empty WAL archive. |
| Bug fix | prevent a cluster from being stuck when the PostgreSQL server is down but the pod is up on the primary. |
| Bug fix | Avoid treating the designated primary in a replica cluster as a regular HA replica when replication slots are enabled. |
| Bug fix | Reconcile services every time the selectors change or when labels/annotations need to be changed. |
| Bug fix | Default to app for both the owner and database during recovery bootstrap. |
| Bug fix | Avoid write-read concurrency on cached cluster. |
| Bug fix | Remove empty items, make them unique and sort in the ResourceName sections of the generated roles. |
| Bug fix | Ensure that the ContinuousArchiving condition is properly set to 'failed' in case of errors. |
| Bug fix | Reconcile PodMonitor labels and annotations. |
| Bug fix | Fixed backup failure due to missing RBAC resourceNames on the Role object. |
| Observability | Added TCP port label to default pg_stat_replication metric. |
| Observability | Fixed the pg_wal_stat default metric for Prometheus. |
| Observability | Improved the pg_replication default metric for Prometheus |
| Observability | Used alertInstanceLabelFilter instead of alertName in the provided Grafana dashboard |
| Observability | Enforce standard_conforming_strings in metric collection. |
| Change | Set the default operand image to PostgreSQL 16.0. |
| Change | Fencing now uses PostgreSQL's fast shutdown instead of smart shutdown to halt an instance. |
| Change | Rename webhooks from kb.io to k8s.enterprisedb.io group. |
| Change | Added the k8s.enterprisedb.io/instanceRole label and deprecated the existing role label. |
