In Kubernetes, there is tight coupling of API group, CRD and Custom Resources managed by operators. CRDs are cluster resource and unique per cluster.
CRD operatorconfigurations.acid.zalan.do defines the operator configurations for postgres operator.
CRD postgresqls.acid.zalan.do defines minimum and maximum supported postgresql versions.
This leads to issues in a multi-tenant k8s cluster, an example provided below.
In Namespace X, user X deploys web tier application which uses zalando postgres-operator with max version PG 15.
In Namespace Y, user Y deploys web tier application which also uses zalando postgres-operator but needs PG 17 runs into an issue as CRD postgresqls.acid.zalan.do supports only PG 15. This happens because CRD is cluster scope and all namespace scoped applications should adhere to it.
With large k8s clusters, postgresql being a very popular database, zalando postgres operator being defacto way to manage databases, there is a need to keep this configurable so applications can manage the API group of CRDs.
Take API group for postgres operator as an env variable, assuming that the relevant CRDs with API groups are installed.
Create the second PDB to cover Pods with a special "critical operation" label set.
This label is going to be assigned to all pg cluster's Pods by the Operator during a PG major version upgrade, by Patroni during a cluster/replica bootstrap. It can also be set manually or by any other automation tool.
* Feat: Support Running Sidecard with a Command.
This PR addresses issue #2448 . Some containers may not have entry points, if this is the case they would need to be run using a command. This change extends the definition of sidecar so that there is an optional command field. If the field is present then the container will be run using that command. This is a two line change that is fully backward compatible.
