In case the whole annotation changes (like the external DNS) we
don't want to keep the old one hanging around. Unline specs, we
don't expect anyone except the operator to change the annotations.
Use StrategicMergePatchType in order to replace the annotations
map completely.
The flag adds a replica service with the name cluster_name-repl and
a DNS name that defaults to {cluster}-repl.{team}.{hostedzone}.
The implementation converted Service field of the cluster into a map
with one or two elements and deals with the cases when the new flag
is changed on a running cluster
(the update and the sync should create or delete the replica service).
In order to pick up master and replica service and master endpoint
when listing cluster resources.
* Update the spec when updating the cluster.
In order to support volumes different from EBS and filesystems other than EXT2/3/4 the respective code parts were implemented as interfaces. Adding the new resize for the volume or the filesystem will require implementing the interface, but no other changes in the cluster code itself.
Volume resizing first changes the EBS and the filesystem, and only afterwards is reflected in the Kubernetes "PersistentVolume" object. This is done deliberately to be able to check if the volume needs resizing by peeking at the Size of the PersistentVolume structure. We recheck, nevertheless, in the EBSVolumeResizer, whether the actual EBS volume size doesn't match the spec, since call to the AWS ModifyVolume is counted against the resize limit of once every 6 hours, even for those calls that shouldn't result in an actual resize (i.e. when the size matches the one for the running volume).
As a collateral, split the constants into multiple files, move the volume code into a separate file and fix minor issues related to the error reporting.
Updates to statefulset spec for fields other than 'replicas' and
containers' are forbidden. However, it is possible to delete the old
statefulset without deleting its pods and create the new one, using the
changed specs. The new statefulset shall pick up the orphaned pods.
Change the statefulset's comparison to return the combined effect of
all checks, not just the first non-matching field.
Allow disabling access to the DB and the Teams API.
Command-line options --nodatabaseaccess and --noteamsapi disable all
teams api interaction and access to the Postgres database. This is
useful for debugging purposes when the operator runs out of cluster
(with --outofcluster flag).
The same effect can be achieved by setting enable_db_access and/or
enable_teams_api to false.
