Avoid sharing pointers to the same spec data between the informer
and the clusters. The only catch is that the error field is cleared
during deepcopy, since it is an interface that may contain private
fields that cannot be copied, however, the error is only used when
the manifest is parsed and before it is queued, therefore, we never
refer to that field in the cluster structure.
* Sanity checks for the cluster name, improve tests.
- check that the normal and clone cluster name complies with the valid
service name. For clone cluster, only do it if clone timestamp is not
set; with a clone timestamp set, the clone name points to the S3 bucket
- add tests and improve existing ones, making sure we don't call Error()
method for an empty error, as well as that we don't miss cases where
expected error is not empty, but actual call to be tested does not
return an error.
Code review by @zerg-junior and @Jan-M
Allow cloning clusters from the operator.
The changes add a new JSON node `clone` with possible values `cluster`
and `timestamp`. `cluster` is mandatory, and setting a non-empty
`timestamp` triggers wal-e point in time recovery. Spilo and Patroni do
the whole heavy-lifting, the operator just defines certain variables and
gathers some data about how to connect to the host to clone or the
target S3 bucket.
As a minor change, set the image pull policy to IfNotPresent instead
of Always to simplify local testing.
Change the default replication username to standby.
* client-go v4.0.0-beta0
* remove unnecessary methods for tpr object
* rest client: use interface instead of structure pointer
* proper names for constants; some clean up for log messages
* remove teams api client from controller and make it per cluster
