* Avoid "bulk-comparing" pod resources during sync.
First attempt to fix bogus restarts due to the reported mismatch
of container resources where one of the resources is an empty struct,
while the other has all fields set to nil.
In addition, add an ability to set limits and requests per pod, as well as the operator-level defaults.
* Add version label to the cluster.
According to the STUPS team the daemon that exports logs to scalyr
stops the export if the version label is missing.
* Move label names to constants.
* Run go fmt
* Add infrastructure roles configured globally.
Those are the roles defined in the operator itself. The operator's
configuration refers to the secret containing role names, passwords
and membership information. While they are referred to as roles, in
reality those are users.
In addition, improve the regex to filter out invalid users and
make sure user secret names are compatible with DNS name spec.
Add an example manifest for the infrastructure roles.
- Use the branch of pretty with this feature fixed:
https://github.com/kr/pretty/pull/42
- Add the Limit to the resources declaration to avoid dummy
differences between statefulsets (where both Resource structures
are empty, but in one case the fields are not mentioned, while
in another they are assigned to empty values).
Conceptually, the operator's task is just to change the pod. As it
has no influence over the role the pod will take (either the master
or a replica), it shouldn't wait for the specific role.
This fixes at least one issue, where the pod running in a single-pod
cluster has been waited for forever by the operator expecting it to
have a wrong role (since Patroni callback assiging it the original
replica role has been killed after a quick promote by the next
callback.)
- Set WAL_S3_BUCKET to point WAL-E where to fetch/store WAL files
- Set annotations/iam.amazonaws.com/role to set the role to access AWS"
The new env vairables are PGOP_WAL_S3_BUCKET and PGOP_KUBE_IAM_ROLE.
- add a new environment variable for triggering debug log level
- show both new, old object and diff during syncs and updates
- use pretty package to pretty-print go structures
-
- Specify context in kubectl commands.
- Add a section on installing zkubectl and getting access to the DB cluster.
- Add a section on installing the service account.
Remove fixed namespace from all manifests, reduce resource requests.
Remove the storageclass default, since it is not present in minikube.
Use the team name instead of integer id, remove unused robots.
The manifests are still compatible with the non-local deployment,
the only difference is that now a namespace is requred (assuming
that the operator can only be deployed in a specific namespace.)
