* Allow configuring pod priority globally and per cluster.
Allow to specify pod priority class for all pods managed by the operator,
as well as for those belonging to individual clusters.
Controlled by the pod_priority_class_name operator configuration
parameter and the podPriorityClassName manifest option.
See https://kubernetes.io/docs/concepts/configuration/pod-priority-preemption/#priorityclass
for the explanation on how to define priority classes since Kubernetes 1.8.
Some import order changes are due to go fmt.
Removal of OrphanDependents deprecated field.
Code review by @zerg-junior
There are shortcuts in this code, i.e. we created the deepcopy function
by using the deepcopy package instead of the generated code, that will
be addressed once migrated to client-go v8. Also, some objects,
particularly statefulsets, are still taken from v1beta, this will also
be addressed in further commits once the changes are stabilized.
Enhance definitions of infrastructure roles by allowing membership in multiple roles, role options and per-role configuration to be specified in the infrastructure role configmap, which must have the same name as the infrastructure role secret. See manifests/infrastructure-roles-configmap.yaml for the examples and updated README for the description of different types of database roles supposed by the operator and their purposes.
Change the logic of merging infrastructure roles with the manifest roles when they have the same name, to return the infrastructure role unchanged instead of merging. Previously, we used to propagate flags from the manifest role to the resulting infrastructure one, as there were no way to define flags for the infrastructure role; however, this is not the case anymore.
Code review and tests by @erthalion
* Track origin of roles.
* Propagate changes on infrastructure roles to corresponding secrets.
When the password in the infrastructure role is updated, re-generate the
secret for that role.
Previously, the password for an infrastructure role was always fetched from
the secret, making any updates to such role a no-op after the corresponding
secret had been generated.
* 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
- Avoid relying on Clientset structure to call Kubernetes API functions.
While Clientset is a convinient "catch-all" abstraction for calling
REST API related to different Kubernetes objects, it's impossible to
mock. Replacing it wih the kubernetes.Interface would be quite
straightforward, but would require an exra level of mocked interfaces,
because of the versioning. Instead, a new interface is defined, which
contains only the objects we need of the pre-defined versions.
- Move KubernetesClient to k8sutil package.
- Add more tests.
