* Up until now, the operator read its own configuration from the
configmap. That has a number of limitations, i.e. when the
configuration value is not a scalar, but a map or a list. We use a
custom code based on github.com/kelseyhightower/envconfig to decode
non-scalar values out of plain text keys, but that breaks when the data
inside the keys contains both YAML-special elememtns (i.e. commas) and
complex quotes, one good example for that is search_path inside
`team_api_role_configuration`. In addition, reliance on the configmap
forced a flag structure on the configuration, making it hard to write
and to read (see
https://github.com/zalando-incubator/postgres-operator/pull/308#issuecomment-395131778).
The changes allow to supply the operator configuration in a proper YAML
file. That required registering a custom CRD to support the operator
configuration and provide an example at
manifests/postgresql-operator-default-configuration.yaml. At the moment,
both old configmap and the new CRD configuration is supported, so no
compatibility issues, however, in the future I'd like to deprecate the
configmap-based configuration altogether. Contrary to the
configmap-based configuration, the CRD one doesn't embed defaults into
the operator code, however, one can use the
manifests/postgresql-operator-default-configuration.yaml as a starting
point in order to build a custom configuration.
Since previously `ReadyWaitInterval` and `ReadyWaitTimeout` parameters
used to create the CRD were taken from the operator configuration, which
is not possible if the configuration itself is stored in the CRD object,
I've added the ability to specify them as environment variables
`CRD_READY_WAIT_INTERVAL` and `CRD_READY_WAIT_TIMEOUT` respectively.
Per review by @zerg-junior and @Jan-M.
* 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.
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.

* 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.
introduce Pod events channel;
add parsing of the MaintenanceWindows section;
skip deleting Etcd key on cluster delete;
use external etcd host;
watch for tpr/pods in the namespace of the operator pod only;
