Run operations concerning multiple clusters in parallel. Each cluster gets its
own worker in order to create, update, sync or delete clusters. Each worker
acquires the lock on a cluster. Subsequent operations on the same cluster
have to wait until the current one finishes. There is a pool of parallel
workers, configurable with the `workers` parameter in the configmap and set by
default to 4. The cluster-related tasks are assigned to the workers based on
a cluster name: the tasks for the same cluster will be always assigned to the
same worker. There is no blocking between workers, although there is a chance
that a single worker will become a bottleneck if too many clusters are
assigned to it; therefore, for large-scale deployments it might be necessary
to bump up workers from the default value.
* 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.
- 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
-
Previously, the controller fetched the Oauth token once at start, so eventually the token would expire and the operator could not create new users. This commit makes the operator fetch the token before each call to the Teams API.
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;
