- fix the lack of closing the cursor for the query that returned no
rows.
- fix syncing of the user options, as previously those were not
fetched from the database.
- search_path accepts a list of values that cannot be quoted, as
quoting would make PostgreSQL interpret the result as a single
value. Since we require quoting of values with commas in the
operator's configMap in order to avoid confusing them with the
separate map entities, we need to strip those quotes before
passing the value to PostgreSQL.
- make ftm run
A value in a configMap that is a map itself
(a key:value string separated by commas) may include commans inside
quotes (i.e. search_path:"public,"$user"). The changes make marshaling
code process such cases correctly.
Add options to the PgUser structure, potentially allowing to set
per-role options in the cluster definition as well.
Introduce api_roles_configuration operator option with the default
of log_statement=all
* Add node toleration config to PodSpec
This allows to taint nodes dedicated to Postgres and prevents other pods from running on these nodes.
* Document taint and toleration setup
And remove setting from default operator ConfigMap
* Allow to overwrite tolerations with Postgres manifest
Be more rigorous about validating user flags.
Only accept CREATE ROLE flags that doesn't have any params (i.e.
not ADMIN or CONNECTION LIMIT). Check that both flag and NOflag
are not used at the same time.
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
- 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.
* Deny all requests to the load balancer by default.
* Operator-wide toggle for the load-balancer.
* Define per-cluster useLoadBalancer option.
If useLoadBalancer is not set - then operator-wide defaults take place. If it
is true - the load balancer is created, otherwise a service type clusterIP is
created.
Internally, we have to completely replace the service if the service type
changes. We cannot patch, since some fields from the old service that will
remain after patch are incompatible with the new one, and handling them
explicitly when updating the service is ugly and error-prone. We cannot
update the service because of the immutable fields, that leaves us the only
option of deleting the old service and creating the new one. Unfortunately,
there is still an issue of unnecessary removal of endpoints associated with
the service, it will be addressed in future commits.
* Revert the unintended effect of go fmt
* Recreate endpoints on service update.
When the service type is changed, the service is deleted and then
the one with the new type is created. Unfortnately, endpoints are
deleted as well. Re-create them afterwards, preserving the original
addresses stored in them.
* Improve error messages and comments. Use generate instead of gen in names.
