Previously, the operator started to move the pods off the nodes to be
decomissioned by watching the eol_node_label value. Every new postgres
pod has been created with the anti-affinity to that label, making sure
that the pods being moved won't land on another to be decomissioned
node.
The changes introduce another label that indicates the ready node. The
new pod affinity will esnure that the pod is only scheduled to the node
marked as ready, discarding the previous anti-affinity. That way the
nodes can transition from the pending-decomission to the other statuses
(drained, terminating) without having pods suddently scaled to them.
In addition, rename the label that triggers the start of the upgrade
process to node_eol_label (for consistency with node_readiness_label)
and set its default vvalue to lifecycle-status:pending-decomission.
- 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
removing parts of config.
* chaning secret name pattern to make things shorter.
* Move section on self building docker image.
* Fix typo.
* Bump image.
* bump version for pdb fix.
* Changes in regards to review.
* Fix xhyve driver link.
* Move to new api, remove service account, not needed for minikube.
* Changed minimal manifest and example to use right file.
* Added service account for operator again, it is needed in pods anyways later.
- Call comparison function in the case of the sync as well as for update
- Include full cluster name in PDB name
- Assign cluster labels to the PDB object
