You can specify an environment variable DEBUG 1/0 to enable/disable
debug mode. Debug mode assumes delve dependency for remote debugging,
and debugging symbols for go build.
Previously, it was set to the lifecycle-status:ready, breaking a
lot of minikube deployments. Also it was not possible befor to run
with this label set to an empty value.
Document the effect of the label in the new section of the
documentation.
Avoid migrating replica pods, since they will be handled by the
node draining anyway (the PDB specifies that only masters are to
be kept).
Allow migration of the single-pod clusters.
* Trigger the node migration on the lack of the readiness label.
* Examine the node's readiness status on node add.
Make sure we don't miss the not ready node, especially when the
operator is killed during the migration.
Introduce a new lock called specMu lock to protect the cluster spec.
This lock is held on update and sync, and when retrieving the spec in
the API code. There is no need to acquire it for cluster creation and
deletion: creation assigns the spec to the cluster before linking it to
the controller, and deletion just removes the cluster from the list in
the controller, both holding the global clustersMu Lock.
* Scalyr agent sidecar for log shipping
* Remove the default for the Scalyr image
Now the image needs to be specified explicitly to enable log shipping to
Scalyr. This removes the problem of having to generate the config file
or publish our agent image repository.
* Add configuration variable for Scalyr server URL
Defaults to the EU address.
* Alter style
Newlines are cheap and make code easier to edit/refactor, but ok.
* Fix StatefulSet comparison logic
I broke it when I made the comparison consider all containers in the
PostgreSQL pod.
* Make sure the statefulset that is deleted manually gets re-created.
Per report and analysis by Manuel Gomez.
* Move the existence checks for other objects out of the Create functions.
create{Object} for services, endpoints and PDBs refused to continue if
there is a cached definition in the cluster, however, the only place
where it makes sense is when creating a new cluster. Note that contrary
to the statefulset this doesn't fix any issues, since those definitions
were nullified correspondingly when the sync code detected there is no
object present in the Kubernetes cluster.
