Make flux depend unconditionally on single-replica-storageclass when longhorn is used (!7543) · Merge requests · Sylva-projects / sylva-core

What does this MR do and why?

Ensure that single-replica-storageclass is installed before flux in management cluster, in order to avoid unit timeouts as described in #3907

Since other CSI are defining their storageclass alongside with the unit, there is no need to add such dependency for other units.

In order to avoid dependency loop in preview, we change flux dependency in management cluster base-deps to only exist during upgrades. It does not change anything practically, since flux is installed from bootstrap in management cluster.

Side note:

We should also probably consider moving other dependencies on CSI and CSI units defined in bootstrap on management-cluster-flux unit:

depends_on:
  '{{ .Values._internal.default_storage_class_unit_ref }}': true
  cluster-reachable: true
  '{{ .Values._internal.cni_ready_unit }}': '{{ .Values.cluster.capi_providers.bootstrap_provider | eq "cabpk" }}'

To flux-common in values.yaml (with a condition on "not is_upgrade") to ensure proper installation of flux in workload cluster in case where it'd be enabled in this context, because we'll have the same kind of dependency as in bootstrap.

Global config for deployment pipelines

autorun pipelines
allow failure on pipelines
record sylvactl events

Notes:

Enabling autorun will make deployment pipelines to be run automatically without human interaction
Disabling allow failure will make deployment pipelines mandatory for pipeline success.
if both autorun and allow failure are disabled, deployment pipelines will need manual triggering but will be blocking the pipeline

Be aware: after configuration change, pipeline is not triggered automatically. Please run it manually (by clicking the run pipeline button in Pipelines tab) or push new code.
