Real bug affecting both home and VPS GitLab, found live diagnosing why
VPS's webservice pod was stuck at Init:0/3 for 74+ minutes (surfacing as
404s - nothing was ever actually serving):
global.appConfig.omniauth.providers: [{secret: gitlab-oidc-secret, key:
provider}] requires that secret to have a 'provider' key (a full YAML
omniauth provider config) - gitlab-oidc-secret never has one, only
GITLAB_OIDC_CLIENT_ID/SECRET, which get consumed via extraEnvFrom +
GITLAB_OMNIBUS_CONFIG's gitlab_rails['omniauth_providers'] instead (the
actual, complete mechanism already configuring OIDC - this providers:
list was always redundant). Removed it from both values.yaml files.
Home's GitLab has run fine so far because Kubernetes doesn't re-validate
already-mounted volumes when a referenced Secret's shape changes -
webservice/sidekiq there just haven't restarted since gitlab-oidc-secret
was last (if ever) in a shape with that key. VPS's identical values
shape hit it immediately on first pod creation. This was a live landmine
for home too - fixed before it could bite on a future restart.
Also: global.kas.enabled: false added to the VPS values (gitlab.kas.enabled
alone doesn't stop KAS pods - found live, separate toggle).

|
|
# deployment, which shares this same values shape) that the chart
|
|
# requires that secret to actually HAVE a `provider` key (a full
|
|
# omniauth provider config block, YAML-encoded) when this list is
|
|
# set, and gitlab-oidc-secret never had one - it only has
|
|
# GITLAB_OIDC_CLIENT_ID/SECRET, consumed via extraEnvFrom below and

# gitlab.webservice.extraEnv's GITLAB_OMNIBUS_CONFIG instead, which
|
|
# is the ACTUAL mechanism configuring the OIDC provider (this
|
|
# global.appConfig.omniauth.providers list was always redundant/
|
|
# unused for our setup). Silently didn't matter here at home because
|
|
# this Deployment hasn't restarted since gitlab-oidc-secret was last
|
|
# in whatever shape included that key (if it ever did) - Kubernetes
|
|
# doesn't re-validate already-mounted volumes when a Secret's shape
|
|
# changes, only NEW pod creation does, which is exactly why the VPS
|
|
# deployment (fresh pods, same values shape) hit it immediately
|
|
# ("FailedMount: references non-existent secret key: provider") while
|
|
# this one didn't - until its next restart.
