This operator's own Deployment template crash-looped a few times against a from-scratch postgres-operator cluster still doing initdb and Patroni leader election -- exactly the gap examples/demo's own README just documented for it. terdut-server's ping-retry budget on startup (internal/db/db.go in that repo) is sized for a much shorter, different race (NetworkPolicy propagation, a few seconds), not genuine first-time cluster creation, so it exhausted and the process exited before ever binding its HTTP port -- a startupProbe cannot fix that, since the crash happens before there is anything to probe. Same root cause and same fix as charts/terdut-server's own deployment.yaml template as of that repo's v0.33.2. waitForPostgresContainer reuses dbEnv unchanged: both of resolveDatabaseEnv's two paths (DSN, postgresClusterRef) put TERDUT_DB_DSN first, so it's already exactly what pg_isready needs, and pg_isready needs no credentials, so dbEnv's optional PGPASSWORD riding along too is harmless rather than load-bearing. Covered by the existing envtest suite (asserts on Containers[0], the main container, unaffected by adding InitContainers) -- `make test` passes unchanged, 71.7% coverage on internal/controller. Updates examples/demo's own README, which no longer needs to warn about this.
Terdut operator
Aims to expose most config as CRD's, so end users can self-service over gitops.
See DESIGN.md for the full design: CRD catalog and specs,
reconciliation semantics, bootstrap/auth, Postgres integration, RBAC, and the
relationship to charts/terdut-server. This README stays a short pitch; the
open questions it used to carry are now resolved decisions there (§2).
CRD's
terdutServers
Creates a server — Deployment, Service, database wiring, bootstrap, operator
credentials, and allowedTeams consent for cross-namespace teams. See
DESIGN.md §4.1, §4.6.
terdutTeams
- team name
- oidc groups
serverRef— explicit reference to itsTerdutServer, may be in a different namespace (one team owns the server, others self-service a team against it), gated by thatTerdutServer's ownallowedTeamsfield (DESIGN.md §2, §4.1, §4.2, §4.6)
terdutEscalationrules
- rule
teamRef— explicit reference to itsTerdutTeam(DESIGN.md §2, §4.3)
terdutDeadmansswitches
- rule
teamRef(DESIGN.md §4.4)
terdutAlertSources
teamRef(DESIGN.md §4.5)- URL/key are generated by the server at creation and surfaced only via a generated Secret, never set explicitly
Demo
examples/demo wires one of every CRD above together
— two teams, each with an escalation rule, a dead man's switch and an
alert source — plus a script that fires synthetic Alertmanager webhooks
at it, so you can watch real incidents open, escalate and resolve without
a real Alertmanager anywhere in the picture.
