# k8s/temporal/temporal-values.yaml

# Temporal — workflow engine
|
|
# Uses external CNPG PostgreSQL for persistence (temporal-db)
|
|
# Visibility via same PostgreSQL instance, separate database.
|
|
#
|
|
# IMPORTANT — chart schema note (root-caused after Postgres never actually
|
|
# taking effect despite looking configured):
|
|
# We're pinned to temporalio/helm-charts @ 0.74.0 (see targetRevision in
|
|
# k8s/argocd/apps/60-applications.yaml), which uses the OLD flat persistence
|
|
# schema:
|
|
# server.config.persistence.<default|visibility>.driver: "sql"|"cassandra"
|
|
# server.config.persistence.<default|visibility>.sql: {...}
|
|
# NOT the newer `datastores:`-wrapped schema
|
|
# (server.config.persistence.datastores.<store>.sql) shown in the current
|
|
# chart's values/values.postgresql.yaml example - that key was introduced in
|
|
# a later major version and doesn't exist in 0.74.0. Helm doesn't validate
|
|
# unknown keys, so a `datastores:` block here is silently a no-op: Temporal
|
|
# would keep defaulting to Cassandra (with empty hosts: []) regardless of
|
|
# anything nested inside it. Verified via `helm template` against the actual
|
|
# 0.74.0 chart before writing this file - see chat history for the
|
|
# side-by-side proof (rendered manifest showed CASSANDRA_HOST env vars and
|
|
# temporal-cassandra-tool commands using the old datastores:-based values).
|
|
#
|
|
# Likewise `schema.setup.enabled` / `schema.update.enabled` /
|
|
# `schema.createDatabase.enabled` are the real toggles for the schema-setup
|
|
# Job (all default true) - there is no `jobs.autoSetup` key in this chart.
