MANAGEMENT_ENDPOINT_HEALTH_GROUP_READINESS_INCLUDE=readinessState,db puts the datasource into Spring Boot's readiness group, which shipped with readinessState alone: a total database outage left the pod 1/1 Ready while every request failed. Naming the members replaces the default, so readinessState is repeated. The liveness group stays untouched on purpose, because an outage has to keep traffic away rather than add a crash loop to it. MANAGEMENT_HEALTH_MAIL_ENABLED=false removes the mail indicator, which pinned the aggregate /actuator/health at 503 for the whole life of a healthy release, because the chart's mail wiring points at localhost:1025 where nothing listens. values.yaml and NOTES.txt document what that costs and when it has to be switched back on.

# Health indicators and probe groups
|
|
#
|
|
# Spring Boot creates the "liveness" and "readiness" groups by
|
|
# itself here (measured: /actuator/health answers
|
|
# {"groups":["liveness","readiness"]} with nothing configured), but
|
|
# the readiness group ships with readinessState ALONE. Without the
|
|
# line below a total database outage leaves /actuator/health/readiness
|
|
# at 200 and the pod 1/1 Ready while every request fails (#218).
|
|
# Naming the group's members REPLACES the default, so readinessState
|
|
# has to be repeated. "db" is the datasource indicator's real name,
|
|
# read off the running endpoint.
|
|

|
|
# The liveness group is deliberately NOT extended: a database
|
|
# outage has to keep traffic away, but restarting the pod does not
|
|
# bring the database back — it would only add a crash loop to the
|
|
# outage.
|
|
#
|
|
# The mail indicator is switched off because the mail wiring below
|
|
# points at localhost:1025, where nothing listens. Left on, it holds
|
|
# the aggregate /actuator/health at 503 DOWN for the whole life of a
|
|
# healthy release (#217). Anyone who later configures real mail
|
|
# delivery has to switch it back on via urlaubsverwaltung.env, or
|
|
# the endpoint stays blind to a broken mail server.
