JVM (Spring Boot / Scala / Kotlin)
Startup delay
Spring Boot loads the full application context before accepting HTTP. Cold starts typically take 60–120 seconds depending on the number of beans and auto-configuration classes.
livenessProbe:
tcpSocket:
port: 8080
initialDelaySeconds: 120
periodSeconds: 30
failureThreshold: 6
readinessProbe:
httpGet:
path: /actuator/health
port: 8080
initialDelaySeconds: 90
periodSeconds: 15
failureThreshold: 3
If the app exposes a Spring Actuator health endpoint, prefer it for readiness over the root path.
Heap limit
Set -Xmx to keep the heap within the container memory limit. The JVM does not automatically respect cgroup limits on older JDK versions.
env:
- name: JAVA_OPTS
value: "-Xmx512m -Xms256m"
resources:
limits:
memory: 768Mi
requests:
memory: 512Mi
Keep -Xmx 25–33% below the container limit to leave room for off-heap memory (metaspace, direct buffers, GC overhead).
Resources
512Mi–1Gi request is typical. JVM startup can spike higher — use requests to reserve and limits to cap.
