Container Apps Health Probes

Always configure health probes for production workloads.

Liveness Probe

Detects if container is alive. Failure triggers restart.

probes: [
  \{
    type: 'liveness'
    httpGet: \{
      path: '/health'
      port: 8080
    \}
    initialDelaySeconds: 10
    periodSeconds: 30
    failureThreshold: 3
  \}
]

Readiness Probe

Detects if container is ready to receive traffic.

probes: [
  \{
    type: 'readiness'
    httpGet: \{
      path: '/ready'
      port: 8080
    \}
    initialDelaySeconds: 5
    periodSeconds: 10
    failureThreshold: 3
  \}
]

Startup Probe

For slow-starting containers. Delays other probes until startup succeeds.

probes: [
  \{
    type: 'startup'
    httpGet: \{
      path: '/health'
      port: 8080
    \}
    initialDelaySeconds: 0
    periodSeconds: 10
    failureThreshold: 30  // 30 * 10s = 5 min max startup
  \}
]

Recommendations

Probe	Path	Initial Delay	Period
Liveness	/health	10s	30s
Readiness	/ready	5s	10s
Startup	/health	0s	10s
