Pod Spec

Artifact Hub

The chart supports several top-level values that map directly to Kubernetes Pod spec fields.

Use these fields when you need Kubernetes-native Pod behavior that is not covered by a more specific chart option.

Object and Array Fields​

The following values are rendered directly into the Pod spec:

nodeSelector: {}
nodeName: ""
affinity: {}
tolerations: []
dnsConfig: {}
hostAliases: []
overhead: {}
readinessGates: []
securityContext: {}
topologySpreadConstraints: []
ephemeralContainers: []

Scalar Fields​

The following optional values are rendered when set:

activeDeadlineSeconds: 100
automountServiceAccountToken: true
dnsPolicy: ClusterFirst
enableServiceLinks: true
hostIPC: false
hostNetwork: false
hostPID: false
hostname: app
preemptionPolicy: PreemptLowerPriority
priority: 0
priorityClassName: high-priority
restartPolicy: Always
runtimeClassName: gvisor
schedulerName: default-scheduler
serviceAccountName: app-service-account
setHostnameAsFQDN: false
shareProcessNamespace: false
subdomain: app
note

serviceaccount.name takes precedence over serviceAccountName when both values are set.

restartPolicy​

For Jobs and CronJobs, the chart renders restartPolicy: OnFailure when restartPolicy is not explicitly set.

Example: Set Pod Security Context​

containers:
- image: john/appbackend
securityContext:
  runAsNonRoot: true
  runAsUser: 1000
  fsGroup: 1000

Example: Set Topology Spread Constraints​

containers:
- image: john/appbackend
topologySpreadConstraints:
- maxSkew: 1
  topologyKey: topology.kubernetes.io/zone
  whenUnsatisfiable: ScheduleAnyway
  labelSelector:
    matchLabels:
      app.kubernetes.io/name: devspace-app
