Deployment order
Helm collects all of the resources in a given Chart and its dependencies, groups them by resource type, and then installs them in the following order (as shown here):
- Namespace
- ResourceQuota
- LimitRange
- PodSecurityPolicy
- Secret
- ConfigMap
- StorageClass
- PersistentVolume
- PersistentVolumeClaim
- ServiceAccount
- CustomResourceDefinition
- ClusterRole
- ClusterRoleBinding
- Role
- RoleBinding
- Service
- DaemonSet
- Pod
- ReplicationController
- ReplicaSet
- Deployment
- StatefulSet
- Job
- CronJob
- Ingress
- APIService
During uninstallation of a release, the order is reversed (as shown here).
