Helm install in certain order
Helm collects all of the resources in a given Chart and it's dependencies, groups them by resource type, and then installs them in the following order (see here - Helm 2.10):
- 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 (see here).
Following this logic, in your case when your Job resource is created, both the Secret and the ConfigMap will already be applied, but Helm won't wait for the Job to complete before applying the Deployment. If you split your Chart to two parts (1-4, 5) and install them sequentially you would still have the problem of the Deployment being possibly applied before the Job is completed. What I would suggest is splitting your Chart to two parts (1-3, 4-5), in which the the Job has a pre-install hook, which would make sure it completes before your Deployment is applied.
Here's the order for Helm 3.7 (latest as of this writing):
- Namespace
- NetworkPolicy
- ResourceQuota
- LimitRange
- PodSecurityPolicy
- PodDisruptionBudget
- ServiceAccount
- Secret
- SecretList
- ConfigMap
- StorageClass
- PersistentVolume
- PersistentVolumeClaim
- CustomResourceDefinition
- ClusterRole
- ClusterRoleList
- ClusterRoleBinding
- ClusterRoleBindingList
- Role
- RoleList
- RoleBinding
- RoleBindingList
- Service
- DaemonSet
- Pod
- ReplicationController
- ReplicaSet
- Deployment
- HorizontalPodAutoscaler
- StatefulSet
- Job
- CronJob
- Ingress
- APIService
Source. Only difference from above is more resource types and the ServiceAccount got pushed up slightly in the list.
Also, according to this closed git issue, CustomResources are last to be installed, after everything listed above.
Also note that if you want to change this order and create a certain resource before everything else, you can do so with chart hooks
