# Helm2 to Helm3 Migration
|
|
|
|
Follow below-mentioned instructions to migrate Reloader from Helm2 to Helm3
|
|
|
|
## Instructions
|
|
|
|
There are 3 steps involved in migrating the Reloader from Helm2 to Helm3.
|
|
|
|
### Step 1
|
|
|
|
Install the `helm-2to3` plugin
|
|
|
|
```bash
|
|
helm3 plugin install https://github.com/helm/helm-2to3
|
|
|
|
helm3 2to3 convert <release-name>
|
|
|
|
helm3 2to3 cleanup --release-cleanup --skip-confirmation
|
|
```
|
|
|
|
### Step 2
|
|
|
|
Add the following Helm3 labels and annotations on Reloader resources.
|
|
|
|
Label:
|
|
|
|
```yaml
|
|
app.kubernetes.io/managed-by=Helm
|
|
```
|
|
|
|
Annotations:
|
|
|
|
```yaml
|
|
meta.helm.sh/release-name=<release-name>
|
|
meta.helm.sh/release-namespace=<namespace>
|
|
```
|
|
|
|
For example, to label and annotate the ClusterRoleBinding and ClusterRole:
|
|
|
|
```bash
|
|
KIND=ClusterRoleBinding
|
|
NAME=reloader-reloader-role-binding
|
|
RELEASE=reloader
|
|
NAMESPACE=kube-system
|
|
kubectl annotate $KIND $NAME meta.helm.sh/release-name=$RELEASE
|
|
kubectl annotate $KIND $NAME meta.helm.sh/release-namespace=$NAMESPACE
|
|
kubectl label $KIND $NAME app.kubernetes.io/managed-by=Helm
|
|
|
|
KIND=ClusterRole
|
|
NAME=reloader-reloader-role
|
|
RELEASE=reloader
|
|
NAMESPACE=kube-system
|
|
kubectl annotate $KIND $NAME meta.helm.sh/release-name=$RELEASE
|
|
kubectl annotate $KIND $NAME meta.helm.sh/release-namespace=$NAMESPACE
|
|
kubectl label $KIND $NAME app.kubernetes.io/managed-by=Helm
|
|
```
|
|
|
|
### Step 3
|
|
|
|
Upgrade to desired version
|
|
|
|
```bash
|
|
helm3 repo add stakater https://stakater.github.io/stakater-charts
|
|
|
|
helm3 repo update
|
|
|
|
helm3 upgrade <release-name> stakater/reloader --version=v0.0.72
|
|
```
