## Prerequisites
|
||||
|
||||
- Latest [Dapr CLI]({{< ref install-dapr-cli.md >}})
|
||||
|
||||
## Upgrade existing cluster running 0.11.x
|
||||
|
||||
1. Run these two commands to prevent `helm upgrade` from uninstalling `0.11.x` placement service:
|
||||
|
||||
```bash
|
||||
kubectl annotate deployment dapr-placement helm.sh/resource-policy=keep -n dapr-system
|
||||
```
|
||||
```bash
|
||||
kubectl annotate svc dapr-placement helm.sh/resource-policy=keep -n dapr-system
|
||||
```
|
||||
|
||||
1. Export certificates:
|
||||
|
||||
```bash
|
||||
dapr mtls export -o ./certs
|
||||
```
|
||||
|
||||
1. Upgrade Dapr to 1.0.0-rc.2:
|
||||
|
||||
```bash
|
||||
helm repo update
|
||||
```
|
||||
```bash
|
||||
helm upgrade dapr dapr/dapr --version 1.0.0-rc.2 --namespace dapr-system --reset-values --set-file dapr_sentry.tls.root.certPEM=./certs/ca.crt --set-file dapr_sentry.tls.issuer.certPEM=./certs/issuer.crt --set-file dapr_sentry.tls.issuer.keyPEM=./certs/issuer.key --set global.ha.enabled=true --wait
|
||||
```
|
||||
|
||||
1. Upgrade CRDs:
|
||||
|
||||
```bash
|
||||
kubectl replace -f https://raw.githubusercontent.com/dapr/dapr/21636a9237f2dcecd9c80f329e99b512e8377739/charts/dapr/crds/configuration.yaml
|
||||
```
|
||||
```bash
|
||||
kubectl replace -f https://raw.githubusercontent.com/dapr/dapr/21636a9237f2dcecd9c80f329e99b512e8377739/charts/dapr/crds/components.yaml
|
||||
```
|
||||
|
||||
1. Ensure 0.11.x dapr-placement service is still running and wait until all pods are running:
|
||||
|
||||
```bash
|
||||
kubectl get pods -n dapr-system -w
|
||||
|
||||
NAME READY STATUS RESTARTS AGE

||||

|
||||

|
||||
dapr-sentry-84565c747b-ldnsf 1/1 Running 0 29s
|
||||

|
||||
dapr-sidecar-injector-68f868668f-j7jcq 1/1 Running 0 29s
|
||||
dapr-sidecar-injector-68f868668f-ltxq4 1/1 Running 0 36s
|
||||
```
|
||||
|
||||
1. Restart your application deployments to update the Dapr runtime.
|
||||
|
||||
```bash
|
||||
kubectl rollout restart deploy/<DEPLOYMENT-NAME>
|
||||
```
|
||||
|
||||
1. Once the deployment is completed, delete the 0.11.x dapr-placement service:
|
||||
|
||||
```bash
|
||||
kubectl delete deployment dapr-placement -n dapr-system
|
||||
```
|
||||
|
||||
```bash
|
||||
kubectl delete svc dapr-placement -n dapr-system
|
||||
```
|
||||
|
||||
1. All done!
|
||||

||||
