## Install KubeVela with cert-manager
|
|
|
|
KubeVela can use cert-manager generate certs for your application if it's available. Note that you need to install cert-manager **before** the KubeVela chart.
|
|
|
|
```shell script
|
|
helm repo add jetstack https://charts.jetstack.io
|
|
helm repo update
|
|
helm install cert-manager jetstack/cert-manager --namespace cert-manager --version v1.2.0 --create-namespace --set installCRDs=true
|
|
```
|
|
|
|
Install kubevela with enabled certmanager:
|
|
```shell script
|
|
helm install --create-namespace -n vela-system --set admissionWebhooks.certManager.enabled=true kubevela kubevela/vela-core
|
|
```
|
|
|
|
## Install Pre-release
|
|
|
|
Add flag `--devel` in command `helm search` to choose a pre-release
|
|
version in format `<next_version>-rc-master`. It means a release candidate version build on `master` branch,
|
|
such as `0.4.0-rc-master`.
|
|
|
|
```shell script
|
|
helm search repo kubevela/vela-core -l --devel
|
|
```
|
|
```console
|
|
NAME CHART VERSION APP VERSION DESCRIPTION
|
|
kubevela/vela-core 0.4.0-rc-master 0.4.0-rc-master A Helm chart for KubeVela core
|
|
kubevela/vela-core 0.3.2 0.3.2 A Helm chart for KubeVela core
|
|
kubevela/vela-core 0.3.1 0.3.1 A Helm chart for KubeVela core
|
|
```
|
|
|
|
And try the following command to install it.
|
|
|
|
```shell script
|
|
helm install --create-namespace -n vela-system kubevela kubevela/vela-core --version <next_version>-rc-master
|
|
```
|
|
```console
|
|

|
## Upgrade
|
|
|
|
### Step 1. Update Helm repo
|
|
|
|
|
|
You can explore the newly released chart versions of KubeVela by run:
|
|
|
|
```shell
|
|
helm repo update
|
|
helm search repo kubevela/vela-core -l
|
|
```
|
|
|
|
### Step 2. Upgrade KubeVela CRDs
|
|
|
|
```shell
|
|
kubectl apply -f https://raw.githubusercontent.com/oam-dev/kubevela/master/charts/vela-core/crds/core.oam.dev_componentdefinitions.yaml
|
|
kubectl apply -f https://raw.githubusercontent.com/oam-dev/kubevela/master/charts/vela-core/crds/core.oam.dev_workloaddefinitions.yaml
|
|
kubectl apply -f https://raw.githubusercontent.com/oam-dev/kubevela/master/charts/vela-core/crds/core.oam.dev_traitdefinitions.yaml
|
|
kubectl apply -f https://raw.githubusercontent.com/oam-dev/kubevela/master/charts/vela-core/crds/core.oam.dev_applications.yaml
|
|
kubectl apply -f https://raw.githubusercontent.com/oam-dev/kubevela/master/charts/vela-core/crds/core.oam.dev_approllouts.yaml
|
|
kubectl apply -f https://raw.githubusercontent.com/oam-dev/kubevela/master/charts/vela-core/crds/core.oam.dev_applicationrevisions.yaml
|
|
kubectl apply -f https://raw.githubusercontent.com/oam-dev/kubevela/master/charts/vela-core/crds/core.oam.dev_scopedefinitions.yaml
|
|
kubectl apply -f https://raw.githubusercontent.com/oam-dev/kubevela/master/charts/vela-core/crds/core.oam.dev_appdeployments.yaml
|
|
kubectl apply -f https://raw.githubusercontent.com/oam-dev/kubevela/master/charts/vela-core/crds/core.oam.dev_applicationcontexts.yaml
|
|
```
|
|
|
|
> Tips: If you see errors like `* is invalid: spec.scope: Invalid value: "Namespaced": filed is immutable`. Please delete the CRD which reports error and re-apply the kubevela crds.
|
|
|
|
```shell
|
|
kubectl delete crd \
|
|
scopedefinitions.core.oam.dev \
|
|
traitdefinitions.core.oam.dev \
|
|
workloaddefinitions.core.oam.dev
|
|
```
|
|
|
|
### Step 3. Upgrade KubeVela Helm chart
|
|
|
|
```shell
|
|
helm upgrade --install --create-namespace --namespace vela-system kubevela kubevela/vela-core --version <the_new_version>
|
|
```
|
|
|
|
## Clean Up
|
|
|
|
Run:
|
|
|
|
```shell script
|
|
helm uninstall -n vela-system kubevela
|
|
rm -r ~/.vela
|
|
```
|
|
|
|
This will uninstall KubeVela server component and its dependency components.
|
|
This also cleans up local CLI cache.
|
|
|
|
Then clean up CRDs (CRDs are not removed via helm by default):
|
|
|
|
```shell script
|
|
kubectl delete crd \
|
|
appdeployments.core.oam.dev \
|
|
applicationconfigurations.core.oam.dev \
|
|
applicationcontexts.core.oam.dev \
|
|
