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.

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:

helm install --create-namespace -n vela-system --set admissionWebhooks.certManager.enabled=true kubevela kubevela/vela-core

Upgrade#

Step 1. Update Helm repo#

You can explore the newly released chart versions of KubeVela by run:

helm repo update
helm search repo kubevela/vela-core -l

Step 2. Upgrade KubeVela CRDs#

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.

kubectl delete crd \
scopedefinitions.core.oam.dev \
traitdefinitions.core.oam.dev \
workloaddefinitions.core.oam.dev

Step 3. Upgrade KubeVela Helm chart#

helm upgrade --install --create-namespace --namespace vela-system kubevela kubevela/vela-core --version <the_new_version>

Clean Up#

Run:

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):

kubectl delete crd \
appdeployments.core.oam.dev \
applicationconfigurations.core.oam.dev \
applicationcontexts.core.oam.dev \
applicationrevisions.core.oam.dev \
applications.core.oam.dev \
approllouts.core.oam.dev \
componentdefinitions.core.oam.dev \
components.core.oam.dev \
containerizedworkloads.core.oam.dev \
healthscopes.core.oam.dev \
manualscalertraits.core.oam.dev \
podspecworkloads.standard.oam.dev \
scopedefinitions.core.oam.dev \
traitdefinitions.core.oam.dev \
workloaddefinitions.core.oam.dev
