安装（进阶）

带着证书管理器安装 KubeVela​

KubeVela 可以使用证书管理器为你的应用生成证书，但是你需要提前安装好证书管理器。

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

安装 KubeVela 同时启用证书管理器：

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

安装预发布版​

在使用 helm search 命令时，添加标记参数 --devel 即可搜索出预发布版。预发布版的版本号格式为 <next_version>-rc-master，例如 0.4.0-rc-master，代表的是一个基于 master 分支构建的发布候选版。

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

然后尝试跟着以下的命令安装一个预发布版。

helm install --create-namespace -n vela-system kubevela kubevela/vela-core --version <next_version>-rc-master
NAME: kubevela
LAST DEPLOYED: Thu Apr  1 19:41:30 2021
NAMESPACE: vela-system
STATUS: deployed
REVISION: 1
NOTES:
Welcome to use the KubeVela! Enjoy your shipping application journey!

升级​

第一步 更新 Helm 仓库​

通过以下命令获取 KubeVela 最新发布的 chart：

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

第二步 升级 KubeVela 的 CRDs​

kubectl apply -f https://raw.githubusercontent.com/kubevela/kubevela/release-1.0/charts/vela-core/crds/core.oam.dev_componentdefinitions.yaml
kubectl apply -f https://raw.githubusercontent.com/kubevela/kubevela/release-1.0/charts/vela-core/crds/core.oam.dev_workloaddefinitions.yaml
kubectl apply -f https://raw.githubusercontent.com/kubevela/kubevela/release-1.0/charts/vela-core/crds/core.oam.dev_traitdefinitions.yaml
kubectl apply -f https://raw.githubusercontent.com/kubevela/kubevela/release-1.0/charts/vela-core/crds/core.oam.dev_applications.yaml
kubectl apply -f https://raw.githubusercontent.com/kubevela/kubevela/release-1.0/charts/vela-core/crds/core.oam.dev_approllouts.yaml
kubectl apply -f https://raw.githubusercontent.com/kubevela/kubevela/release-1.0/charts/vela-core/crds/core.oam.dev_applicationrevisions.yaml
kubectl apply -f https://raw.githubusercontent.com/kubevela/kubevela/release-1.0/charts/vela-core/crds/core.oam.dev_scopedefinitions.yaml
kubectl apply -f https://raw.githubusercontent.com/kubevela/kubevela/release-1.0/charts/vela-core/crds/core.oam.dev_appdeployments.yaml
kubectl apply -f https://raw.githubusercontent.com/kubevela/kubevela/release-1.0/charts/vela-core/crds/core.oam.dev_applicationcontexts.yaml
kubectl apply -f https://raw.githubusercontent.com/kubevela/kubevela/release-1.0/charts/vela-core/crds/core.oam.dev_definitionrevisions.yaml

提示：如果看到诸如 * is invalid: spec.scope: Invalid value: "Namespaced": filed is immutable 之类的错误，请删除出错的 CRD 后再重新安装。

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

第三步 升级 KubeVela Helm chart​

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

卸载​

运行命令:

helm uninstall -n vela-system kubevela
rm -r ~/.vela

命令会卸载 KubeVela 服务和相关的依赖组件，同时会清理本地 CLI 的缓存
然后清理 CRDs（默认情况下，helm 不会移除 CRDs）

 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 \
  definitionrevisions.core.oam.dev
