-
- 更新配置
- helm upgrade
指定软件名指定本地压缩文件--namespace指定命名空间-
[root@k8s-master ~]# helm upgrade kafka-19-1-5 ./kafka-19.1.5.tgz --namespace kafka-ns
-
- helm upgrade
- 卸载
- helm uninstall
指定软件名--namespace指定命名空间-
[root@k8s-master ~]# helm uninstall kafka-19-1-5 --namespace kafka-ns
-

第二种 提取yaml文件安装
- helm template
指定软件名指定本地压缩包--namespace指定命名空间--set传入需要的各种参数-
## 将压缩包下载到本地 [root@k8s-master ~]# helm pull bitnami/kafka --version 19.1.5 ## 提取 [root@k8s-master ~]# helm template kafka-19-1-5 ./kafka-19.1.5.tgz --output-dir . \ --namespace kafka-ns \ --set replicaCount=3 \ --set global.storageClass='rook-ceph-block' \ --set persistence.storageClass='rook-ceph-block' # 启动执行 [root@k8s-master ~]# kubectl apply -R -f ./kafka
-
