charts

Prerequisites

• Kubernetes 1.17+
• Helm 3.5.4

Install Helm

Helm is a tool for managing Kubernetes charts. Charts are packages of pre-configured Kubernetes resources.

To install Helm, refer to the Helm install guide and ensure that the helm binary is in the PATH of your shell.

Using Helm

Once you have installed the Helm client, you can deploy a Helm Chart into a Kubernetes cluster.

Please refer to the Quick Start guide if you wish to get running in just a few commands, otherwise the Using Helm Guide provides detailed instructions on how to use the Helm client to manage packages on your Kubernetes cluster.

Useful Helm Client Commands:

• Install a chart: helm install test-chain cita-cloud-local-cluster
• List your application: helm list
• Uninstall a chart: helm unintall test-chain

charts's Issues

local-pvc does not work properly with cephfs

What happened?

通过 Helm charts 部署 6.4.0 版本的 CITA Cloud 时，四个节点仅有一个能够成功运行，其他三个节点出现类似如下错误：

What did you expect to happen?

节点能够成功运行，不会出现该错误。

How can we reproduce it?

PVC 使用 Rook Ceph 提供的 CephFS 存储类，然后运行 CITA Cloud

helm install local-pvc cita-cloud/cita-cloud-pvc     \
   --set scName=ceph-filesystem                 \
   --set size=1000Gi

$ helm install test-chain cita-cloud/cita-cloud-local-cluster  \
   --set pvcName=local-pvc                                     \
   --set service.nodePort=32224                                \
   --set service.vmPort=32225                                  \
   --set config.superAdmin=0xc8ca9cc77a7f822fdd0baef7a7740f9dba493455

Anything else we need to know?

现在，如果使用 NFS 存储，则不存在该问题，原因是 PV PVC 的 accessModes 非强制属性，NFS 及其他某些存储没有实现强制限制。

而 Ceph 的 CephFS StorageClass 则进行强制限制，导致该 PV PVC 无法在其他节点使用。

将 cita-cloud-pvc 的 accessModes: ["ReadWriteOnce"] 修改成 ReadWriteMany 即可解决问题。

Chart工程支持6.3.2

给pod增加lable

使用chaosmesh做可靠性测试的时候，需要使用lable来选择要测试的pod。
但是目前没有增加自己的lable，依赖helm自行添加的lable。
与operator添加的lable不一致。

通过自行添加lable，不管用何种方式启动的链，lable保持一致。
