一直是Pending

根据你给出pod的描述，得出的错误如下

Warning FailedScheduling 56s (x7 over 9m45s) default-scheduler 0/6 nodes are available: 6 node(s) didn't match node selector.

即没到找到相应标签的kubernetes节点，无法生成pod

目前有两种方法可以解决你的问题

  1. 注释values.yaml文件中的affinity的整个配置信息(由于我提交的时候忘记注释)

    affinity:
nodeAffinity:
requiredDuringSchedulingIgnoredDuringExecution:
  nodeSelectorTerms:
  - matchExpressions:
    - key: "application/clickhouse"
      operator: In
      values:
      - "true"

  2. 给你的kubernetes集群的每个节点添加标签

    kubectl label node <node_name> application/clickhouse=true

好的  感谢 ，我再试试
