此时,在集群配置页面中,可能会同时看到集群名称后有异常提示,提示信息为“业务集群已经被删除,请配置新的业务集群”,或者也可能会看到集群配置页面中未配置集群,集群已被自动移除。

问题原因

当前承载流水线运行的Kubernetes集群已被删除,无法正常连接。

解决方案

方案一:直接更改Kubernetes集群

  1. (可选)移除旧集群。

    当已删除集群未在集群配置页面被自动移除时,请执行以下操作移除该旧集群。反之,可跳过本步骤。

    在云平台的顶部导航栏中,依次选择[产品与服务]-[DevOps]-[集群配置],进入“集群配置”页面。在该页面中,单击列表上方的 移除 ,弹出“移除集群”提示框。在该提示框中,单击 移除 ,移除该旧集群,并关闭提示框。

  2. 添加新集群。

    在云平台的顶部导航栏中,依次选择[产品与服务]-[DevOps]-[集群配置],进入“集群配置”页面。在该页面中,单击页面上方的 添加集群 ,弹出“添加集群”对话框。在该对话框中,选择用于承载流水线运行的新集群后,单击 添加 ,开始添加Kubernetes集群,并关闭对话框。

方案二:重新配置该Kubernetes集群

配置Kubernetes集群的具体操作步骤,请参考 配置集群

当上述Kubernetes集群配置成功且状态为“健康”状态时,DevOps功能会自动恢复正常,可以直接按需重新执行上述流水线。
