关于 kubernetes：配置映射不适用于 pod？


configmaps not available for a pod?

我反复看到类似的东西；

Warning FailedSync Error syncing pod, skipping: failed to
"StartContainer" for"some-service" with RunContainerError:
"GenerateRunContainerOptions: Couldn't find key app-id in ConfigMap
default/intercom"

部署尝试设置环境的位置。来自 configmap 的 vars，即：

apiVersion: v1
data:
  intercom: |
    app-id=some-id
    api-key=some-key
kind: ConfigMap
metadata:
  creationTimestamp: 2016-10-23T13:09:58Z
  name: intercom
  namespace: default

  selfLink: /api/v1/namespaces/default/configmaps/intercom
  uid: ffeea5f0-9921-11e6-b2b7-0acff65e44c3

部署如下：

                configMapKeyRef:

                  key: api-key
          ports:
            - containerPort: 9000
      imagePullSecrets:

这里有什么问题？

你的 configmap 只包含一个键：intercom

您可以将配置映射用于环境变量，因为这样
config.yaml

apiVersion: v1
