nginx - 将 nginx.conf 添加到 Kubernetes 集群

Question

我怎样才能通过 nginx.conf配置文件到在 Kubernetes 集群中运行的 nginx 实例？

Answer 1

您可以创建一个 ConfigMap 对象，然后将值作为文件挂载到您需要的位置:

apiVersion: v1
kind: ConfigMap
metadata:
  name: nginx-config
data:
  nginx.conf: |
    your config
    comes here
    like this
  other.conf: |
    second file
    contents

在你的 pods 规范中:

spec:
  containers:
    - name: nginx
      image: nginx
      volumeMounts:
        - name: nginx-config
          mountPath: /etc/nginx/nginx.conf
          subPath: nginx.conf
        - name: other.conf
          mountPath: /etc/nginx/other.conf
          subPath: other.conf
  volumes:
    - name: nginx-config
      configMap:
        name: nginx-config

(注意 mountPath 中文件名的重复，并使用完全相同的 subPath；与绑定(bind)挂载文件相同。)
有关 ConfigMap 的更多信息，请参阅:
https://kubernetes.io/docs/user-guide/configmap/

Note: A container using a ConfigMap as a subPath volume will not receive ConfigMap updates.
