  • k8s configmap 挂载配置文件

    转自https://blog.csdn.net/weixin_34102807/article/details/85965725

    1、新建ConfigMap

    apiVersion: v1
    kind: ConfigMap
    metadata:
      name: test-conf
      namespace: default
      labels:
        name: test-conf
    data:
      test.properties: |
        db.url=jdbc:oracle:thin:@172.16.10.178:1521:orcl
        db.user=sz_res
        db.passwd=sz_res
      test2.properties: |
        xxxxxxxxxxxxxxxxxxxxxxxxxxxx
    

    2、新建deployment

    apiVersion: extensions/v1beta1
    kind: Deployment
    metadata:
      name: test-app
      namespace: default
    spec:
      replicas: 1
      template:
        metadata:
          labels:
            app: test-app
        spec:
          containers:
            - name: test-container
              image: test/tomcat:v1
              imagePullPolicy: Always
              volumeMounts:
                - name: test
                  mountPath: /usr/local/tomcat/webapps/test/WEB-INF/classes/test.properties
                  subPath: path/to/test.properties
                - name: test2
                  mountPath: /usr/local/tomcat/webapps/test/WEB-INF/classes/test2.properties
                  subPath: path/to/test2.properties
          volumes:
            - name: test
              configMap:
                name: test-conf
                defaultMode: 0777
                items:
                - key: test.properties
                  path: path/to/test.properties
            - name: test2
              configMap:
                name: test-conf
                items:
                - key: test2.properties
                  path: path/to/test2.properties
    

    挂载容器内部的文件的权限。(必须是介于0和0777(八进制)之间的数字,包括两者在内)

    其实我没搞懂path/to/的意思
    不过照着搬,的确好用,那就当作固定用法吧,

    本人水平有限,还在不断学习中 难免有很多错误或者遗漏,望见谅
