Azure kubernetes-python读取configmap吗? [英] Azure kubernetes - python to read configmap?

问题描述

我正在尝试对python应用程序进行Docker化，并希望从configmap中读取配置设置.如何在python中读取configmap?

I am trying to Dockerize the python application and want to read the configuration settings from the configmap. How do I read configmap in python?

推荐答案

使用配置文件创建configMap:

Create a configMap with the configuration file:

$ kubectl create configmap my-config --from-file my-config.file

将configMap安装在Pod的容器中，并从您的应用程序中使用它:

Mount the configMap in your Pod's container and use it from your application:

        volumeMounts:
        - name: config
          mountPath: "/config-directory/my-config.file"
          subPath: "my-config.file"
      volumes:
        - name: config
          configMap:
            name: my-config

现在，您的配置文件将在/config-directory/my-config.file 中可用.您可以从Python代码中读取它，如下所示:

Now, your config file will be available in /config-directory/my-config.file. You can read it from your Python code like below:

config = open("/config-directory/my-config.file", "r")

您还可以将configMap的数据用作容器的环境-

You can also use configMap's data as the container's env - Define container environment variables using configMap data

config = os.environ['MY_CONFIG']
