kubectl - 解析configmap以获取部署验证的详细信息

Question

How do I get a specific value for a parameter ? For example - How do I search for the below:

1) password: ${dpt_password}

2) bootstrap-servers: xl-kb01.inpod.com:19093,xl-kb02.inpod.com:19093

3) springframework: INFO

kubectl get cm inpod -o jsonpath={.data}


map[application.yaml:ds:
  hosts: '-'
  keyspaces: '-'
  password: ${dpt_password}
  port: '9042'
  username: ${dpt_username}

If you are asking about how to push variables into configmap, you can do it by creating cm from file. Here is a simple example within shell script:

#!/bin/bash
echo "Enter username: "
read usr
echo "Enter password: "
read pass
echo -e "{password: " $pass", username: " $usr" }" > env.json
kubectl create configmap env-cm --from-file=env.json
kubectl get cm env-cm -o jsonpath={.data}

You can populate your source file with any kind of variable and use it for cm creation.
