#!/bin/bash
test2="java/haoqipei"
test1="jjjjjjjjjj/bbbbb"

echo '{"kind":"deployments","namespace":"default","name":"qqipei","images":{"$test1":"$test1:$test2"}}'
echo '{"kind":"deployments","namespace":"default","name":"qqipei","images":{"'$test1'":"'$test1:$test2'"}}'

执行结果如下

{"kind":"deployments","namespace":"default","name":"qqipei","images":{"$test1":"$test1:$test2"}}
{"kind":"deployments","namespace":"default","name":"qqipei","images":{"jjjjjjjjjj/bbbbb":"jjjjjjjjjj/bbbbb:java/haoqipei"}}

外层单引号起到变量引用得作用
