你可以通过this JSON gist下载
curl -s https://gist.githubusercontent.com/sputnick-dev/7da057b951c182785dfb837194388350/raw/eaf064c6b44c8304e111fa4e6ee3638d47a4ef48/object.json > object.json
有没有办法获取/提取configMapRef的所有名称属性？
(搜索了here个标签[xidel][json]，只有两个匹配).
Expected output:
db-mssql-asd-connection
db-postgre-asd-connection
app-url
这是一个简单的例子，其中我得到xidel来解析json，并带有简短的样本:
$ cat object.json
{
"apiVersion": "apps/v1",
"kind": "Deployment",
"metadata": {
"annotations": {
"deployment.kubernetes.io/revision": "1"
}
}
}
$ xidel -e '($json).metadata.annotations["deployment.kubernetes.io/revision"]' -s object.json
{
"deployment.kubernetes.io/revision": "1"
}
