如何在kubectl中查看当前上下文的配置详细信息？

Question

我想查看以下命令显示的“ config”详细信息：

kubectl config view

但是，这显示了所有上下文的整个配置详细信息，如何过滤（或有另一个命令）以查看CURRENT上下文的配置详细信息？

Answer 1

使用以下命令获取包括证书的完整配置

kubectl config view --minify --flatten

Answer 2

kubectl config view --minify 仅显示当前上下文

Answer 3

执行此操作的云原生方法是使用命令的 JSON 输出，然后使用以下命令对其进行过滤jq：

kubectl config view -o json | jq '. as $o
    | ."current-context" as $current_context_name
    | $o.contexts[] | select(.name == $current_context_name) as $context
    | $o.clusters[] | select(.name == $context.context.cluster) as $cluster
    | $o.users[] | select(.name == $context.context.user) as $user
    | {"current-context-name": $current_context_name, context: $context, cluster: $cluster, user: $user}'

{
  "current-context-name": "docker-for-desktop",
  "context": {
    "name": "docker-for-desktop",
    "context": {
      "cluster": "docker-for-desktop-cluster",
      "user": "docker-for-desktop"
    }
  },
  "cluster": {
    "name": "docker-for-desktop-cluster",
    "cluster": {
      "server": "https://localhost:6443",
      "insecure-skip-tls-verify": true
    }
  },
  "user": {
    "name": "docker-for-desktop",
    "user": {
      "client-certificate-data": "REDACTED",
      "client-key-data": "REDACTED"
    }
  }
}

这个答案帮助我弄清楚了一些 jq 位。
