+# 跨Namespace同步Secret和ConfigMap
+
+> 示例：同步 `test` 命名空间下的 `demo-secret` 到 `default` 命名空间下
+
+## JQ实现
+
+1. 准备依赖 `jq`
+
+   - Centos
+
+     ```bash
+     yum install jq -y
+     ```
+
+   - Ubuntu
+
+     ```bash
+     apt install jq -y
+     ```
+
+2. 执行命令
+
+   ```bash
+   kubectl get secret demo-secret -n test -o json \
+    | jq 'del(.metadata["namespace","creationTimestamp","resourceVersion","selfLink","uid"])' \
+    | kubectl apply -n default -f -
+   ```
+
+## SED实现
+
+```bash
+kubectl get secret demo-secret -n test -o json \
+ | jq 'del(.metadata["namespace","creationTimestamp","resourceVersion","selfLink","uid"])' \
+ | kubectl apply -n default -f -
+```
+
