+# 示例: 改变镜像名称和标签
+
+首先构建一个工作空间：
+
+<!-- @makeWorkplace @testAgainstLatestRelease -->
+```bash
+DEMO_HOME=$(mktemp -d)
+```
+
+创建包含pod资源的 `kustomization`
+
+<!-- @createKustomization @testAgainstLatestRelease -->
+```bash
+cat <<EOF >$DEMO_HOME/kustomization.yaml
+resources:
+- pod.yaml
+EOF
+```
+
+创建pod资源声明
+
+<!-- @createDeployment @testAgainstLatestRelease -->
+```bash
+cat <<EOF >$DEMO_HOME/pod.yaml
+apiVersion: v1
+kind: Pod
+metadata:
+  name: myapp-pod
+  labels:
+    app: myapp
+spec:
+  containers:
+  - name: myapp-container
+    image: busybox:1.29.0
+    command: ['sh', '-c', 'echo The app is running! && sleep 3600']
+  initContainers:
+  - name: init-mydb
+    image: busybox:1.29.0
+    command: ['sh', '-c', 'until nslookup mydb; do echo waiting for mydb; sleep 2; done;']
+EOF
+```
+
+`myapp-pod` 包含一个init容器和一个普通容器，两者都使用 `busybox：1.29.0` 镜像。
+
+在 `kustomization.yaml` 中添加 `images` 字段来更改镜像 `busybox` 和标签 `1.29.0` 。
+
+- 通过 `kustomize` 添加 `images`：
+    <!-- @addImages @testAgainstLatestRelease -->
+    ```bash
+    cd $DEMO_HOME
+    kustomize edit set image busybox=alpine:3.6
+    ```
+
+- 将`images`字段将被添加到`kustomization.yaml`：
+    > ```yaml
+    > images:
+    > - name: busybox
+    >   newName: alpine
+    >   newTag: 3.6
+    > ```
+
+构建 `kustomization`
+<!-- @kustomizeBuild @testAgainstLatestRelease -->
+```bash
+kustomize build $DEMO_HOME
+```
+
+确认`busybox`镜像和标签是否被替换为`alpine：3.6`：
+<!-- @confirmImages @testAgainstLatestRelease -->
+```
+test 2 = \
+  $(kustomize build $DEMO_HOME | grep alpine:3.6 | wc -l); \
+  echo $?
+```
