- Around line 68-75: The violet push command is passing the literal string
"CLUSTER_NAME" instead of the environment variable; update the command to
reference the env var (use $CLUSTER_NAME) in the --clusters argument so it
expands to the actual cluster name (i.e., change --clusters "CLUSTER_NAME" to
--clusters "$CLUSTER_NAME").
- Around line 148-210: Add the missing heredoc opener so the YAML can be written
to a file: insert a shell heredoc command (e.g., initiating a cat into
kube-proxy-cleanup.yaml with << 'EOF') immediately before the existing ```yaml
block for the BroadcastJob named kube-proxy-cleanup, keeping the ending EOF
already present; ensure you remove or adjust Markdown code fences if needed so
the heredoc writes the raw YAML (apiVersion: operator.alauda.io/v1alpha1, kind:
BroadcastJob, metadata.name: kube-proxy-cleanup) into the file.

- Around line 67-74: In the violet push command, the cluster argument is using
the literal string "CLUSTER_NAME" instead of the environment variable; update
the command invocation (violet push ...) to pass the variable by replacing
"CLUSTER_NAME" with $CLUSTER_NAME so it uses the exported CLUSTER_NAME value
(ensure the exports for PLATFORM_URL, USERNAME, PASSWORD, CLUSTER_NAME remain as
shown).
- Around line 147-208: The YAML snippet for the BroadcastJob (metadata.name:
kube-proxy-cleanup) is missing the heredoc wrapper to create a file; wrap the
YAML with a bash heredoc to write to kube-proxy-cleanup.yaml by adding a leading
line like cat > kube-proxy-cleanup.yaml << 'EOF' before the ```yaml block and a
closing EOF after the end of the YAML so the BroadcastJob manifest
(kube-proxy-cleanup) is correctly emitted to the file.

Add missing heredoc command for YAML configuration.
The YAML block ends with EOF at line 209, but the beginning heredoc command is missing. Users need to know how to create the file with this content.
📝 Proposed fix
Add the heredoc command before the YAML block:
3. Create a BroadcastJob to clean up kube-proxy rules:
+```bash
+cat > kube-proxy-cleanup.yaml << 'EOF'
+```

添加缺失的 heredoc 命令来创建 YAML 配置文件。
YAML 代码块缺少开头的 heredoc 命令。用户需要知道如何使用此内容创建文件。
📝 建议的修复
在 YAML 代码块之前添加 heredoc 命令：
3. 创建清理的 BroadcastJob：
+```bash
+cat > kube-proxy-cleanup.yaml << 'EOF'
+```
+
```yaml
apiVersion: operator.alauda.io/v1alpha1并在 YAML 末尾添加：
type: FileOrCreate
+EOF
