我使用 kubernetes 掌舵 Wordpress 安装，我使用 Argo CD 管理一切。如何将 sidecar 容器添加到此部署？

我已经安装了 Wordpress，现在我需要将 wp-content 与 git 存储库同步，因为它是更新文件的唯一方法（bitnami wordpress 是非 root 容器，我无法创建 sftp）。

有人建议添加这个：

sidecars:
  - name: git-sync
    image: bitnami/git:2.32.0-debian-10-r24
    imagePullPolicy: IfNotPresent
    command:
      - /bin/bash
      - -ec
      - |
        [[ -f "/opt/bitnami/scripts/git/entrypoint.sh" ]] && source "/opt/bitnami/scripts/git/entrypoint.sh"
        while true; do
            #Add here your commands to synchronize the git repository with /bitnami/wordpress/wp-content
            sleep 60
        done
    volumeMounts:
      - mountPath: /bitnami/wordpress
        name: wordpress-data
        subPath: Wordpress

但我正在努力，但我不确定我做得很好。

在ReplicaSet清单中，containers是一个列表。您可以通过向该列表添加更多容器来添加边车。

由于您正在尝试同步一些静态资产，您可能会发现init 容器是更好的选择，因为它会在您的主容器启动之前完成。
