如何将 git sync 的 sidecar 容器添加到 wordpress helm 部署？
How to add sidecar container with git sync to wordpress helm deployment?
我使用 kubernetes helm Wordpress 安装，我使用 Argo CD 管理所有内容。如何将 sidecar 容器添加到此部署？
我已经安装了 Wordpress，现在我需要的是将 wp-content 与 git 存储库同步，因为它是更新文件的唯一方法（bitnami wordpress 是非根容器，我无法创建 sftp） .

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 container 是更好的选择，因为它将在您的主容器启动之前完成。
