正在尝试将GitLab CE docker容器连接到OpenLDAP docker容器

我是Docker的新手，我正在尝试利用Docker的网络做一些事情。我有两个容器，一个是GitLab，另一个是OpenLDAP，我希望我的GitLab服务器可以通过OpenLDAP身份验证进行设置。我有下面的两份作文。Gitlab compose主要是复制和粘贴，因为我实际上并不100%确定环境变量的设置应该是什么，以便它与OpenLDAP容器进行内部通信。我希望他们可以通过一个用户定义的桥接器（名为“loworkNetwork”）完全在内部进行通信，我在开始这些组合之前就开始了这个桥接器

我已经弄明白了！在我的例子中，我所要做的就是将主机更改为容器的名称。因此，在我的gitlab docker compose中，我只是将“ldap主机”更改为“openldap”，因为这是我容器的名称
