关于 Mattermost 服务端的安装搭建在此不做赘述，如果有朋友需要经验可以留言评论。我使用的是官方的 Dockerfile 构建并运行的。主程序 Dockerfile 位于 app/Dockerfile，mm 官方 GitHub 仓库地址: https://github.com/mattermost/mattermost-server

VOLUME ["/mattermost/data", "/mattermost/logs", "/mattermost/config", "/mattermost/plugins", "/mattermost/client/plugins"]修改 MM_VERSION 为 7.8.0 之后发现卡在了 # Get Mattermost 的步骤，原因是与官方的服务器网络不通畅，下载速度特别慢，还容易丢失连接。
curl https://releases.mattermost.com/$MM_VERSION/mattermost-$MM_VERSION-linux-amd64.tar.gz?src=docker-app | tar -xvz将此压缩包下载到本地， https://releases.mattermost.com/7.8.0/mattermost-7.8.0-linux-amd64.tar.gz?src=docker-app
然后上传到我的 Seafile，生成分享链接后通过 curl 获取文件直链，参考文章 获取 seafile 分享的文件直链 ，再更改 Dockerfile，就可以很快的 docker-compose build 了。
当时用 curl/wget -O mattermost-7.8.0-linux-amd64.tar.gz 都没有成功，拿到文件直链轻松解决。 https://emby.940304.xyz:23399/seafhttp/files/ac915dbb-14b7-4815-80c9-2d989f1830a2/mattermost-7.8.0-linux-amd64.tar.gz.tar
