按照这个文档： discourse/docs/INSTALL-cloud.md at main · discourse/discourse · GitHub 安装，如何指定esr版本。

Basing off my memory here, in the installation process, there will be a part where it says to press CTRL + C if you want to edit the app.yml file, which you can then perform: cd /var/discourse nano containers/app.yml to edit it, then run a rebuild.

You can do a version: xyz in your app.yml file. IIRC under the params section. It should be commented; you can just uncomment the line and specify the version.

按照上面的自动安装命令，命令执行中好像没办法设置 app.yml 吧。

In what way? Can you elaborate? If this was a fresh installatuon, you can do this. But note that you cannot downgrade existing instances to previous versions, only upwards.

手动指定版本应该要走文档结尾的 Advanced Configuration 流程

我是说运行下面的这个命令： wget -qO- https://raw.githubusercontent.com/discourse/discourse_docker/main/install-discourse | sudo bash 这个命令中途如何去修改 app.yml，因为这个命令好像默认安装就是 latest 版本。而我想要安装 esr 版本。

这个好像要安装完了之后，才能编辑，下次构建生效。我想要一开始就指定 esr 版本，不想安装最新版。

非常感谢，因为文档上面没提到过有这一步，导致我很困惑。我会去尝试一下。

You can also not use that script, it’s just a checkout and copying the samples to containers, that’s good for power user configurations. And also reconsider using stable/esr, it feels you will be very unwelcome with support questions in this constellation :slight_smile:

[image] NateDhaliwal: 根据我的记忆，在安装过程中，会有一个提示，要求你按下 CTRL + C 来编辑 app.yml 文件，之后你可以执行以下操作简单安装流程，没有这一步，我是手动中断的，然后编辑 app.yml，再构建就行了。

The simple installation process doesn’t have this step. I manually interrupted it, edited app.yml, and then built it.
