./launcher destroy app && ./launcher start app 是否会移除构建的 Docker 镜像？

Hi there, does this help?

@Discourse

Well, you don’t always need to rebuild

Doing a rebuild will often fix things that seem broken, but it takes a while. There are times when a full rebuild is not necessary; the above is usually the best advice, but If you change just SMTP settings, you can do just this to apply them without doing a full rebuild:

cd /var/discourse
./launcher destroy app
./launcher start app
