How I could restart the web server in docker

Support Self-hosting

AI-generated summary

The discussion revolves around restarting the web server in Docker. berniegao initially asked if there’s a way to restart the web server similar to reloading config files in a manual Rails server installation. watchmanmonitor suggested using ./launcher stop app and ./launcher start app, but berniegao clarified that this method restarts the entire Docker container.

sam then provided the correct method: ./launcher enter app followed by sv restart unicorn. Jared_Smith1 asked if exiting the app is necessary after this step.

The conversation also touched on troubleshooting issues, such as SpaceMonkey encountering an error when trying to run ./launcher enter app, which Stephen helped resolve.

Additionally, trusktr asked if there’s a UI button to restart the server, and jomaxro explained that there isn’t one. trusktr suggested that a UI button for rebuilding would be convenient.

jomaxro clarified that most changes to the app.yml require a rebuild, which cannot be triggered from the UI. Stephen added that some settings, such as SMTP, can be updated and picked up immediately by running ./launcher destroy app and ./launcher start app, while others require a rebuild.

by manual installation, I could cease the rails server to reload the config files. Is there something like the rails server within docker?

This seems to work for me:

3

doing so will restart the entire docker container. what I trying to do is to restart the web server without touch the container, such as using “rails server” and then stop it without utilizing docker.

4

why are you trying to do this, not following at all. Anyway here you go.

cd /var/discourse 
./launcher enter app
sv restart unicorn
5

should we exit app after this step? I’m so new to this if it wasn’t obvious

I have discourse installed via docker. After upgrading yesterday my discourse has been down. I am trying to run ./launcher enter app
from
/var/www/discourse/
I am getting the error ./launcher: No such file or directory Is there way for me to search the correct directory for this command?

/var/www/discourse doesn’t exist outside the app, if you can see that path you’re already inside discourse.

Type exit - does that end the ssh connection, or bring you back to /var/discourse?

UI에서 서버를 재시작할 수 있는 버튼이 있나요? 새 버전이 출시되면 업그레이드 버튼이 표시되는 것을 확인했는데, 이 버튼이 재시작을 수행하는 것 같긴 하지만, 재시작만을 위한 버튼은 찾지 못하겠습니다.

아니요, 없습니다. 왜 웹 서버를 재시작해야 합니까? 해결하려는 문제는 무엇인가요?

서버를 재시작해서 app.yml 변경 사항이 적용되는지 확인하고 싶었습니다. 재빌드도 필요한 것 같습니다. 관리자 페이지의 업그레이드 섹션 근처에 재빌드를 위한 UI 버튼을 추가하면 편리할 것 같습니다.

11

app.yml 파일에 대한 대부분의 변경 사항은 재빌드를 필요로 합니다. 재빌드는 UI에서 트리거할 수 없으며, docket 컨테이너 외부에서 서버 자체에 연결해야 합니다.

12

SMTP와 같은 설정은 yml 파일에서 업데이트할 수 있으며, 아래 명령을 통해 즉시 적용됩니다:

./launcher destroy app
./launcher start app

반면 플러그인 등 기타 항목은 재빌드가 필요합니다.
