기타 서비스와 함께 Discourse를 호스팅하려면 RAM이 얼마나 필요할까요?

지원 자체 호스팅

디스커스 포럼에서 1GB에서 최대 2GB의 메모리가 적당하다는 글을 읽었으나, 이 두 옵션으로는 웹사이트가 매끄럽게 실행되지 않습니다. 4GB 메모리로 docker-compose 파일을 실행하면 90~95%의 사용률을 기록하며, 이는 상당히 높은 수치입니다. docker-compose 파일에는 제가 만든 정적 HTML 웹사이트와 nginx 프록시가 포함되어 있습니다. 디스커스의 설정이나 트릭을 통해 낮은 RAM 환경에서도 더 원활하게 실행되도록 하는 방법이 있는지 알려주시면 감사하겠습니다.

You need to tweak the amount of workers and the DB buffer. So, the options you would need to tweak would be:

  • db_shared_buffers
  • UNICORN_WORKERS

Here you can see the estimates of usage per Unicorn

Discourse is able to run with 512MB of RAM its not a good experience but it’s possible. You issue is that Discourse reviews the server (as the whole node) resources and plans the resource usage to take advantage of as most resources as possible because Discourse makes the assumption it will run alone.

Can you share the docker-conpose file here so we can make appropriate suggestions?

Here is the docker-compose file. I had to remove some of the images links since I cannot post more than 2, however, this should be good. Where would I place the DB buffer environment variable?

If you wrap your raw code with lines that contain only ``` they will be much easier to read.

As step one, I recommend that you use ./launcher to build and launch your Discourse instance. If you want, you can use ./launcher to build it and then launch it with docker-compose (at least I’ve done similar to build and launch Discourse images with kubernetes).

6

You are using bitnami images and those are completely unsupported by Discourse maintainers and will probably use more RAM than using the Discourse official Standard Installation

7

why are bitnami images still so popular?

answering my own question, it seems like bitnami is the only idiomatic docker option, where the builds are deterministic and centered around ENV variables. Discourse by default uses docker but treats it more like bootstraps for traditional build systems that require you to ssh in and setup/maintain from terminal.

8

That’s right. If you want help here, you follow the standard install. It you want Help from Bitnami, you can use their image.
