Docker-compose with nginx proxy shows 503 error

Ruby · August 26, 2023, 10:40pm

Hi, all.

I’m trying to install Nextcloud on Docker, cloning the directory.
When running the containers via docker-compose up -d, however, I encountered 503 Service Temporarily Unavailable error, although I didn’t touch anything from the directory.

How could I run properly?

I’ve added some vital information.

System information:

Nextcloud version (eg, 26.0.1):	27.0.2
Operating system and version (eg, Ubuntu 22.04):	Manjaro ARM (rolling release)
Apache or nginx version (eg, Apache 2.4.25):	nginx 1.25.2
PHP version (eg, 8.1):	8.2.9
Database (sqlite or MariaDB or Postgres)	Postgres
Docker (compose)	24.0.2 (2.19.0)
Snap	not used
Is this the first time you’ve seen this error?	yes

The issue you are facing:

Steps to replicate it:

$ git clone https://github.com/nextcloud/docker
$ mv docker/.examples/docker-compose/with-nginx-proxy/postgres/fpm nextcloud
$ cd nextcloud
$ docker-compose up -d
$ curl 192.168.0.2

This is currently any issue with the updater being offline outside of Docker, so that might be what you are encountering in this moment. It is in the process of being resolved afaik. A total guess of course.

So do you mean that waiting for the upcoming fix is the best as of now?

Honestly hard to say since you provided no logs or details.

After modifying the docker-compose.yml file as below, it works fine on port 80 (http).

$ diff docker-compose.yml.orig docker-compose.yml
36c36
<       - VIRTUAL_HOST=
---
>       - VIRTUAL_HOST=nextcloud.local
62a63,64
>     environment:
>       - DEFAULT_HOST=nextcloud.local

In other words, services.web.environment must have VIRTUAL_HOST=nextcloud.local, and services.proxy.environment must have DEFAULT_HOST=nextcloud.local. If environment section is missing, feel free to append it.

And executing docker-compose build and docker-compose up -d, in the order, makes Nextcloud working.

Although this solution is working well on port 80 (http), supporting port 443 (https) requires more steps, but I have no plan to describe these steps. In my opinion, this should be regarded as some different issue, not this.
