Service 'web' failed to build

Hello,

I’m trying to get a fresh installation of nextcloud working with docker and Portainer.
My choice is to install it using the fpm image because I have a Nginx Proxy in front of my installation, running on the same device.
I’m running all of this on a Raspi 4.

I created a directory at this location /home/leor/nextcloud
Inside I put two files :

  • db.env
  • docker-compose.yml

The content of each file has been copied from the documentation here

I needed to manually create two directories (web and proxy) in order to be able to execute the command docker-compose up -d

Then, it all started well but at one point, I get this error :

Status: Downloaded newer image for nextcloud:fpm-alpine
Building web
[+] Building 0.1s (2/2) FINISHED
 => [internal] load build definition from Dockerfile 0.0s

ERROR: failed to solve: failed to read dockerfile: open /var/lib/docker/tmp/buildkit-mount3861733695/Dockerfile: no such file or directory
ERROR: Service 'web' failed to build : Build failed

I’m stuck here, I can’t find any answer on the internet to resolve this.

I hope to find useful help here.
If you need any information feel free to ask.

Thanks,
Leor

Nevermind, I resolved my issue by putting in the web and proxy folder two new files :

  • Dockerfile
  • supervisord.conf

Where their content has been copied from docker/.examples/dockerfiles/full/fpm at master · nextcloud/docker · GitHub

Then the installation goes well.
I now have another problem with the proxy container

docker-compose up -d

I’m still working on it, here is the result of the command :

Is there something wrong ?

I come back with news.

I find the origin of my problem. I didn’t used the right files to put in proxy and web folders.
You should use those from there :

At this point, I still got the same error but at least my files were correct.
Then, I changed the ports of nextcloud proxy in the docker-compose.yml file

  proxy:
    build: /home/nextcloud/proxy
    restart: always
    ports:
      - 8081:80
      - 8443:443

Then everything started correctly. I assume the adress to access Nextcloud app should be http://hostIP:8081 but I get a 503 error for the moment.
Still looking for resolution.

Okaaaay. Finally.
I found what was wrong in my installation.

The files copied from the github were wrong again.
I saif I was using a nging proxy in front of my installation but I grab the files containing a proxy configuration : it messed up everything.

So I figured out that I needed those files

From insecure folder.

After tweaking a bit the docker-compose.yml file (specially removing 127.0.0.1 in front of the ports) i’m able to access Nextcloud installation page.

Let’s go.

Thank’s to myself.
