Build fails out of the box

[razshare]

Similar to https://github.com/dunglas/symfony-docker/issues/173 but different error. Hello, I'm running sudo docker-compose up --build straight after cloning the template and it fails with the following message:

I haven't made any changes to the template at all.

I've tried this on WSL Ubuntu 20.04 and Ubuntu 18.04 native and I'm getting the same error.

This is what docker version gives me:

• on WSL Ubuntu 20 lts

  
  Client: Docker Engine - Community

  API version:       1.41

Some help would be much appreciated!

Can you try to do a docker pull before?

[razshare]

TLDR;

Looks like that fixed it, thanks a lot!

What I did

I had the freedom to run docker image prune and docker container prune, so I did. I had already ran prune before, but that alone didn't fix it.

Then I ran docker pull for these images

• https://github.com/dunglas/symfony-docker/blob/1d4f00d64fd0f097814ac14ecc933dd57cb38747/Dockerfile#L11
• https://github.com/dunglas/symfony-docker/blob/1d4f00d64fd0f097814ac14ecc933dd57cb38747/Dockerfile#L117
• https://github.com/dunglas/symfony-docker/blob/1d4f00d64fd0f097814ac14ecc933dd57cb38747/Dockerfile#L125

So that would mean

• docker pull php:8.0-fpm-alpine
• docker pull caddy:2
• docker pull caddy:2-builder-alpine

And at this point the build succeeded with docker-compose up --build.
