Unable to launch the Demo Docker instlal

[TristanPouliquen]

API Platform version(s) affected: The one gotten by the github generate tool

Description
I've generated a repository (https://github.com/TristanPouliquen/api-platform-demo) with the https://github.com/api-platform/api-platform/generate URL given in the Get started documentation.

Running docker-compose pull works allright, but when I run docker-compose up, I get the following error:

Step 16/32 : RUN set -eux; 	composer install --ignore-platform-req=php --prefer-dist --no-dev --no-scripts --no-progress; 	composer clear-cache

How to reproduce

1. Generate a repository from API Platform
2. Clone it on your computer
3. Run docker-compose pull & docker-compose up

That weird, can you do docker-compose pull and try again?

[TristanPouliquen]

No change after multiple docker-compose pull on my side sadly.

Personnaly, I've just git clone from master (Merge pull request #1710 from TorbenKoehn/patch-1)

[dunglas]

That's weird because this option exists. I'll take a look.

This error only occurs if you have an outdated composer image. Run docker pull composer:latest to fix the issue.
