Hello everyone. In recent installations I always get a composer error while booting the docker sdk. The messag is:

ERROR [spryker_app_dependencies 5/5] RUN --mount=type=cache,target=/home/spryker/.composer/cache,from=composer_cache,source=/cache     composer install --no-interaction --optimize-autoloader --no-dev   0.

I'm using Centos as an operation system. Thx

Hello Robert, What version of dockers? Do you have experimental docker features enabled?

Docker Version: 19.03.5

Got it already. Same error 😞

Ah. So you had it worked. At that point I assume docker layers would be corrupted. If you are willing, you can try to prune docker. Or even delete its data. Do you need guide for such?

Also done. All volumes and images are pruned

Sometimes it happens. In some cases even rebooting helps.

First I want to reinstall docker

I suggest

sudo rm -rf /var/lib/docker

after docker shutdown.

Wow now it works

Sometimes happens. ) Glad to help.
