Shopware 5 Development Version using Docker

Shopware 5
,
1

When I’m try to setup shopware 5 development version using Docker.

so I ran ./psh.phar docker:start which output this:

pcg@pcg-Latitude-E6410:/var/www/shopwareic.com/public_html$ ./psh.phar docker:start

I’m not exactly sure how to fix this. I’m pretty new to docker. Anyone know why it is giving me a not found „Service ‚app_mysql‘ failed to build“

I’m using Ubuntu.
