I run:- HTTP_PORT=8080 HTTPS_PORT=8443 SERVER_NAME=foo.localhost docker-compose up and get the error above with it counting down to zero. The containers/services fail to launch?

docker ps

I've tried DATABASE_URL: mysql://${MYSQL_USER:-root}:${MYSQL_PASSWORD:-password}@gk_app:3567/${MYSQL_DB:-gk_app}?serverVersion=13&charset=utf8 with different ports: 3567 & 3306 with no success?

Is anyone savvy with https://github.com/dunglas/symfony-docker/blob/main/docker-compose.yml and swapping postgres for mysql?

Edit: Trying:- DATABASE_URL: mysql://${MYSQL_USER:-root}:${MYSQL_PASSWORD:-password}@localhost:3567/${MYSQL_DB:-gk_app}?serverVersion=13&charset=utf8,

DATABASE_URL: mysql://${MYSQL_USER:-root}:${MYSQL_PASSWORD:-password}@127.0.0.1:3567/${MYSQL_DB:-gk_app}?serverVersion=13&charset=utf8

& DATABASE_URL: mysql://${MYSQL_USER:-root}:${MYSQL_PASSWORD:-password}@database:3567/${MYSQL_DB:-gk_app}?serverVersion=13&charset=utf8

all of these produce the same error?

Answer 1

Make sure the DATABASE_URL is checked without cmets: https://github.com/dunglas/symfony-docker/pull/107
