Cannot create container for service - many of them

[jramiresbrito]

After following the setup instructions, I've successfully installed it using docker-compose run composer create-project.
Then, in the next step, to run the containers, docker complains about the name of the containers:

Creating -composer ... error

ERROR: for -composer  Cannot create container for service composer: Invalid container name (-composer), only [a-zA-Z0-9][a-zA-Z0-9_.-] are allowed

ERROR: for mailhog  Cannot create container for service mailhog: Invalid container name (-mailhog), only [a-zA-Z0-9][a-zA-Z0-9_.-] are allowed

ERROR: for mysql  Cannot create container for service mysql: Invalid container name (-mysql), only [a-zA-Z0-9][a-zA-Z0-9_.-] are allowed

ERROR: for composer  Cannot create container for service composer: Invalid container name (-composer), only [a-zA-Z0-9][a-zA-Z0-9_.-] are allowed

the thing is the composer can't find the environment variables set in .env file and it defaults to a blank string:

WARNING: The APP_NAME variable is not set. Defaulting to a blank string.
WARNING: The DOMAIN variable is not set. Defaulting to a blank string.
WARNING: The DB_ROOT_PASSWORD variable is not set. Defaulting to a blank string.

How to make it work?

PS: Sorry about the off-topic. In the step of adding the domain to the hosts file, I've overridden the old entry:

127.0.0.1 localhost

to

127.0.0.1 myapp.local

Is that correct, or should I just add another entry?

Hello,

It cannot find .env because I suspect you haven't created it. I had this same issue and each time I had to manually create the .env file. Perhaps there is something wrong with the create script as it creates one .env but I believe it doesn't create the root .env. Try duplicating the root .env.example and renaming to .env and then run the create-project command again.

Also with your domain question, just add another entry, don't think there is any need to override anything.

Hope this helps

I have it created. Actually I've just removed the .example from all extensions here's my tree

@jramiresbrito what does your .env file in the root folder look like? You need that also, not just the src/.env

[toshuyu]

@jramiresbrito you need to run both docker-compose run composer create-project and docker-compose up at the root of the project (not under /cli folder for example)
