Hey,

Thanks for gist.

If I run 'docker-compose run composer install', it creates a new containter, instead of using the defined one.

It works, just that you get plenty of stopped containers in kitematic with names like composer_composer_1 and so on.

Is that normal behavior? Thanks.

Maybe try docker-compose exec composer install. This should run the command in an already running container.

Hi, I run this command docker-compose run --rm composer install on my service(I ssh to my service). And I got the error message [RuntimeException]/var/www/html/vendor does not exist and could not be created.. But I run this command on my Mac, it's work. I miss something? Thanks.

Sweet and simple! Thank you so much for this gist!

what does this mean in detail?

  command: php -S 0.0.0.0:8000 /app/index.php

Looks port relatd, but you are already setting the port on the very next line.
Thanks!

@blachawk, command: php -S 0.0.0.0:8000 /app/index.php means use php inside the app container to start a web server running at port 8000 that executes /app/index.php. The very next line reads like this: expose port 8000 from the host machine, to port 8000 where the web server is running in the container. So that you can navigate to http://localhost:8000 in your browser and see what /app/index.php shows or does.

Hi guys,

Thanks for the gist

Can you advice how it's better to use composer container when you application need to run composer inside it's own container?
For example, if you use symfony/phpunit-bridge to run tests, it try to install required packages.

Restart policy of 'yes' is not valid (at least now) docker restart policies.
Also, I had to use docker-compose up to install the container.

And...it appears that the remote repository no longer exists.

[tyler.christian@ThisOne my-dir]$ git clone git@github.com:mfacenet/hello-world.git
Cloning into 'hello-world'...
ERROR: Repository not found.
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

Thanks!

It just works (TM)

Thanks, worked for me!

@andyshinn How does it work with PHP 7.2?

Is there some error with PHP 7.2? I don't use PHP daily so I am not sure what the difference might be.

Perfect! thanks for share!
