Symfony Docker quick test
A quick test to show how Symfony is slow using Docker / Docker beta (yup, the one that
leverages OS X virtualization technology) on OS X.
This is due to the volume share. Using Symfony in a container without sharing volume is very fast (~20ms in dev mode).
docker build -t sf-test . docker run -d -p 8080:8080 -v `pwd`:/var/www/symfony_project --name symfony_docker_test sf-test
Make sure that Composer is done running and that the server is started:
docker logs -f symfony_docker_test
Have a look at Symfony's default homepage
Open in your browser the following URL: http://localhost:8080.
The example is much faster on the
master branch since I moved the
vendor (biggest win with this one) directories outside of the shared directory.
You can switch to the
non-shared-vendor branch to make tests with
vendor dirs in the shared volume (which is the default Symfony install).
