Getting started

Pre-build steps

In development, we are using a dev centric docker entrypoint, one that doesn't come right out of the box For some occassions, we may want to check if we can execute/run ./bin/docker-dev-entrypoint

ll bin
-rw-r--r--  1 raymondgabriel  staff   222B May 17 10:57 docker-dev-entrypoint
-rwxr-xr-x  1 raymondgabriel  staff   223B May  6 12:49 docker-entrypoint
-rwxr-xr-x  1 raymondgabriel  staff   141B Apr 19 08:25 rails
-rwxr-xr-x  1 raymondgabriel  staff    90B Apr 19 08:25 rake
-rwxr-xr-x  1 raymondgabriel  staff   984B Apr 19 08:25 setup

If said file had no execute access rights (x) we need to add it for the current user.

chmod +x bin/docker-dev-entrypoint

Building in development

docker build -f dev.dockerfile -t rails_demo .

Mounting your development application as a volume

Advantage of this is whenever you do changes on your code, it is immediately reflected. And to do that, we use the -v option. Else, you may need to stop start each time.

docker run -p 3000:3000 -v $(pwd):/rails rails_demo

Run migration

docker-compose run web bin/rails db:migrate RAILS_ENV=development

Rails console

docker-compose run web bin/rails console -e development
