Rails Microservices on Docker w/Kafka Example

How-To

• Run docker-compose build
• Run docker-compose run auth_web rake db:create
• Run docker-compose run auth_web rake db:migrate
• Run docker-compose run namer rake db:migrate
• Run docker-compose up

In a separate terminal window, run:

• docker-compose run namer racecar NameRandomizerConsumer

Then make a POST request to localhost:3000/users to create a user with the following parameters:

• full_name
• email
• password
• password_confirmation

That post request will create a user and send a message to the NameRandomizerConsumer located in the name_randomizer Rails app ( app/consumers/name_randomizer_consumer.rb ). The consumer will then process this request and make a random name entry in the db with the user id of the user created.

If this DOES NOT work, please check your hosts file (/etc/hosts) and add:

127.0.0.1 kafka
