the procedure to deploy rails on ec2

[hi-ogawa]

procedure

• install and run docker on the ec2 instance (ubuntu 14.04)

• install and run docker on local mac os

• rails setup on a docker image at local
  • read through this https://docs.docker.com/userguide/
  • write a docker file to setup rails as i did in my first aws ec2 instance
  • https://docs.docker.com/userguide/dockerimages/
• pull the created docker image and run in the new ec2 instance

(preferred)

• understand how mysql work (with rails (is connection via socket or port?))
• then separate database as another docker container
• then linking together
  • https://docs.docker.com/userguide/dockerlinks/
  • https://docs.docker.com/compose/.

[hi-ogawa]

is rbenv necessary or does it even contradict to the principles of docker?

[hi-ogawa]

preparation

• put docker files in git repository
  • Dockerfile
  • Makefile

the procedure to get them work on ec2 instance

• lanuch ec2 instance (assume ubuntu14.04)
• ssh to ec2
• install docker (which has git as a dependency, so you don't have to install git after this)
  • curl -sSL https://get.docker.com/ | sh
  • sudo usermod -aG docker ubuntu
  • logout and log back in.
• git clone app repository
  • git clone https://github.com/hi-ogawa/wordCollector.git
  • cd wordCollector
  • git pull origin backbone
• run docker commands to launch app
  • docker build -t hiogawa/rails:app .
  • docker run --name db -e MYSQL_ROOT_PASSWORD=dontcare -d mysql
  • docker run --name web --link db:db -p 80:80 -d hiogawa/rails:app
  • docker exec -it web bash
  • eval "$(rbenv init -)" && rake db:create && rake db:migrate
• somehow I need to give aws access key to rails app.
  • stop giving aws credentials via file.

[hi-ogawa]

finally, gave up using docker for now. so what i need to do from now is

• learn how to give aws credentials via environment variables
  • export AWS_ACCESS_KEY_ID=<id> AWS_SECRET_ACCESS_KEY=<key>
  • (rake db:setup)
  • rails s
• create makefile which installs rails environment on ec2 ubuntu14.04 instances
  • or create amazon image?
• learn how to separate database resource upon aws
  • launch RDS and put the RDS and EC2 instances into the same security group

[hi-ogawa]

• launch ec2 instance from my own custom rails ami
• git clone https://github.com/hi-ogawa/wordCollector.git
• bundle install
• put env vars into ~/.rbenv/vars like
  • echo "SECRET_KEY_BASE=$(rake secret)" >> ~/.rbenv/vars
  • (aws id), (aws key), (rails env)
• (rake db:create, rake db:migrate)
• nohup rbenv sudo passenger start -p80 &> /dev/null &
  • rbenv sudo passenger start -p80 --nginx-config-template config/nginx.conf.erb
