Deployment flow

Aims - Automatically do these:

• add godaddy subdomain

Things you need

• Github Project (You need Admin permission to access 'Setting' page )
• deploy.sh in project root
• AWS access key and secret key
• Key pair for EC2 instance, for example, altitudelabs.pem
• Godaddy username and password

Preparation

• Install ansible using

  pip install ansible
  

• Install boto using

  sudo /usr/bin/python -m easy_install boto
  

• ssh add private key if you have not.

  eval `ssh-agent`
  ssh-add ~/.ssh/altitudelabs.pem
  

• Add AWS access and secret key to ~/.bash_profile

  sudo vim ~/.bash_profile
  

  export ANSIBLE_HOST_KEY_CHECKING=False
  export AWS_ACCESS_KEY={{ aws_access_key }}
  export AWS_SECRET_KEY={{ aws_secret_key }}
