Continuous Deployment

1. Generate a dedicated SSH key

ssh-keygen -t rsa -b 4096 -C 'build@travis-ci.org' -f ./deploy_rsa

2. Encrypt the private key to make it readable only by Travis CI

travis encrypt-file deploy_rsa --add

3. Copy the public key onto the remote SSH host

ssh-copy-id -i deploy_rsa.pub <ssh-user>@<deploy-host>

4. Stage the modified files into Git

git add deploy_rsa.enc .travis.yml

5. add code below to .travis.yml

addons:
  ssh_known_hosts: 140.82.63.62

after_success:
  - ./deploy.sh

6. Install docker and clone github project on server
