Gitlab CI SSH Deploy

1. Create SSH Key on Remote host
   

 $ remote-server: ssh-keygen -o -t rsa -b 4096 -C "yoru@email.com"

2. Copy Generated Private key from remote Server

$ remote-server: cat .ssh/id_rsa

3. Save this Generated Private Key in to Gitlab as this case LIVE_SSH_KEY

4. Generate SS Key for gitlab-runner or root user from Gitlab Server

$gitlab-runner@gitlab-server: ssh-keygen -o -t rsa -b 4096

5. Write Gitlab Runner Public key on the Remote Server

$gitlab-runner@gitlab-server: cat ~/.ssh/id_rsa.pub | ssh yoursshusername@remote-server.com 'cat >> .ssh/authorized_keys'

Now, SSH without Password connection completed.

6. Creating our gitlab-ci.yml for Auto deployment (For information, in this example, i have two http request added for DB update actions and etc., if you not need, please not using this curl requests)

image:  ubuntu

before_script:
  - 'which ssh-agent || ( apt-get update -y && apt-get install openssh-client -y )'
  - eval $(ssh-agent -s)
  - mkdir -p ~/.ssh
  - echo "$DEV_SSH_PRIVATE_KEY" | tr -d '\r' > ~/.ssh/id_rsa
  - chmod 700 ~/.ssh/id_rsa
  - eval "$(ssh-agent -s)"
  - ssh-add ~/.ssh/id_rsa
  - ssh-keyscan -H 'remote-server.com' >> ~/.ssh/known_hosts
  - apt-get install rsync -y -qq
  - apt-get install curl -y -qq
