Not able to add SSH Key...GitLab CI

,

I’ve setup a CI/CD pipeline for the deployment of my MEAN App on DigitalOcean Droplet. I am having problems setting up SSH for deployment. Here’s my gitlab CI configuration

image: trion/ng-cli-karma

cache:
  paths:
  - wiki-quotes-client/node_modules/
  - wiki-quotes-server/node_modules/


stages:
    - test
    - build
    - deploy

test_server:
  script:
   - cd wiki-quotes-server
   - npm install
   - npm run test

test_client:
    script:
        -  cd wiki-quotes-client
        -  npm install
        -  ng test --watch=false

build_angular:
  only:
    - master
  stage: build
  script:
    - npm install
    - cd wiki-quotes-client
    - ng build --prod
  artifacts:
    paths:
      - wiki-quotes-client/dist/wiki-quotes-client/.

deploy:
  only:
    - master
  stage: deploy
  script:
    - apt-get update -qq
    - apt-get install -qq git
    - 'which ssh-agent || ( apt-get update -y && apt-get install openssh-client -y )'
    - eval $(ssh-agent -s)
    - echo "$SSH_KEY" | tr -d '\r' | ssh-add - > /dev/null
    - mkdir -p ~/.ssh
    - chmod 700 ~/.ssh
    - ssh-keyscan gitlab.com >> ~/.ssh/known_hosts
    - chmod 644 ~/.ssh/known_hosts
    - '[[ -f /.dockerenv ]] && echo -e "Host *\n\tStrictHostKeyChecking no\n\n" > ~/.ssh/config'
    - ssh goutambseervi@xxx.xx.xxx.xxx -tt -o StrictHostKeyChecking=no 'cd  ~/wikiquotesapp; git pull; cd wiki-quotes-server; npm install; npm run start:prod'

This is the ouput for the deploy job…

I had almost the same problems.You need to make sure that your SSH Private Key is not password protected. If you are going to make a new one via Command, just press enter when it asks you for a password.
