Configure SSH into AWS EC2
1. Generate SSH Key
cd ~/.ssh
ssh-keygen -t rsa -b 4096 -C "your_email@example.com"
Enter file name: "key_name"
ls and list out files of .ssh folder, you should be seeing "key_name" and "key_name.pub"
- Add public key to authroized keys
cat github-actions.pub >> ~/.ssh/authorized_keys
For detailed information on SSH Key generation process check this reference: https://zellwk.com/blog/github-actions-deploy/
2. Set Github Secrets
SSH_PRIVATE_KEY: private key that we created on ec2
HOST_NAME / IP_ADDRESS: Elastic IP or IP of EC2
USER_NAME: user name of the ec2 user.
3. Create a branch_name.yml ( for dev branch dev.yml ) file under .github/workflows
Update the dev to your branch name
name: Deploy
on:
push:
branches: [ dev ]
jobs:
Deploy:
name: Deploy to EC2
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v2
- name: Build & Deploy
env:
PRIVATE_KEY: ${{ secrets.SSH_PRIVATE_KEY }}
HOSTNAME: ${{secrets.SSH_HOST}}
USER_NAME: ${{secrets.USER_NAME}}
run: |
echo "$PRIVATE_KEY" > private_key && chmod 600 private_key
ssh -o StrictHostKeyChecking=no -i private_key ${USER_NAME}@${HOSTNAME} '
# Now we have got the access of EC2 and we will start the deploy .
cd /home/ubuntu/<PROJECT_DIRECTORY> &&
git checkout dev &&
git fetch --all &&
git reset --hard origin/dev &&
git pull origin dev &&
sudo npm i &&
sudo npm run build &&
sudo pm2 stop ./dist/index.js &&
sudo pm2 start ./dist/index.js
