与 github 动作和 ec2 混淆

Question

This is my github actions flow:

---
name: build and push image to aws ecr
on:
  push: 
    branches: [ main ]
jobs:
  build-and-push:
    name: Build and push to ecr
    runs-on: ubuntu-latest
    steps:
    - name: Checkout
      uses: actions/checkout@v2
    ...

  deploy:
    needs: build-and-push
    name: deploy
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - name: Login ec2
        env:
          PRIVATE_KEY: ${{ secrets.EC2_SSH_KEY }}
          HOSTNAME: ${{ secrets.HOST_DNS }}
          USER_NAME: ${{ secrets.USERNAME }}
        run: |
          echo "$PRIVATE_KEY" > private_key && chmod 600 private_key
          ssh -o StrictHostKeyChecking=no -i private_key ${USER_NAME}@${HOSTNAME}
          ls
          touch helloworld.txt

I wonder that I'm connected to the EC2 instance or not. This is my result after actions, it's list all file of my project. I think I didn't ssh to EC2 successfull becuase I just create EC2 instance and it's empty.

Run echo "$PRIVATE_KEY" > private_key && chmod 600 private_key

This is my command to ssh ec2 from client: ssh -i "home-key.pem" ec2-user@ec2-18-181-220-91.ap-northeast-1.compute.amazonaws.com

If i didn't connnect to EC2 instance, how I do it with github?

Thanks for your attention.

I wonder that I'm connected to the EC2 instance or not.

In your SSH commands, add a hostname -a one: it will display the name of the machine you are on.

That being said, you could use actions/ssh-execute-commands to execute those same commands:

- name: Execute SSH commmands on remote server
  uses: JimCronqvist/action-ssh@master
  env:
    PRIVATE_KEY: ${{ secrets.EC2_SSH_KEY }}
    HOSTNAME: ${{ secrets.HOST_DNS }}
    USER_NAME: ${{ secrets.USERNAME }}
  with:
    hosts: '${USER_NAME}@${HOSTNAME}'
    privateKey: ${{ secrets.PRIVATE_KEY }}
    debug: false
    command: |
      ls -lah
      hostname -a
      whoami
      touch helloworld.txt
