Question

This Content is from Stack Overflow. Question asked by Sathya Molagoda

I’m trying to run docker commands in an ssh connection which was made from github actions. There I’m using even mention in the workflow. Here is my workflow

# This workflow will do a clean installation of node dependencies, cache/restore them, build the source code and run tests across different versions of node
# For more information see: https://help.github.com/actions/language-and-framework-guides/using-nodejs-with-github-actions

name: Node.js CI

on:
  pull_request:
    branches: ['main']

env:
  REGISTRY: 'ghcr.io/testing/api-gateway'
  IMAGE_NAME: ${{ format('{0}-{1}', github.event.repository.name, github.sha) }}
  USERNAME: ${{ secrets.USERNAME }}
  DOCKER_TOKEN: ${{ secrets.DOCKER_TOKEN }}

jobs:
  build:
    runs-on: ubuntu-latest

    strategy:
      matrix:
        node-version: [16.x]

    steps:
      - uses: actions/checkout@v3

      - name: Use Node.js ${{ matrix.node-version }}
        uses: actions/setup-node@v3
        with:
          node-version: ${{ matrix.node-version }}
          cache: 'npm'
      - run: npm install
      - run: npm run build

      - name: Build & Push docker
        run: docker build -t $REGISTRY:$IMAGE_NAME .

      - name: Login to github package repository
        run: echo $DOCKER_TOKEN | docker login ghcr.io -u $USERNAME --password-stdin

      - name: Push docker image
        run: docker push $REGISTRY:$IMAGE_NAME

  deploy:
    runs-on: ubuntu-latest
    needs: build

    steps:
      - name: Deploy to Digital Ocean droplet via SSH action
        uses: garygrossgarten/github-action-ssh@release
        with:
          host: ${{ secrets.DO_HOST }}
          username: ${{ secrets.DO_USER }}
          privateKey: ${{ secrets.DO_KEY }}
          passphrase: ${{ secrets.DO_PASSPHRASE }}
          command: |
            echo $DOCKER_TOKEN | docker login ghcr.io -u $USERNAME --password-stdin
            docker pull $REGISTRY:$IMAGE_NAME
            docker run -p 3000:3000 $REGISTRY:$IMAGE_NAME

But I’m getting the following error when I run the workflow.

I was looking for a solution and I couldn’t find a proper one. what would be the best solution for this?

Solution

According to this other thread about the Cannot perform an interactive login from a non-TTY device message:

docker login prints this error message when you use –password-stdin, but don’t actually send a password to the command’s stdin.

Therefore, it seems the $DOCKER_TOKEN variable is empty.

You could try using ${{ env.DOCKER_TOKEN}}, or add env: DOCKER_TOKEN: ${{ env.DOCKER_TOKEN }} in the last step of your deploy job.

Something like this:

  deploy:
    runs-on: ubuntu-latest
    needs: build

    steps:
      - name: Deploy to Digital Ocean droplet via SSH action
        uses: garygrossgarten/github-action-ssh@release
        env:
          DOCKER_TOKEN: ${{ env.DOCKER_TOKEN }}
        with:
          host: ${{ secrets.DO_HOST }}
          username: ${{ secrets.DO_USER }}
          privateKey: ${{ secrets.DO_KEY }}
          passphrase: ${{ secrets.DO_PASSPHRASE }}
          command: |
            echo $DOCKER_TOKEN | docker login ghcr.io -u $USERNAME --password-stdin 
            # or using directly ${{ env.DOCKER_TOKEN}} instead of $DOCKER_TOKEN
            docker pull $REGISTRY:$IMAGE_NAME
            docker run -p 3000:3000 $REGISTRY:$IMAGE_NAME
