Getting "Cannot connect to the Docker daemon" while testing Docker image using Docker Stack

Build Environment Running Tests

Hello team,

I am using below cofiguration circle ci to test docker stack.

version: 2
jobs:
  test:
    docker:
      - image: circleci/python:3.7
    steps:
      - checkout
      - run: echo "Initializing build with docker stack
      - run: docker stack deploy -c stack.yml bitroid
      - run: curl localhost
  
  deploy:
    machine:
      enabled: true
    steps:
      - checkout
      - run:
          name: Deploy Master to Heroku
          command: |
            - $HUB_DOCKER_TRIGGER
      
workflows:
  version: 2
  test_and_deploy:
    jobs:
      - test
      - deploy:
          requires:
            - test

It is throwing below error in circle ci .

#!/bin/bash -eo pipefail
docker stack deploy -c stack.yml bitroid
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
Exited with code 1

Can you please check and advice.

Thanks and regards,

Hello team,

After trying hit and trail logic for me this issue is resolved partially with below logic.
I am facing issue from deploy tag.

version: 2
jobs:
  test:
    working_directory: /app
    docker:
      #- image:18.06.0-ce-git
      - image: docker:17.05.0-ce-git
    steps:
      - checkout
      - setup_remote_docker
      - run:
          name: Install dependencies
          command: |
            apk add --no-cache \
              py-pip=9.0.0-r1
            apk --no-cache add curl
            pip install wget
            pip install \
              docker-compose==1.12.0 \
              awscli==1.11.76
      - run: echo "Initializing build with docker stack"
      - run: docker swarm init
      - run: docker stack deploy -c stackfile.yml bitroid
      - run: docker service ls
  
  deploy:
    machine:
      enabled: true
    steps:
      - checkout
      - run:
          name: Deploy Master to Heroku
          command: |
            - $HUB_DOCKER_TRIGGER
      
workflows:
  version: 2
  test_and_deploy:
    jobs:
      - test
      - deploy:
          requires:
            - test

I am getting below error from deploy tag in circle ci.

#!/bin/bash -eo pipefail
- $HUB_DOCKER_TRIGGER
/bin/bash: - : invalid option
Exited with code 1

Can anyone advise urgently,

Thanks,
Hemanth.

Great stuff, I love it when self-fixes are posted :smiley_cat:

I don’t know the purpose of the sleep 90, but that seems like an awfully long time. Can you replace it with a shell script that tests to see if a service is up? I wonder if that would bring the wait time down considerably, while being resilient to unusually slow starts.

I have added sleep time so that service can go to running state within 90 seconds.
