Is the docker daemon running? - Did something change with docker dind services?

I’m having an issue with CI this morning - this ran perfectly fine yesterday -
Here’s what I’ve tried:

  • updated .yml to use docker version 19.03.0 (previously using latest)
  • changed services to use docker:19.03.0-dind ( previously using ‘dind’ - no version )

Runner output:

Here is my .gitlab-ci.yml config:

image: docker:19.03.0

services:
  - docker:19.03.0-dind

stages:
- build

variables:
  DOCKER_DRIVER: overlay2
  DOCKER_TLS_CERTDIR: "/certs"
  CONTAINER_TEST_IMAGE: $CI_REGISTRY_IMAGE:$CI_COMMIT_REF_NAME
  ENVIRONMENT: "prod"

before_script:
  - docker info
  - docker login -u $CI_REGISTRY_USER -p $CI_REGISTRY_PASSWORD $CI_REGISTRY
  - 'echo "Buidling for commit: $CI_COMMIT_REF_NAME"'
  - 'echo "Container test image name: $CONTAINER_TEST_IMAGE"'

build:
  stage: build
  only:
    - tags
    - /^master$/
  script:
    - 'docker build -t $CONTAINER_TEST_IMAGE .'
    - 'docker push $CONTAINER_TEST_IMAGE'

I retried to run the build using a tagged version this time and it worked. Tried again with master and that went fine as well.

This must have been a hick-up in the system.
