example gitlab-ci job - Githubissues

arun-prakash-fokus commented 3 years ago

I am trying to use your image to run inside a gitlab-ci job as follows:

stages:
    - test

test_bootstrap_ubuntu-dind:
  # test the bootstrap with DIND
  stage: test
  tags:
    - docker
  image:
    name: cruizba/ubuntu-dind:latest
  services:
    - name: docker:20-dind
      alias: docker    
  before_script:
    - echo "before script"
  script:
    - echo "inside script"
    - ls -l

and get the following console messages:

[Thu Apr  1 21:09:16 UTC 2021] [INFO] [/usr/local/bin/startup.sh] Process dockerd is not running yet. Retrying in 1 seconds
[Thu Apr  1 21:09:16 UTC 2021] [INFO] [/usr/local/bin/startup.sh] Waited 29 seconds of 30 seconds
[Thu Apr  1 21:09:17 UTC 2021] [ERROR]  dockerd is not running after max time

what am doing wrong? do you have any suggestions?

I don't know how gitlab ci works, but this error usually happens if you don't run the container as --privileged. Reminder that this is not secure, but there is no other way to run docker in docker without "extra" features.

Anyways, there are better solutions like this https://github.com/nestybox/sysbox

It works for me in general with an priviledged gitlab-runner and when I run /usr/local/bin/startup.sh in the script section again. Entrypoint might be overwritten as described in GitlabEE Docs

I had also the need for run ubuntu-dind, which is the reason why I landed here by Google search. My constraints are

running bazel on Ubuntu which is not available at Alpine
build docker image, based on Docker in Docker architecture while running in Gitlab Docker runner with an Alpine image. At the end my .gitlab-ci.yml was something like that:

image: docker:dind

variables:
  DOCKER_DRIVER: overlay2
  DOCKER_HOST: tcp://localhost:2375
  DOCKER_TLS_CERTDIR: ''
  DEBIAN_FRONTEND: noninteractive
  BAZEL_VERSION: "4.0.0"

services:
  - name: docker:dind
    alias: docker   

stages:
  - build

build:
  image: ubuntu:20.04
  tags:
    - k8s-executor
  stage: build
  script:
    - echo "install packages"
    - apt-get update && apt-get -y upgrade
    - apt-get install -y -o Dpkg::Options::=--force-confdef -o Dpkg::Options::=--force-confnew bash curl wget git openssl make python3-dev python3-pip gcc g++ docker.io
    - echo "install bazel"
    - wget -q https://github.com/bazelbuild/bazel/releases/download/${BAZEL_VERSION}/bazel-${BAZEL_VERSION}-linux-x86_64
    - chmod +x bazel-${BAZEL_VERSION}-linux-x86_64
    - mv bazel-${BAZEL_VERSION}-linux-x86_64 /usr/local/bin/bazel
    #... doing things with bazel and build an image to push

cruizba / ubuntu-dind
