GitLab CI/Docker on Windows/node container - unknown network http

Question

I'm trying to run basic pipeline that should build my web-project using GitLab CI

My setup:

• GitLab CE 10.1.4 on Ubuntu 16.04
• GitLab Runner 10.1.0 on Windows 10 1703 with docker executor
• Docker 17.09.0-ce-win33 (13620) on same Windows machine

.gitlab-ci.yml:

image: node:latest

cache:
  paths:
    - node_modules/

build:
  script:
    - npm install
    - npm run build

And I get failed build with this output:

Running with gitlab-runner 10.1.0 (c1ecf97f)
    on ****** (9366a476)
Using Docker executor with image node:latest ...

ERROR: Job failed (system failure): dial http: unknown network http

I've thought that problem might happen because container can't access internet, but https://hub.docker.com/r/byrnedo/alpine-curl/ curl container got the data, so I think it's not the case.

UPD: Problem occurs when GitLab runner try to attach to container.

Answer 1

Problem was in GitLab CI config (config.toml), docker host.

host = "http://127.0.0.1:2375" - wrong one

should be host = "tcp://127.0.0.1:2375"
