First GitLab CI - NodeJS example
Select Project -> Set up CI
Add a .gitlab-ci.yml file to the root directory of your repository, and configure your GitLab project to use a Runner, then each commit or push, triggers your CI pipeline.
This is a .gitlab-ci.yml example.
image: node:8
cache:
paths:
- node_modules/
stages:
- test
test_job1:
stage: test
script:
- npm install
- node ./index.js
tags:
- docker
You can see pipeline job is started when you push your code. But it is pending.
Configuring a Runner: Kubernetes executor
Set URL and token on your ConfigMap YAML file
ConfigMap:
apiVersion: v1
kind: ConfigMap
metadata:
name: gitlab-runner
namespace: gitlab-registry
data:
config.toml: |
concurrent = 4
[[runners]]
name = "Kubernetes Runner"
url = "*********"
token = "*********"
executor = "kubernetes"
[runners.kubernetes]
namespace = "gitlab-registry"
image = "node:8"
Kubernetes auto-deployments
apiVersion: extensions/v1beta1
kind: Deployment
metadata:
name: gitlab-runner
namespace: gitlab-registry
spec:
replicas: 1
selector:

containers:

volumeMounts:

volumes:

persistentVolumeClaim:

Issue: We get the logs from officials YAML file.
Starting multi-runner from /etc/gitlab-runner/config.toml ... builds=0
Running in system-mode.

How to fix?
It is fixed by https://gitlab.com/gitlab-org/gitlab-runner/issues/2002. That is modified deployment yaml and remove ConfigMap.
