GitLab之Runner注册K8S

获取gitlab token Setting->CI/CID Settings界面

需要借助helm完成

#添加源
helm repo add gitlab https://charts.gitlab.io

或者直接拉官网一个yaml

https://gitlab.com/gitlab-org/charts/gitlab-runner/blob/main/values.yaml

修改后如下:

egrep -v "#" gitlab-runn.yaml | grep -v "^$"

imagePullPolicy: IfNotPresent
#gitlab服务器地址
gitlabUrl: http://192.168.10.9/
#runner注册token
runnerRegistrationToken: "mNaxzsqyxpwQQCxJkSTa"
#当停止管道时等待其他作业终止时间

#最大并发作业数量
concurrent: 10
#新作业检查时隔
checkInterval: 30

重要参数列表

gitlabUrl	http://192.168.10.9/
runnerRegistrationToken	runner注册toke
terminationGracePeriodSeconds:	当停止管道时等待其他作业终止时间: 3600
concurrent:	最大并发作业数量 10
checkInterval:	新作业检查时隔 30
executor	执行器类型 : kubernetes
locked	是否锁定 false
tags	你的"k8s-runner,k8s"
runUntagged	是否运行没有标签的项目 true
privileged	开启docker in docker

个人比较喜欢yaml类型的，所以我生成yaml文件执行

helm template --namespace gitlab  gitlab-runner -f gitlab-runn.yaml gitlab/gitlab-runner > runner-manifest.yaml
#执行
kubectl -n gitlab apply -f runner-manifest.yaml

最后配置连接k8s的api

1 设置全局变量 2 在左侧导航栏中，选择Settings > CI / CD。 3 单击Variables右侧的Expand。添加GitLab Runner可用的环境变量。本示例中，添加以下三个变量。

REGISTRY_USERNAME：镜像仓库用户名。

REGISTRY_PASSWORD：镜像仓库密码。

kube_config：KubeConfig的编码字符串。

执行以下命令生成KubeConfig的编码字符串

echo $(cat ~/.kube/config | base64) | tr -d " "

应用部署阶段

deploy:
  tags:
    - k8s
  #image: rancher/kubectl:v1.23.3
  image: registry.cn-hangzhou.aliyuncs.com/haoshuwei24/kubectl:1.16.6
  stage: deploy
  script:
    - mkdir -p /etc/deploy
    - echo $kube_config |base64 -d > $KUBEConFIG
    - kubectl  get pods -n gitlab

完成yaml

services:
  - docker:19.03.7-dind
  - golang:1.17.8-alpine3.15
  - docker:stable
stages:
  - package
  - build and push docker image
  - deploy
variables:
  KUBECONFIG: /etc/deploy/config
build:
  tags:
    - k8s
  image: golang:1.17.8-alpine3.15
  stage: package
    # 只作用在main分支
  only:
    - main
  script:
    - export GO111MODULE=on
    - export GOPROXY=https://goproxy.cn
    - go mod init app
    - go mod tidy
    - go build .
docker build:
  tags:
    - k8s
  variables:
    DOCKER_HOST: tcp://0.0.0.0:2375
    DOCKER_TLS_CERTDIR: ""

  image: docker:stable
  stage: build and push docker image
  # 只作用在main分支
  only:
    - main
  script:
    - docker build -t test:v01 .

deploy:
  tags:
    - k8s
  #image: rancher/kubectl:v1.23.3
  image: registry.cn-hangzhou.aliyuncs.com/haoshuwei24/kubectl:1.16.6
  stage: deploy

  script:
    - mkdir -p /etc/deploy
    - echo $kube_config |base64 -d > $KUBEConFIG
    - kubectl  get pods -n gitlab
