Runner安装应用到CI

xuweiqiang大约 3 分钟

1.安装docker

curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun

sudo systemctl start docker

2.登录gitlab获取token

http://localhost:8899/admin/runners

3.安装runner [本地卷]

$ mkdir -p /home/gitlab-runner/config

$ docker run -d --name gitlab-runner --restart always \
  -v /home/gitlab-runner/config:/etc/gitlab-runner \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -v /home/runner:/home/runner \
  gitlab/gitlab-runner:latest
# 注意这里需要填写gitlab地址
# 在docker之中访问宿主机的localhost
# 那么需要执行ifconfig查看网卡docker0的inet地址

$ docker run --rm -it  -v /home/runner:/home/runner -v /home/gitlab-runner/config:/etc/gitlab-runner gitlab/gitlab-runner register
# runner配置注册到gitlab过程

docker run --rm -it -v /home/gitlab-runner/config:/etc/gitlab-runner gitlab/gitlab-runner register

Enter the GitLab instance URL (for example, https://gitlab.com/):
<这里输入gitlab私仓的url>

Enter the registration token:
<这里输入runner的token>

Enter a description for the runner:
[007fa02670d1]: <给这个runner起个名字，会显示在gitlab中>

Enter tags for the runner (comma-separated):
<这里输入tag，跑任务的时候可以通过 tags 来指定>

Registering runner... succeeded runner=rANP_dLs
Enter an executor: docker, docker-ssh, parallels, shell, virtualbox, docker+machine, custom, ssh, docker-ssh+machine, kubernetes:
<运行方式，这里写 docker>

Enter the default Docker image (for example, ruby:2.6):
<默认运行容器，如果在job中不指定容器，默认采用的运行容器，这里我添了 tico/docker>

Runner registered successfully. Feel free to start it, but if it's running already the config should be automatically reloaded!

5.注册成功后在gitlab可以看到runner

http://43.156.75.90:8899/admin/runners

进入docker容器验证可以ping到宿主机的localhost

ifconf

docker exec -it gitlab-runner /bin/bash

apt-get update && apt install iputils-ping

ping $ip

telnet $ip $port

ifconfig的mtu\inet\inet6是什么

在docker容器内如何访问宿主机的localhost

docker.runner register docker runner register x509 insecure registry 问题如何解决

runner 证书问题

runner/install/docker

# 运行一个docker容器
docker run -d --name gitlab-runner --restart always \
  -v /home/gitlab-runner/config:/etc/gitlab-runner \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -v /home/runner:/home/runner \
  gitlab/gitlab-runner:latest

# runner注册到gitlab - 配置的tag要和gitlab.ci.yml的 tag 一致 否则会找不到runner
docker run --rm -it  \
-v /home/runner:/home/runner \
-v /home/gitlab-runner/config:/etc/gitlab-runner \
-v /var/run/docker.sock:/var/run/docker.sock \
gitlab/gitlab-runner register \
--tls-ca-file /home/runner/gitlab.bingosoft.net.crt

[root@master01 config]# cat config.toml

gitlab ci 编写

image: docker:git
services:
  - docker:dind
stages:
  - build
job_build_prod:
  stage: build
  tags:
    - docker-test
  script:
    - docker version

Go的CI的镜像

FROM golang:latest
RUN go install github.com/golangci/golangci-lint/cmd/golangci-lint@v1.49.0
RUN golangci-lint --version

Gitlab的CI编写

  1. 编写.gitlab-ci.yml文件

  2. 通过tags和runner关联

stages:
  - build
  - deploy

image: alpine

build:
  stage: build
  tags :
    - test
  script:
    - echo "build success"

deploy:
  stage: deploy
  tags :
    - test
  script:
    - echo "deploy success"
  1. k8s build && deploy
# 开发环境
build-k8s-develop:
  stage: build-k8s
  tags:
    - ack-runner
  script:
    - make build-k8s-develop
  cache:
    key: go-cache-${CI_PROJECT_PATH_SLUG}
    paths:
      - go/
  only:
    refs:
      - develop
      - /^feature\/.*/
build-k8s-develop: ci/binary Dockerfile
	@docker login -u $(TRI_USER) -p $(TRI_PWD) $(TRI_HOST)
	@docker build -q -t $(DOCKER_IMAGE_DEVELOP):$(DEV_TAG) .
	@docker push $(DOCKER_IMAGE_DEVELOP):$(DEV_TAG)
	@rm $(NAME) Dockerfile
deploy-k8s/develop:
	@cd /builds &&\
	git clone https://$(CI_USERNAME):$(CI_PASSWORD)@git.net/devops/kustomize.git &&\
	cd kustomize/develop/overlays/$(NAME) &&\
	/usr/local/bin/kustomize edit set image default_image=$(DOCKER_IMAGE_DEVELOP):$(DEV_TAG) &&\
	git add . &&\
	git commit -am "update $(PROJECT_NAME) develop kustomize config " &&\
	git pull &&\
	git push origin main || sleep 1 && git pull && git push origin main || echo "nothing to commit" &&\
	echo "xxxx->$(ARGO_HOST)" &&\
	echo y | /usr/local/bin/argocd --grpc-web --insecure login $(ARGO_HOST)  --username $(ARGO_USER) --password $(ARGO_PWD) &&\
	/usr/local/bin/argocd  app sync $(NEW_NAME) || echo "argo sync failed"
