docker 配https registry私有倉庫的重點說明
生成ca 證書給harbor 使用

openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout ./server.key -out ./server.crt -subj "/CN=registry.lotbrick.com"

copydocker 客戶端登入harbor 前導入自制Ca 證書位置 mkdir -p /etc/docker/certs.d/registry.lotbrick.com #registry.lotbrick.com 建立域名目錄 node

mkdir -p /etc/docker/certs.d/registry.lotbrick.com

scp ./server.crt  /etc/docker/certs.d/registry.lotbrick.com/ca.crt

systemctl daemon-reload
systemctl restart docker
docker login registry.lotbrick.com

安裝Jenkins

yum install -y python-pip
pip install docker-compose

cd $HOME && mkdir jenkins && cd jenkins
wget https://raw.githubusercontent.com/JyBigBoss/docker-compose/master/jenkins/Dockerfile
wget https://raw.githubusercontent.com/JyBigBoss/docker-compose/master/jenkins/docker-compose.yaml

docker-compose up -d

Jenkins須要安裝的插件

Gitlab Hook、Build Authorization Token Root、Publish Over SSH、Gitlab Authentication
Gitlab、Git Parameter、Git Tag Message、Pipeline、docker-build-step、Docker Pipeline

建立git倉庫

在web頁面建立一個test倉庫，並在在倉庫中新建一個index.html文件

cd $HOME
git clone git@192.168.0.10:yfg/test.git
cd test/
cat << EOF > index.html
<h1>Test 123</h1>
EOF
git add .
git commit -m 'add index.html'
git push

#建立兩個tag
git tag v1 -m 'version:1'
git push --tags
git tag v2 -m 'version:2'
git push --tags

在Harbor上建立一個test倉庫

配置Jenkins

打開Jenkins的設置頁面，配置Publish over SSH插件
建立一個流水線(pipeline)項目

node {
  stage(' Git clone ') {
      git branch: 'master', credentialsId: 'a4a81561-8bc0-426e-89f9-b4d4aa1925d6', url: 'git@192.168.0.10:yfg/test.git'
      env.check_to_tag="$TAG"
      sh '[ -n "${check_to_tag}" ] &&  git checkout ${check_to_tag} ||  { echo -e "切換至指定的tag的版本，tag：${check_to_tag} 不存在或爲空，請檢查輸入的tag!" && exit 111; }'
  }
  stage("Create Dockerfile"){
      sh '''cat << EOF > Dockerfile
FROM python:3.7.1-alpine
RUN mkdir /test
WORKDIR /test
COPY ./ /test
EXPOSE 8000
CMD ["python","-m","http.server"]
EOF'''
      sh 'cat Dockerfile'
  }
  stage("Create docker-compose.yaml "){
      sh '''cat << EOF > docker-compose.yaml
version: "2.4"
services:
http:
  image: registry.lotbrick.com/test/http:${check_to_tag}
  container_name: python-http_server
  ports:
    - "80:8000"
  restart: always
EOF'''

      sh 'cat docker-compose.yaml'
  }

  stage('Build Image And Push to registry') {
    //withRegistry('倉庫地址','jenkins憑據ID')
    docker.withRegistry('https://registry.lotbrick.com', '9ffa7ef5-38c6-49da-8936-ec596359be56'){
        //build當前目錄(workspace)下的Dockerfile
        def BuildImage = docker.build("registry.lotbrick.com/test/http:${check_to_tag}")
        //Push剛纔Build出來的鏡像
        BuildImage.push()
      }
}
stage('Depoly'){
    //調用Publish Over SSH插件，上傳docker-compose.yaml文件而且執行deploy腳本
      sshPublisher(publishers: [sshPublisherDesc(configName: 'jenkins_pipeline_test_deploy', transfers: [sshTransfer(cleanRemote: false, excludes: '', execCommand: '/bin/bash /root/deploy/deploy.sh', execTimeout: 120000, flatten: false, makeEmptyDirs: false, noDefaultExcludes: false, patternSeparator: '[, ]+', remoteDirectory: '/root/deploy', remoteDirectorySDF: false, removePrefix: '', sourceFiles: 'docker-compose.yaml')], usePromotionTimestamp: false, useWorkspaceInPromotion: false, verbose: false)])

}
}

生成流水線腳本的方法

python
Jenkins憑據ID獲取方法

linux
發佈腳本：depoly.sh：放到要部署代碼的主機的/root/deploy目錄下

  #!/bin/bash
  echo '正在更新版本......'

  cd /root/deploy

  IMAGE_NAME='registry.lotbrick.com/test/http'
  DOCKER_TAG=`awk -F ':' '/.*image/{print $NF}' docker-compose.yaml`

  echo -e "\n"
  docker-compose pull && docker-compose up -d

  if [  "$?" == 0 ];then
      echo '刪除舊的image'
      OLD_IMAGE=`docker images | grep $IMAGE_NAME | awk '{print $2,$3}' | grep -v "${DOCKER_TAG}" |awk '{print $1}'`
      for i in $OLD_IMAGE;do
          docker rmi http:$i
      done
  else
     echo "更新版本失敗！！！"
     exit 111
  fi

測試發佈

第一次發佈

再來一次

#感受沒玩夠，再傳個代碼測試一回 cd $HOME git clone https://github.com/HFIProgramming/mikutap.git \cp -r mikutap/* test/ cd test git add . git commit -m 'add mikutap page' git tag v3 -m 'add mikutap page' git push --tags
