1、Jenkins系统配置
选择系统管理
选择系统配置
填写SSH remote hosts
注意，Credentials这里选择的，需要先在凭据那里添加全局凭据
填写新的全局凭据如下：
2、Jenkins上的工程部署配置
新建一个任务
任务类型配置为流水线
任务配置如下：
General这里的配置如图：
构建触发器这里选择第三项
注意，构建触发器这里选择的第三项后面的网址是需要在gitlab这边做配置，才能够从gitlab那边勾到代码自动部署。
同时，需要点击高级按钮，获取里面的Secret token。通过点击Generate按钮。如下图：
高级项目选项不用配置
流水线配置如下：
3、代码配置
需要在工程中配置一个Jenkinsfile-slwdev文件
示例如下：
node{
def mvnHome = tool ‘m3’
def dockerComposeHome = ‘/usr/local/bin’
env.PATH = “
e
n
v
.
P
A
T
H
:
{env.PATH}:
env.PATH:{mvnHome}/bin:${dockerComposeHome}”
def SPRING_PROFILES_ACTIVE = “slwdev”
def API_PORT=8098
def DPORT=18098
def remote=[:]
remote.name=‘[email protected]’
remote.host = ‘10.10.201.96’
remote.user = ‘root’
remote.password = ‘Sutpcslw1’
remote.allowAnyHosts = true
stage(‘Prepare’){
echo “1.Prepare”
checkout scm
pom = readMavenPom file: ‘code/carroad-api/pom.xml’
docker_host = “nexus.sutpc.cc:9091”
img_name = “

}
其中SPRING_PROFILES_ACTIVE是你的分支配置名称
同时，你需要有一个Dockerfile文件
示例如下：
FROM openjdk:8-jdk-alpine
RUN echo “Asia/Shanghai” > /etc/timezone
ADD target/carroad-api-1.0-SNAPSHOT.jar /app/carroad-api.jar
#CMD [“java”, “-jar”,"-Dspring.profiles.active=${SPRING_PROFILES_ACTIVE}", “/app/carroad-api.jar”, “–user.timezone=GMT+08”]
ENTRYPOINT [“sh”,"-c",“java

EXPOSE 8098
注：
Jenkins在打包到docker镜像中时需要能够访问到docker仓库，所以需要在/etc/docker/文件夹下配置一个daemon.json文件。
daemon.json文件内容如下：
{
“registry-mirrors”: [“https://docker.mirrors.ustc.edu.cn”],
“insecure-registries”: [“nexus.sutpc.cc:9091”]
}
至此，整个流程结束。over。
