gitlab-ci/cd(四)pipeline打包部署java项目

1、拉取代码并上传至gitlab中

[root@docker java-demo]# git clone https://codeup.aliyun.com/613aded82bf07942fbc24954/gani/dev.git
[root@docker java-demo]# cd gitlab-ci-k8s-demo/
[root@docker gitlab-ci-k8s-demo]# git init
[root@docker dev]# git remote add gitlab http://192.168.8.31/root/java-demo.git
[root@docker gitlab-ci-k8s-demo]# git push gitlab master

创建DockerFiles文件

FROM openjdk:8
ENV JAVA_OPTS="$JAVA_OPTS -Dfile.encoding=UTF8 -Duser.timezone=GMT+08"
RUN sed -i 's/dl-cdn.alpinelinux.org/mirrors.aliyun.com/g' /etc/apk/repositories && \
apk add -U tzdata && \
ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
WORKDIR /data/app
COPY ./target/hello.jar .
EXPOSE 80
ENTRYPOINT ["java","-jar","hello.jar"]

修改config.toml文件[因为前面部署挂载到 /data/app/gitlab-runner/config/]

vim /data/app/gitlab-runner/config/config.toml

maven设置settings的方式还可以通过Dockerfile生成一个image。

FROM maven:3.6.2-jdk-14
COPY settings.xml /usr/share/maven/ref/

定义变量

最后一步：执行

备注：rancher方式链接K8S方案参考

思考：这个pipeline中使用cp复制jar包。能否通过artifacts贯穿build和deploy两个步骤呢？
