Jenkins Pipeline 是 Jenkins 提供的一种用于持续集成和持续交付(CI/CD)的脚本化流程工具。它允许你通过编写一个 Jenkinsfile 文件来定义整个构建、测试和部署的流程。本文介绍打包springcloud项目,react项目为docker镜像

}
3.3.执行打包任务
3.4. 导入镜像
下载后执行
tar -xzvf 1.0.0.tar.gz
cd 1.0.0
bash images-load.sh
4. 打包不同架构的基础image
推荐一部分
4.1. java
# x86_64
adoptopenjdk/openjdk8-openj9:alpine-slim
# aarch64
arm64v8/adoptopenjdk:8-jre-openj9
4.2. nginx
# x86_64
nginx:1.26.1-alpine
# aarch64
nginx:1.26.1-alpine
5. 注意
5.1. 拉取http仓库 connect: connection refused"
[ERROR] Failed to execute goal com.spotify:dockerfile-maven-plugin:1.4.13:build (default) on project lhm-eureka: Could not pull cache-from image: Request error: POST unix://localhost:80/images/create?fromImage=192.168.56.10%2Flhm%2Flhm-eureka&tag=x86_641.0.0: 500, body: {"message":"Get https://192.168.56.10/v2/: dial tcp 192.168.56.10:443: connect: connection refused"} -> [Help 1]
解决办法:
设置docker的仓库地址
vi /etc/docker/daemon.json
新增 registry-mirrors:["http://192.168.56.10"],
"insecure-registries" : ["192.168.56.10:5000", "0.0.0.0/0"]
insecure-registries
是Docker中的一个配置选项,涉及容器镜像的安全拉取。
- 定义与用途:
指允许Docker从不安全(即未使用HTTPS协议的)注册中心拉取镜像的列表。默认情况下,Docker为了安全考虑,只允许从使用HTTPS的注册中心拉取镜像。 - 配置方式:
在Docker配置文件(如/etc/docker/daemon.json
)中,通过添加"insecure-registries"
字段并指定一个或多个注册中心地址来配置。例如,"insecure-registries" : ["my-registry.local:5000"]
允许从不安全的my-registry.local:5000
拉取镜像。
5.2. Jenkinsfile Pipeline 打包镜像缓慢解决办法
- 将所有使用的docker镜像推送至自己的私有仓库(防止拉取其他镜像缓慢)
DockerFile 文件
FROM openjdk:8-jdk-alpine as builder
# 执行工作目录
WORKDIR target
上述文件比下面的文件缓慢接近20多倍
FROM 192.168.56.10/lhm/openjdk:8-jdk-alpine
# 执行工作目录
WORKDIR target
5.3. unauthorized to access repository
[ERROR] Failed to execute goal com.spotify:dockerfile-maven-plugin:1.4.13:build (default) on project lhm-eureka: Could not build image: unauthorized: unauthorized to access repository: lhm/openjdk, action: pull: unauthorized to access repository: lhm/openjdk, action: pull -> [Help 1]
解决办法
docker login 192.168.56.10 admin Harbor12345
或者
新增 -v /root/.docker/config.json:/root/.docker/config.json docker{image '192.168.56.10/lhm/maven:3.8-adoptopenjdk-8-openj9'reuseNode trueargs '-v /root/.docker/config.json:/root/.docker/config.json -v /home/jenkins/repository:/root/.m2 -v /var/run/docker.sock:/var/run/docker.sock'
}
6. 打包增量
