jenkins pipeline打包流程

news 2024/12/17 16:08:34

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

2.项目打包改造

3.3.执行打包任务

在这里插入图片描述

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]

在这里插入图片描述

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

在这里插入图片描述

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'
