Docker 搭建 Jenkins 如何进行升级以及升级遇到的问题记录

我的 Jenkins 是使用 Docker 部署的，部署的脚本如下:

5

8
9
10
11
services:
  jenkins:
    image: 192.168.1.231:6117/jenkins/jenkins:2.531-jdk21
    container_name: jenkins
    restart: always
    volumes:
      - ./data:/var/jenkins_home
    ports:
      - 6108:8080
      #- 50000:50000

升级步骤

总体思路

  1. 直接从 docker hub 上找最新的镜像包，更改 image 的 jenkins 版本重启升级即可

升级问题

绝大部分场景下，更新版本重启后就行了
我这里遇到一个插件问题，例如:

jenkins  | java.io.IOException: Failed to load: Folders Plugin (cloudbees-folder 6.1062.v2877b_d6b_b_eeb_)
jenkins  | [LF]>  - Update required: Credentials Plugin (credentials 1389.vd7a_b_f5fa_50a_2) to be updated to 1447.v4cb_b_539b_5321 or higher

jenkins  |      at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source)
jenkins  |      at java.base/java.lang.Thread.run(Unknown Source)

这里需要 credentials 插件升级到最少 1447.v4cb_b_539b_5321
Jenkins 在升级时会自动升级插件的版本，但有时候会遇到一些问题，这时候需要手动解决

  1. 去 https://plugins.jenkins.io/credentials/releases/ 手动下载插件文件
  2. 将下载下来的 hpi 文件修改后缀名为 jpi, 并且上传到Jenkins的 plugins 目录下， 并且删除同名的解压目录
  3. 重启 Jenkins
  4. 再次观察日志，如有其他插件问题，再重复上面的方式解决

备份问题

我这边是使用 ThinBackup 这个插件的来备份数据的
但是有个问题，就是这个插件安装后在 Jenkins的后台页面上找不到设置的 UI， 只有 Backup now 和 Restore 2 个按钮
后来看插件的文档，（ 注意：从 2.0 版本开始，这些设置存在于全局配置中）
这里是插件文档: https://plugins.jenkins.io/thinBackup/

或者可以直接配置插件的配置文件 org.jvnet.hudson.plugins.thinbackup.ThinBackupPluginImpl.xml
我的配置如下:
