如何解决Jenkins 的存储无法与 Dockerfile 代理同步运行
我一直在努力让 Jenkins 声明的管道存储在 Dockerfile 代理下运行的步骤的结果。各种Dockerfile/stash配置后,继续失败。希望有人能指出我的错误。
以下是 Jenkins 文件的精简版,失败的方式与原始文件相同。
詹金斯文件:
pipeline {
agent {
label 'Docker-enabled'
}
stages {
stage('Build') {
agent {
dockerfile {
filename 'cicd/docker/light.Dockerfile'
label 'Docker-enabled'
args '--user root'
}
}
steps {
script {
sh """
echo "hello" > /hi.txt
chmod 666 /hi.txt
chown jenkins:jenkins /hi.txt
"""
dir("/") {
stash name: "TARGET",includes: "hi.txt"
}
}
}
}
stage('Test'){
steps {
script {
echo "test"
}
}
}
}
}
它引用的 dockerfile 基于 dotnet/sdk:5.0-alpine 基础镜像。

我知道使用 Dockerfile 代理很简单,但我无法弄清楚它是什么,因此我们将不胜感激。
提前致谢。
解决方法
我将输出从根目录更改为 Docker 容器中 root 的子目录,以便将输出写入 /out/hi.txt
。接下来,我将卷挂载添加到 Dockerfile args 参数 args '--user root -v /tmp:/out'
。最后,我修改了 stash 命令以从 /tmp
目录加载文件,该目录与容器内的 /out
目录共享。
完成这些更改后,stash
命令可以在 /tmp
目录中找到该文件并将其保存以供后续步骤使用。

agent {
dockerfile {
filename 'cicd/docker/light.Dockerfile'
label 'Docker-enabled'
args '--user root -v /tmp:/out'
}
}
steps {
script {
sh """
mkdir /out
echo "hello" > /out/hi.txt
chmod 666 /out/hi.txt
chown jenkins:jenkins /out/hi.txt
"""
dir("/tmp") {
stash name: "TARGET",includes: "**"
}
}
}
}
