Ant在Docker容器中无法与Jenkins一起使用 [英] Ant not working with Jenkins within a Docker container

问题描述

我想将我的Jenkins CI放在Docker容器中.

I want to have my Jenkins CI in a Docker container.

我已经提取了Jenkins Docker映像并启动了遵循文档:

I've pulled the Jenkins Docker image and started it following the documentation:

sudo docker run -p 8080:8080 -p 50000:50000 -v /var/jenkins_home:/var/jenkins_home jenkins

Jenkins可以正常启动，我使用Ant作为构建工具为项目配置作业.

Jenkins is started okay, I configure the job for the project using Ant as build tool.

运行作业时，Jenkins会针对Ant(与配置的构建目标无关)抛出以下错误:

When I run the job, Jenkins throws the following error regarding to Ant (regardless the configured build target):

错误:命令执行失败.也许您需要将作业配置为 选择其中一种Ant安装程序?

ERROR: command execution failed.Maybe you need to configure the job to choose one of your Ant installations?

但是，如果我转到内部版本(/var/jenkins_home/workspace/my_job/)的工作区目录并执行相同的目标，则不会出错:

But, if I go to the workspace directory of the build (/var/jenkins_home/workspace/my_job/) and execute the same target, I get no error:

ant clean

我在做什么错了?

推荐答案

正如@izzekil指出的那样，Ant并未安装在容器内，而仅安装在主机内.

As @izzekil has pointed, Ant was not installed inside the container, but only in the host machine.

足以在容器中安装Ant(以root用户身份运行):

It has been enough to install Ant in the container (running with root user):

sudo docker run -p 8080:8080 -p 50000:50000 -v /var/jenkins_home:/var/jenkins_home -u root jenkins

然后:

sudo docker exec <container_id> apt-get update
sudo docker exec <container_id> apt-get install ant -y
