Question

您好，我是Iam，致力于在Openshift 3.9上实施CICD。我有一个在openshift中运行的詹金斯豆荚。 Iam在jenkins及更低版本中运行Selenium脚本是Iam变得像缺少软件包一样的错误

   Running TestSuite
/var/lib/jenkins/jobs/Pipeline/workspace/src/test/resources/chromedriver: error while loading shared libraries: libgconf-2.so.4: cannot open shared object file: No such file or directory

    at org.openqa.selenium.remote.RemoteWebDriver.startSession(RemoteWebDriver.java:219)

为此，我想通过以下命令在我的jenkins容器中安装libgconf-2-4

yum install libgconf-2-4

当我尝试安装以下内容时，我的jenkins容器中出现以下错误

    sh-4.2$ yum install libgconf2-4
Loaded plugins: ovl, product-id, search-disabled-repos, subscription-manager
[Errno 13] Permission denied: '/etc/pki/entitlement-host'
ovl: Error while doing RPMdb copy-up:
[Errno 13] Permission denied: '/var/lib/rpm/.dbenv.lock'
You need to be root to perform this command.

当我转到指定位置并尝试将权限更改为chmod 777 .dbenv.lock

    sh-4.2$ cd /var/lib/rpm/
sh-4.2$ ls -latr
total 19560
-rw-r--r--. 1 root root        0 Aug  9 18:21 .dbenv.lock

它抛出错误

sh-4.2$ chmod 777 .dbenv.lock
chmod: changing permissions of ‘.dbenv.lock’: Operation not permitted

我的问题是如何以root用户身份进入jenkins pod并通过yum install libgconf-2-4在openshift中安装rpm软件包libgconf-2-4？

Answer 1

似乎您应该按如下方式自定义jenkins图像。[0]

创建Dockerfile。

FROM registry.access.redhat.com/openshift3/jenkins-2-rhel7
USER 0
RUN yum -y install libgconf2-4 && yum clean all -y
USER 1001

使用Dockerfile构建图像。
```
docker build .
```

登录OpenShift的内部注册表以推送图像。

docker login -u admin -p  docker-registry.default.svc:5000

重新标记为OpenShift图片格式和您的标记政策。

docker tag  docker-registry.default.svc:5000/openshift/jenkins-2-rhel7-custom

按下image。

docker push docker-registry.default.svc:5000/openshift/jenkins-2-rhel7-custom

编辑您的deploymentConfig

oc edit dc/jenkins
...
containers:
   ...
   image: "openshift/jenkins-2-rhel7-custom"
   ...

希望它能对您有所帮助。：^）

您可以在您的dockerfile中使用USER root来解决您的问题

以root用户身份使用Openshift容器
