以root用户身份打开shift容器

嗨，我正在openshift 3.9上进行CICD实现。我有一个詹金斯吊舱在露天移动。我在jenkins中运行selenium脚本，下面的错误就像丢失了一个包

Running TestSuite

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

当我尝试安装以下错误时，出现在我的詹金斯容器中

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.

当我到达指定的位置并尝试将权限更改为chmod 777.dbenv.lock 时

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

它作为抛出错误

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jenkinspod，并通过在openshift中安装libgconf-2-4来安装rpm包libgconf-2-4？

您似乎应该自定义jenkins图像，如下所示。[0]

创建Dockerfile。

FROM registry.access.redhat.com/openshift3/jenkins-2-rhel7用户0运行yum-y安装libgconf2-4&&yum-clean-all-y用户1001

使用Dockerfile构建图像。
```
docker构建
```

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

重新标记为OpenShift图像格式和您的标记策略。

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

按下image。

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

编辑您的deploymentConfig

oc编辑dc/jenkins。。。容器：。。。图片："openshift/jenkins-2-rhel7-custom"…

我希望它能帮助你。：^(
