篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了OpenShift 3.11离线环境的jenkins演示相关的知识,希望对你有一定的参考价值。

离线安装完成后,一般情况下只装了个基础环境,catalog镜像没有导入,本文主要侧重在jenkins的一些环境设置和演示。

首先follow下面链接下载镜像

https://docs.openshift.com/container-platform/3.11/install/disconnected_install.html

我们这里下载的主要是

$ docker pull registry.redhat.io/openshift3/jenkins-2-rhel7:<tag>

$ docker pull registry.redhat.io/openshift3/jenkins-slave-maven-rhel7:<tag>

$ docker pull registry.redhat.io/openshift3/jenkins-slave-nodejs-rhel7:<tag>

导入到本地镜像仓库

[root@node2 images]# docker images
REPOSITORY                                                   TAG                 IMAGE ID            CREATED             SIZE

registry.example.com/openshift3/jenkins-2-rhel7              latest              0f36706e2c53        10 months ago       1.13 GB
registry.example.com/openshift3/jenkins-slave-maven-rhel7    latest              5ce887d9bf31        11 months ago       1.02 GB
registry.example.com/openshift3/jenkins-slave-nodejs-rhel7   latest              a32c719893f2        11 months ago       971 MB

但现在进入查看jenkins image stream, 发现仍然是不可用状态。

[root@master ~]# oc describe is jenkins -n openshift

执行导入

oc import-image jenkins  --from=registry.example.com/openshift3/jenkins-2-rhel7:latest --confirm --insecure=true

确认导入成功后,在项目中选择Jenkins(Ephemeral),然后等待创建完成。
