What is Skydive
Skydive is an open source real-time network topology and protocols analyzer providing a comprehensive way of understanding what is happening in your network infrastructure.
Skydive是一种开放源码的实时网络拓扑和协议分析器，
它提供了一种全面的方法来理解网络基础设施中正在发生的事情

下面开始在openshift中部署skydive，简单步骤，及过程中需要注意的几个小问题：

环境：openshift是一个master两个node:
大概步骤是，参考链接：https://github.com/skydive-project/skydive/tree/master/contrib/openshift

1.oc new-project skydive
2.oc create -f skydive-template.yaml
3.oc adm policy add-scc-to-user privileged system:serviceaccount:skydive:default
4.oc new-app --template=skydive
5.oc get pods
6.oc get ds
7.oc delete route skydive-analyzer
8.oc expose svc skydive-analyzer

下面详细列述，具体操作过程中需要注意的几点内容：

第一步骤：使用oc命令登录，然后创建项目，执行如下：

[root@master skydive]# oc login
Authentication required for https://master.ose.org:8443 (openshift)
Username: redhat
Password: 
Login successful.You don't have any projects. You can try to create a new project, by runningoc new-project <projectname>[root@master skydive]# oc new-project skydive
Now using project "skydive" on server "https://master.ose.org:8443".You can add applications to this project with the 'new-app' command. For example, try:oc new-app centos/ruby-22-centos7~https://github.com/openshift/ruby-ex.gitto build a new example application in Ruby.
[root@master skydive]# oc get project
NAME      DISPLAY NAME   STATUS
skydive                  Active
[root@master skydive]#

第二步骤：将文件上传openshift master节点服务器某目录下，可以使用sz命令上传或者FileZilla等：

[root@master skydive]# ls
elasticsearch.tar  skydive.tar  skydive-template.yaml

第三步骤：在skydive-template.yaml目录下Install the template

[root@master skydive]# ls
elasticsearch.tar  skydive.tar  skydive-template.yaml
[root@master skydive]# oc create -f skydive-template.yaml
template "skydive" created

第四步骤：使用管理员登录oc login -u system:admin，执行授权：
oc adm policy add-scc-to-user privileged system:serviceaccount:skydive:default

[root@master skydive]# oc login -u system:admin
Logged into "https://master.ose.org:8443" as "system:admin" using existing credentials.You have access to the following projects and can switch between them with 'oc project <projectname>':defaultkube-systemloggingmanagement-infraopenshiftopenshift-infra* skydiveUsing project "skydive".
[root@master skydive]# oc adm policy add-scc-to-user privileged system:serviceaccount:skydive:default

第五步骤：Instanciate the template，实例化模板：

[root@master skydive]# oc new-app --template=skydive
--> Deploying template skydive--> Creating resources with label app=skydive ...service "skydive-analyzer" createddeploymentconfig "skydive-analyzer" createddaemonset "skydive-agent" createdroute "skydive-analyzer" created
--> SuccessRun 'oc status' to view your app.

第六步骤：Check that everything is working and created，检查是否一切正常：

[root@master skydive]# oc get pod
NAME                       READY     STATUS    RESTARTS   AGE
skydive-agent-5sbcj        1/1       Running   0          7m
skydive-agent-67i3k        1/1       Running   0          7m
skydive-agent-w7i07        1/1       Running   0          7m
skydive-analyzer-1-gbwkq   2/2       Running   1          7m

ps: 另外一个问题，镜像处理：
由于我的网络原因，我先将镜像下载，然后上传到服务器，使用命令将它上传到docker，然后push到openshift自己镜像仓库，具体操作如下：

oc import-image registry.ose.org:5000/docker.io/skydive/skydive:latest –confirm –insecure -n openshift

[root@master skydive]# docker load -i skydive.tar
[root@master skydive]# docker load -i elasticsearch.tar
[root@master skydive]# docker tag docker.io/skydive/skydive registry.ose.org:5000/docker.io/skydive/skydive
[root@master skydive]# docker push registry.ose.org:5000/docker.io/skydive/skydive
The push refers to a repository [registry.ose.org:5000/docker.io/skydive/skydive]
918cda4ac29c: Already exists 
7fb731a2e174: Already exists

Pushing tag for rev [ee05e2e60a85] on {http://registry.ose.org:5000/v1/repositories/docker.io/skydive/skydive/tags/latest}
-- 导入到openshift默认的镜像仓库：
[root@master skydive]# oc import-image docker.io/skydive/skydive:latest --confirm --insecure -n openshift
The import completed successfully.Name:                   skydive

大概命令如下：

docker load -i skydive.tar
docker load -i elasticsearch.tardocker tag docker.io/skydive/skydive registry.ose.org:5000/docker.io/skydive/skydive
docker push registry.ose.org:5000/docker.io/skydive/skydive
