在Ubuntu上安装OpenShift并使用（）

　　本篇文章为你整理了在Ubuntu上安装OpenShift并使用（）的详细内容，包含有在Ubuntu上安装OpenShift并使用，希望能帮助你了解在Ubuntu上安装OpenShift并使用。

　　服务器信息

　　在阿里云买了个抢占式的服务器，地区为华南广州，系统为Ubuntu 20.04，8核16GB。

　　安装Docker

　　命令如下：

$ apt-get update -y

　　$ apt-get upgrade -y

　　$ apt-get install -y docker.io

　　安装成功后，检查一下版本：

$ docker version

　　Client:

　　 Version: 20.10.7

　　 API version: 1.41

　　 Go version: go1.13.8

　　 Git commit: 20.10.7-0ubuntu5~20.04.2

　　 Built: Mon Nov 1 00:34:17 2021

　　 OS/Arch: linux/amd64

　　 Context: default

　　 Experimental: true

　　Server:

　　 Engine:

　　 Version: 20.10.7

　　 API version: 1.41 (minimum version 1.12)

　　 Go version: go1.13.8

　　 Git commit: 20.10.7-0ubuntu5~20.04.2

　　 Built: Fri Oct 22 00:45:53 2021

　　 OS/Arch: linux/amd64

　　 Experimental: false

　　 containerd:

　　 Version: 1.5.5-0ubuntu3~20.04.1

　　 runc:

　　 Version: 1.0.1-0ubuntu2~20.04.1

　　 GitCommit:

　　 docker-init:

　　 Version: 0.19.0

　　 GitCommit:

　　要修改Docker配置文件，让它可以使用私有的registry：

cat EOF sudo tee /etc/docker/daemon.json

　　 "insecure-registries" : [ "172.30.0.0/16" ]

　　然后重启一下Docker即可：

systemctl restart docker

　　安装OpenShift

　　下载并解压对应的可执行文件：

# 下载

　　$ wget https://github.com/openshift/origin/releases/download/v3.11.0/openshift-origin-client-tools-v3.11.0-0cbc58b-linux-64bit.tar.gz

　　$ tar xvf openshift-origin-client-tools-v3.11.0-0cbc58b-linux-64bit.tar.gz

　　# 复制到bin目录

　　$ cp openshift-origin-client-tools-v3.11.0-0cbc58b-linux-64bit/oc /usr/local/bin/

　　$ cp openshift-origin-client-tools-v3.11.0-0cbc58b-linux-64bit/kubectl /usr/local/bin/

　　# 检查版本

　　$ oc version

　　oc v3.11.0+0cbc58b

　　kubernetes v1.11.0+d4cacc0

　　features: Basic-Auth GSSAPI Kerberos SPNEGO

　　启动集群，第一次需要比较长的时候，因为需要下载镜像：

$ oc cluster up

　　访问Dashboard

　　地址为：https://8.134.68.154:8443/console

　　但是访问会失败，会重定向到127.0.0.1，解决方案如下：

$ oc cluster down

　　$ rm -rf ./openshift.local.clusterup/

　　$ oc cluster up --public-hostname=8.134.68.154

　　重启后，再访问就可以了。

　　oc常用命令

# 登陆

　　oc login -u system -p admin https://8.134.68.154:8443

　　oc login -u developer -p pkslow https://8.134.68.154:8443

　　oc login -u= username -p= password --server= your-openshift-server --insecure-skip-tls-verify

　　# 切换project

　　oc project myproject

　　oc login -n myproject

　　# 创建资源

　　oc create -f myobject.yaml -n myproject

　　oc create configmap propsfilecm --from-file=application.properties

　　oc set volumes dc/myapp --add --overwrite=true --name=configmap-volume --mount-path=/data -t configmap --configmap-name=propsfilecm

　　oc create secret generic oia-secret --from-literal=username=myuser --from-literal=password=mypassword

　　oc set volumes dc/myapp --add --name=secret-volume --mount-path=/opt/app-root/ --secret-name=oia-secret

　　oc patch svc mysvc --type merge --patch {"spec":{"ports":[{"port": 8080, "targetPort": 5000 }]}}

　　# 调试访问

　　oc exec mypod cat /opt/app-root/myapp.config

　　oc rsh mypod

　　oc debug dc mydc

　　oc scale dc mydc --replicas=5

　　oc autoscale dc/app-cli --min 2 --max 5 --cpu-percent=75

　　oc whoami

　　oc status

　　oc logs pod mypod

　　oc get pods --all-namespaces

　　oc describe pod mypod

　　oc get services --sort-by=.metadata.name

　　oc delete all -l app=tomcat

　　oc delete pod mypod --grace-period=0

　　oc export bc,dc,is,svc --as-template=myapp.yaml
