OpenShift搭建Kubernetes环境02

1、通过镜像部署应用

#登录,用户名developer密码任意
./oc login -u developer
./oc whoami

#部署应用
#方法1
./oc tag --source=docker openshift/deployment-example:v1 deployment-example:latest
#方法2
./oc tag docker.io/openshift/deployment-example:v1 deployment-example:latest
./oc new-app deployment-example:latest
./oc status
curl http://172.30.192.169:8080

#更新应用
#方法1
./oc tag --source=docker openshift/deployment-example:v2 deployment-example:latest
#方法2
oc tag docker.io/openshift/deployment-example:v2 deployment-example:latest
curl http://172.30.192.169:8080

#查看情况
./oc get all

2、构建镜像并部署应用

#登录
./oc login https://IP:8443 -u developer

#部署应用
./oc new-app openshift/nodejs-010-centos7~https://github.com/sclorg/nodejs-ex.git
--&gt; Found Docker image b3b1ce7 (2 years old) from Docker Hub for "openshift/nodejs-010-centos7"

Node.js 0.10
------------
Platform for building and running Node.js 0.10 applications

Tags: builder, nodejs, nodejs010

* An image stream tag will be created as "nodejs-010-centos7:latest" that will track the source image
* A source build using source code from https://github.com/sclorg/nodejs-ex.git will be created
* The resulting image will be pushed to image stream tag "nodejs-ex:latest"
* Every time "nodejs-010-centos7:latest" changes a new build will be triggered
* This image will be deployed in deployment config "nodejs-ex"
* Port 8080/tcp will be load balanced by service "nodejs-ex"
* Other containers can access this service through the hostname "nodejs-ex"

Build scheduled, use 'oc logs -f bc/nodejs-ex' to track its progress.
Application is not exposed. You can expose services to the outside world by executing one or more of the commands below:
'oc expose svc/nodejs-ex'
Run 'oc status' to view your app.

#暴露服务
./oc expose svc/nodejs-ex

#查看状态
./oc status
