OpenShift 简介 Overview 02

因为进度原因, 先把目前在做的更新出来, 之后再补上缺失的内容.

快速搭建一个 OCP 来做测试.

环境: Mac OS X High Sierra

OCP: Latest(3.6.1)

安装过程:

1. 安装 Docker:

　　https://store.docker.com/editions/community/docker-ce-desktop-mac

　　下载, 安装, DMG 格式的, 无脑装就好了, 安装完你能看到小鲸鱼图标, Docker is running

　　

2. 配置 Docker:

　　Preferences > Advanced, 根据你的资源给做配置吧, CPU 2-4, 内存 4-12 GB, 磁盘你可以自己选地方也可以默认

　　

　　

　　Daemon, insecure registries 这里在安装 OCP 的时候会提示你的, 172.30.0.0/16

　　Registry Mirrors 可以填镜像地址, 毕竟 docker.io 太慢了

　　　　

　　应用了重启

3. 安装 oc 命令:

　　https://github.com/openshift/origin/blob/master/docs/cluster_up_down.md

　　我用 homebrew 安装的:

brew install openshift-cli

　

4. 启动 OCP:

MacBook-Pro:~ joshuapu$ oc cluster up
Starting OpenShift using openshift/origin:v3.6.1 ...
OpenShift server started.

The server is accessible via web console at:
    https://127.0.0.1:8443

You are logged in as:
    User:     developer
    Password: <any value>

To login as administrator:
    oc login -u system:admin

好了, OCP 起来了, 接下来我们就可以登录使用了

5. 查看一下系统状态

MacBook-Pro:~ joshuapu$ oc whoami
developer
MacBook-Pro:~ joshuapu$ oc login -u system:admin
Logged into "https://127.0.0.1:8443" as "system:admin" using existing credentials.

You have access to the following projects and can switch between them with 'oc project <projectname>':

    default
    kube-public
    kube-system
  * myproject
    openshift
    openshift-infra

Using project "myproject".
MacBook-Pro:~ joshuapu$ oc project default
Now using project "default" on server "https://127.0.0.1:8443".
MacBook-Pro:~ joshuapu$ oc get pods
