使用docker获取rancher
[root@localhost /]# docker pull rancher/server:stable [root@localhost /]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE docker.io/hongdada/docker-centos latest bd4403c66e5e 11 hours ago 595 MB docker.io/nginx latest 5699ececb21c 9 days ago 109 MB docker.io/ubuntu 16.04 5e8b97a2a082 4 weeks ago 114 MB docker.io/rancher/server stable 85b3b338d0be 4 weeks ago 1.08 GB docker.io/tomcat latest 33e02377a00f 2 months ago 554 MB docker.io/centos 7.2.1511 0a2bad7da9b5 8 months ago 195 MB
可以看出rancher体积还是比较大的，有1个G
安装：
[root@localhost /]# docker run -d --restart=unless-stopped -p 8888:8080 rancher/server:stable 405098f5d97988758134da5d3f5c755c8745838a15777034721eed72c94d6a02 [root@localhost /]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 405098f5d979 rancher/server:stable "/usr/bin/entry /u..." 7 seconds ago Up 4 seconds 3306/tcp, 0.0.0.0:8888->8080/tcp relaxed_wescoff
按照上面的，打开对应的8888端口就可以访问到rancher页面
添加主机：
我本地是使用的虚拟机，重新克隆了一份，新主机ip为192.168.52.128
再次查看主机内部的docker:
[root@localhost hongdada]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE docker.io/hongdada/docker-centos latest bd4403c66e5e 13 hours ago 595 MB docker.io/nginx latest 5699ececb21c 9 days ago 109 MB docker.io/ubuntu 16.04 5e8b97a2a082 4 weeks ago 114 MB docker.io/rancher/net v0.13.13 5a271da7cb72 8 weeks ago 310 MB docker.io/tomcat latest 33e02377a00f 2 months ago 554 MB docker.io/rancher/agent v1.2.10 6023e1a77132 3 months ago 237 MB docker.io/rancher/dns v0.17.3 af151d7fa0e8 3 months ago 243 MB docker.io/rancher/healthcheck v0.3.6 db2d1e6261f3 3 months ago 385 MB docker.io/rancher/metadata v0.10.2 77299bd2078e 5 months ago 245 MB docker.io/rancher/network-manager v0.7.20 eaf2cdb14863 5 months ago 256 MB docker.io/rancher/scheduler v0.8.3 3e640a41799a 6 months ago 242 MB docker.io/centos 7.2.1511 0a2bad7da9b5 8 months ago 195 MB docker.io/rancher/net holder 665d9f6e8cc1 15 months ago 267 MB [root@localhost hongdada]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES f8cc8d905ac9 rancher/healthcheck:v0.3.6 "/.r/r /rancher-en..." 3 minutes ago Up 3 minutes r-healthcheck-healthcheck-1-a09c6e05 a7c07c0070bb rancher/dns:v0.17.3 "/rancher-entrypoi..." 3 minutes ago Up 3 minutes r-network-services-metadata-dns-1-a2ed7714 9f8e9029dcab rancher/net:v0.13.13 "/rancher-entrypoi..." 3 minutes ago Up 3 minutes r-ipsec-ipsec-router-1-fb306133 a7cc7b763c35 rancher/net:v0.13.13 "/rancher-entrypoi..." 3 minutes ago Up 3 minutes r-ipsec-ipsec-connectivity-check-1-a26c3db5 0c09403c3624 rancher/net:holder "/.r/r /rancher-en..." 3 minutes ago Up 3 minutes r-ipsec-ipsec-1-b6e2afbc 13245a558e41 rancher/network-manager:v0.7.20 "/rancher-entrypoi..." 3 minutes ago Up 3 minutes r-network-services-network-manager-1-852edd6d 29ba06f2fa7e rancher/metadata:v0.10.2 "/rancher-entrypoi..." 3 minutes ago Up 3 minutes r-network-services-metadata-1-5469cf59 460c27a70adf rancher/net:v0.13.13 "/rancher-entrypoi..." 3 minutes ago Up 3 minutes r-ipsec-cni-driver-1-2d61af01 3bc6a13a6467 rancher/scheduler:v0.8.3 "/.r/r /rancher-en..." 3 minutes ago Up 3 minutes r-scheduler-scheduler-1-e4962c96 2d9171735c9c rancher/agent:v1.2.10 "/run.sh run" 4 minutes ago Up 4 minutes rancher-agent
发现添加主机以后，rancher会自动添加很多容器
创建容器：
查看主机：（只显示redis的）
[root@localhost hongdada]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE docker.io/redis latest 71a81cb279e3 9 days ago 83.4 MB [root@localhost hongdada]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 17fdb5686e39 redis "/.r/r docker-entr..." 51 seconds ago Up 50 seconds r-redis-2-6e9bf620
使用Redis Desktop Manager连接192.168.52.128:6379,连接成功！
容器界面：
Kubernetes环境：
在Rancher的环境管理中添加Kubernetes环境，并添加对应主机
打开Kubernetes的ui界面
再次查看对应主机的镜像和容器
添加了很多Kubernetes的系统镜像，系统容器
