docker深入1-使用docker运行nsq
一、在10.0.200.21上测试
首先pull一个nsq的镜像
docker pull nsqio/nsq
二、启动容器
1）运行docker容器lookupd
[root@svr200-21 docker]# docker run -d --name lookupd -p 4160:4160 -p 4161:4161 nsqio/nsq /nsqlookupd
f37732ecb5a667da072bbdb132c0f7d616dca528885202152592267ac2a2cbdc
2）得到容器lookupd所在的docker host的IP地址：
[root@svr200-21 docker]# docker inspect -f '{{ .NetworkSettings.IPAddress }}' lookupd
172.17.0.22
3）运行docker容器nsqd
[root@svr200-21 docker]# docker run -d --name nsqd -p 4150:4150 -p 4151:4151 nsqio/nsq /nsqd --broadcast-address=172.17.0.22 --lookupd-tcp-address=172.17.0.22:4160
181da12ff439e47187a65bb003e45d838d1740ffb0a1bb7adb689df4354e4f9e
4）运行docker容器nsqadmin
[root@svr200-21 docker]# docker run -d --name nsqadmin -p 4171:4171 nsqio/nsq /nsqadmin --lookupd-http-address=172.17.0.22:4161
5cc90923902ce864b5632a4e1a406e4dbd8e4fd092f49b8159d10efa499df9d6
5）开放宿主机10.0.200.21的防火墙
-A INPUT -p tcp -m state --state NEW -m tcp --dport 4150:4151 -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 4160:4161 -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 4171 -j ACCEPT
查看docker容器：
[root@svr200-21 docker]# docker ps -a

通过http://10.0.200.21:4171来访问nsqadmin
