1.2 创建镜像

erichan@ubuntu14_04_1-pd:~/docker-room/ubuntu-redis$ d build -t feuyeux/redis .

1.3 测试镜像

erichan@ubuntu14_04_1-pd:~/docker-room/ubuntu-redis$ d run -d --name redis -p 6379:6379 feuyeux/redis

redis-cli

d run -ti --rm --link redis:redis feuyeux/redis bash -c 'redis-cli -h $REDIS_PORT_6379_TCP_ADDR'

--rm=false: Automatically remove the container when it exits (incompatible with -d)

2 Master-Slave Cluster

    exit 7;
fi
exec redis-server --slaveof $REDIS_MASTER_PORT_6379_TCP_ADDR $REDIS_MASTER_PORT_6379_TCP_PORT $*

2.2 创建镜像

启动辅

Slave:
d run -d --name=feuyeux_redis_slave -p 6379:6380 --link=feuyeux_redis_master:redis_master feuyeux/redis-slave

调试

d kill $(d ps -a) && d rm $(d ps -a -q)

d build -t feuyeux/redis-slave . && 
d run -d --name feuyeux_redis_master -p 6379:6379 feuyeux/redis && d run -d --name=feuyeux_redis_slave -p 6380:6380 --link=feuyeux_redis_master:redis_master feuyeux/redis-slave && d logs feuyeux_redis_slave

d start feuyeux_redis_slave
d start feuyeux_redis_master

redis-cli

进入主/辅

Cli-Master:
PID=$(d inspect --format {{.State.Pid}} feuyeux_redis_master) && sudo nsenter --target $PID --mount --uts --ipc --net --pid

Cli-Slave:
PID=$(d inspect --format {{.State.Pid}} feuyeux_redis_slave) && sudo nsenter --target $PID --mount --uts --ipc --net --pid
