Docker创建Redis集群

docker network create redis --subnet 172.38.0.0/16

for port in $(seq 1 6); \
do \
mkdir -p /root/docker-study/redis/node-${port}/conf
touch /root/docker-study/redis/node-${port}/conf/redis.conf
cat << EOF >>/root/docker-study/redis/node-${port}/conf/redis.conf
port 6379
bind 0.0.0.0
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 5000
cluster-announce-ip 172.38.0.1${port}
cluster-announce-port 6379
cluster-announce-bus-port 16379
appendonly yes
EOF
done

docker run -p 6371:6379 -p 16371:16379 --name redis-1 \
-v /root/docker-study/redis/node-1/data:/data \
-v /root/docker-study/redis/node-1/conf/redis.conf:/etc/redis/redis.conf \
-d --net redis --ip 172.38.0.11 redis:5.0.9-alpine3.11 redis-server /etc/redis/redis.conf

通过脚本配置启动
for port in $(seq 1 6); \
do \
docker run -p 637${port}:6379 -p 1637${port}:16379 --name redis-${port} \
-v /root/docker-study/redis/node-${port}/data:/data \
-v /root/docker-study/redis/node-${port}/conf/redis.conf:/etc/redis/redis.conf \
-d --net redis --ip 172.38.0.1${port} redis:5.0.9-alpine3.11 redis-server /etc/redis/redis.conf 
done

docker exec -it redis-1 sh
创建集群
redis-cli --cluster create 172.38.0.11:6379 172.38.0.12:6379 172.38.0.13:6379 172.38.0.14:6379 172.38.0.15:6379 172.38.0.16:6379 --cluster-replicas 1

docker ps | grep "redis"

批量关闭容器

docker stop $(docker ps | grep "redis" | awk '{print $1}')
docker rm $(docker ps -a | grep "redis" | awk '{print $1}')

删除镜像
docker rmi $(docker images | grep "筛选关键字" | awk '{print $3}')
