# 启动节点
docker stack deploy -c redis.yml redis-cluster

# 搭建集群(自动拼接端口的方式)
docker exec -it $(docker ps -qf "name=redis-cluster_redis1.1") redis-cli --cluster create $(for index in {1..6}; do echo "10.0.16.17:700${index}"; done) --cluster-replicas 1 -a foobared

# 查看集群是否健康
docker exec -it $(docker ps -qf "name=redis-cluster_redis1.1") redis-cli -p 7001 -a foobared cluster info

### 测试执行命令
docker exec -it $(docker ps -qf "name=redis-cluster_redis1.1") redis-cli -c -p 7001 -a foobared info Replication

• Auto-input yes

# 自动拼接并输入yes执行命令

# 方式一
yes yes | docker exec -i $(docker ps -qf "name=rds-cluster_redis1.1") redis-cli --cluster create $(docker inspect -f '{{.NetworkSettings.Networks.middleware.IPAddress}}:{{range $p, $conf := .NetworkSettings.Ports}}{{if eq (index (split $p "/") 0 | printf "%.3s") "800"}}{{(index (split $p "/") 0)}}{{end}}{{end}}' $(docker ps -qf "name=rds-cluster_redis")) --cluster-replicas 0 -a foobared

# 方式二
docker exec -i $(docker ps -qf "name=rds-cluster_redis1.1") redis-cli --cluster create $(docker inspect -f '{{.NetworkSettings.Networks.middleware.IPAddress}}:{{range $p, $conf := .NetworkSettings.Ports}}{{if eq (index (split $p "/") 0 | printf "%.3s") "800"}}{{(index (split $p "/") 0)}}{{end}}{{end}}' $(docker ps -qf "name=rds-cluster_redis")) --cluster-replicas 0 -a foobared << EOF

• Delete volume of the specified prefix
  • grep -o arguments for matching string only
  • The xargs' -r argument is that the xargs command will not execute the next command if no arguments are entered

docker volume | grep -o "redis-cluster.*" | xargs -r docker volume
