相关操作
下载镜像
docker pull seataio/seata-server
创建容器
docker run --name seata-server -p 8091:8091 seataio/seata-server
seata-server 环境变量（均为可选）
seata_ip：指定启动ip
seata_port：指定seata-server启动端口，默认为8091
store_mode：seata-server日志存储模式，可为file、db，默认为file
server_node：seata-server节点id，默认为1
seata_env：运行环境，dev、test，如指定dev，启动时会使用registry-dev.conf文件
seata_config_name：配置文件名称，如seata_config_name=file:/root/registry，启动时加载root/registry.conf
************************
使用consul 做注册、配置中心，db存储日志
配置文件：registry.conf
registry {
# file 、nacos 、eureka、redis、zk、consul、etcd3、sofa
type = "consul"
consul {
cluster = "default"
serverAddr = "192.168.57.21:8500"

config {
# file、nacos 、apollo、zk、consul、etcd3
type = "consul"
consul {
serverAddr = "192.168.57.21:8500"
}
}
