这里记录一下使用docker部署nacos伪集群的过程。
为什么说是伪集群呢？很简单，家里条件没那么富裕，就一台服务器。我在一台服务器上使用docker部署三个nacos服务，所以是伪集群。
一：创建nacos专用网络
docker network create my_network
二：创建数据库nacos

至此，nacos的三集群就已经部署完成了。
但是，有一个小小的问题，docker这个命令有点low。下面我尝试了一下docker-compose.yml

Docker-compose.yml其实很简单，就是将上边的docker命令按照docker-compose的语法写一下即可。

子节点主要关注一下网卡部分即可。one_nacos-network:网卡是上一个docker-compose中创建的。别问我怎么知道的。问就是我查看的。都是坑。
当然，你要是在一个docker-compose中运行三个nacos服务网络设置就使用如下的配置即可：
version: "3.8"
services:
nacos-compose-one:
container_name: nacos-compose-one # 容器名称
networks: # 网络
nacos-network: # 网络
ipv4_address: 172.40.0.2 # ip
nacos-compose-two:
container_name: nacos-compose-two # 容器名称
networks: # 网络
nacos-network: # 网络
ipv4_address: 172.40.0.3 # ip
# 保证nacos集群服务在同一个网段
networks: # 网络
nacos-network: # 网卡名称
ipam: # ipam
driver: default # 驱动：默认
config: # 配置
- subnet: 172.40.0.0/16 # 子网
运行命令：
docker compose up -d
运行成功之后，如下图所示：
以上大概就是docker部署nacos集群的基本流程。有docker命令，还有docker-compose，用那个都可以，看你自己的喜好。
20250428更新：
集群部署如果报错，就换一个IP，比如当前IP是172.40.0.2，启动报错，换成172.40.2.5，可能就不错报错了。
