docker部署doris

1：拉取doris镜像的fe和be

docker pull apache/doris:2.0.0_alpha-fe-x86_64

docker pull apache/doris:2.0.0_alpha-be-x86_64

2：拉取成功后的镜像

[root@localhost opt]# docker images
REPOSITORY     TAG                     IMAGE ID       CREATED         SIZE
apache/doris   2.0.0_alpha-be-x86_64   60f47d32355b   14 months ago   5.5GB
apache/doris   2.0.0_alpha-fe-x86_64   d5a47d329bc3   14 months ago   1.35GB

3：必须修改宿主机的环境配置

#临时修改，重启失效
sysctl -w vm.max_map_count=2000000

# 永久修改，添加一行
vim /etc/sysctl.conf
vm.max_map_count=2000000

4：查看系统的建议磁盘空闲大于30G和内存大于4G，不然启动会报内存不足或者磁盘不足之类的

5-1：方法一：通过docker-compose.yml文件，部署一台FE和一台BE(此网络是和宿主机同一个网络，容易出现问题，需要重启docker,才能正常启动，所以建议设置独立的docker网络)

5-2：方法二：通过docker-compose.yml文件，部署一台FE和一台BE(此网络是和宿主机不同网络，创建独立的doker网络，通过nginx来访问)
