build 镜像
cd /home/postgresql10_docker
docke build -t postgres_10_centos7.6:1.0 .
查看镜像
docker images输出结果：

设置启动端口也为5432
docker run --name pgtest1 -d -p 5431:5432 postgres_10_centos7.6:1.0检查启动的容器
docker ps -a输出如下
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

进入容器查看postgres进程是否正常启动
[root@iZuf678t3hp8rp7xchc3aoZ ~]# docker exec -it 534149dc7726 ps -ef | grep postgres输出结果如下
root 10 1 0 15:53 ? 00:00:00 su - postgres -c /usr/pgsql-10/b

宿主机上查看5432端口是否启动
netstat -nlap | grep 5432输出结果如下
tcp6 0 0 :::5432 :::* LISTEN 22287/docker-proxy
此时一个基于docker的postgresql已经启动成功。
创建docker的volume
docker volume create pgdata_5431
docker volume create pgdata_5433查看volume列表
[root@iZuf678t3hp8rp7xchc3aoZ ~]# docker volume list
DRIVER VOLUME NAME
local pgdata_5431
local pgdata_5433
查看volume的存储位置
[root@iZuf678t3hp8rp7xchc3aoZ postgresql10_docker]# docker inspect pgdata_5431
[
{
"CreatedAt": "2019-11-16T19:23:40+08:00",
"Driver": "local",
"Labels": {},
"Mountpoint": "/var/lib/docker/volumes/pgdata_5431/_data",
"Name": "pgdata_5431",
"Options": {},
"Scope": "local"
}
]
[root@iZuf678t3hp8rp7xchc3aoZ postgresql10_docker]# docker inspect pgdata_5433
[
{
"CreatedAt": "2019-11-16T19:24:38+08:00",

"Labels": {},
"Mountpoint": "/var/lib/docker/volumes/pgdata_5433/_data",
"Name": "pgdata_5433",
"Options": {},
"Scope": "local"
}
]
如果需要将数据盘单独挂载，可以新建个目录mount到分区上，然后将/var/lib/docker/volumes/pgdata_5433目录下的文件移动过来，使用软连接的方式
mkdir /data/pgsql
mv /var/lib/docker/volumes/pgdata_5433 /data/pgsql
ln -s /data/pgsql/pgdata_5433 /var/lib/docker/volumes/pgdata_5433
分别启动两个容器，端口分别为5431，5433
docker run --name pgtest_5431 -d -p 5431:5432 -v pgdata_5431:/var/lib/pgsql/10/data postgres_10_centos7.6:3.0 & disown
docker run --name pgtest_5433 -d -p 5433:5432 -v pgdata_5433:/var/lib/pgsql/10/data postgres_10_centos7.6:3.0 & disown
查看容器启动情况
[root@iZuf678t3hp8rp7xchc3aoZ ~]# docker ps -a

查看宿主机端口
[root@iZuf678t3hp8rp7xchc3aoZ ~]# netstat -nlap | grep 5431

分别进入两个容器，创建超级数据库用户
docker exec -it pgtest_5431 /bin/bash

psql
create user app_user with superuser password 'app_user';
docker exec -it pgtest_5433 /bin/bash
su - postgres
psql
create user app_user with superuser password 'app_user';查看容器的ip
