配置好数据库，选择postgres13.4

version: '3' services:
postgres14.3:
container_name: "postgres14.3"
image: postgres:14.3
volumes:
- /workspace/docker_folder2/postgres14.3:/var/lib/postgresql/data
command: 'tail -F /dev/null'
# command: 'postgres'
ports:
- "5532:5432"
stdin_open: true
tty: true
environment:  #这些内容仅在第一次创建docker的时候有用
- POSTGRES_DB=postgres
- POSTGRES_USER=postgres
- POSTGRES_PASSWORD=88888888

sudo docker-compose up

在运行docker连接数据库的过程，出现报错

首先使用命令export DOCKER_DEFAULT_PLATFORM=linux/amd64

然后执行sudo docker-compose up

会出现同样的报错，查看配置文件，进行command的注释，把command进行替换注释，就可以了

sudo docker-compose up
