Question

我试图使用docker-compose创建一个postgresql docker容器，但似乎当我使用预先准备好的postgresql映像时，控制台永远不会返回主机，如果我按Ctrl + C容器最终被停止了。这是我得到的：

搬运工-compose.yml

version: '2'
services:
  database:
    container_name: database_server
    build:
      context: .
      dockerfile: Dockerfile_database
    image: database:tag
    expose:
      - "5432"

Dockerfile_database

FROM library/postgres
ADD init.sql /docker-entrypoint-initdb.d/

init.sql

CREATE USER usuario WITH PASSWORD 'senha';
CREATE DATABASE telesaude;
GRANT ALL PRIVILEGES ON DATABASE telesaude TO usuario;

并且在容器创建期间，控制台会显示一些postgresql日志，例如：

Building database

我应该怎么做才能使容器继续运行/启动并且控制台返回主机？ 我必须使用docker-compose。不能使用docker run -d ...

Answer 1

要使用compose在后台运行容器，请使用分离选项：

docker-compose up -d

docker-compose：创建数据库容器
