我使用标准的“image: postgres:13”创建了一个 docker 容器，但是在容器内部它没有启动 postgresql，因为没有集群。可能是什么问题呢？谢谢解答！

version: '3'
services:
    laravel.test:
        build:
            context: ./vendor/laravel/sail/runtimes/8.0
            dockerfile: Dockerfile
            args:
                WWWGROUP: '${WWWGROUP}'
        image: sail-8.0/app
        ports:
            - '${APP_PORT:-80}:80'
        environment:
            WWWUSER: '${WWWUSER}'
            LARAVEL_SAIL: 1
        volumes:
            - '.:/var/www/html'
        networks:
            - sail
        depends_on:
            - pgsql
    pgsql:
        image: 'postgres:13'
        ports:
            - '${FORWARD_DB_PORT:-5432}:5432'
        environment:
            PGPASSWORD: '${DB_PASSWORD:-secret}'
            POSTGRES_DB: '${DB_DATABASE}'
            POSTGRES_USER: '${DB_USERNAME}'
            POSTGRES_PASSWORD: '${DB_PASSWORD:-secret}'
        volumes:
            - 'sailpgsql:/var/lib/postgresql/data'
        networks:
            - sail
        healthcheck:
            test: ["CMD", "pg_isready", "-q", "-d", "${DB_DATABASE}", "-U", "${DB_USERNAME}"]
            retries: 3
            timeout: 5s
networks:
    sail:
        driver: bridge
volumes:
    sailpgsql:
        driver: local

尝试联系容器时出现错误：

SQLSTATE[08006] [7] could not connect to server: Connection refused
    Is the server running on host "localhost" (127.0.0.1) and accepting
    TCP/IP connections on port 5432?

在容器内，当我尝试启动或重新启动 postgres 时，我收到以下消息：

[warn] No PostgreSQL clusters exist; see "man pg_createcluster" ... (warning).

您不应该通过 localhost 连接，而是通过容器名称作为主机名进行连接。

因此，将您的 .env 更改为包含

DB_CONNECTION=[what the name is in the config array]
DB_HOST=pgsql
DB_PORT=5432
DB_DATABASE=laravel
DB_USERNAME=[whatever you want]
DB_PASSWORD=[whatever you want]
