我在docker php / postgres / phppgadmin中进行制作，我需要将psql添加到我的项目中以上传我的sql转储。 我找到了这个https://hub.docker.com/r/softwareplant/psql并将其添加到我的项目中，但是运行build命令时出现错误：

docker-compose up -d --build
... 
Sccessfully built 3b0700d7bed8

我的docker-compose.yml：

哪种方法正确？在https://hub.docker.com上有这样的图片... 无效吗？你能建议其他决定吗？

已修改： 接下来，我尝试

https://hub.docker.com/r/governmentpaas/psql
Provides psql Postgres client. 

description seems like what I need : to upload dump into postgres db
In docker-compose.yml I added item :

    psql:
        image: governmentpaas/psql
        environment:
            - PHP_PG_ADMIN_SERVER_HOST=db
            - PHP_PG_ADMIN_SERVER_PORT=5432
            - PHP_PG_ADMIN_SERVER_DEFAULT_DB=postgres
        container_name: lprods_psql

        restart: always
        ports:
            - "8088:80"
            - "444:444"
        links:
            - db

它安装正确，我在托管OS中看到了这个容器：

lprods_docker$ docker ps
CONTAINER ID        IMAGE                       COMMAND                  CREATED             STATUS                          PORTS                                        NAMES

但是进入bash容器时，找不到psql命令：

# uname -a
Linux 7071eaf067d6 4.15.0-66-generic #75-Ubuntu SMP Tue Oct 1 05:24:09 UTC 2019 x86_64 GNU/Linux
root@7071eaf067d6:/var/www/lprods_docker_root# whereis psql

# psql -v
bash: psql: command not found

是我需要的图像吗？如果是，该如何使用？
