我正在使用 postgres 容器作为我的微服务应用程序的一部分。这是我的码头文件：

FROM postgres:alpine
COPY *.sh /docker-entrypoint-initdb.d/

我可以构建此映像并将其发布到我的 azure 映像注册表。我也可以在我的 docker stack yml 文件中使用这个图像：

version: '3.4'

services:
    webserver:
        image: myreg.azurecr.io/webserver:latest
        volumes:
            - /etc/letsencrypt:/etc/letsencrypt
            - /var/lib/letsencrypt:/var/lib/letsencrypt
        ports:
            - 80:80
            - 443:443

    postgres:
        image: myreg.azurecr.io/postgresql:latest
        environment:
            POSTGRES_PASSWORD: my-super-secure-password
        volumes:
            - /data/postgresql:/var/lib/postgresql
            - /data/postgresql/data:/var/lib/postgresql/data

....

但是当我尝试连接到这个容器时，我得到以下日志（来自这个容器）

2018-04-03 10:37:40.836 UTC [1] LOG:  listening on IPv4 address "0.0.0.0", port 5432

但是当我进入这个容器时，docker exec我可以看到我的密码：

$ docker exec -it 7224df929a21 bash
# printenv
PG_SHA256=3ccb4e25fe7a7ea6308dea103cac202963e6b746697366d72ec2900449a5e713
HOSTNAME=7224df929a21
TERM=xterm
PG_MAJOR=10
POSTGRES_PASSWORD=my-super-secure-password
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
PWD=/
LANG=en_US.utf8
SHLVL=1
HOME=/root
PG_VERSION=10.1
PGDATA=/var/lib/postgresql/data
_=/bin/printenv

我在这里做错了什么？
