当容器启动时使用与 docker 运行
相同的图像，Postgres 似乎工作正常
docker run --name local-postgres9.5 -p 5432:5432 postgres:9.5

无论如何，对于我的项目，我使用另一个 postgresql 图像：https://github.com/sameersbn/docker-postgresql。这个很好用。
如果您查看日志输出，将在末尾显示以下行：

显然，停止并重新启动 Postgres 服务器是初始化过程的一部分。事实上，倒数第二行说

在 docker-compose.yml 中的 postgres 服务下添加密码，如屏幕截图所示。谢谢你。

我使用的是与您 (9.5) 相同的 Postgres docker 图像版本，我 运行 遇到了同样的问题。
第一次创建容器时，Postgres 运行 一系列命令，最后，它只是发送一个关闭信号，服务器变得无响应（但第二次开始工作）。
经过几次尝试，我发现一旦我尝试连接到服务器，在它准备好接受连接之前，PostgresDB 会意外关闭，对于任何尝试远程连接（在容器外）的客户端，都会发生同样的情况。
我在以下情况下遇到此错误 - 我有两个容器：一个用于 PostgresDB 本身，另一个包含尝试连接到第一个容器以创建一些用户的 Postgres 客户端 (psql) 、数据库和 运行 创建所有模式的 liquibase 脚本。
起初，我在 bash 脚本中使用了一个循环，每 5 秒检查一次服务器是否可用，然后在第一次尝试后，Postgres 发出关闭信号并变得无响应。
我可以通过在 docker-compose.yml:
中添加 healthcheck 来消除这个错误

编辑：在 Linux 上使用 Cisco AnyConnect 时，还有另一个问题阻止 Docker 访问受 VPN 保护的站点（甚至互联网站点）（在 MacOS 上不会发生）。为了避免这种不需要的行为，我在 Ubuntu 上安装了 openconnect sudo apt install openconnect 并停止使用 AnyConnect。
希望对您有所帮助！
