DBeaver / PostgresSQL 无法连接到远程 docker 容器

Question

我正在尝试通过 DBeaver 访问 postgresql docker 容器，但我不知道如何使其工作。

运行docker port db_1返回：

5432/tcp -> 0.0.0.0:5432

所以端口应该对连接开放。

该postgresql.conf设置为

listen_addresses = '*'

运行docker inspect --format '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' db_1返回

172.19.0.2

当试图连接到数据库，要么localhost/ 127.0.0.1/ 172.19.0.2/db_1该Dbeaver日志返回此：

关于如何使连接工作真的一无所知。SSH 隧道显然有效，但与数据库的连接失败。我有一个在另一个容器中运行的 spring 启动应用程序，通过连接字符串连接它jdbc:postgresql://db_1:5432/test就像一个魅力。

对此有任何意见吗？难道它0.0.0.0没有以某种方式映射到内部网络？

Answer 1

您究竟是如何运行容器的，我怀疑您可能缺少公开端口？因为我刚刚尝试在 PS 中使用以下命令运行 postgres 实例：

docker run --name some-postgres -e POSTGRES_PASSWORD=mysecretpassword -d -p 5433:5432 postgres

将默认的 postgres 容器端口 5432 映射到我的本地 5433 端口（因为我在本地安装了 postgres，并且不想遇到某种端口干扰问题），然后通过访问 docker 并运行一些 psql 创建了一个数据库命令如本答案所述，然后从 DBeaver 访问数据库

一切都很好！希望这可以帮助。
