DBeaver/PostgreSQL无法连接到远程docker容器

Question

5432/tcp -> 0.0.0.0:5432

PostgreSQL L.conf设置为

listen_addresses = '*'

运行Docker检查--格式化“{{range.networksettings.networks}}{{.ipaddress}}{{end}}”db_1返回

172.19.0.2

当尝试将数据库连接到localhost/127.0.0.1/172.19.0.2/DB_1时，Dbeaver日志返回以下内容：

真的不知道如何使连接工作。SSH隧道显然可以工作，但是到db的连接失败了。我在另一个容器中运行了一个Spring Boot应用程序，并通过连接字符串jdbc:PostgreSQL：//db_1:5432/test将其连接起来。

对此有什么意见吗？是否0.0.0.0没有映射到内部网络？

Answer 1

你到底是如何运行你的集装箱的，我怀疑你可能错过了暴露港口？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，不想遇到某种端口干扰问题），然后通过访问docker和运行一些psql命令创建了一个数据库，如本答案所述，然后从DBeaver访问数据库

一切都很好！希望这能有所帮助。
