连接postgreSQL+；来自我的本地网络的postGIS docker容器

我已使用以下内容构建了docker容器：

它就像我桌面上的一个魔咒，我可以使用psql与服务器交互。它工作得很好

psql -h 172.17.0.2 -p 5432 -U postgres

但我想让我的同事连接数据库，我不太了解它是如何工作的

此时（如果我们假设我的本地IP是

192.168.0.14

）

不起作用

我发现了一些链接，如：

---

但它仍然清晰可见

您需要做的是在运行容器时进行端口映射

docker run -p 5432:5432 --name some-postgis -e POSTGRES_PASSWORD=mysecretpassword -d mdillon/postgis

---

这将把主机上的5432（左侧）映射到容器上的5432（右侧）。只要您的IP可以从他的计算机访问，您的同事就可以访问DB

您的同事无法连接的原因是您正在使用主机对接内部IP地址，而您的同事计算机没有意识到172.17.0.2地址托管在您的计算机上

因此，正确的机制如@Tarun Lalwani所述

---

现在，您的同事将使用您的机器进行连接，即dockers公共ip地址的主机

我已经编辑了我的问题<代码>-p 5432:5432不等同于

-p“$POSTGRES\u PORT\u 5432\u TCP\u PORT”

？如果我执行

docker run-d-p5432:5432 postgres

操作，它不会创建另一个docker？该命令只是一个示例。根据您发布的命令更新了答案<代码>--link现在不推荐使用。您可能应该使用

docker compose

如何使用

docker compose

？

psql -h 192.168.0.14 -p 5432 -U postgres

docker run -p 5432:5432 --name some-postgis -e POSTGRES_PASSWORD=mysecretpassword -d mdillon/postgis
