英文:
Using PGAdmin Extension in Docker Desktop for PostgreSQL Image: can't connect
问题
这是一个关于Docker和PGAdmin连接到PostgreSQL容器的问题。用户已经创建了一个PostgreSQL容器，并且容器内部的PostgreSQL数据库已经启动并且能够在终端中成功连接。然而，用户无法使用PGAdmin连接到这个PostgreSQL实例。
用户尝试了多种连接方式，包括使用本地IP地址、172.17.0.3 IP地址以及容器名称（pgserver）作为主机，但都遇到了连接被拒绝或连接超时的错误。
用户还提到他们已经安装了PGAdmin4 Docker Desktop扩展，并且确保SSL模式设置为"prefer"。
最后，用户提供了docker ps命令的输出，显示容器已经在端口54320上映射到PostgreSQL的5432端口。
用户想知道他们是否做错了什么，导致无法通过PGAdmin连接到PostgreSQL容器。
请注意，这是一个技术支持问题，需要进一步的调查和分析才能找到解决方法。

Question seems identical to https://stackoverflow.com/questions/31798160/can-not-connect-to-postgres-container-from-pgadmin but none of those solutions seem to be working, and I'm using slightly different tools... so maybe different problem?
In my Docker Desktop (running Windows with a Linux Docker), standard install, I've installed the postgres:latest image and created a container from it. I used the following settings:
The log in the container shows success:

On the terminal tab, I'm able to connect to the local instance:
# psql -p 5432 -U postgres
psql (15.3 (Debian 15.3-1.pgdg110+1))
Type "help" for help.

I did a docker inspect pgserver and saw the network settings as such:

I have also installed the PGAdmin4 Docker Desktop extension, but I cannot configure it to connect to my postgres instance.
- I have tried to connect to 127.0.0.1 on ports 5432 and 54320.
- I have tried to connect to 172.17.0.3 on the same ports.
- I have tried to connect to pgserver on the same ports.
- I have tried to connect to localhost on the same ports.
- I have ensured that SSL Mode is set to "prefer".
Depending on what I use, I get an error message that the connection is refused, or a connection timeout error.
What am I doing wrong?
Per request in comments, results of docker ps are below.
docker ps

我有一种感觉，问题不在于Docker或端口配置
而是特别是PostgreSQL的配置，其中定义了允许的连接位于
/var/lib/pgsql/12/data/pg_hba.conf
你可能需要像这样配置它
host all all 0.0.0.0/0 md5
你需要以一种通过卷保持持久性的方式来执行此操作。
英文:
I have a feeling that the problem is not docker or the port configuration
But the configuration of postgress in particular what connection are allowed defined in the
/var/lib/pgsql/12/data/pg_hba.conf
you may need to configure it like
host all all 0.0.0.0/0 md5
you need to do this in way the is persistent via volumes
