如何将本地 postgreSQL 连接到 docker（CVAT）

Question

我正在尝试将本地 postgreSQL 服务器（数据库名称 = cvat_lcl）连接到使用 docker-compose 创建的容器：连续可变功率放大器。我可以使用本地 pgAdmin 读取容器内托管的普通数据库（在端口 5444 上），但我部署的最终目标是运行本地版本的 postgresql 并让 CVAT 容器连接到该数据库而不是内置数据库。我是网络方面的新手，所以不太确定从哪里开始。

我目前所做的：

pg_hba.conf：

# Database administrative login by Unix domain socket
local   all             postgres                                peer

# TYPE  DATABASE        USER            ADDRESS                 METHOD

# "local" is for Unix domain socket connections only
local   all             all                                     peer
# IPv4 local connections:
host    all             all             127.0.0.1/32            md5
# IPv6 local connections:
host    all             all             ::1/128                 md5
# Allow replication connections from localhost, by a user with the
# replication privilege.
local   replication     all                                     peer
host    replication     all             127.0.0.1/32            md5
host    replication     all             ::1/128                 md5
host    all             all             172.17.0.0/16           md5

postgres.conf

# - Connection Settings -

listen_addresses = '*'          # what IP address(es) to listen on;
                                        # comma-separated list of addresses;
                                        # defaults to 'localhost'; use '*' for all
                                        # (change requires restart)
port = 5433                             # (change requires restart)

总结一下——目标是连接到伐木场CVAT 容器中的数据库（在本地主机上）。CVAT 当前在 Linux 20.04 LTS 上运行。在此先感谢您的帮助。
