【问题描述】：

我为 PGbouncer 创建了一个 docker 容器。（Docker 镜像来自 -https://hub.docker.com/r/edoburu/pgbouncer）

docker run -d -it --name=pb -e DB_NAME=events -e DB_HOST=localhost -e DB_USER=postgres -e DB_PASSWORD=postgres  -e LISTEN_ADDR=127.0.0.1 -e LISTEN_PORT=8083 -e AUTH_TYPE=any -e AUTH_FILE=/Users/nandeeshnaik/Desktop/pg/userlist.txt brainsam/pgbouncer:latest

上面的命令运行 pgbouncer。来自 docker 容器的日志，

adduser: user 'postgres' in use
#pgbouncer.ini
# Description
# Config file is in “ini” format. Section names are between “[” and “]”.
# Lines starting with “;” or “#” are taken as comments and ignored.
# The characters “;” and “#” are not recognized when they appear later in the line.
[databases]
* = host=localhost port=5432 user=postgres password=postgres

[pgbouncer]
# Generic settings
listen_addr = 127.0.0.1
listen_port = 8083
auth_file = /Users/nandeeshnaik/Desktop/pg/userlist.txt
auth_type = any
ignore_startup_parameters = extra_float_digits

# Log settings
admin_users = postgres

# Connection sanity checks, timeouts

# TLS settings

# Dangerous timeouts

在此之后，我尝试使用 postgres 客户端 (PSQL) 连接到 pgbouncer。

psql -h 127.0.0.1 -p 8083 -U postgres events

我收到以下错误..

(base) MUMCAP0120:pg nandeeshnaik$ psql -h 127.0.0.1 -p 8083 -U postgres events
psql: could not connect to server: Connection refused
    Is the server running on host "127.0.0.1" and accepting
    TCP/IP connections on port 8083?

使用 Mac
本地安装的 Postgresql。
userlist.txt 只有 "postgres"，用户名和密码都在痛苦文本中。

非常感谢任何解决此问题的建议和解决方案。

如果您需要更清楚的说明，请告诉我。

【解决方案1】：

你错过了docker run命令的端口映射标志，所以它应该是docker run -p 8083:8083 ...：

docker run -d -p 8083:8083 -it --name=pb -e DB_NAME=events -e DB_HOST=localhost -e DB_USER=postgres -e DB_PASSWORD=postgres  -e LISTEN_ADDR=127.0.0.1 -e LISTEN_PORT=8083 -e AUTH_TYPE=any -e AUTH_FILE=/Users/nandeeshnaik/Desktop/pg/userlist.txt brainsam/pgbouncer:latest

即使添加了“-p 8083:8083”也没有运气。同样的错误。
