Question

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

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

以上命令运行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仅具有“ postgres” ，用户名和密码均位于痛苦的文本中。

任何解决该问题的建议和解决方案都将受到赞赏。

如果您需要进一步的说明，请告诉我。

您错过了docker run命令的端口映射标志，因此应该为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

无法使用psql连接到Pgbouncer
