所以这里是启动数据库的命令

sudo docker run --name mydb -e "POSTGRES_USER=user" -e "POSTGRES_PASSWORD=password" -t -d postgres

这是 pgbouncer 的 dockerfile

from ubuntu
RUN apt-get update && apt-get -y install pgbouncer
COPY /pgbouncer.ini /etc/pgbouncer/
COPY /userlist.txt /etc/pgbouncer/
EXPOSE 6543

这是 pgbouncer 的设置

[databases]
host = mydb

[pgbouncer]
pool_mode = session
listen_addr = localhost
listen_port = 6543
auth_type = plain
auth_file = userlist.txt
user = postgres

用户列表.txt

“用户密码”

所以图像构建良好。

sudo docker run  -P -p 6543:6543 --name pgbouncer --link mydb:mydb -t leos/pgbouncer pgbouncer /etc/pgbouncer/pgbouncer.ini

我用这个命令启动它,我知道 pgbouncer 正在工作,因为 pgadmin 试图连接到数据库。

pgbouncer 给了我这个输出(由于某种原因,它没有说明 pgbouncer 是否连接到数据库)。

这是我在 pgadmin 中可以看到的

 Error: Error connecting to the server: server closed the connection unexpectedly
    This probably means the server terminated abnormally
    before or while processing the request.

config 和 docker opts 中的这一行不相关。

host = mydb
--link mydb:mydb

您应该阅读容器内的 --link 用法。您需要使用 --link 提供的 ENV 中的真实主机/端口更新 pgbouncer 配置
