无法连接pgbouncer和运行docker的postgres
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
这里是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
userlist.txt
“用户密码”
所以图像build立得很好。
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。
而pgbouncer给了我这个输出（由于某种原因，并不是说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中的这一行是不相关的。
host = mydb --link mydb:mydb
你应该阅读 – 链接容器内的使用。 您需要更新pgbouncerconfiguration与ENV提供的实际主机/端口 – 链接
