所以这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
userlist.txt
“用户密码”
因此，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
我正在使用此命令启动它，并且我知道pgbouncer在工作，因为pgadmin尝试连接到数据库。
pgbouncer给了我这个输出(由于某种原因，它并没有说明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.
最佳答案
config和docker opts中的这一行不相关。
host = mydb
--link mydb:mydb
您应该阅读有关容器内部--link用法的信息。
您需要使用--link提供的来自ENV的真实主机/端口来更新pgbouncer配置
