Question

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

以下是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，我知道pgbouncer正在运行，因为pgadmin尝试连接到数据库。

并且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）。

以下是我在pgadmin中可以看到的内容

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

Answer 1

config和docker opts中的这一行没有核心化。

host = mydb
--link mydb:mydb

您应该阅读容器内的--link使用情况。您需要使用ENV提供的真实主机/端口更新pgbouncer配置，该链接由提供

无法连接与docker一起运行的pgbouncer和postgres
