postgresql - 如何修复konga_db

Question

这是 docker

0e60f32df539        pantsel/konga:legacy                                               "/app/start.sh"          3 days ago          Up 1 second         0.0.0.0:1337->1337/tcp                                               konga

我尝试安装

docker run --rm --network=kong-net pantsel/konga -c prepare -a postgres -u postgresql://kong@kong-database:5432/konga_db

这是错误的

debug: Preparing database...
Using postgres DB Adapter.
Failed to connect to DB { Error: getaddrinfo ENOTFOUND kong-database kong-database:5432
    at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:67:26)
  errno: 'ENOTFOUND',
  code: 'ENOTFOUND',
  syscall: 'getaddrinfo',
  hostname: 'kong-database',
  host: 'kong-database',
  port: 5432 }

如何解决错误？

Answer 1

由于该错误意味着无法找到您为PostgreSQL引用的域名。如果您在同一VM上运行所有Docker容器，请尝试将kong-database更改为确切的主机名，即“localhost”。

该命令应如下所示:

docker run --rm --network=kong-net pantsel/konga -c prepare -a postgres -u postgresql://kong@localhost:5432/konga_db

正如@atline所建议，还请确认您的 docker 网络，并使用 docker network ls确认它应如下所示:

NETWORK ID          NAME                DRIVER              SCOPE
