我使用了本教程：https://severalnines.com/blog/using-kubernetes-deploy-postgresql

我在Kubernetes上的配置基于官方Docker镜像，我不断得到：

psql -h <publicworkernodeip> -U postgres -p <mynodeport> postgres
Password for user postgres: example
psql: FATAL:  password authentication failed for user "postgres"
DETAIL:  Role "postgres" does not exist.
Connection matched pg_hba.conf line 95: "host all all all md5"

尝试使用以下命令登录

psql -h $（主机名-i）-U postgres

router.get('/', (req, res) => {
    ProReg.find()
    .sort({ date: -1 })
   this is not working // .populate({path:"products", populate:["oem", "category", "subcategory"]})
this is also not working // .populate("products", "oem")
    .then(proreg => res.json(proreg))
    .catch(err => res.status(404).json({ msg: 'No Pro Reg found' }));
});
