Invalid endpoint

[DeepSnowNeeL]

Hello i'm trying to use minio on docker containers, and I usually use docker names as hostnames since it resolves correctly with the docker DNS system.

But I can't because I got this exception :
Minio.Exceptions.InvalidEndpointException: 'Minio API responded with message=Endpoint: minio_recette does not follow ip address or domain name standards.'

I use both the java & c# api for minio, and solved my problem on the java side by using http://minio_recette:9000 as my endpoint, but the c# doesn't allow for "/" in the endpoint.

Could you please support simple names, for docker containers ? Thanks

I'm still trying to find a way around this...

@DeepSnowNeeL, init the c# client like this and it should work.

private static MinioClient minio = new MinioClient("minio_recette:9000",
                "accesskey",
                "secretkey"
                );

It doesn't, i even tried using the network name like "minio_recette.my_network:9000" with or without the port I get the same exception

PS : You can try the endpoints without having the server running, the exception pops up.

Edit:

Things I tried :
"minio_recette"
"minio_recette:9000"
"minio_recette.my_network"
"minio_recette.my_network:9000"
"http://minio_recette"
"http://minio_recette:9000"

Right now i'm going for "192.168.0.6" which is my container ip on the docker network, I hope at least this works.

This is strange because I use "http://localhost:9010" locally and it worked, the difference is that i'm on windows, and I have a minio container with port forwarding and on the server its a debian and it's 2 containers (one for c# the other for minio) they are on the same docker network but minio crashes

@DeepSnowNeeL, my mistake - we need a proper ip address or endpoint url.Will check on this feature request and let you know.

[DeepSnowNeeL]

Great :)
Please make it work for the java API as well. (and others ?)

Btw, It works when I specify the IP directly so I'll use that for now

This is causing us issues aswell.
With docker this is definitely needed as docker distincts stacks based on stackname_servicename.

Also underscore can be a valid part of a DNS name. See (https://en.wikipedia.org/wiki/Hostname#Restrictions_on_valid_host_names):

While a hostname may not contain other characters, such as the underscore character (_), other DNS names may contain the underscore

As you don't know what the primary DNS suffix is, a host with underscore should be allowed.

Something like that is valid as a domain according to wikipedia:
storage_proxy(.domain.com)

Related Regex that is not checking for underscores:

minio-dotnet/Minio/Helper/RequestUtil.cs

Line 139 in 4cc085f

Regex validLabel = new Regex("^[a-zA-Z0-9]([A-Za-z0-9-]*[a-zA-Z0-9])?$");

We are welcoming PRs for this since we currently don't have the cycles to take this on atm. Would @WolfspiritM or @DeepSnowNeeL if you want to send PR, we'd be really glad.

For the dotnet project, I am using I used only the IP: Port configuration i.e. "127.0.0.1:9000".

[deekoder]

Will address in the future. As mentioned earlier, we will reactivate this into current milestone when we are done with current priorities.

I see the issue was reported closed? Have there been any updates or workaround figured for this issue?
