daveblack93 · 2023-01-05T14:46:48Z

Hi @skt005,
we have maybe the same issue with a private feed hosted in onprem gitlab istance, my question is what have you inserted in the DNS array? I mean which hostname/ip?

Thanks.

Thanks for posting the fix! That's crazy that the workaround is adding DNS entries to Docker!!!

balajivijayakumar1994 · 2023-03-07T07:07:29Z

hi @mpowrie ,

Can you please tell me Which DNS address we have to put here in order to work.

Thanks

mpowrie · 2023-03-07T07:50:32Z

Sure - "dns":["1.1.1.1","8.8.8.8"],

For anyone not using docker desktop, this also works in the free alternative Container Desktop

balajivijayakumar1994 · 2023-03-15T07:36:21Z

Its not working out even after adding it

jamespagedev · 2023-04-18T00:43:30Z

I'm seeing the same issue...

I've updated my config file in desktop docker -> docker engine settings...

However the issue still persists...

The strange thing is, it works fine in another project...

Anyone have any ideas?

douglasg14b · 2023-04-18T01:06:19Z

This just started happening to me as well, worked yesterday, hosed today. Running the docker build on WSL.

I can restore fine outside of docker.

Updating DNS did not work, anyone have ideas?

jamespagedev · 2023-04-18T01:21:46Z

I'm seeing the same issue...

I've updated my config file in desktop docker -> docker engine settings...

However the issue still persists...

The strange thing is, it works fine in another project...

Anyone have any ideas?

So I got it to work. I'm not sure which of these steps made it work, but here they are...

I updated version 4.17 to 4.18. The update hung during the install and I had to kill all docker running processes and services. While killing the docker processes, I noticed there were .net tasks running (usually happens after running dotnet commands and they hang), so I also killed those processes to ensure nothing would be stuck in the handlers.

After starting docker back up, and clicking yes to start everything, it immediately closed docker desktop and began installing the updates. After it finished, I started docker desktop again, and waited a while for it to start up, and it did.

I executed the command again and success!

Hope this helps anyone else here. Thanks and take care.

Facing the below error when dotnet restore is being executed from within docker
error NU1301: Unable to load the service index for source https://api.nuget.org/v3/index.json

Tried setting up dns property in Docker engine as suggested above. But no luck.
Packages are getting restored from Visual studio as well dotnet restore command also is working fine when executed outside docker.
Issue seen only when ran with docker.

Any solutions?

Setting up "MaxProtocol" to TLS 1.2. For example on ubuntu image

echo "MaxProtocol = TLSv1.2" >> /etc/ssl/openssl.cnf && dotnet restore

sairamaj · 2023-05-31T21:33:55Z

For me the below steps before dotnet restore worked as ZScaler is installed on my machine. Exported ZScaler from Certificate store.

COPY zscalar.cer .
ADD zscalar.cer /usr/local/share/ca-certificates/zscalar.cer
ADD zscalar.cer /etc/ssl/certs/zscalar.cer
RUN chmod 644 /usr/local/share/ca-certificates/zscalar.cer && update-ca-certificates

balajivijayakumar1994 · 2023-06-22T07:49:48Z

I think it could be firewall issue with laptop on accessing the URls from docker image

a-chumbler · 2023-07-12T13:01:34Z

Hey, I had the same issue, and I figured out that this problem disappears when I install curl or wget.
So I added the following line to my Dockerfile before running dotnet publish:

RUN apt-get install -y wget

It seems like the distribution is missing some packages required for performing HTTPS calls.

dev4884 · 2023-08-06T19:55:33Z

YES!!! This works for me! I am so glad I found this. I have been banging my head against this wall for way too long!

reddyrajhanu2024 · 2024-01-23T06:10:14Z

"dns":["1.1.1.1","8.8.8.8"],

this DNS doesn't help me.

jfaigan · 2024-01-23T15:13:29Z

"dns":["1.1.1.1","8.8.8.8"],

this DNS doesn't help me.

FYI, it did not help me either. My problem was that I was being blocked from accessing the Internet from inside the container. I needed to provide the root certificate in order to succeed. You can see my previous post for details.

Hope this helps.

In our case we run Kubernetes using Docker Desktop and deployed dotnet application, which stuck with a similar error

error NU1301: Unable to load the service index for source https://api.nuget.org/v3/index.json.

DNS name api.nuget.org can't be resolved inside the Pod and probably because of the networking related issue. However, most of the other names resolved successfully.

Did a try to set different MTU, but still see same 1500 inside the Pod

vi "$HOME/Library/Group Containers/group.com.docker/settings.json"

  "vpnKitMTU": 1472,

checks

Deploy a simple Pod with Ubuntu

  namespace: default
spec:

Adding DNS entry worked for me. It is an issue docker intermediate container is not able to reach api.nuget.org. It could be due to firewall , vpn or any other issue specific to respective machine.

I had the same issue with gitlab runners (local gitlab instance + local runner + PODMAN) . When trying to build the project using anything but gitlab runner - everything worked perfectly. However when we tried to use CI, the process failed with error NU1301: Unable to load the service index for source https://api.nuget.org/v3/index.json .

If you use podman with gitlab runners dns works.
Just put it in your gitlab runner config file.

In my case it worked when I connected to a VPN i was using when i started off the build.
