How can I set http not https container registery?

[dameng324]

My company has a local habor as internal container registery which use http only as only internal use.

but I set <ConainterRegistery> Property in my project and cannot push it.

Encountered a SocketException with message "An existing connection was forcibly closed by the remote host.". Pausing before retry.

I guess the reason is default is https, can I set http protocol?

addition info:

I have already set docker insecure-registries config

  "insecure-registries": [
    "dockerhub.shengguanda.com"
  ]

If I use a Dockerfile and build with docker command, it will be fine.

We don't support insecure registries yet, but adhering to docker configuration is probably a great way for us to go when we do support this. Is this something you'd be interested in helping contribute?

I found the point here.

https://github.com/dotnet/sdk/blob/3a44947ed697a848c2ee667411e4b4127d3393fc/src/Containers/Microsoft.NET.Build.Containers/ContainerHelpers.cs#L150-L154

Check the local docker config, If the registery is localhost or contained in insecure-registeries , will add http prefix, otherwise https.

I'm glad to help contribute this. but need some help, Is there any recommend api to get the local docker config?

We don't yet have any code for reading the docker config file, because the only current use of that file is for authentication. Our use is in another library, https://github.com/mthalman/docker-creds-provider/blob/main/src%2FValleysoft.DockerCredsProvider%2FCredsProvider.cs, that hides this implementation detail.

I think it would be ok to put an initial implementation into the SDK repo, then later we can decide if the Valleysoft library is the correct final destination for the code.

It's really helpful. Thanks, I will try this.

@baronfel Hi, I use DockerCli.GetDockerConfig() to get the local docker config and create a PR to do this in this PR(dotnet/sdk#39840).

I create a nukpg for fix this problem. I can't push it to nuget.com because I dont want changed the package name. I just changed the version postfix.

If you run into this issue, you can download this package and put the nupkg file to your local nuget package source.
Then change the Microsoft.NET.Build.Containers version to 8.0.203-sgd

  <ItemGroup>
<!-- <PackageReference Include="Microsoft.NET.Build.Containers" Version="8.0.203" />-->
      <PackageReference Include="Microsoft.NET.Build.Containers" Version="8.0.203-sgd" />
  </ItemGroup>

It will work on 8.0.203 sdk version.
