CONTAINER1012 Error

[carlcamilleri]

Hi,

I am attempting to publish a project to a docker image from WSL2 but keep encountering CONTAINER1012, I would appreciate some pointers on this, please.

Setup details:

1. OS: Windows 11 with WSL2 Ubuntu 24.04.1
2. Container Management: Rancher Desktop 1.16.0

Publish Command:

dotnet publish "./myproj.csproj" -t:PublishContainer --verbosity "quiet" --nologo -p:ContainerRepository="myproj" -p:ContainerImageTag="latest"

Error encountered:

/home/myname/.dotnet/sdk/8.0.403/Containers/build/Microsoft.NET.Build.Containers.targets(242,5): error CONTAINER1012: The local registry is not available, but pushing to a local registry was requested

Below are the output of several commands executed within WSL2:

dotnet --list-sdks
8.0.303 [/home/ccamilleri/.dotnet/sdk]
8.0.403 [/home/ccamilleri/.dotnet/sdk]

I tried to reproduce this on my own WSL today and could not. I have a few questions about your environment.

• It looks like your Docker install is through Rancher Desktop as opposed to Docker Desktop - is that the case?
• Can you run ln -la $(which docker) to see where the Docker binary symlink is pointing to?

Broadly, we run the following commands internally for the SDK Tooling

• docker version
• docker info --format="{{ json .}}"
• docker load

We run these on a binary located from PATH, so if those are runnable from the CLI they should be usable from the tooling.
