While I very much appreciate to have my identity stored in Ledger hardware, it is way too restrictive to require that desktop users run a node. I failed to find a Docker image, but then again I was not motivated when met with this requirement.
I suggest that you provide the address of a node which Concordium itself manages. This could be the default in node settings.
Alternatively, if you could point me to a Docker image, I will try and run it in Docker Desktop with WSL 2 on my Windows PC. It’s an Intel NUC, I doubt it will be sufficiently powerful.
Alternatively, if you could point me to instructions on how to install a node on Azure, I could try that.
