What is the correct way to use the dotnet images?

[prabhu]

I have a bunch of docker files which gets rebuilt on daily basis.

They are not complex. Below is a sample snippet.

FROM registry.suse.com/bci/dotnet-sdk:8.0

RUN zypper refresh && zypper --non-interactive update && zypper --non-interactive install -l --no-recommends git-core nodejs20 npm20 python311 python311-pip wget zip unzip make gawk java-21-openjdk-devel \
    && dotnet --list-sdks \
    && dotnet workload install android wasm-tools wasm-tools-net6 wasm-tools-net7 \
    && dotnet workload list

My problem is that on a given month, I am seeing at least three to four failures with these dotnet workflows. When things fail, there is hardly anything useful to troubleshoot. Below is the error I am getting today.

Usually, simply re-running the workflow a day or two later would resolve the issue. At times, I have tried removing the zypper refresh and zypper update commands, which might work for a day or two, before failing with another set of cryptic errors.

Am I missing something?

That is because there is a mismatch of versions. we can unforunately not ship 8.0.15 because it is incompatible with SLES ( see dotnet/runtime#113346 (comment) )

the straight forward part would to not install or update dotnet related packages. so specifically remove the zypper update from your dockerfile.
