The issue is within that statement: COPY ./src/MarketData.Messages/MarketData.Messages.csproj ./MarketData.Messages/.

failed to compute cache key: "/src/MarketData.Messages/MarketData.Messages.csproj" not found: not found

How are you running the build? It ahould be from the root and docker build . -f src/Dockerfile The ‘.’ Denotes the build context, or in other words, the parent directory that is made available to the docker build process

I wish I wrote that post earlier. It took me 2 hours thanks a lot! 🙂 @Cisien, I need to create Dockerfiles for MarketData.Subscriber and MarketData.Api which now works thanks to you. However, what about the .dockerignore file? Do I keep it into the root directory or next to the Dockerfiles in both projects?

Cisien•2y ago

Either, like .gitignore it applies scoped to the directory its in. Usually one at the root is sufficient

Hulkstance•2y ago

Thank you very much! 🙂 @Cisien damn, there is an issue with the .proto files

Looks like your not copying everything in

Hulkstance•2y ago

Hulkstance•2y ago

that should be it @Cisien, normally I would have to build first the Messages project, so it can generate the .cs files out of the .proto files maybe that's causing it but I'm not sure how to do it with Dockerfile

Cisien•2y ago

Might be Be explicit with your steps Try creating a project reference to the messages project from the one that fails That should get the ordering sorted

Hulkstance•2y ago

MarketData.Subscriber already references the MarketData.Messages

Hulkstance•2y ago

Hulkstance•2y ago

and this is the Messages.csproj it builds just fine locally @Cisien is there a way to inspect what's in /app/src on the docker? like which folders, which files

Cisien•2y ago

You can run shell commands
