I m trying to publish my ktor app through docker by following this doc <https ktor io docs docker html building and running the docker image> When running `docker build t my app ` I m getting this error message ```= gt ERROR 3 4 COPY build install docker app gt 3 4 COPY build install docker app failed to compute cache key build install docker not found not found``` What am I doing wrong here

=> ERROR [3/4] COPY ./build/install/docker/ /app/                                                                                                                                             
------

What am I doing wrong here?

It's assumed that name of your project is

docker

. Maybe that's the problem. You can try to replace the path to

./build/install/<project-name>

yeah I tried that too, and I was running into another issue down the line. Let me try again to see what it was

docker: Error response from daemon: OCI runtime create failed: container_linux.go:367: starting container process caused: exec: "./docker": stat ./docker: no such file or directory: unknown.

I figured it out! I also had to replace

CMD ["./my-app"]

maybe the doc should mention that devs have to replace this

docker

value by their actual project name
