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 :

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

 > [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?

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"]

[jean]

maybe the doc should mention that devs have to replace this docker value by their actual project name

I am glad you solved it. I've created an issue to address this problem.
