I'm new to docker-compose and go so be kind. I've looked at similar questions to this on SO, but they're either 1) for different versions of Go or 2) for Linux. I'm on Windows 10. Go version is 1.19

I'm trying to follow along with a course which is out of date of course, and they're using a Mac, so that might be another reason why this isn't working, but I have a project structure and files that look like this (highlighted areas of interest):

currentEnv

When I try to run the command docker-compose up like it says in the course, I get the error. What's causing it and how do I fix it (as a newbie asking)?

docker-compose docker go

You could try something like this where you build first and then try to run the binary. here is the docker documentation on it

and in case the link breaks:


FROM golang:1.16-alpine

WORKDIR /app

COPY go.mod ./
COPY go.sum ./
RUN go mod download

COPY . ./

RUN go build -o /<your binary name>

EXPOSE 8080

CMD [ "/<same binary name>" ]
