I recently ran into an issue with building my Go app in one container and then running it in another one. I do this to make my container image smaller.
CGO_ENABLED=0, in a multi-stage build, it will say something like the
exec /app/main: no such file or directory.
FROM golang:1.16 AS builder WORKDIR /src/ COPY main.go go.mod go.sum /src/ RUN go get # Without `CGO_ENABLED=0`, in a multi-stage build, it will say something like # exec /app/main: no such file or directory RUN CGO_ENABLED=0 go build -o /src/main /src/main.go FROM alpine:latest WORKDIR /app/ COPY --from=builder /src/main /app/main COPY index.html /app/ EXPOSE 8080 ENTRYPOINT [ "/app/main" ]
