Я постоянно получаю ошибку
=> ERROR [8/8] RUN CGO_ENABLED=0 GOOS=linux go build -a -installsuffix cgo -o main . 0.6s
------
> [8/8] RUN CGO_ENABLED=0 GOOS=linux go build -a -installsuffix cgo -o main .:
#16 0.603 no Go files in /app
------
executor failed running [/bin/sh -c CGO_ENABLED=0 GOOS=linux go build -a -installsuffix cgo -o main .]: exit code: 1
Команду RUN я пытался писать по разному, был вариант
RUN go build -o /go-web/cmd/goweb, но докер продолжает искать go файл в папке /app, что является WORKDIR в докер файле
Мой main файл находится в go-web(корневая папка)/cmd/goweb. Как сделать правильно?
