I'm new to writing Dockerfiles and using Swagger so I was wondering if someone could help me with one thing. I'm building a binary from Swagger generated server code and I need to pass in arguments specific to the go server when running it, but passing it into ENTRYPOINT or CMD gives me "unknown flag" error.

My Dockerfile looks like this:

FROM golang:1.10.1-alpine3.7 AS build

RUN apk add --no-cache git
RUN go get

WORKDIR /go/src/<path_to_workdir>
RUN dep ensure -vendor-only

WORKDIR /cmd/data-server
ENV SRC_DIR=/go/src/<path_to_src_dir>
RUN cd $SRC_DIR; go build -o data; cp data /cmd/data-server
ENTRYPOINT ["./data", "--scheme http"]

Which fails, on the previously mentioned error. How can I do this correctly?

    You can write

    ENTRYPOINT ["./data", "--scheme",  "http"]

    then you would simply need docker run name-of-image

    or you can pass the arguments when running the image

    docker run --scheme http
