a2d

Application to Docker (A2D) is a tool that is able to dockerize a single application.

usage

docker run -v $PWD:/projectName utrecht/a2d:1.0.0 \
       -projectName someProjectName -dockerfile /projectName/Dockerfile

creates a Dockerfile. If one does not have docker installed, one could issue:

./a2d -h

and the following output would be returned:

FROM golang:1.12.4-alpine as builder
COPY . ./someProjectName/
WORKDIR someProjectName
RUN adduser -D -g '' someProjectName && \
    apk add git && \
    CGO_ENABLED=0 go build && \
    cp someProjectName /someProjectName && \
    chmod 100 /someProjectName

FROM scratch
COPY --from=builder /etc/group /etc/group
COPY --from=builder /etc/passwd /etc/passwd
COPY --from=builder --chown=someProjectName:someProjectName /someProjectName /usr/local/someProjectName
COPY --from=builder /etc/ssl/certs/ca-certificates.crt /etc/ssl/certs/
USER someProjectName
ENTRYPOINT ["/usr/local/someProjectName"]
