Moved from GitHub dgraph/3221

Posted by pjebs:

Is it possible for official docker image to use alpine distribution of linux.

All the other main databases provided at a minimum an alpine version.

Alpine simply has a smaller size footprint.

For now, you could use the following Dockerfile for creating an alpine based image. We will see if it is possible to add this to official docker images.

######################
# STEP 1 build dgraph
######################
FROM golang:1.12-alpine3.9 AS builder

# build custom branch
ARG DGRAPH_BRANCH=master

# Install git
RUN apk update && apk add --no-cache git

# build dgraph binary
RUN go get -d -v github.com/dgraph-io/dgraph/dgraph
RUN cd $GOPATH/src/github.com/dgraph-io/dgraph && git checkout ${DGRAPH_BRANCH}
RUN CGO_ENABLED=0 go build -v -o /dgraph github.com/dgraph-io/dgraph/dgraph

#####################
# STEP 2 build image
#####################
FROM alpine

COPY --from=builder /dgraph /usr/local/bin/dgraph

RUN mkdir /dgraph
WORKDIR /dgraph

EXPOSE 8080
EXPOSE 9080

CMD ["dgraph"]

Possible reasons to use Alpine image -

  • Alpine based image reduce the attack surface area
  • Smaller in size compared to Ubuntu based image

Todo: Need to install ca-certificates in the image so that telemetry can work.
