Support kubernetes about imagewolf HOT 6 CLOSED

Probably the best way to do this is to use a daemon set and an image wolf namespace. Then we can just do a GET request for the pods in the namespace.

Actually, the downward API may be the easiest way to get the pod info, if it has the needed data https://kubernetes.io/docs/tasks/inject-data-application/downward-api-volume-expose-pod-information/#the-downward-api

I suspect it only exposes info about the given pod though :(

Using DaemonSet and headless Service allow proper peer discovery: #6

Thanks Etienne! Just taking a look at this now.

If you hit some version issue between Docker client and the api, you need to downgrade the Docker client version. I had that issue while testing on GKE. Using the following multistage Dockerfile fixed it:

# Build stage
FROM golang:1.8 as builder

WORKDIR /go/src/

COPY src .

RUN go get github.com/anacrolix/torrent
RUN go get github.com/anacrolix/utp
RUN go get github.com/docker/distribution/notifications

RUN CGO_ENABLED=0 GOOS=linux go build -a -installsuffix cgo -o app .

# Run stage
FROM alpine:3.4
RUN apk --no-cache add ca-certificates docker=1.11.2-r1

WORKDIR /root/

COPY --from=builder /go/src/app .

EXPOSE 6000

CMD ["./app"]

Closed via #7
