FROM node:carbon AS web-build-env
ENV BUILD_HOME=/go/src/github.com/ubclaunchpad/inertia/daemon/web
# Mount source code.
ADD ./daemon/web ${BUILD_HOME}
WORKDIR ${BUILD_HOME}
# Build and minify client.
RUN npm install --production
RUN npm run build

### Part 2 - Building the Inertia daemon
FROM golang:alpine AS daemon-build-env
ARG INERTIA_VERSION
ENV BUILD_HOME=/go/src/github.com/ubclaunchpad/inertia \
    INERTIA_VERSION=${INERTIA_VERSION}
# Mount source code.
ADD . ${BUILD_HOME}
WORKDIR ${BUILD_HOME}
# Install dependencies if not already available.
RUN if [ ! -d "vendor" ]; then \
    apk add --update --no-cache git; \
    go get -u github.com/golang/dep/cmd/dep; \
    dep ensure -v; \
    fi
# Build daemon binary.
RUN go build -o /bin/inertiad \
    -ldflags "-w -s -X main.Version=$INERTIA_VERSION" \
    ./daemon/inertiad
