Golang revel framework hot-reload in docker environment

Question

I'm trying to set up golang environment as described in this great post. I'm using Docker on OS X 10.10 with boot2docker (v1.3.0) and fig.sh (1.0.1). Everything runs fine, but revel's hot-reload not working at all. Anyone experienced same problem or know any workaround to make hot-reload work? Revel framework version 0.11.1

What error are you seeing? There's no reason Revel shouldn't run as designed in Docker since Docker provides a shell and filesystem. I'd like to learn more about the problem you're having. — Brenden, Jan 05 '15 at 23:38

Boot2docker uses VirtualBox, and I'm assuming vboxsf for shared folders. vboxsf doesn't notify about changed files. Try keeping the files completely inside the virtual machine. Does that help?

How about something like this for a Dockerfile

FROM golang:1.17.2-alpine AS build

# Add required packages
RUN apk add --update git curl bash

# Install revel framework
RUN go get -u github.com/revel/revel
RUN go get -u github.com/revel/cmd/revel

WORKDIR /app

COPY go.mod go.sum ./
RUN go mod download

ENV CGO_ENABLED 0

ADD . .

ENTRYPOINT revel run

Then run using something like docker compose:

version: '3.9'

services:
  go-revel-crud:
    build:
      context: .
      dockerfile: ./Dockerfile.local
    ports:
      - 8090:8090
    volumes:
      - .:/app
    environment:
      - ENV=dev
      - PORT=8090

Mounting the volume for current directory to the working dir /app.
