I have a rails app and I use docker volumes to have the code persistent. Whenever I change anything in local the code gets reflected in the docker container, but those changes are getting reflecting in the browser. I'm not sure if I'm missing anything.
Right now every time there's a change in the code, I'm restarting the containers which is not the right way to do. Below is my docker-compose file
version: '3'
services:
webapp:
build: .
ports:
- '3001:3001'
volumes:
- '.:/data/checklist'
depends_on:
- db
- redis
environment:
DB_USERNAME: "root"
DB_PASSWORD: "Mission2019"
DB_DATABASE: "list"
DB_PORT: 3306
DB_HOST: db
RAILS_ENV: production
RAILS_MAX_THREADS: 5
db:
image: mysql:5.7
restart: always
environment:
MYSQL_DATABASE: "list"
MYSQL_ROOT_PASSWORD: "Mission2019"
MYSQL_USERNAME: "root"
redis:
image: redis:4.0-alpine
command: redis-server
ports:
- '6379:6379'
sidekiq:
depends_on:
- "db"
- "redis"
build: .
command: bundle exec sidekiq -C config/sidekiq.yml
This is my dockerfile
