Dev instructions

Do not forget to execute the main command in container with exec!!! Double check that puma, sidekiq or something else is running in container with PID 1!!!

start in development:

docker-compose up

if there is no images and command fails:

docker-compose build

and then docker-compose up

By default docker reads docker-compose.yml and docker-compose.override.yml

docker-compose.override.yml contains overrides for development. docker-compose.staging.yml - for staging. docker-compose.production.yml - for production.

To use rails console:

docker-compose exec backend rails c

To use pry:

docker-compose stop backend && docker-compose run --service-ports backend

Deploy instructions

install docker at remote machine:

docker-machine create --driver generic \
   --generic-ip-address REMOTE_HOST_IP \
   --generic-ssh-user REMOTE_HOST_USER \
   --generic-ssh-key KEY_PATH \
   --engine-storage-driver devicemapper \
   MACHINE_NAME

attach your docker client to remote machine:

eval $(docker-machine env MACHINE_NAME)

build all containers:

  • production:

    docker-compose \
  --project-name PROJECT \
  -f docker-compose.yml \
  -f docker-compose.production.yml \
  build --no-cache

  • staging:

    docker-compose \
  --project-name PROJECT \
  -f docker-compose.yml \
  -f docker-compose.staging.yml \
  build --no-cache

start all containers:

  • production:

    docker-compose \
  --project-name PROJECT \
  -f docker-compose.yml \
  -f docker-compose.production.yml \
  up -d

  • staging:

    docker-compose \
  --project-name PROJECT \
  -f docker-compose.yml \
  -f docker-compose.staging.yml \
  up -d

* To build only one container, for example frontend in production, run:

docker-compose \
  --project-name PROJECT \
  -f docker-compose.yml \
  -f docker-compose.production.yml \
  build --no-cache \
  frontend

** To start it attached to console, run:

docker-compose \
  --project-name PROJECT \
  -f docker-compose.yml \
  -f docker-compose.production.yml \
  up \
  frontend

*** To attach to the existing container, run:

docker-compose \
  --project-name PROJECT \
  -f docker-compose.yml \
  -f docker-compose.production.yml \
  exec \
  frontend /bin/bash

*** To view logs

docker-compose \
  --project-name PROJECT \
  -f docker-compose.yml \
  -f docker-compose.production.yml \
  logs -f
