Docker failing to start rails

I'm trying to start my rails application using rails. It depends on redis, which seems to be working but when rails server starts it fails with Cannot assign requested address - connect(2) for [::1]:6379 (Errno::EADDRNOTAVAIL).

Dockerfile

FROM ruby:2.6.1

RUN apt-get update -yqq && \
  apt-get install -yqq --no-install-recommends \
  nodejs \
  nano

COPY Gemfile* /usr/src/app/
WORKDIR /usr/src/app
RUN bundle install
RUN gem install foreman
RUN gem install rake -v 12.3.2

COPY . /usr/src/app/

CMD [ "bin/rails", "s", "-b", "0.0.0.0" ]

.docker-compose.yml

version: '3'

services:
  postgres:
    image: 'postgres:10.3-alpine'
    volumes:
      - 'postgres:/var/lib/postgresql/data'
    env_file:
      - '.env'

  redis:
    image: 'redis'
    # volumes:
    #   - 'redis:/data'

  rails:
    depends_on:
      - 'postgres'
      - 'redis'
    build: .
    ports:
      - '3000:3000'
    volumes:
      - '.:/usr/src/app'
    env_file:
      - '.env'

volumes:
  redis:

Cannot assign requested address - connect(2) for [::1]:6379 (Errno::EADDRNOTAVAIL)

Your rails application is trying to connect to redis via localhost but the service is on a different container. Try connecting to redis:6379 instead.
