Self-hosting Feedbin with Docker and OpenShift

author — Fri, 25 May 2018 17:32:49 GMT

Feedbin is an excellent RSS feed reader. You can sign up for its service and support its development. The company is gracious enough to offer its source code for DIYers to play with.

Prerequisites

API keys for Stripe and Skylight are required for running Feedbin. In addition, you need to pick a password for the PostgreSQL database. Populate the information in these two files:

db.env:

POSTGRES_PASSWORD=ChangeMe!
POSTGRES_DB=feedbin
POSTGRES_USER=feedbin

secrets.env:

PUSH_URL=http://feedbin.yourdomain.tls
SECRET_KEY_BASE=48_bit_secret
SKYLIGHT_AUTHENTICATION=
STRIPE_API_KEY=
STRIPE_PUBLIC_KEY=

Running Feedbin with Docker

You can find two Docker images here and here. The first image has to be used together with postgres, redis, memcached, elasticsearch, and nginx. The second image is all-in-one, minus postgres.

For the all-in-one image, you just need docker-compose.yml below in the same directory as the two files above. Then, run docker-compose up -d, and your Feedbin instance can be found at http://localhost:3000

docker-compose.yml:

version: '3'

services:
  db:
    image: postgres:10.4
    restart: always
    env_file:
      - db.env
    volumes:
      - db:/var/lib/postgresql/data

  app:
    image: rocwhite/feedbin-aio
    restart: always
    environment:
      - POSTGRES_HOST=db
    env_file:
      - db.env
      - secrets.env
    volumes:
      - app:/srv/apps/feedbin/current/public
    depends_on:
      - db

volumes:
  db:
  es:
  app:

With the other image, use this docker-compose.yml instead, along with a nginx.conf file.

docker-compose.yml:

version: '3'

services:
  db:
    image: postgres:10.4
    restart: always
    env_file:
      - db.env
    volumes:
      - db:/var/lib/postgresql/data

  rds:
    image: redis:3.2
    restart: always

  mcd:
    image: memcached:1.5
    restart: always

  es:
    image: elasticsearch:2.4
    restart: always
    volumes:
      - es:/usr/share/elasticsearch/data

  app:
    image: rocwhite/feedbin
    restart: always
    environment:
      - POSTGRES_HOST=db
      - MEMCACHED_HOST=mcd
      - REDIS_HOST=rds
      - ELASTIC_SEARCH_HOST=es
    env_file:
      - db.env
      - secrets.env
    volumes:
      - app:/srv/apps/feedbin/current/public
    depends_on:
      - db
      - rds
      - mcd
      - es

  web:
    image: nginx
    restart: always
    volumes:
      - app:/srv/apps/feedbin/current/public:ro
      - ./nginx.conf:/etc/nginx/conf.d/default.conf:ro
    depends_on:
      - app

volumes:
  db:
  es:
  app:

Running Feedbin on OpenShift

You probably need a Pro instance with > 1GB memory to run Feedbin. Once you create a new project, import db.env and secrets.env (see above) as secrets:

oc create secret generic feedbin-db --from-env-file=./db.env --type=opaque
oc create secret generic feedbin-secrets --from-env-file=./secrets.env --type=opaque

Then create a new app using the template file below.

oc new-app -f ./openshift-aio.yml
