[5 Minutes Docker Series] Deploy A Free RSS Aggregator Website - Miniflux

I have been looking for a free online web service which can aggregate the updates from hundreds of websites I collected in my bookmark. I even built my own bookmark site for easily managing the collections. Click through hundreds of website to see the updates is a really pain to me and since lots of websites are not updating that often, but once they updated , I really want to check out their contents since that is usually interesting to me. 

I found RSS aggregator service could help for my this problem. But all of this kind of online service are not free or not free enough for me to get what I need. I decided to look for a self-hosted RSS aggregator solution. That is how I started this post. 




Introduction

I have searched online and found following two posts helps me to narrow down the scope for the applications. 
If you want to check out all other solutions, you can check above sites to get more. For me, I have not check out too much, but following three are most interesting ones I tried a bit:
  • Tiny Tiny RSS
  • FreshRSS
  • miniflux
  • Stringer

miniflux

Actually it is hard decide which one is best for all above four I mentioned. I do not have much time to go through all of them deep so from the simlicity of installation point of view, I choosed miniflux to use as my daily RSS reader.
It also has other benefits:
- easy to read cross multiple devices.
- free, open source, light weight for resource usage

Installation from Docker

Docker Registries:


Docker Architectures:

  • amd64
  • arm64
  • arm/v7
  • arm/v6

Using 

1 Log in to Play With Dcker website and create a new instance

URL: https://labs.play-with-docker.com/


2 In the new instance session command line, create a new file: basic.yml

You can find out this basic.yml file and other version's yml file from this url:

  • vi basic.yml

3 In this new basic.yml file, paste into follow text:

version: '3.4'
services:
  miniflux:
    image: miniflux/miniflux:latest
    ports:
      - "80:8080"
    depends_on:
      - db
    environment:

      - POSTGRES_PASSWORD=secret
    volumes:
      - miniflux-db:/var/lib/postgresql/data
    healthcheck:
      test: ["CMD", "pg_isready", "-U", "miniflux"]
      interval: 10s
      start_period: 30s
volumes:

5 Open Port 80 to visit this website


6 Log in with default credential admin / test123





Installation from Portainer

 

1 Log into your portainer website



2 Create a new custom template with following texts

You can find out this basic.yml template file and other version's yml file from this url:

https://github.com/miniflux/v2/tree/master/contrib/docker-compose


version: '3.4'
services:
  miniflux:
    image: ${MINIFLUX_IMAGE:-miniflux/miniflux:latest}
    container_name: miniflux
    restart: always
    ports:
      - "8010:8080"
    depends_on:
      - db
    environment:
      - DATABASE_URL=postgres://miniflux:[email protected]/miniflux?sslmode=disable
      - RUN_MIGRATIONS=1
      - CREATE_ADMIN=1
      - ADMIN_USERNAME=admin
      - ADMIN_PASSWORD=test123
      - DEBUG=1
    # Optional health check:
    # healthcheck:
    #  test: ["CMD", "/usr/bin/miniflux", "-healthcheck", "auto"]
  db:
    image: postgres:15
    container_name: postgres
    environment:
      - POSTGRES_USER=miniflux
      - POSTGRES_PASSWORD=secret
    volumes:
      - miniflux-db:/var/lib/postgresql/data
    healthcheck:
      test: ["CMD", "pg_isready", "-U", "miniflux"]
      interval: 10s
      start_period: 30s
volumes:
  miniflux-db:




Note: you might want to change following two things in the texts:
  • Ports: default port is 80, you might already used 80 for something else, I would suggest change it to others, such as , 8010. 
    • You might also need to change your VPS's firewall port to allow 8010
  • Default password for user admin.



2 Deploy Template and check dockers running state



3 Visit your miniflux on port 8010



Integrate with your own domain and enable HTTPS

You can find out this traefik.yml file as template for your reverse proxy configuration to integrate your own domain and enable https to your URL:

https://github.com/miniflux/v2/tree/master/contrib/docker-compose


You might need to change following thre highlighted places in following textbox:

version: '3.4'
services:
  traefik:
    image: "traefik:v2.3"
    container_name: traefik
    command:
      - "--providers.docker=true"
      - "--providers.docker.exposedbydefault=false"
      - "--entrypoints.websecure.address=:443"
      - "--certificatesresolvers.myresolver.acme.tlschallenge=true"
      - "--certificatesresolvers.myresolver.acme.email=[email protected]"
      - "--certificatesresolvers.myresolver.acme.storage=/letsencrypt/acme.json"
    depends_on:
      - miniflux
    ports:
      - "443:443"
    volumes:
      - "./letsencrypt:/letsencrypt"
      - "/var/run/docker.sock:/var/run/docker.sock:ro"
  miniflux:
    image: ${MINIFLUX_IMAGE:-miniflux/miniflux:latest}
    container_name: miniflux
    depends_on:
      - db
    expose:
      - "8080"
    environment:
      - DATABASE_URL=postgres://miniflux:[email protected]/miniflux?sslmode=disable
      - RUN_MIGRATIONS=1
      - CREATE_ADMIN=1
      - ADMIN_USERNAME=admin
      - ADMIN_PASSWORD=test123
      - BASE_URL=https://rss.51sec.org
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.miniflux.rule=Host(`rss.51sec.org`)"
      - "traefik.http.routers.miniflux.entrypoints=websecure"
      - "traefik.http.routers.miniflux.tls.certresolver=myresolver"
  db:
    image: postgres:15
    container_name: postgres
    environment:
      - POSTGRES_USER=miniflux
      - POSTGRES_PASSWORD=secret
    volumes:
      - miniflux-db:/var/lib/postgresql/data
    healthcheck:
      test: ["CMD", "pg_isready", "-U", "miniflux"]
      interval: 10s
      start_period: 30s
volumes:
  miniflux-db:

Of course, rss.51sec.org will need to point to your this vps 's public ip address. This can be done by adding a new A record in your DNS administratration center, such as Cloudflare.
