Static Sites With Minio and S3www

#minio #selfhosting #staicpages

Hi! If you read my last post, you already know how to host your static pages on Azure, but among us there are people who don't like to use the "big companies" solution and prefer to host things themselves under their own roof. Here is a solution for them.

This solution uses two open source software. One is Minio which is a S3 compatible storage made with GO language and 2nd is s3www which is simple server also made with GO which uses S3 storage as storage for static pages.

Oh, and I also use Traefik which is a reverse proxy server. It will also be responsible for generating Let's Encrypt certificates. This last one can be skipped if you want to use whatever proxy you already have, but for me this was the easiest to configure.

Prerequisites

As prerequisite you will need to install Docker and docker compose for which links to guides i mention bellow.

You can freely skip this one if you already have docker installed on you computer (or server) and go to the next step.

Setup Traefik

First set up the reverse proxy (Traefik mentioned above). This will route traffic to your Docker services and create certificates for the secure HTTP protocol using Let's Encrypt.

Add the following content to your docker-compose.yml somewhere on your server e.g. ~/docker/traefik.

version: '2'

services:
  proxy:
    image: traefik
    command:
      # --configFile=/traefik.yml
      - "--api.dashboard=true"
      - "--api.insecure=true"
      - "--log.level=DEBUG"
      - "--providers.docker=true"
      - "--providers.docker.exposedbydefault=false"
      - "--entrypoints.web.address=:80"
      - "--entrypoints.websecure.address=:443"
      - "--certificatesresolvers.le.acme.httpchallenge=true"
      - "--certificatesresolvers.le.acme.httpchallenge.entrypoint=web"
      #- "--certificatesresolvers.myresolver.acme.caserver=https://acme-staging-v02.api.letsencrypt.org/directory"
      - "--certificatesresolvers.le.acme.email=<your@email.tld>" # change to your email used for generating new Let's encrypt ceritificates
      - "--certificatesresolvers.le.acme.storage=/letsencrypt/acme.json" # here are stored certificates informations
      - "--accesslog=true"
    restart: unless-stopped
    networks:
      - frontend
    ports:
      - "80:80"
      - "443:443"
      - "8080:8080"
    volumes:
      - /etc/localtime:/etc/localtime:ro
      - /var/run/docker.sock:/var/run/docker.sock:ro
      - ./letsencrypt:/letsencrypt
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.traefik.entrypoints=web"
      - "traefik.http.routers.traefik.rule=Host(`traefik.your-domain.tld`)" # Change this to your domain
      - "traefik.http.middlewares.traefik-websecure-redirect.redirectscheme.scheme=websecure"
      - "traefik.http.routers.traefik.middlewares=traefik-websecure-redirect"
      - "traefik.http.routers.traefik-secure.entrypoints=websecure"
      - "traefik.http.routers.traefik-secure.rule=Host(`traefik.your-domain.tld`)" # Change this to your domain
      - "traefik.http.routers.traefik-secure.tls=true"
      - "traefik.http.routers.traefik-secure.tls.certresolver=le"
      - "traefik.http.routers.traefik-secure.service=api@internal"
      - "traefik.http.services.traefik.loadbalancer.server.port=8080"

networks:
  frontend:
    external: true
Enter fullscreen mode Exit fullscreen mode

To start it run following command

cd ~/docker/traefik
docker-compose up -d
Enter fullscreen mode Exit fullscreen mode

Cool, from now on you've got reverse proxy running for all your services. Open http://traefik.your-domain.tld:8080 to see dashboard.

If you wish, you can disable public access to the Dashboard by setting a firewall rule to only allow connections from IP addresses you know. (Don't use this if your external IP address is dynamic)

Another way is to comment the following line- "8080:8080" in docker-compose.yml file.

Setup Minio

Next you will need to configure Minio, as you will need a place to put your website files. So, create a new folder ~/docker/minio that will contain your server configuration and add the following content to your docker-compose.yml.

version: '3.7'

networks:
  frontend:
    external: true

services:
  minio:
    image: minio/minio:RELEASE.2020-08-07T01-23-07Z
    restart: unless-stopped
    networks:
      - frontend
    volumes:
      - ./data:/data
    environment:
      MINIO_ACCESS_KEY: <YOUR-ACCESS-KEY>
      MINIO_SECRET_KEY: <YOUR-SECRET-KEY>
    command: server /data
    healthcheck:
      test: ["CMD", "curl", "-f", "http://localhost:9000/minio/health/live"]
      interval: 30s
      timeout: 20s
      retries: 3
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.minio.entrypoints=web"
      - "traefik.http.routers.minio.rule=Host(`s3.your-domain.tld`)"
      - "traefik.http.middlewares.minio-websecure-redirect.redirectscheme.scheme=https"
      - "traefik.http.routers.minio.middlewares=minio-websecure-redirect"
      - "traefik.http.routers.minio-secure.entrypoints=websecure"
      - "traefik.http.routers.minio-secure.rule=Host(`s3.your-domain.tld`)"
      - "traefik.http.routers.minio-secure.tls=true"
      - "traefik.http.routers.minio-secure.tls.certresolver=le"
      - "traefik.http.routers.minio.service=minio"
      - "traefik.http.services.minio.loadbalancer.server.port=9000"
      # Don't need to use when your container use only one network but it is very important when you have multiple networks with container
      - "traefik.docker.network=frontend"
Enter fullscreen mode Exit fullscreen mode

Before you can start it you have to change some rows there.

  1. Update your secret and access keys 
    environment:
      MINIO_ACCESS_KEY: <YOUR-ACCESS-KEY>
      MINIO_SECRET_KEY: <YOUR-SECRET-KEY>
Enter fullscreen mode Exit fullscreen mode
  1. Change address to your domain in labels 
- "traefik.http.routers.minio.rule=Host(`s3.your-domain.tld`)"
- "traefik.http.routers.minio-secure.rule=Host(`s3.your-domain.tld`)"
Enter fullscreen mode Exit fullscreen mode

this will tell the Traefik on which domain your service will run and then he can requsest for new certificate.

All the magic is in labels section

labels:
  # Enable traefik for service
  - "traefik.enable=true"
  # Listen on HTTP :80
  - "traefik.http.routers.minio.entrypoints=web"
  # Domain for HTTP
  - "traefik.http.routers.minio.rule=Host(`s3.your-domain.tld`)"
  # Redirect to HTTPS
  - "traefik.http.middlewares.minio-websecure-redirect.redirectscheme.scheme=https"
  - "traefik.http.routers.minio.middlewares=minio-websecure-redirect"
  # Setting for HTTPS entrypoint
  - "traefik.http.routers.minio-secure.entrypoints=websecure"
  - "traefik.http.routers.minio-secure.rule=Host(`s3.your-domain.tld`)"
  - "traefik.http.routers.minio-secure.tls=true"
  # Here is configuration for Cert resolver - We are using Lets Encrypt
  - "traefik.http.routers.minio-secure.tls.certresolver=le"
  # Which service and port it using
  - "traefik.http.routers.minio.service=minio"
  - "traefik.http.services.minio.loadbalancer.server.port=9000"
  # Network for running docker services
  - "traefik.docker.network=frontend"
Enter fullscreen mode Exit fullscreen mode

You copy this labels to your next services and change it based on you needs.

Start minio

cd ~/docker/minio
docker-compose up -d
Enter fullscreen mode Exit fullscreen mode

Navigate to https://s3.your-domain.tld and you will se Minio's login page. To login use your ACCESS-KEY and SECRET-KEY. In web UI you can do simple things as create new buckets, upload files or set permissions. The default user (the one which is created with first start) is admin, so it have access (R/W) to all buckets you create. It's ok if you using it only for myself, but its not wise but wne you want multiple users? So let me show you how can you create new user ang give it access only to those buckets you want.

Download Minio Client

First of all you will need Minio Client. So download it

wget https://dl.min.io/client/mc/release/linux-amd64/mc
chmod +x mc
./mc --help
Enter fullscreen mode Exit fullscreen mode

On Windows you can donwload it from here https://dl.min.io/client/mc/release/windows-amd64/mc.exe.

Login to server

To login to your server use following command

mc config host add mystorage https://s3.your-domain.tld <YOUR-ACCESS-KEY> <YOUR-SECRET-KEY> --api s3v4
Enter fullscreen mode Exit fullscreen mode

Create user

Let's create our user which will have acces to our bucket with page

mc admin user add home <user-name-or-key> <super-strong-password>
Enter fullscreen mode Exit fullscreen mode

You can create user with any name you want. If you want to login there over web maybe it is better to give it name you can remember, since i want use this user for application i generating for both of them string for example name have 24 characters and password 48. As i said you can use whatever suits your needs better.

Create bucket

Create bucket where you will store your static site files.

mc mb mystorage/<change-this-to-your-bucket-name>
Enter fullscreen mode Exit fullscreen mode

Create bucket policy

Next create policy which will be assigned to user

{
    "Version": "2012-10-17",
    "Statement": [
      {
        "Action": [
          "s3:GetObject",
          "s3:PutObject",
          "s3:DeleteObject",
          "s3:GetBucketLocation",
          "s3:ListBucket",
          "s3:ListAllMyBuckets"
        ],
        "Effect": "Allow",
        "Resource": [
          "arn:aws:s3:::<change-this-to-your-bucket-name>/*"
        ],
        "Sid": "Public"
      }
    ]
  }
Enter fullscreen mode Exit fullscreen mode

Upload policy to server 

mc admin policy add mystorage <policy-name> <policy-name>.json
Enter fullscreen mode Exit fullscreen mode

You can name your fiel with policy to any name you want. I just naming it with same name as my policy.

Apply policy to user 

mc admin policy set mystorage "iso" user=<your-user-name>
Enter fullscreen mode Exit fullscreen mode

This is last thing on our minio server. So we have

  • Minio server
  • Bucket for our page
  • User with policy to Read and Write to this bucket.

Setup s3www

To server static site from minio you will need server, because you cant tell to minio server to use index files (in time i write this i cant find any information about it). In this example i show you how to use s3www.

To server webpage from minio is easy as

s3www -endpoint "https://s3.amazonaws.com" -accessKey "accessKey" \
      -secretKey "secretKey" -bucket "mysite"
Enter fullscreen mode Exit fullscreen mode

But we will need to run it in docker and tell to traefik what it have to do.

Here is docker-compose file i use to hos my sites:

version: "2"

networks:
  frontend:
    external: true

services:
  s3www:
    image: maymeow/s3www:latest
    command:
      - "-endpoint=https:/<change-to-your-s3-address>"
      - "-accessKey=<change-this-to-user-name>"
      - "-secretKey=<change-this-to-password>"
      - "-bucket=<change-this-to-bucket-name>"
      - "-address=0.0.0.0:8080"
    restart: unless-stopped
    networks:
      - frontend
#    ports:
#      - "3000:3000"
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.s3www.entrypoints=web"
      - "traefik.http.routers.s3www.rule=Host(`<chage-this-to-your-page-address>`)"
      - "traefik.http.middlewares.s3www-websecure-redirect.redirectscheme.scheme=https"
      - "traefik.http.routers.s3www.middlewares=gitea-websecure-redirect"
      - "traefik.http.routers.s3www-secure.entrypoints=websecure"
      - "traefik.http.routers.s3www-secure.rule=Host(`<chage-this-to-your-page-address>`)"
      - "traefik.http.routers.s3www-secure.tls=true"
      - "traefik.http.routers.s3www-secure.tls.certresolver=le"
      - "traefik.http.routers.s3www.service=gitea"
      - "traefik.http.services.s3www.loadbalancer.server.port=8080"
      - "traefik.docker.network=frontend"
Enter fullscreen mode Exit fullscreen mode

In <chage-this-to-your-page-address> use just page domain without https:// or http://.

Copy your site to minio

Everything is set so last thig you have to do is to copy your page data to your minio bucket:

cd /path/to/your/site
mc cp -r . cdn/<change-this-to-buckent-name>
Enter fullscreen mode Exit fullscreen mode

Bonus

I showed you how to upload site manually and as bonus here is script for gitlab runner to uppload contend vi CI/CD.

deploy to azure:
  stage: deploy
  image: maymeow/minio-cli
  cache:
    key: themaymeow-com-build
    paths:
      - public
    policy: pull
  dependencies:
    - pages
  script:
    - mc config host add cdn <change-your-s3-address-> $CDN_ACCESS_KEY $CDN_SECRET_KEY --api s3v4
    - cd public
    - mc cp -r . cdn/<change-this-to-buckent-name>
    # Just for visualy check if there are files
    - mc ls cdn/<change-this-to-buckent-name>
  only:
    - master
  tags:
    - docker
    - digitalocean
Enter fullscreen mode Exit fullscreen mode

Don't forget to create variables CDN_ACCESS_KEY with minio user name and CDN_SECRET_KEY with minio user password.

If you have more questions feel free to contact me.

please use something like grammerly.com, missing important words in every 3rd sentence feels like reading something that a 5 year old has written, just a friendly advice

Funny you would say something about 5y old and then misspell in your 1st line "grammerly" :).
