Intro

In this post we will see how to deploy redis, rabbitmq, postgres and registry.

Deploy docker registry

We will deploy a docker registry

Create folder for registry deployment

mkdir /mnt/auth
mkdir /mnt/registry

Auth folder is for storing the password and registry folder is for storing the images.

Create password for registry

docker run --entrypoint htpasswd httpd:2 -Bbn testuser testpassword

Copy the output to /mnt/auth/registry.password

Registry docker compose

version: '3'

services:
  registry:
    image: registry:2
    networks:
      - traefik-public
    environment:
      VIRTUAL_HOST: registry.yourdomain.com
      REGISTRY_AUTH: htpasswd
      REGISTRY_AUTH_HTPASSWD_REALM: Registry Realm
      REGISTRY_AUTH_HTPASSWD_PATH: /auth/registry.password
    volumes:
      - /mnt/auth:/auth
      - /mnt/registry:/var/lib/registry
    deploy:
      labels:
        - "traefik.enable=true"
        - "traefik.http.routers.registry.rule=Host(`registry.yourdomain.com`)"
        - "traefik.http.services.registry.loadbalancer.server.port=5000"
        - "traefik.http.routers.registry.entrypoints=websecure"
        - "traefik.http.routers.registry.tls=true"
        - "traefik.http.routers.registry.tls.certresolver=leresolver"
        
networks:
  traefik-public:
    external: true

Deploy redis

Redis is an in-memory data structure store, used as a distributed, in-memory key–value database, cache and message broker, with optional durability. Redis supports different kinds of abstract data structures, such as strings, lists, maps, sets, sorted sets, HyperLogLogs, bitmaps, streams, and spatial indices.

Create folder for redis deployment

mkdir /mnt/redis

Redis docker compose

version: "3"
  
services:
  redis-master:
    image: "bitnami/redis:latest"
    ports:
      - "6379:6379"
    environment:
      - REDIS_REPLICATION_MODE=master
      - REDIS_PASSWORD=my_master_password
    volumes:
      - '/mnt/redis:/bitnami'

Deploy postgres

PostgreSQL, also known as Postgres, is a free and open-source relational database management system emphasizing extensibility and SQL compliance.

Create folder for postgres deployment

mkdir /mnt/postgres

Postgres docker compose

version: "3.2"

services:
  postgres:
    image: kartoza/postgis:12.0
    ports:
      - 5432:5432
    volumes:
      - /mnt/postgres:/var/lib/postgresql
    environment:
      POSTGRES_DB: test
      POSTGRES_USER: postgres
      POSTGRES_PASS: my_postgres_password
      --auth: "md5"
      POSTGRES_MULTIPLE_EXTENSIONS: postgis,hstore,postgis_topology

Deploy rabbitmq

RabbitMQ is an open-source message-broker Software that originally implemented the Advanced Message Queuing Protocol and has since been extended with a plug-in architecture to support Streaming Text Oriented Messaging Protocol, MQ Telemetry Transport, and other protocols.

rabbitmq docker compose

version: '3.7'

services:
  rabbitmq:
    container_name: rabbitmq
    image: rabbitmq:management-alpine
    ports:
      - "15672:15672"
      - "5672:5672"

Deploy seq

Seq is the intelligent search, Analysis, and alerting server built specifically for modern structured log data.

Create folder for seq deployment

mkdir /mnt/seq

seq docker compose

version: '3'

services:
  seq:
    image: datalust/seq
    networks:
      - traefik-public
    environment:
      ACCEPT_EULA: "Y"
    volumes:
      - /mnt/seq:/data
    deploy:
      labels:
        - "traefik.enable=true"
        - "traefik.http.routers.seq.rule=Host(`seq.yourdomain.com`)"
        - "traefik.http.services.seq.loadbalancer.server.port=80"
        - "traefik.http.routers.seq.entrypoints=websecure"
        - "traefik.http.routers.seq.tls=true"
        - "traefik.http.routers.seq.tls.certresolver=leresolver"
        
networks:
  traefik-public:
    external: true
