Docker and Docker Compose Installation and Usage Guide

Installing Docker

For Ubuntu/Linux:

1) Update your existing list of packages:

sudo apt update

2) Next, install a few prerequisite packages which let apt use packages over HTTPS:

sudo apt install apt-transport-https ca-certificates curl software-properties-common

3) Then add the GPG key for the official Docker repository to your system:

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

4) Add the Docker repository to APT sources:

sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu focal stable"

5) Finally, install Docker:

sudo apt install docker.io

Running a Docker Compose File

1) Install docker Compose

apt-install docker-compose

2) Create a docker-compose.yml file in your desired directory.

version: '3'

services:
  nginx-proxy:
    image: jwilder/nginx-proxy:alpine
    container_name: nginx-proxy
    restart: unless-stopped
    volumes:

  unifi:
    image: linuxserver/unifi-controller
    container_name: unifi
    restart: unless-stopped
    environment:
      - VIRTUAL_HOST={subdomain}
      - VIRTUAL_PORT=8443
      - VIRTUAL_PROTO=https
      - LETSENCRYPT_HOST={subdomain}

    volumes:
      - /var/docker/unifi:/config
    ports:
      - "3478:3478/udp"
      - "8080:8080"

  nginx-letsencrypt:
    image: jrcs/letsencrypt-nginx-proxy-companion
    container_name: nginx-letsencrypt
    restart: unless-stopped

    volumes:
      - /var/docker/nginx-proxy/certs:/etc/nginx/certs:rw
      - /var/run/docker.sock:/var/run/docker.sock:ro

docker-compose up -d
