Virtual Hosts on nginx (CSC309)

When hosting our web applications, we often have one public IP address (i.e., an IP address visible to the outside world) using which we want to host multiple web apps. For example, one may wants to host three different web apps respectively for example1.com, example2.com, and example1.com/images on the same machine using a single IP address.

How can we do that? Well, the good news is Internet browsers

apiVersion: apps/v1
kind: Deployment
metadata:
  name: elasticsearch
spec:
  selector:
    matchLabels:
      app.kubernetes.io/name: elasticsearch
  template:

Install Kubernetes Dashboard

kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.2.0/aio/deploy/recommended.yaml

Patch the dashboard to allow skipping login

kubectl patch deployment kubernetes-dashboard -n kubernetes-dashboard --type 'json' -p '[{"op": "add", "path": "/spec/template/spec/containers/0/args/-", "value": "--enable-skip-login"}]'

Create a .sh file - eg. docker-install.sh and paste following:

#!/bin/bash

sudo apt-get install -y apt-transport-https ca-certificates curl software-properties-common
curl -fsSL get.docker.com -o get-docker.sh
sudo sh get-docker.sh
sudo usermod -aG docker $USER

Create NFS Volumes:

Creating the NFS Volume:

$ docker volume create --driver local \
  --opt type=nfs \
  --opt o=addr=192.168.1.115,uid=1000,gid=1000,rw \
  --opt device=:/mnt/volumes/mysql-test \
  mysql-test-1

Working on remote Docker Host using docker context

SSH keys on Windows

In order to use remote Docker host, as a prerequisite you need SSH enabled (required login using SSH keys).

Generate or find your public SSH key

Running Minecraft Server using Docker (and docker-compose)

With over 126 million monthly users, 200 million games sold & 40 million MAU, Minecraft still remains one of the biggest games on the planet.

Why minecraft inside Docker?

for fun of course! :)
can be run locally for your kids
you can run it on popular and low-cost Rasperry PI inside your home and/or in the cloud

Apple M1 workaround for Docker

Prerequisites

You need a dedicated Linux machine (linux-vm) (in the cloud or on your VPS, or bare-metal) with Docker installed and SSH enabled (required login using SSH keys).

Workaround for people who have SSH access to a docker installed linux machine

Install go (pre-compiled binaries at https://golang.org/dl/

(Edit: there are no Darwin arm64 yet, You need to compile or use Homebrew...)
