# Introduction
Caddy v2 is the easiest reverse proxy ever! You'll be able to host multiple dockerized applications with one VM and one domain name! I learned from [DoTheEvo ](https://github.com/DoTheEvo/selfhosted-apps-docker/tree/master/caddy_v2 ), but their guide assumes you already installed docker and docker-compose. From my [A-Z guide ](https://github.com/StarWhiz/docker_deployment_notes/tree/master/initial%20ubuntu%20setup )... you be handheld from the beginning. In addition to the app specific guides on DoTheEvo's page I also added some of my own!
Anyways please start with the [A-Z Guide ](https://github.com/StarWhiz/docker_deployment_notes/tree/master/initial%20ubuntu%20setup ) guide below which will take you from base Ubuntu 20.04 to having docker, docker-compose, caddy v2 installed.
## A to Z Guide (Start Here)

After you finish the A-Z guide. You can then follow application specific guides from me below. Or from [DoTheEvo ](https://github.com/DoTheEvo/selfhosted-apps-docker ) for other apps.

# Quick-References and Notes
## Most Commonly Used Commands
```
docker exec -w /etc/caddy caddy caddy reload
docker network create caddy_net # Only need to do this once on new VMs (From Step 9 of A-Z Guide)
```
Use this command everytime you make changes to Caddyfile.
```
docker exec -t -i CONTAINERNAME /bin/bash
docker exec -t -i CONTAINERNAME /bin/sh
```
Commands to enter a container's shell. Use bash first, if that doens't work try sh.
## Commonly used Docker Specific Commands
```
docker container ls # list all running containers
docker container ls -a # list all containers even stopped ones
docker container rm # remove container
docker container kill # kill a running container
docker system prune # Remove all unused docker: containers, images, networks and volumes to free up space
docker container prune # Similar to system prune but only targets containers.
### While inside app specific folder
docker-compose restart # restart docker stack for application
docker-compose down # turn off application
docker-compose up # turn on application with logs. CTRL+C to exit
docker-compose up -d # turn on application without logs and runs in background
docker-compose pull # update application
```
## Commonly added lines added to app specific docker-compose.yml files
```
services:
exampleapp:
### Commonly Added To Applications
container_name: app-name # A container name for Caddyfile to reference to
# with reverse-proxy app-name:80 for example
restart: unless-stopped # When your VM restarts the docker-container will start automatically
ports:
- "8080:80" # Usually reverse-proxy will do. Sometimes there are cases where you need ports open.
# Here we open port 8080 on the host machine. It maps to port 80 inside the docker container.
volumes:
- ./folder:/some/pathinsidecontainer/folder # Changes made in ./folder will appear inside the path mentioned
### The Caddy Network
networks:
default:
external:
name: caddy_net
### Example .env variables in docker-compose.yml
${VARIABLE_A}
### Example variable in .env
VARIABLE_A=My_SQL_PASSWORD
```
## Common UFW commands
```
sudo ufw status numbered #numbered list of all ufw rules
sudo delete 3 #delete rule #3 from ufw rules
sudo ufw enable
sudo ufw disable
sudo ufw allow 21/tcp # Open TCP port 21
sudo ufw allow 21/udp # Open UDP port 21
sudo ufw allow 21 # Open UDP & TCP for port 21.
```
## Caddy v2 References
To prevent automatic HTTPS on Caddy 2, append http:// to your CaddyFile Entries. Example Below.
```
http://subdomain.yourdomain.com {
reverse_proxy wordpress:80
}
```
You can reverse proxy to IP Address + Port instead of by container name.
```
subdomain.yourdomain.com {
reverse_proxy 192.168.16.5:8080
}
```
## Other Linux Commands
Check size of current directory
```
sudo du -sh ./
```
Check total disk usage
```
sudo df -h ./
```
