### Intro
This guide references: https://jitsi.github.io/handbook/docs/devops-guide/devops-guide-docker as the original source for installation.

Currently this method is very basic and hosts an instance of jitsi without video recording and without authentication. Anyone with link can start a video conference. You would have to play around with .env and refer to the documentation to do these things.

### Minimum File Structure
```
/home/
└── ~/
    └── docker/
        └── jitsi/
            ├── docker-compose.yml
			├── .env
			├── gen-passwords.sh
```

### Add to Caddyfile (from ~/docker/caddy)
Remember to `docker exec -w /etc/caddy caddy caddy reload` after editing your Caddyfile.
```
meet.example.com {
	reverse_proxy jitsi-web:80
}
```

### docker-compose.yml
```

### .env
Here you want to edit the PUBLIC_URL to match your subdomain.example.com

Then after saving this, run the script called ./gen-passwords.sh to generate the 6 passwords in the first few lines.
```
# shellcheck disable=SC2034

# Security
#
# Set these to strong passwords to avoid intruders from impersonating a service account
# The service(s) won't start unless these are specified
# Running ./gen-passwords.sh will update .env with strong passwords
# You may skip the Jigasi and Jibri passwords if you are not using those
# DO NOT reuse passwords
#

### gen-passwords.sh
Make your .env file first before running this script. 
To run this script make sure you do a `chmod +x gen-passwords.sh'
then do a `./gen-passwords.sh`.
```
#!/bin/bash

function generatePassword() {
    openssl rand -hex 16
}

JICOFO_COMPONENT_SECRET=$(generatePassword)
JICOFO_AUTH_PASSWORD=$(generatePassword)
JVB_AUTH_PASSWORD=$(generatePassword)
JIGASI_XMPP_PASSWORD=$(generatePassword)
JIBRI_RECORDER_PASSWORD=$(generatePassword)
JIBRI_XMPP_PASSWORD=$(generatePassword)

sed -i.bak \
    -e "s#JICOFO_COMPONENT_SECRET=.*#JICOFO_COMPONENT_SECRET=${JICOFO_COMPONENT_SECRET}#g" \
    -e "s#JICOFO_AUTH_PASSWORD=.*#JICOFO_AUTH_PASSWORD=${JICOFO_AUTH_PASSWORD}#g" \
    -e "s#JVB_AUTH_PASSWORD=.*#JVB_AUTH_PASSWORD=${JVB_AUTH_PASSWORD}#g" \
    -e "s#JIGASI_XMPP_PASSWORD=.*#JIGASI_XMPP_PASSWORD=${JIGASI_XMPP_PASSWORD}#g" \
    -e "s#JIBRI_RECORDER_PASSWORD=.*#JIBRI_RECORDER_PASSWORD=${JIBRI_RECORDER_PASSWORD}#g" \
    -e "s#JIBRI_XMPP_PASSWORD=.*#JIBRI_XMPP_PASSWORD=${JIBRI_XMPP_PASSWORD}#g" \
    "$(dirname "$0")/.env"
```

Finally after modifying your Caddyfile and making the 3 files and running gen-passwords.sh. You're ready to do a `docker-compose up -d` inside the jitsi directory to turn it on.
