How to run

guacd server

To connect to remote servers (RDP/SSH/VNC) you need a guacd service.
If you already use Apache Guacamole, you can use your existing guacd.
Alternatively use guacd in a standalone container or in a docker-compose stack

docker cmd example

docker run -it --rm -p 8080:80 -p 8443:443 guacozy/guacozy-server

This will start a container with sqlite database (destroyed after container is down)
In order to actually use it, it should be able to connect to guacd service
You can run guacd as container:

docker run --name guacdlocal --restart always -d -p 4822:4822 linuxserver/guacd

This will start guacd container with restart policy always, name guacdlocal and published port 4822 in detached (-d) mode

Make sure to add a guacd server in AppSettings (or change the default guacdserver) to include this
Hostname: $IP, Port: 4822

Where $IP is address of your docker machine (127.0.0.1 will not do, as container will try to connect to itself)

You can find other builds of guacd containers here: 1 2 3

docker-compose example

This example of a composite with 3 services:

• guacozy-server
• guacd
• postgresql

# docker-compose.yml

version: '3'  
services:
  server:
    image: guacozy/guacozy-server
    restart: always
    depends_on:
      - db
    environment:
      - DJANGO_SECRET_KEY=abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz
      - FIELD_ENCRYPTION_KEY=qjq4ObsXMqiqQyfKgD-jjEGm4ep8RaHKGRg4ohGCi1A=
      - DJANGO_DB_URL=postgres://postgres@db:5432/postgres
      - DJANGO_ALLOWED_HOSTS=*
    ports:
      - 10080:80
      - 10443:443
  guacd:
    image: guacamole/guacd
    restart: always
  db:
    image: postgres:10.4-alpine
    restart: always
    volumes:
    - postgres-data:/var/lib/postgresql/data
volumes:
  postgres-data:

Environment variables:

DEBUG : Django DEBUG mode

DJANGO_ALLOWED_HOSTS: Let's you specify allowed hosts to prevent host header attacks (Read more)

DJANGO_SECRET_KEY : random string used for hashing (50 chars)

FIELD_ENCRYPTION_KEY - encryption key which will be used to encrypt passwords in database

If you don't specify FIELD_ENCRYPTION_KEY, default will be used (bad idea).
If you use with one key and later change - your stored passwords will not work

After you start, generate one with
./manage.py generate_encryption_key

In docker compose:
docker-compose exec server ./manage.py generate_encryption_key

If key is not provided, on container start you will be notified and a new key will be generated
You can use it, as suggested value is unique on every container start

DJANGO_TIME_ZONE : timezone (e.g. Europe/Vilnius)

DJANGO_DB_URL : DB URL - read at django-environ documentation

SUPERUSER_NAME,SUPERUSER_EMAIL,SUPERUSER_PASSWORD : use these if you want default admin to have specified values

If you don't specify these values, user admin with password admin and email admin@example.com wiil be created.
You can always change admin's email/password later, however if you ever delete "admin" user it will be recreated on next startup.
So if you are unhappy with admin username, specify just it (you can specify name/email and skip password)

Notes

SSL

Container exposes ports TCP/80 and TCP/443 If you want Guacozy to be accessible only via HTTPS, do not map port 80
If SSL certificate is not provided, a new one is generated on every start.

You can provide your certificates by bind mounting a directory to /ssl/ and providing your certificates
Note that certificates are used by Nginx, so it means that your certificate and CA chain certificates has to be concatenated in one file

cat certificate.crt ca.crt > cert.crt

Certificates has to be in these locations:

/ssl/cert.crt  
/ssl/cert.key

Example how to mount when using docker command line

docker run -it --rm -p 10080:80 -p 10443:443 -v ./myssldir:/ssl guacozy/guacozy-server

Example how to mount when using docker-compose

services:
  server:
    image: guacozy/guacozy-server
    volumes:
      - ./myssldir:/ssl
      - staticfiles:/app/staticfiles/

or you can make automatically generated certificates static by providing a volume to /ssl path

services:
  server:
    image: guacozy/guacozy-server
    volumes:
      - ssl:/ssl
...
volumes:
  ssl:
