OK. This is covered in the official documentation somewhere but I can't remember where. I can remember that it took me a while to get it going. Let me try to remember:

You have to define GUACAMOLE_HOME environment variable to a custom location within the container e.g. /guachome,

Then you have to create a volume (e.g. a local folder) that is put inside the container as /guachome and within /guachome you have to create a subfolder for the extensions e.g. /guachome/extensions.

so partly the guacmole: section of the docker-compose.yml will look like this:

# guacamole
  guacamole:
    container_name: guacamole_compose
    depends_on:
    - guacd
    - postgres
    environment:
    ...
    ...
    ...
      GUACAMOLE_HOME: /guachome
    volumes:
      - ./guachome:/guachome
      - ./extensions:/guachome/extensions
    ...

Then you have to create guachome/guacamole.properties that defines enable-environment-properties to true. That allows you to tell the container that it should use a new Guacamole home dire based on the GUAC_HOME variable.

#guacamole.properties
enable-environment-properties: true

Then I have a subfolder extensions e.g. with branding.jar:

extensions/
extensions/branding.jar

All put together should work. I only have a non productive version lying arround but my docker-compose.yml finally looked like this:

version: '2.0'

  guacnetwork_compose:
    driver: bridge

    networks:

    restart: always

  nginx:
   container_name: nginx_guacamole_compose
   restart: always
   image: nginx
   volumes:

   - ./nginx/ssl/self-ssl.key:/etc/nginx/ssl/self-ssl.key:ro

   links:
   - guacamole
   networks:
     guacnetwork_compose:
   command: /bin/bash -c "nginx -g 'daemon off;'"

local guachome folder

guachome/
guachome/extensions
guachome/guacamole.properties

local extensions folder

extensions/
extensions/branding.jar

I think that could point you in the right direction.

environment variable GUACAMOLE_HOME and a volume was enough to work, here my full yml file:
