How to dockerize a customization based off of a stable jitsi-meet docker image

Hi there. I’m just new to jitsi and new to docker.
I’ve made some test changes to the GUI locally using stable version 4857 as a base.
Now i’m wondering how I would go about building a new docker image that incorporates both the base, and my changes.

I’ve downloaded docker jitsi image 4857 … and I’ve been reviewing the docker compose yml. I think the correct approach would be the following:

a) download 4857 stable and make local changes.
b) make
c) test

if it works,
a) git clone https://github.com/jitsi/docker-jitsi-meet.git version 4857
b) edit the docker compose.yml file such that somewhere in the web section for jitsi-meet, I copy my new lib folder and css folder over to the container from the Host.

Would this approach work?
Would this the right approach for just a dev environment or a production deploy too?

Thanks.

I wrote an extended blog post here addressing this question and others, including live-reloading of the front-end using webpack and rapid Docker container rebuilds of the back-end. Hopefully that’s of some use to you or other people looking for examples of Docker deployments.
