remote-config

This is a lightweight and simple remote config server with a UI for management backed by AWS S3.

The backend API (Go) serves a frontend (Vue) and HTTP endpoints.

I wrote this because I don't want to pay for another service and Firebase doesn't work all the time in web extensions :/

Get Started

1. Create S3 Bucket
2. Build the docker image
3. Deploy the docker image

That's it!

1. Create S3 Bucket

You can create the S3 bucket however you like. Or you can use an existing one.

See AWS's docs if you've never done this before: https://docs.aws.amazon.com/AmazonS3/latest/userguide/creating-bucket.html

2. Build the docker image

Eventually, I'm going to publish this image to docker hub. Until then, build and tag the image yourself:

git clone [email protected]:anime-skip/remote-config.git
docker build . -t my-remove-config

3. Deploy the docker image

You will have to self host this docker image. AWS, Heroku, GoogleCloud, anywhere that supports deploying docker images will work.

Make sure you provide all the environment variables however your hosting provider allows.
