Fork of the good work done here: https://github.com/matthewkrupnik/docker-firestore-emulator-with-ui

Slightly modified to only run firestore with the UI for my own use-case.

Container is running Alpine linux with Node LTS, Bash, and Openjdk11 installed. Container installs the firebase-toolkit from npm. It also installs the firestore and turns on the UI.

At some stage, I'll push this image to Docker Hub, but for now, you can build and tag the image by running the below:

~$ docker build https://github.com/jordanbalsamo/docker-firestore-emulator-with-ui.git#master -t firestore-emulator-ui

Note: the rest of the commands in this README will assume you've built the image using this method.

Run the container with firestore default ports

~$ docker run -p 8080:8080 -p 4000:4000 jordanbalsamo/firestore-emulator-ui

Run the container with custom ports

~$ docker run -e FIRESTORE_PORT=8200 -p 8200:8200 -p 4000:4000 firestore-emulator-ui

By default, the ports are set as follows:

• FIRESTORE_PORT default to 8080
• UI_PORT default to 4000

To modify the default ports, see above Run the container with custom ports.

• firestore.indexes.json is found at /firebase/firestore.indexes.json
• firestore.rules is found at /firebase.rules
• functions need to be loaded at /firestore/functions

To use firestore emulator the environment variable needs to be set.

FIRESTORE_EMULATOR_HOST="localhost:8080" # remember to change this if customising default ports
