firebase-emulators

This is a Firebase Emulator docker image for testing firebase projects

This image contains all current firebase emulators(as of 2020-04-30)

Run from your firebase project root directory:

!!! FOR THIS TO WORK YOU NEED TO COPY THE emulators SECTION OF THIS PROJECT'S firebase.json INTO YOUR OWN !!!.

docker run -it --rm -v $(PWD):/app --name emulators \
  -p9000:9000 -p4400:4400 -p5001:5001 -p8080:8080 \
  -p8085:8085 -p4000:4000 -p4500:4500 \
  wesleyakio/firebase-emulators:8.2.0-2alpine

After startup, direct your browser to http://0.0.0.0:4000/ and check out the beautiful very EXPERIMENTAL Firebase Emulator GUI brought to you by the awesome guys at Firebase.

The command above will map the ports for all the available services, if you don't need them then you can remove some of the the -p port maps. Each port corresponds to a service, you can find port vs service mappings in them in this project's firebase.json

This image assumes you have a dev alias in your .firebaserc file, something like:

{
  "projects": {
    "dev": "project-name-here"
  }
}

This project name is what you will use as the ns in Real Time Database.

---

Realtime Database

If you need to restore your data into the realtime database, you can do so by running:

curl -X PUT -d @your-data.json -H "Content-Type: application/json" http://localhost:9000/.json?ns=project-name-here > /dev/null

project-name-here needs to match the dev aliased project in your .firebaserc file

This image has a Xmx of 3GB for the Realtime database, so you should be able to import JSON files of up to 250MB into the database, if you need more than that then good luck :/
