How do I deploy Firebase Database Security rules using the command line?

问题

In older versions of Firebase, we could add a rules section to our firebase.json file, and upload new security rules on every deploy.

How do we use the firebase-tools v3 command-line tools to deploy database security rules?

This page says that it's possible: "Rules for Firebase Storage"

This page hints that the command line tools can do it, but firebase --help and firebase deploy --help don't seem to hint at how to do it? (Apologies if I missed it...)

(related: where is the canonical doc for everything that can go into firebase.json? I found it on the old Firebase site, but can't find it via search on the new docs.)

Thanks!

You can use firebase deploy --only database if you only want to update database rules. It will overwrite your existing rules.

You can check out Firebase CLI Reference for more info

You can use firebase deploy or firebase deploy --only database from the command line, BUT most important:

Please note hereunder firebase.json format: The "rules" entry is under "database" entry.

It was taken from Firebase Sample code.

{
  "database": {
    "rules": "database-rules.json"
  },
  "hosting": {
    "public": "./",
    "ignore": [
      "firebase.json",
      "database-rules.json",
    ]
  }
}

To deploy a new set of security rules, add a rules top-level key to your firebase.json.

Example firebase.json file:

{
  "rules": "firebase_rules.json",
  "hosting": {
    "public": "doc",
    "ignore": [
      "firebase.json",
      "**/.*",
      "**/node_modules/**"
    ]
  }
}

The firebase_rules.json is a JSON file that contains the security rules. Here's an example:

{
  "rules": {
    ".read": false,
    ".write": false
  }
}

When you run firebase deploy, it will send the contents of firebase_rules.json to the server, replacing/updating any rules configurations.
