 To run integration tests:
 1. Run rippled in standalone node, either in a docker container (preferred) or by installing rippled.
   * Go to the top-level of the `xrpl.js` repo, just above the `packages` folder.
-  * With docker, run `docker run -p 6006:6006 --interactive -t --volume $PWD/.ci-config:/config/ xrpllabsofficial/1.12.0-b1 -a --start`
+  * With docker, run `docker run -p 6006:6006 --interactive -t --volume $PWD/.ci-config:/opt/ripple/etc/ --platform linux/amd64 rippleci/rippled:2.2.0-b3 /opt/ripple/bin/rippled -a --conf /opt/ripple/etc/rippled.cfg`
   * Or [download and build rippled](https://xrpl.org/install-rippled.html) and run `./rippled -a --start`
     * If you'd like to use the latest rippled amendments, you should modify your `rippled.cfg` file to enable amendments in the `[amendments]` section. You can view `.ci-config/rippled.cfg` in the top level folder as an example of this.
 2. Run `npm run test:integration` or `npm run test:browser`
