+**Note:** if you're adding either the `--rpc-url` or `--fork-url` flag to your forge command and the RPC endpoint you're pointing to is on host, you should use http://host.docker.internal:8545 instead of http://localhost:8545 as the value. See Docker's networking docs [here](https://docs.docker.com/desktop/networking/#i-want-to-connect-from-a-container-to-a-service-on-the-host).
