# Docker (Standalone)

This page describes the configuration of a single Wasp node in combination with Docker.

The docker setup comes preconfigured and should work as is, differing setups might require a different configuration.

In this case the following instructions should be read Running a Node.

## Running a Wasp Node​

### Install and Build Your Node​

To run a Wasp node with Docker you will need to:

1. Check out the project:
git clone https://github.com/iotaledger/wasp.git
1. Switch to the develop branch:
cd waspgit checkout develop
1. Build the main image:
docker build -t wasp-node .

### Default Configuration​

The build process will copy the docker_config.json file into the image, which will be used when the node gets started.

By default, the build process will use -tags rocksdb as a build argument.You can modify this argument
with --build-arg BUILD_TAGS=<tags>.

Depending on the use case, you may need to change the default Hornet configuration. You can do so by editing the docker_config.json file:

"inx": {  "address": "localhost:9029",  "maxConnectionAttempts": 30},

After the build process has finished, you can start your Wasp node by running:

docker run wasp-node

#### Configuration of built images​

After the build process has been completed, you can still inject a different configuration file into a new container by running:

docker run -v \$(pwd)/alternative_docker_config.json:/etc/wasp_config.json wasp-node

You can also add further configuration using arguments:

docker run wasp-node --l1.inxAddress="alt_hornet:9029"

To get a list of all available arguments, run the node with the argument '--help'

docker run wasp-node --help
