Setup node on Docker
Before installing Docker, ensure your system meets the minimum requirements before installing the Rootstock node (RSKj). If you already have docker installed. See how to Install the RSKj node using Docker.
Install Docker Desktop Client
Docker Desktop provides an easy and fast way for running containerized applications on various operating systems.
- Mac OSX, Windows
- Linux
- Download and install
- Start the Docker Desktop client
- Login with a Docker Hub free account
- Install Docker Engine Community
- Note that you will need to use
sudofor all docker commands, by default. To avoid this additional steps are required.
- Ensure you have
Rosettainstalled. This is typically pre-installed on recent macOS versions. - Download an x86 JDK build, such as Azul Zulu 17 (x86), to ensure compatibility with x86 based software.
Ensure that docker is running by running the following command - it should run without any errors.
docker ps
You should see the following response:
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

Install RSKj Using Docker
To install a RSKj node using Docker, visit the Docker Hub for installation instructions or use the Reproducible Build.
Logging in RSKj
By default, logs are exclusively directed to a single file. However, if you wish to enable the logging output to STDOUT, you can specify this system property via the command line using -Dlogging.stdout=<LOG_LEVEL>. That command should look something like this:
java -Dlogging.stdout=INFO -cp <classpath> co.rsk.Start --reset --<RSK network>
Regarding the RSKj Docker containers, logs are printed to STDOUT by default, making it easy to view the logs while the container is running. In order to modify this, you can run the Docker container with the environment variable set to a different LOG_LEVEL (For example, DEBUG log level). That command should follow this structure:
docker run -e RSKJ_LOG_PROPS=DEBUG <container-name>
