Docker Node Support


Provided below is some information for helping setup and use Docker nodes within a CORE scenario.


Debian Systems

sudo apt install

RHEL Systems


Custom configuration required to avoid iptable rules being added and removing the need for the default docker network, since core will be orchestrating connections between nodes.

Place the file below in /etc/docker/docker.json

	"bridge": "none",
	"iptables": false

Group Setup

To use Docker nodes within the python GUI, you will need to make sure the user running the GUI is a member of the docker group.

# add group if does not exist
sudo groupadd docker

# add user to group
sudo usermod -aG docker $USER

# to get this change to take effect, log out and back in or run the following
newgrp docker

Image Requirements

Images used by Docker nodes in CORE need to have networking tools installed for CORE to automate setup and configuration of the network within the container.

Example Dockerfile:

FROM ubuntu:latest
RUN apt-get update
RUN apt-get install -y iproute2 ethtool

Build image:

sudo docker build -t <name> .
