Deploying Corda nodes using docker

1. Install Docker in Ubuntu

Docker 17.09 and up is required for this Dockerfile.

Install docker-ce following this reference: https://docs.docker.com/install/linux/docker-ce/ubuntu/

After docker installed, sudo docker -v should display docker's version

2. Git clone this repository to your workspace

$ git clone https://github.com/consensolabs/syndlend-devops.git

3. Bootstrapping network for corda

The nodes see each other using the network map. This is a collection of statically signed node-info files, one for each node in the network. Most production deployments will use a highly available, secure distribution of the network map via HTTP.

In addition to the network map, all the nodes on a network must use the same set of network parameters. These are a set of constants which guarantee interoperability between nodes. The HTTP network map distributes the network parameters which the node downloads automatically

$ java -jar corda-3.3/network-bootstrapper.jar nodes

the command will generate nodes' directory for us as below:

$ tree -L 2 nodes

4. Using docker compose

• Check Dockerfile and docker-compose.yml (e.g. to adjust version or exposed ports)
• docker-compose build - to build base Corda images for Corda Node
• docker-compose up - to spin up all Corda containers
• docker exec -it Agent /bin/bash - to log in to one of the running Node containers

Corda docker configuration

At the moment java options are put into corda_docker.env. All the others are in Dockerfile/docker_compose.yml

Interaction

You should be able to access all the RPC ports exposed by the nodes through docker containers. You can go ahead and launch the SyndLend client application.
