Corda on Docker

Docker 17.09 and up is required for this Dockerfile.

Docker configuration files to create and spin up Docker images for a few Corda Nodes (banka/bankb/bankc), Networkmap, Notary and one CordApp.

The docker image is based on Alpine/OpenJDK (https://hub.docker.com/_/openjdk/)

Usage (automatic way - 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/Networkmap/Notary
• docker-compose up - to spin up all Corda containers (Nodes + Networkmap + Notary)
• docker exec -it banka /bin/sh - to log in to one of the running Node containers
• docker exec -it networkmap /bin/sh - to log in to the running Networkmap container

Corda configuration

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

If you need to modify Corda parameters (node or/and networkmap) change their configuration file(s) and restart container:

For Corda node (i.e. banka):

• modify files/corda-banka.conf
• restart Corda node: docker restart banka

For Networkmap node:

• modify files/corda-networkmap.conf
• restart Corda networkmap: docker restart networkmap

Show installed CordApps

In your web browser open:

• http://localhost:10024 (for banka)
• http://localhost:10034 (for bankb)

etc

Issues

If you get the following message: <containername> exited with code 137 it's likely because the Linux OOM killer is getting triggered inside of running Docker instance. Please adjust memory size for Docker environment: On MacOS: https://docs.docker.com/docker-for-mac/#memory On Windows: https://docs.docker.com/docker-for-windows/#advanced

TODO

• add more to README.md (how to customise the build, potential manual spin up without docker compose)
