In this session, we will have a hands-on hackZone with a variety of open source content to choose from and build cloud-native apps. For example, use the Docker container platform along with pre-built Mainframe official docker images such as blockchain with Hyperledger Composer and Fabric, programming languages (Python, Javascript, Java, C/C++, Go, Ruby, php, etc), databases (postgres, redis, cassandra, Db2, etc), Node.js, Tomcat, memcached, haproxy, httpd, openjdk, maven, rabbitmq, solr, nginx and many others. Play on your own or create a team to hack on a project using the Docker platform and Linux as the central theme. We encourage you to think of an idea before coming to the session and show off what you can build. Even-though it is better to know about Docker before joining the session, anyone can join in and participate.
