Open Tasks

Scaling

test how scaling works with KAPUA on OpenShift

use MariaDB

Currently only H2 database works for KAPUA, because the MySQL/MariaDB driver is not available on the KAPUA images.

Setup done with the following paramters:

  • commons.db.name=$MYSQL_NAME / sampledb
  • commons.db.username=$MYSQL_USER / user
  • commons.db.password=$MYSQL_PASSWORD /password
  • commons.db.jdbcConnectionUrlResolver=mariadb / MariaDB
  • commons.db.jdbc.driver=org.mariadb.jdbc.Driver
  • commons.db.connection.scheme=jdbc:mariab

see eclipse-kapua/kapua#1498

Tested on

  • minishift v1.11.0+d7f374a
  • CDK v3.3.0-1
  • OpenShift CDK 3.7.23
