19. Deploying the overcloud¶

19.1. Prepare Your Environment¶

Source in the undercloud credentials.

source /home/stack/stackrc

Include configuration necessary for the ping test here if requested via the ansible test_ping variable.

DEPLOY_ENV_YAML=/tmp/deploy_env.yaml

Set most service workers to 1 to minimise memory usage on the deployed overcloud when using the pingtest. We use this test over tempest when we are memory constrained, ie the HA jobs.
