+++ This bug was initially created as a clone of Bug #1716548 +++ Description of problem: IPI installation with AWS. If you change the default configuration to increase the number of workers, the installer chooses an AZ that doesnt support the instance type. Version-Release number of the following components: rpm -q openshift-ansible rpm -q ansible ansible --version How reproducible: can be reproduced Steps to Reproduce: 1. Create an install config Example: ./openshift-install create install-config --dir=second select us-west-2 as the region. 2.Edit install-config.yaml and change the number of workers from 3 to 4 compute: - hyperthreading: Enabled name: worker platform: {} replicas: 4 3. Run the installation ./openshift-install create cluster --dir=second 4. It only creates 3 workers and not 4. Actual results: oc get machinesets -n openshift-machine-api NAME DESIRED CURRENT READY AVAILABLE AGE second-hb7vq-worker-us-west-2a 1 1 1 1 87m second-hb7vq-worker-us-west-2b 1 1 1 1 87m second-hb7vq-worker-us-west-2c 1 1 1 1 87m second-hb7vq-worker-us-west-2d 1 1 87m $ oc get machines -n openshift-machine-api NAME INSTANCE STATE TYPE REGION ZONE AGE second-hb7vq-master-0 i-0ba4c5c0a949af07b running m4.xlarge us-west-2 us-west-2a 99m second-hb7vq-master-1 i-0a1ed6818c4091dda running m4.xlarge us-west-2 us-west-2b 99m second-hb7vq-master-2 i-0c100e6e76d64c8fa running m4.xlarge us-west-2 us-west-2c 99m second-hb7vq-worker-us-west-2a-5qwgp i-01a26741af6e0dac5 running m4.large us-west-2 us-west-2a 97m second-hb7vq-worker-us-west-2b-qt7mx i-09bdde677ace6cfd8 running m4.large us-west-2 us-west-2b 97m second-hb7vq-worker-us-west-2c-fb9vh i-03dfe21426a3a029f running m4.large us-west-2 us-west-2c 97m second-hb7vq-worker-us-west-2d-xm6dh m4.large us-west-2 us-west-2d 97m Machine is not running.
