REGION=us-east-1
ZONES=us-east-1a,us-east-1b
CLUSTER_NAME=example
BASE_DOMAIN=example.com
AWS_CREDS="$HOME/.aws/credentials"
PULL_SECRET="$HOME/pull-secret"

hypershift create cluster aws \
--name $CLUSTER_NAME \
--node-pool-replicas=3 \
--base-domain $BASE_DOMAIN \
--pull-secret $PULL_SECRET \
--aws-creds $AWS_CREDS \
--region $REGION \
--zones $ZONES

The --zones flag is also available on the hypershift create infra aws command used to create infrastructure separately.

The following per-zone infrastructure is created for all specified zones:

• Public subnet
• Private subnet
• NAT gateway
• Private route table (Public route table is shared across public subnets)

Two NodePool resources are created, one for each zone. The NodePool name is suffixed by the zone name. The private subnet for zone is set in spec.platform.aws.subnet.id.
