Hmm, that might work. I need to spread the instances over the availability
zones so I have been setting up something like:
instances:
- {subnet: "{{vpc_subnet.private.a}}", count: 3 }
- {subnet: "{{vpc_subnet.private.b}}", count: 3 }
- {subnet: "{{vpc_subnet.private.c}}", count: 3 }
- {subnet: "{{vpc_subnet.private.d}}", count: 1 }
- name: Create instances
ec2:
image: "{{ubuntu_image.ami}}"
region: "{{ec2_region}}"
vpc_subnet_id: "{{item.subnet.id}}"
instance_type: "{{api_proxy_instance_type}}"
assign_public_ip: false
group: "{{security_groups}}"
instance_tags:
Name: "{{env_prefix}}{{instance_name}}"
api_proxy: group
subnet: "{{item.subnet.id}}"
env: "{{env}}"
managed_by: ansible
exact_count: "{{item.count}}"
count_tag:
api_proxy: group
subnet: "{{item.subnet.id}}"
key_name: "{{aws_key_name}}"
wait: yes
register: ec2_proxy
with_items: instances
I looks like using with sequence and (item % 4) to select the availability
zone would then leave the {{item}} to be used a suffix.
I will have to try this. Thanks Benno!
