Hi,
I'm working on creating some provisioning code to create and delete stacks
in EC2. So far I have four pieces of code which I'm working on
1. An ansible role which creates infrastructure like a VPC and security
groups
2. An ansible role which creates stack layers, the same code can be run
multiple times with a layer name to make multiple layers of a stack
3. An ansible role which tears down stack layers, the same code can be run
multiple times with a layer name to remove a particular layer
4. An ansible role which deletes infrastructure like the VPC and security
groups
I also am passive a variable to the stack creation called aws_environment
which I can use to manage multiple stack at once (i.e. have a staging,
development and production stack as different environment)
1 and 2 were more difficult than I an anticipated but I got working fairly
well but I'm totally stuck on 3 and need some help.
I'm at a step in the 3rd role where I want to detach instances from the
load balancer. I need to be able to generate a list of instances in the
matrix of Environment X Layer, where Environment is passed as a variable to
ansible-playbook and the layer name is a variable defined as layer_name for
each call of the delete_layer role.
I need to then use that list to remove the instance from the ELB like so:
*- name: "{{ layer_name }} layer - Detach instance from ELB"*
* local_action:*
* module: ec2_elb*
* state: absent*
* region: "{{ aws_region }}"*
* instance_id: "{{ item.id }}" <-- HOW DO I GET THIS*
* ec2_elbs: "{{ layer_name }}" <-- The ELB for the layer is named the
same as the layer itself*
* with_items: **STUCK***
* when: attach_elb == True*
Can I perhaps make a fact that I can then iterate over somehow?
