Hey so I am trying to loop through a dictionary list of servers I want to
create, and want to evaluate some variables based on the iteration I am on.
I am not sure if I has a syntax error or I am trying something not
supported by ansible, or if it's caused by the dictionary not being
evaluated at that point yet:
---
- name: Launch instances based on server list
ec2:
key_name: "{{ server_type[item.key].key_name }}"
group_id: "{{ server_type[item.key].security_group }}"
instance_type: "{{ server_type[item.key].instance_type }}"
image: "{{ server_type[item.key].image }}"
wait: false
region: "{{ server_type[item.key].region }}"
instance_tags:
Type: "{{ item.key }}"
Name: integ-{{ item.value.name }}
exact_count: 1 #dont change!
count_tag:
Name: integ-{{ item.value.name }}
vpc_subnet_id: subnet=blah
assign_public_ip: no
register: ec2
with_dict: "{{ servers }}"
Then I have a dictionary and another list in my /role/vars/main.yml
---
server_type:
integ:
security_groups: ['sg-81398ee4', 'sg-a6398ec3']
image: ami-xxxxxx
instance_type: t2.medium #needs to match the base image size
region: us-west-1
key_name: joeypeters
production:
mysql:
servers:
integ:
name: joey
# name: bob
production:
mysql:
...
I get the following error:
fatal: [localhost] => One or more undefined variables: 'None' has no
attribute 'instance_type'
FATAL: all hosts have already failed -- aborting
I am up for structuring it entirely different if necessary.
Thanks a lot for the help.
