I have a previously working piece of Ansible that I've inherited for a
previous contractor, and I'm getting an error message that doesn't lead me
in the right direction. I have tried searching for a few days now, with no
joy, and my colleagues can't figure it out either.
The Ansible in question is :-
- name: Routes | Set up NAT-protected route table
ec2_vpc_route_table:
vpc_id: "{{ ec2_vpc_net_reg.vpc.id }}"
region: "{{ vpc_region }}"
tags:
Name: "Internal {{ item.subnet_id }}"
subnets:
- "{{ az_to_private_sub[public_subnets_to_az[item.subnet_id]] }}"
- "{{ az_to_private_data_sub[public_subnets_to_az[item.subnet_id]] }}"
routes:
- dest: 0.0.0.0/0
gateway_id: "{{ item.nat_gateway_id }}"
loop: "{{ existing_nat_gateways.result|flatten(levels=1) }}"
#with_items: "{{ existing_nat_gateways.result }}"
register: nat_route_table
retry: 2
delay: 10
And the error message is :-
fatal: [localhost]: FAILED! => {"msg": "The task includes an option with an
undefined variable. The error was: 'dict object' has no attribute
u'subnet-0facefaceface9'\n\n
The error appears to have been in
'/cup/core-kubernetes-linux/ansible/roles/aws_vpc/tasks/routes.yml': line 62,
column 3, but may\n
be elsewhere in the file depending on the exact syntax problem.\n\n
The offending line appears to be:\n\n\n
- name: Routes | Set up NAT-protected route table\n
^ here\n
"}
I have added some carriage returns to make it a bit more readable.
I have tried adding extra debug, for az_to_private_sub and
public_subnet_to_az, and these look OK. I've tried reading the docs
<https://docs.ansible.com/ansible/2.5/user_guide/playbooks_loops.html#using-register-with-a-loop>
Can anyone suggest where I should look next?
Thanks!
