Hi matt,
Thanks for your reply !
That's already a good example, But I need somehow also to retrieve the
index which is the chain number.
Let's simplify and say we only have one type of deployment (routed or
bridged):
chains_config:
1:
foo: bar
configs:
- type: bridged
version: 0.2
2:
foo: baz
configs:
- type: routed
version: 1.0
To briefly explain the context we have two type of network deployment
(routed or bridged). Each of these network deployment have their own
set of network interfaces / VLANs. The VLAN used is guess from the chain
number and type of deployment. And the type of deployment is specified in
the chains_config dict.
On top of this network architecture a docker container is applied for
network type / VLANs.
A dumb naive approach would be:
- name: Creating docker network for the chain
include_role:
name: docker_chain_network
vars:
docker_network:
name: macvlan{{item.key}}0{{ '6' if item.value.type == 'routed' else
'5' }}
driver: macvlan
driver_options:
parent: "{{ 'eno52' if routed else 'eno51' }}".{{item.key}}0{{ '6'
if item.value.type == routed else '5' }}"
with: ? map/select ?
item.key ==> Would be each index of chains[] list (iteratively).
item.value.type ==> Would be type of deployment based the index above; like
in python: chains_config[item.key]['configs']['type']
docker_chain_network is just a role applying docker_network module with the
vars passed to the role.
This is rather complex stuff. Thanks for taking your time and for your
answers.
Best regards,
Lionel.
