Hi,
I'm writing a cookbook to deploy a service, of which multiple instances can
run at the same time on the same host.
Each instance requires 3 config files: config_X.yml, config_X.env,
log_X.conf, where X=instance number.
I have a template for each config file.
I want the cookbook to set things up for 3 instances.
Having read the doc, it seems I could go in this direction:
Define the 3 instances in an array variable called instances (each having
an index member), and loop over it:
- include: lib/copy_config_files.yml
with_nested:
- "{{ instances }} "
- [ "config_X.yml", "config_X.env", "log_X.conf" ]
and in the lib/copy_config_files.yml, loop over the config files:
- name: copy mode 1 config
template: ....
when: mode == 1
- name: copy mode 2 config
template: ....
when: mode == 2
- name: "Copy configs"
template: src=templates/{{item[1]}} dest=/etc/{{item[1] |
regex_replace('X',{{item[0].index}})}} owner=root group=root mode=0744
First question: is this the right approach?
Second: what's the best solution to the conditional template for mode1 and
mode2 configs? With this cookbook it is unnecessarily generated multiple
times. Is the solution to extract these to a seperate fil included one
level higher?
thanks in advance for any tips!
