Multi-dimensional group_vars ?

[Renaud Guerin]

Hi,

I have a variable "elasticsearch_heap_size" that can take 4 different values depending on 2 dimensions:

- the host being an Elasticsearch master or data node

- whether it's in production or development.

At the moment, I have 2 inventory files "production" and "development", and I set the variable directly within each using [elasticsearch-master:vars] and [elasticsearch-data:vars]

However, I know that setting variables inside static inventory files is discouraged in favor of using group_vars directories.

How would I go about doing this when the variable depends BOTH on production/development group membership ?

Thanks

I like to set values like that in group_vars/all/<something_descriptive>.yml

e.g.
# file: group_vars/definitions.yml

---
elastic_search_values:
  production: 5
  development: 3

# file: group_vars/elasticsearch-master.yml

elastic_search: production

# file: group_vars/elasticsearch-data.yml

elastic_search: development

Then reference it like:

{{ elastic_search_vars[elastic_search] }}
