Deploy cortex using ansible.

• Ansible >= 2.7 (It might work on previous versions, but we cannot guarantee it)

All variables which can be overridden are stored in defaults/main.yml file as well as in table below.

Use it in a playbook as follows:

- hosts: all
  roles:
    - cloudalchemy.cortex

You can run the different Cortex modules as separate services by setting cortex_services as a module:config map and cortex_all_in_one to false.

- hosts: all
  roles:
    - cloudalchemy.cortex
  vars:
    cortex_all_in_one: false
    cortex_services:
      ingester:
        server:
            http_listen_port: 9009
        ingester:
            lifecycler:
              join_after: 0
              min_ready_duration: 0s
              final_sleep: 0s
              num_tokens: 512

              ring:
                kvstore:
                  store: inmemory
                  replication_factor: 1
    cortex_env_variables:
      ingester:
        JAEGER_AGENT_HOST: localhost
        JAEGER_SAMPLER_PARAM: 0
        JAEGER_SAMPLER_TYPE: const

The preferred way of locally testing the role is to use Docker and molecule (v3.x). You will have to install Docker on your system. See "Get started" for a Docker package suitable to for your system. Running your tests is as simple as executing molecule test.

Combining molecule and circle CI allows us to test how new PRs will behave when used with multiple ansible versions and multiple operating systems. This also allows use to create test scenarios for different role configurations. As a result we have a quite large test matrix which can take more time than local testing, so please be patient.
