+# Ansible Role: influxdb exporter
+
+## Description
+
+Deploy prometheus [influxdb exporter](https://github.com/prometheus/influxdb_exporter) using ansible.
+
+## Requirements
+
+- Ansible >= 2.9 (It might work on previous versions, but we cannot guarantee it)
+- gnu-tar on Mac deployer host (`brew install gnu-tar`)
+
+## Role Variables
+
+All variables which can be overridden are stored in [defaults/main.yml](defaults/main.yml) file as well as in [meta/argument_specs.yml](meta/argument_specs.yml).
+Please refer to the [collection docs](https://prometheus-community.github.io/ansible/branch/main/influxdb_exporter_role.html) for description and default values of the variables.
+
+## Example
+
+### Playbook
+
+Use it in a playbook as follows:
+
+```yaml
+- hosts: all
+  roles:
+    - prometheus.prometheus.influxdb_exporter
+```
+
+### Demo site
+
+We provide an example site that demonstrates a full monitoring solution based on prometheus and grafana.
+The repository with code and links to running instances is [available on github](https://github.com/prometheus/demo-site) and the site is hosted on [DigitalOcean](https://digitalocean.com).
+
+## Local Testing
+
+The preferred way of locally testing the role is to use Docker and [molecule](https://github.com/ansible-community/molecule) (v3.x).
+You will have to install Docker on your system. See "Get started" for a Docker package suitable for your system. Running your tests is as simple as executing `molecule test`.
+
+## Continuous Integration
+
+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 quite a large test matrix which can take more time than local testing, so please be patient.
