# Contributor Guideline
|
||||
|
||||
This document provides an overview of how you can participate in improving this project or extending it. We are
|
||||
grateful for all your help: bug reports and fixes, code contributions, documentation or ideas. Feel free to join, we
|
||||
appreciate your support!!
|
||||
|
||||
## Communication
|
||||
|
||||
### GitHub repositories
|
||||
|
||||
Much of the issues, goals and ideas are tracked in the respective projects in GitHub. Please use this channel to report
|
||||
bugs, ask questions, and request new features .
|
||||
|
||||
## git and GitHub
|
||||
|
||||
In order to contribute code please:
|
||||
|
||||
1. Fork the project on GitHub
|
||||
2. Clone the project
|
||||
3. Add changes (and tests)
|
||||
4. Commit and push
|
||||
5. Create a merge-request
|
||||
|
||||
To have your code merged, see the expectations listed below.
|
||||
|
||||
You can find a well-written guide [here](https://help.github.com/articles/fork-a-repo).
|
||||
|
||||
Please follow common commit best-practices. Be explicit, have a short summary, a well-written description and
|
||||
references. This is especially important for the merge-request.
|
||||
|
||||
Some great guidelines can be found [here](https://wiki.openstack.org/wiki/GitCommitMessages) and
|
||||
[here](http://robots.thoughtbot.com/5-useful-tips-for-a-better-commit-message).
|
||||
|
||||
## Releases
|
||||
|
||||
We try to stick to semantic versioning and our releases are automated. Release is created by assigning a keyword (in a
|
||||
way similar to circle ci keyword [`[ci skip]`](https://docs.travis-ci.com/user/customizing-the-build#Skipping-a-build))
|
||||
to a commit with merge request. Available keywords are (square brackets are important!):
|
||||
|
||||
* `[patch]`, `[fix]`, `[bugfix]` - for PATCH version release
|
||||
* `[minor]`, `[feature]`, `[feat]` - for MINOR version release
|
||||
* `[major]`, `[breaking change]` - for MAJOR version release
|
||||
|
||||
## Changelog
|
||||
|
||||
Changelog is generated automatically during release process and all information is taken from github issues, PRs and
|
||||
labels.
|
||||
|
||||
## Expectations
|
||||
|
||||
### Keep it simple
|
||||
|
||||
We try to provide production ready ansible roles which should be as much zero-conf as possible but this doesn't mean to
|
||||
overcomplicate things. Just follow [KISS](https://en.wikipedia.org/wiki/KISS_principle).
|
||||
|
||||
### Be explicit
|
||||
|
||||
* Please avoid using nonsensical property and variable names.
|
||||
* Use self-describing attribute names for user configuration.
|
||||
* In case of failures, communicate what happened and why a failure occurs to the user. Make it easy to track the code
|
||||
or action that produced the error. Try to catch and handle errors if possible to provide improved failure messages.
|
||||
|
||||
|
||||
### Add tests
|
||||
|
||||
We are striving to use at least two test scenarios located in [/molecule](molecule) directory. First one
|
||||
([default](molecule/default)) is testing default configuration without any additional variables, second one
|
||||
([alternative](molecule/alternative)) is testing what happens when many variables from
|
||||
[/defaults/main.yml](defaults/main.yml) are changed. When adding new functionalities please add tests to proper
|
||||
scenarios. Tests are written in testinfra framework and are located in `/tests` subdirectory of scenario directory
|
||||
(for example default tests are in [/molecule/default/tests](molecule/default/tests)).
|
||||
More information about:
|
||||
- [testinfra](http://testinfra.readthedocs.io/en/latest/index.html)
|
||||
- [molecule](https://molecule.readthedocs.io/en/latest/index.html)
|
||||
|
||||
### Follow best practices
|
||||
|
||||
Please follow [ansible best practices](http://docs.ansible.com/ansible/latest/playbooks_best_practices.html) and
|
||||
especially provide meaningful names to tasks and even comments where needed.
|
||||
|
||||
Our test framework automatically lints code with [`yamllint`](https://github.com/adrienverge/yamllint),
|
||||
[`ansible-lint`](https://github.com/willthames/ansible-lint), and [`flake8`](https://gitlab.com/pycqa/flake8) programs
|
||||
so be sure to follow their rules.
|
||||
|
||||
Remember: Code is generally read much more often than written.
|
||||
|
||||
### Use Markdown
|
||||
|
||||
Wherever possible, please refrain from any other formats and stick to simple markdown.
|
||||
|
||||
## Requirements regarding roles design
|
||||
|
||||
We are trying to create the best and most secure installation method for non-containerized prometheus stack components.
|
||||
To accomplish this all roles need to support:
|
||||
|
||||
- current and at least one previous ansible version
|
||||
- systemd as the only available process manager
|
||||
- at least latest debian and CentOS distributions

# Collections Plugins Directory
|
||||
|
||||
This directory can be used to ship various plugins inside an Ansible collection. Each plugin is placed in a folder that
|
||||
is named after the type of plugin it is in. It can also include the `module_utils` and `modules` directory that
|
||||
would contain module utils and modules respectively.
|
||||
|
||||
Here is an example directory of the majority of plugins currently supported by Ansible:
|
||||
|
||||
```
|
||||
└── plugins
|
||||
├── action
|
||||
├── become
|
||||
├── cache
|
||||
├── callback
|
||||
├── cliconf
|
||||

# Ansible Role: alertmanager
|
||||
|
||||
## Description
|
||||
|
||||
Deploy and manage Prometheus [alertmanager](https://github.com/prometheus/alertmanager) service using ansible.
|
||||
|
||||
## Requirements
|
||||
|
||||
- Ansible >= 2.7 (It might work on previous versions, but we cannot guarantee it)
|
||||
|
||||
It would be nice to have prometheus installed somewhere
|
||||
|

## Example
|
||||
|
||||
### Playbook
|
||||
|
||||
```yaml
|
||||
---
|
||||
hosts: all
|
||||
roles:
|
||||
- ansible-alertmanager
|
||||
vars:
|
||||
alertmanager_version: latest
|
||||
alertmanager_slack_api_url: "http://example.com"
|
||||
alertmanager_receivers:
|
||||
- name: slack
|
||||
slack_configs:
|
||||
- send_resolved: true
|
||||
channel: '#alerts'
|
||||
alertmanager_route:
|
||||
group_by: ['alertname', 'cluster', 'service']
|
||||
group_wait: 30s
|
||||
group_interval: 5m
|
||||
repeat_interval: 3h
|
||||
receiver: slack
|
||||
```
|
||||
|
||||
### Demo site
|
||||
|
||||
We provide demo site for full monitoring solution based on prometheus and grafana. Repository with code and links to running instances is [available on github](https://github.com/prometheus/demo-site) and 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 to 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 a quite large test matrix which can take more time than local testing, so please be patient.

# Ansible Role: Blackbox Exporter
|
||||
|
||||
# Description
|
||||
|
||||
Deploy and manage [blackbox exporter](https://github.com/prometheus/blackbox_exporter) which allows blackbox probing of endpoints over HTTP, HTTPS, DNS, TCP and ICMP.
|
||||
|
||||
## Requirements
|
||||
|
||||
- Ansible >= 2.7 (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 table below.
|
||||
|
||||
| Name | Default Value | Description |
|
||||
| -------------- | ------------- | -----------------------------------|
|
||||
| `blackbox_exporter_version` | 0.18.0 | Blackbox exporter package version |
|
||||
| `blackbox_exporter_web_listen_address` | 0.0.0.0:9115 | Address on which blackbox exporter will be listening |
|
||||
| `blackbox_exporter_cli_flags` | {} | Additional configuration flags passed to blackbox exporter binary at startup |
|
||||
| `blackbox_exporter_configuration_modules` | http_2xx: { prober: http, timeout: 5s, http: '' } | |
|
||||
|
||||
## Example
|
||||
|
||||
### Playbook
|
||||
|
||||
```yaml
|
||||
- hosts: all
|
||||
become: true
|
||||
roles:
|
||||
- cloudalchemy.blackbox-exporter
|
||||
```
|
||||
|
||||
### Demo site
|
||||
|
||||
We provide demo site for full monitoring solution based on prometheus and grafana. Repository with code and links to running instances is [available on github](https://github.com/prometheus/demo-site) and 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 to for your system. Running your tests is as simple as executing `molecule test`.
|
||||
|
||||
## Continuous Intergation
|
||||
|
||||
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.

# Ansible Role: node exporter
|
||||
|
||||
## Warning
|
||||
|
||||
Due to limitations of galaxy.ansible.com we had to move the role to https://galaxy.ansible.com/cloudalchemy/node_exporter and use `_` instead of `-` in role name. This is a breaking change and unfortunately, it affects all versions of node_exporter role as ansible galaxy doesn't offer any form of redirection. We are sorry for the inconvenience.
|
||||
|
||||
## Description
|
||||
|
||||
Deploy prometheus [node exporter](https://github.com/prometheus/node_exporter) using ansible.
|
||||
|
||||
## Requirements
|
||||
|
||||
- Ansible >= 2.7 (It might work on previous versions, but we cannot guarantee it)
|
||||
- gnu-tar on Mac deployer host (`brew install gnu-tar`)
|
||||
- Passlib is required when using the basic authentication feature (`pip install passlib[bcrypt]`)
|
||||
|
||||
## Role Variables
|
||||
|
||||
All variables which can be overridden are stored in [defaults/main.yml](defaults/main.yml) and are listed in the table below.
|
||||
|
||||
| Name | Default Value | Description |
|
||||
| -------------- | ------------- | -----------------------------------|
|
||||
| `node_exporter_version` | 1.1.2 | Node exporter package version. Also accepts latest as parameter. |
|
||||
| `node_exporter_binary_local_dir` | "" | Enables the use of local packages instead of those distributed on github. The parameter may be set to a directory where the `node_exporter` binary is stored on the host where ansible is run. This overrides the `node_exporter_version` parameter |
|
||||
| `node_exporter_web_listen_address` | "0.0.0.0:9100" | Address on which node exporter will listen |
|
||||
| `node_exporter_web_telemetry_path` | "/metrics" | Path under which to expose metrics |
|
||||
| `node_exporter_enabled_collectors` | ```["systemd",{textfile: {directory: "{{node_exporter_textfile_dir}}"}}]``` | List of dicts defining additionally enabled collectors and their configuration. It adds collectors to [those enabled by default](https://github.com/prometheus/node_exporter#enabled-by-default). |
|
||||
| `node_exporter_disabled_collectors` | [] | List of disabled collectors. By default node_exporter disables collectors listed [here](https://github.com/prometheus/node_exporter#disabled-by-default). |
|
||||
| `node_exporter_textfile_dir` | "/var/lib/node_exporter" | Directory used by the [Textfile Collector](https://github.com/prometheus/node_exporter#textfile-collector). To get permissions to write metrics in this directory, users must be in `node-exp` system group. __Note__: More information in TROUBLESHOOTING.md guide.
|
||||
| `node_exporter_tls_server_config` | {} | Configuration for TLS authentication. Keys and values are the same as in [node_exporter docs](https://github.com/prometheus/node_exporter/blob/master/https/README.md#sample-config). |
|
||||
| `node_exporter_http_server_config` | {} | Config for HTTP/2 support. Keys and values are the same as in [node_exporter docs](https://github.com/prometheus/node_exporter/blob/master/https/README.md#sample-config). |
|
||||
| `node_exporter_basic_auth_users` | {} | Dictionary of users and password for basic authentication. Passwords are automatically hashed with bcrypt. |
|
||||
|
||||
## Example
|
||||
|
||||
### Playbook
|
||||
|
||||
Use it in a playbook as follows:
|
||||
```yaml
|
||||
- hosts: all
|
||||
roles:
|
||||
- cloudalchemy.node_exporter
|
||||
```
|
||||
|
||||
### TLS config
|
||||
|
||||
Before running node_exporter role, the user needs to provision their own certificate and key.
|
||||
```yaml
|
||||
- hosts: all
|
||||
pre_tasks:
|
||||
- name: Create node_exporter cert dir
|
||||
file:
|
||||
path: "/etc/node_exporter"
|
||||
state: directory
|
||||
owner: root
|
||||
group: root
|
||||
|
||||
- name: Create cert and key
|
||||
openssl_certificate:
|
||||
path: /etc/node_exporter/tls.cert
|
||||
csr_path: /etc/node_exporter/tls.csr
|
||||
privatekey_path: /etc/node_exporter/tls.key
|
||||
provider: selfsigned
|
||||
roles:
|
||||
- cloudalchemy.node_exporter
|
||||
vars:
|
||||
node_exporter_tls_server_config:
|
||||
cert_file: /etc/node_exporter/tls.cert
|
||||
key_file: /etc/node_exporter/tls.key
|
||||
node_exporter_basic_auth_users:
|
||||
randomuser: examplepassword
|
||||
```
|
||||
|
||||
|
||||
### 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.

# Troubleshooting
|
||||
|
||||
## Bad requests (HTTP 400)
|
||||
|
||||
This role downloads checksums from the Github project to verify the integrity of artifacts installed on your servers. When downloading the checksums, a "bad request" error might occur.
|
||||
|
||||
This happens in environments which (knowningly or unknowling) use the [netrc mechanism](https://www.gnu.org/software/inetutils/manual/html_node/The-_002enetrc-file.html) to auto-login into servers.
|
||||
|
||||
Unless netrc is needed by your playbook and ansible roles, please unset the var like so:
|
||||
|
||||
```
|
||||
$ NETRC= ansible-playbook ...
|
||||
```
|
||||
|
||||
Or:
|
||||
|
||||
```
|
||||
$ export NETRC=
|
||||
$ ansible-playbook ...
|
||||
```
|
||||
|
||||
## node_exporter doesn't report data from textfile collector
|
||||
|
||||
There are 3 potential issues why node_exporter doesn't pick up data:
|
||||
|
||||
1. Duplicated metrics across multiple files.
|
||||
2. File is not readable by node_exporter process.
|
||||
3. Textfile collector is not enabled.
|
||||
|
||||
Solving first possibility is out of scope of the role as data is created somewhere else. When creating that data ensure
|
||||
files are readable by `node-exp` user. To get access to the directory with files your process needs to be in `node-exp`
|
||||
group.
|
||||
|
||||
Lastly ansible role misconfiguration can also lead to data not being picked up. Check if `node_exporter` textfile
|
||||
collector is enabled in `node_exporter_enabled_collectors` as follows:
|
||||
|
||||
```yaml
|
||||
node_exporter_enabled_collectors:
|
||||
- textfile:
|
||||
directory: "{{ node_exporter_textfile_dir }}"
|
||||
```
|
||||
|
||||
__note___: `node_exporter_textfile_dir` variable is only responsible for creating a directory not enabling a collector.

# Ansible Role: prometheus
|
||||
|
||||
## Description
|
||||
|
||||
Deploy [Prometheus](https://github.com/prometheus/prometheus) monitoring system using ansible.
|
||||
|
||||
### Upgradability notice
|
||||
|
||||
When upgrading from <= 2.4.0 version of this role to >= 2.4.1 please turn off your prometheus instance. More in [2.4.1 release notes](https://github.com/cloudalchemy/ansible-prometheus/releases/tag/2.4.1)
|
||||
|
||||
## Requirements
|
||||
|
||||
- Ansible >= 2.7 (It might work on previous versions, but we cannot guarantee it)
|
||||
- jmespath on deployer machine. If you are using Ansible from a Python virtualenv, install *jmespath* to the same virtualenv via pip.
|
||||
- gnu-tar on Mac deployer host (`brew install gnu-tar`)
|
||||
|
||||
## Role Variables

|
||||
|
||||
|
||||
### Relation between `prometheus_scrape_configs` and `prometheus_targets`
|
||||
|
||||
#### Short version
|
||||
|
||||
`prometheus_targets` is just a map used to create multiple files located in "{{ prometheus_config_dir }}/file_sd" directory. Where file names are composed from top-level keys in that map with `.yml` suffix. Those files store [file_sd scrape targets data](https://prometheus.io/docs/prometheus/latest/configuration/configuration/#file_sd_config) and they need to be read in `prometheus_scrape_configs`.
|
||||
|
||||
#### Long version
|
||||
|
||||
A part of *prometheus.yml* configuration file which describes what is scraped by prometheus is stored in `prometheus_scrape_configs`. For this variable same configuration options as described in [prometheus docs](https://prometheus.io/docs/prometheus/latest/configuration/configuration/#<scrape_config>) are used.
|
||||
|
||||
Meanwhile `prometheus_targets` is our way of adopting [prometheus scrape type `file_sd`](https://prometheus.io/docs/prometheus/latest/configuration/configuration/#<file_sd_config>). It defines a map of files with their content. A top-level keys are base names of files which need to have their own scrape job in `prometheus_scrape_configs` and values are a content of those files.
|
||||
|
||||
All this mean that you CAN use custom `prometheus_scrape_configs` with `prometheus_targets` set to `{}`. However when you set anything in `prometheus_targets` it needs to be mapped to `prometheus_scrape_configs`. If it isn't you'll get an error in preflight checks.
|
||||
|
||||
#### Example
|
||||
|
||||
Lets look at our default configuration, which shows all features. By default we have this `prometheus_targets`:
|
||||
```
|
||||
prometheus_targets:
|
||||
node: # This is a base file name. File is located in "{{ prometheus_config_dir }}/file_sd/<<BASENAME>>.yml"
|
||||
- targets: #
|
||||
- localhost:9100 # All this is a targets section in file_sd format
|
||||
labels: #
|
||||
env: test #
|
||||
```
|
||||
Such config will result in creating one file named `node.yml` in `{{ prometheus_config_dir }}/file_sd` directory.
|
||||
|
||||
Next this file needs to be loaded into scrape config. Here is modified version of our default `prometheus_scrape_configs`:
|
||||
```
|
||||
prometheus_scrape_configs:
|
||||
- job_name: "prometheus" # Custom scrape job, here using `static_config`
|
||||
metrics_path: "/metrics"
|
||||
static_configs:
|
||||
- targets:
|
||||
- "localhost:9090"
|
||||
- job_name: "example-node-file-servicediscovery"
|
||||
file_sd_configs:
|
||||
- files:
|
||||
- "{{ prometheus_config_dir }}/file_sd/node.yml" # This line loads file created from `prometheus_targets`
|
||||
```
|
||||
|
||||
## Example
|
||||
|
||||
### Playbook
|
||||
|
||||
```yaml
|
||||
---
|
||||
- hosts: all
|
||||
roles:
|
||||
- cloudalchemy.prometheus
|
||||
vars:
|
||||
prometheus_targets:
|
||||
node:
|
||||
- targets:
|
||||
- localhost:9100
|
||||
- demo.cloudalchemy.org:9100
|
||||
labels:
|
||||
env: demosite
|
||||
```
|
||||
|
||||
### Demo site
|
||||
|
||||
Prometheus organization provide a demo site for full monitoring solution based on prometheus and grafana. Repository with code and links to running instances is [available on github](https://github.com/prometheus/demo-site).
|
||||
|
||||
### Defining alerting rules files
|
||||
|
||||
Alerting rules are defined in `prometheus_alert_rules` variable. Format is almost identical to one defined in[ Prometheus 2.0 documentation](https://prometheus.io/docs/prometheus/latest/configuration/template_examples/).
|
||||
Due to similarities in templating engines, every templates should be wrapped in `{% raw %}` and `{% endraw %}` statements. Example is provided in [defaults/main.yml](defaults/main.yml) file.
|
||||
|
||||
## Local Testing

||||
|
||||
The preferred way of locally testing the role is to use Docker and [molecule](https://github.com/metacloud/molecule) (v2.x). You will have to install Docker on your system. See "Get started" for a Docker package suitable to for your system.
|
||||
We are using tox to simplify process of testing on multiple ansible versions. To install tox execute:
|
||||
```sh
|
||||
pip3 install tox
|
||||
```
|
||||
To run tests on all ansible versions (WARNING: this can take some time)
|
||||
```sh
|
||||
tox
|
||||
```
|
||||
To run a custom molecule command on custom environment with only default test scenario:
|
||||
```sh
|
||||
tox -e py35-ansible28 -- molecule test -s default
|
||||
```
|
||||
For more information about molecule go to their [docs](http://molecule.readthedocs.io/en/latest/).
|
||||
|
||||
If you would like to run tests on remote docker host just specify `DOCKER_HOST` variable before running tox tests.
|
||||
|
||||
## CircleCI
|
||||
|
||||
Combining molecule and CircleCI 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 will take more time than local testing, so please be patient.
