# ChaosIQ extension for the Chaos Toolkit
[](https://travis-ci.com/chaosiq/chaosiq-cloud)
[](https://www.python.org/)
[](http://pythonwheels.com/)
[](https://hub.docker.com/r/chaosiq/chaostoolkit)
This is the ChaosIQ extension package for the [Chaos Toolkit][chaostoolkit].
[chaostoolkit]: https://chaostoolkit.org
## Purpose
The purpose of this package is to communicate with [ChaosIQ][chaosiq] in
order to:
* Publish experiments
* Publish executions of these experiments
* Safely guard the execution via a set of controls
[chaosiq]: https://chaosiq.io
## Install
Install this package as any other Python packages:
```
$ pip install -U chaosiq-cloud
```
## Usage
Once installed, `signin`, `org`, `publish`, `enable`, `disable`, `team` and `verify` will be added
to the `chaos` command.
```console
$ chaos
Usage: chaos [OPTIONS] COMMAND [ARGS]...
Options:
--version Show the version and exit.
--verbose Display debug level traces.
--no-version-check Do not search for an updated version of the
chaostoolkit.
--change-dir TEXT Change directory before running experiment.
--no-log-file Disable logging to file entirely.
--log-file TEXT File path where to write the command's log.
[default: chaostoolkit.log]
--log-format [string|json] Console logging format: string, json.
--settings TEXT Path to the settings file. [default:
~/.chaostoolkit/settings.yaml]
--help Show this message and exit.
Commands:
disable Disable a ChaosIQ feature
discover Discover capabilities and experiments.
enable Enable a ChaosIQ feature
info Display information about the Chaos Toolkit environment.
init Initialize a new experiment from discovered capabilities.
org Set ChaosIQ organisation
publish Publish your experiment's journal to ChaosIQ
run Run the experiment loaded from SOURCE, either a local file or a...
signin Sign-in with your ChaosIQ credentials
team Set ChaosIQ team
validate Validate the experiment at PATH.
verify Run the verification loaded from SOURCE, either a local file or...
```
### Sign-in with ChaosIQ
In order to work, you first need to authenticate with your account on
[ChaosIQ][chaosiq]. First, go there and generate a new token. Copy that
token and paste it when asked from the next command:
```console
$ chaos signin
ChaosIQ url [https://console.chaosiq.io]:
ChaosIQ token:
Here are your known organizations:
1) yourorg
2) TeamA
3) TeamB
Default organization to publish to: 2
Experiments and executions will be published to organization 'TeamA'
ChaosIQ details saved at ~/.chaostoolkit/settings.yaml
```
This is now ready to be used.
### Change ChaosIQ Organization
[ChaosIQ][chaosiq] has support for multiple organizations. You can
specify which of the organizations that you want the ChaosIQ extension to use
by executing the `org` command:
```console
$ chaos org
Here are your known organizations:
1) yourorg
2) TeamA
3) TeamB
Default organization to publish to: 3
Experiments and executions will be published to organization 'TeamB'
ChaosIQ details saved at ~/.chaostoolkit/settings.yaml
```
This is now ready to be used.
### Publish experiments and executions as you run
Once this extension is installed, it starts transmitting the experiments
and their executions to the [ChaosIQ][chaosiq] in your selected organization.
```console
$ chaos run test.json
[2019-09-25 14:42:34 INFO] Validating the experiment's syntax
[2019-09-25 14:42:34 INFO] Experiment looks valid

```
### Publish existing execution
The `publish` command enables you to manually push your experimental
findings, typically recorded in the `journal.json`, to your ChaosIQ
organization.
### Disable safe guards checking
During development time of your experiment, you may wish to disable checking
for safeguards as they can slow your work down. They aren't always relevant
either. To disable the extension from requesting if the execution is allowed
to carry on:
```console
$ chaos disable safeguards
```
Obviously, run the mirroring command to enable them back:
```console
$ chaos enable safeguards
```
### Disable publishing experiments and executions
If you need to disable publishing for a little while:
```console
$ chaos disable publish
```
Note, when you disable publishing, you essentialy disable the entire extension.
Obviously, run the mirroring command to enable publishing again:
```console
$ chaos enable publish
```
### Run a system verification
A system verification is a chaos experiment with an extension block added such as the following:
```javascript
...
"extensions": [
{
"name": "chaosiq",
"verification": {
"id": "SOME_GUID",
"warm-up-duration": 2,
"frequency-of-measurement": 2,
"duration-of-conditions": 10,
"cool-down-duration": 2
}
}
],
...
```
Typically you would create a verification in your [ChaosIQ console][console]. You can execute a verification in exactly the same way as the [`chaos run`][run] default command in the Chaos Toolkit, but instead of `chaos run` you will use `chaos verify`:
[console]: https://console.chaosiq.io
[run]: https://docs.chaostoolkit.org/reference/usage/run/
```console
$ chaos verify my-excellent-verification.json
```
As with Chaos Toolkit experiments, system verifications may be specified in JSON or YAML formats.
## Contribute
Contributors to this project are welcome as this is an open-source effort that
seeks [discussions][join] and continuous improvement.
[join]: https://join.chaostoolkit.org/
From a code perspective, if you wish to contribute, you will need to run a
Python 3.5+ environment. Then, fork this repository and submit a PR. The
project cares for code readability and checks the code style to match best
practices defined in [PEP8][pep8]. Please also make sure you provide tests
whenever you submit a PR so we keep the code reliable.
[pep8]: https://pycodestyle.readthedocs.io/en/latest/
### Develop
If you wish to develop on this project, make sure to install the development
dependencies. But first, [create a virtual environment][venv] and then install
those dependencies.
[venv]: http://chaostoolkit.org/reference/usage/install/#create-a-virtual-environment
```console
$ pip install -r requirements-dev.txt -r requirements.txt
```
Then, point your environment to this directory:
```console
$ pip install -e .
```
Now, you can edit the files and they will be automatically be seen by your
environment, even when running from the `chaos` command locally.
Don't forget to run the linter regularly:
```
$ pylama chaoscloud
```
### Test
To run the tests for the project execute the following:
```
$ pytest
```
### Release
In order to release this package, you must first bump its version in
`chaoscloud/__init__.py` as well as the CHANGELOG. Commit and push these
changes. Then run the followings:
```
$ git tag VERSION
$ git push origin VERSION
```
where `VERSION` is the semantic version you set in `chaoscloud/__init__.py`.
Once the tag was built, it should have released the package on Pypi.
