# [Chaos Toolkit Extension for z/OS]()
[](https://github.com/Tam-Lin/chaostoolkit-zos/actions/workflows/build-and-test.yaml)
[](https://www.python.org/)
This project is a collection of [actions][] and [probes][] to allow the [Chaos Toolkit][chaostoolkit] to interact
with [z/OS]. This is a very early release, put out for people to experiment with
and critique. It is usable, but very limited in scope. I eventually plan to incorporate tests for program products
(db2, CICS, IMS, etc), but need feedback to understand what to prioritize.
I will also be adding some overview videos to my [youtube channel][].

## Install
This package requires Python 3.7+
This package needs to be installed in a Python environment where the [chaostoolkit][] is already installed.
``pip install -U chaostoolkit-zos``
## Usage
To use the actions in the package, add the following to your experiment file:
```json
{
"type": "action",
"name": "configure_all_ziips_offline",
"provider": {
"type": "python",
"module": "chaoszos.zos.actions",
"func": "configure_processors",
"secrets": [
"zos_console"
],
"arguments": {
"location": "S5C",
"processor_type_to_change": "ziip",
"status_to_change_to": "offline"
}
}
}
```
## Configuration
### Access Methods
There are a number of different ways to interact with z/OS, and a number of interfaces for each method of interaction.
For example, to issue a z/OS console command, you can connect to an HMC/SE, use the ZOAU interfaces, Ansible, the z/OSMF
REST APIs, or Zowe. Similarly, for submitting jobs, you can use FTP, or zoau, or Zowe, or z/OSMF. And different
installations have different legal and security requirements that will dictate which methods could be used. As such, the
toolkit plans to allow multiple ways of doing any of these activities, without needing to change your high level
experiment. The contents of your secrets will dictate which access method is used for a given experiment.
Right now, two methods are supported for issuing commands: using an HMC connection, or zoau after connecting via ssh.
### Credentials
In order to issue commands, you need to give the extension a couple of pieces of information: how to connect to z/OS or
the subsystem, and credentials to connect. In order to make this as transparent as possible, you can specify this
information in your secrets section, and not have to change the experiment itself at all. For example, to use the z/OS
hmc to issue commands in the above sample, you could specify
```json
{
"secrets": {
"zos_console": {
"S5C": {
"method": "hmc",
"hostname": "ioshmc3.pok.stglabs.ibm.com",
"userid": {
"type": "env",
"key": "IOSHMC3_USERID"
},
"password": {
"type": "env",
"key": "IOSHMC3_PASSWORD"
}
}
}
}
}
```
Or, to use the ssh interface, provided by ZOAU, you could specify
```json
{
"secrets": {
"zos_console": {
"S5C": {
"method": "ssh",
"hostname": "pksts5c.pok.stglabs.ibm.com",
"userid": {
"type": "env",
"key": "S5C_USERID"
},
"password": {
"type": "env",
"key": "S5C_PASSWORD"
}
}
}
}
}
```
In both cases, instead of hard-coding the userid and password, you can specify them via environmental variables. This
is all handled by the Chaos Toolkit, so any supported method for passing in secrets will work.
If you are using certificates signed by an internal/private certificate authority, you may have problems connecting
to your HMC. If this is the case, you can work around the problem by setting environmental variable REQUESTS_CA_BUNDLE
to the location of the signing certificate. Note that this will then cause problems in contacting pypi.
## Contribute
If you wish to contribute more functions to this package, you are welcome to do so. First, fork this project,
make your changes following the usual [PEP 8][pep8] code style, add tests and submit a PR for review. Or, if you'd like
to be able to do something with the Chaos Toolkit, but don't know how to do it via code, feel free to submit a problem
report, and I'll see what I can figure out. I'm hoping to add support for z/OS subsystems (CICS, Db2, IMS, etc), but my
exptertise is in z/OS, so I need to understand what sorts of things you'd like to be able to do.

The Chaos Toolkit projects require all contributors must sign a
[Developer Certificate of Origin][dco] on each commit they would like to merge into the master branch of the repository.
Please, make sure you can abide by the rules of the DCO before submitting a PR.

### 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
$ python setup.py develop
```
Now, you can edit the files and they will be automatically be seen by your environment, even when running from
the `chaos` command locally.
### Test
To run the tests for the project execute the following:
```
$ pytest
```
