# Shell to Python Continuous Deployment
Get a common set of Python based CI / CD commands\
from various contexts of CA, DNS, CI and OS / OCI.
---
## Why
Project workflows can occur in:
* an online or offline context, dealing with custom CA & DNS servers
* various Continuous Integration platforms, with different workflow syntaxes
* specific Operating Systems, having different commands and package names
* specific containers for JavaScript based actions (ForgeJo, Gitea, GitHub)
What if there was a unified way to do so?
---
## How
Picture it…
### Group environment variables
* numbered
* Certificate Authority armored certificates
* Domain Name System servers IP addresses
* ref names for deployment contexts of feature, staging & release
* alternate locations of
* Operating Systems & Software packages
* Git repositories of
* this project
* its parent framework
* projects not available in some distributions
* shunit2
* SSH key & hosts for deployments
* a standalone POSIX shell script payload
### Workflow files
* calling the POSIX shell script payload as their very first step
* using a unified YAML syntax made of actions implemented in Python
### Integration & Deployment
#### Shell
* [X] setting up the chosen Operating System container
* [X] Domain Name System resolving
* [X] package manager configuration & repositories
* [X] Certificate Authorities trusting
* [X] Operating System updating
* [X] installing Git to clone
* [X] this project
* [X] its parent framework
* [X] installing both Python
* [X] system environment
* [X] virtual environment
* [X] generating a Python module to switch context
#### Python
* [X] setting up an OpenSSH client
* [X] known hosts
* [ ] private key
* [ ] and finally parsing commands from
* [X] system
* [ ] workflow
* [ ] to run available actions
* [ ] check project
* [ ] build project
* [X] browse workspace
* [ ] synchronize

## What

* whether the network infrastructure is
* [X] online
