SousChef: Multi-Platform to Ansible Migration + Ansible Upgrade Planning

Transform Chef, SaltStack, Puppet, PowerShell, and Bash automation to Ansible, and plan Ansible version upgrades. Works with any AI assistant via MCP (Model Context Protocol)—Claude, GPT-4, GitHub Copilot, Red Hat AI, local models, and more.

Warning I did not hand craft 100k lines of code in two days while doing my actual day job (which, for the record, isn’t this). A lot of this is AI generated. Architected, hand edited, and personally sworn at yes, but the heavy hand of AI is all over this repo.

I’ve pushed it to include a lot of tests, and I run it through its paces before pushing, but some things may break, or may have always been broken. If you find something, raise it and I’ll fix it.

A fair bit of this relies on mocked Chef/AWX/AAP APIs because shockingly I don’t have a fleet of enterprise grade installs with enterprise grade data sitting around to test against. Buyer beware (doubly so, since you didn’t actually buy anything).

What It Does

Chef-to-Ansible Migration — Convert cookbooks, recipes, custom resources, data bags, and Habitat plans to Ansible playbooks, roles, and containers. Supports infrastructure, applications, and day-2 operations.

SaltStack-to-Ansible Migration — Convert Salt states, pillars, and top.sls targeting to Ansible roles, variable files, Ansible Vault, and INI inventory. Assess complexity, generate phased migration plans, and produce executive reports.

Puppet to Ansible Migration — Convert Puppet manifests and module directories to Ansible playbooks using idiomatic ansible.builtin modules. Recognises 14 Puppet resource types; maps 10 to Ansible modules with AI-assisted conversion for complex constructs.

PowerShell to Ansible Migration — Convert Windows PowerShell provisioning scripts to idiomatic ansible.windows playbooks, roles, WinRM inventories, and AWX/AAP job templates.

Bash Script Migration — Convert provisioning Bash scripts to Ansible playbooks and roles with quality scoring, sensitive data detection, and AAP readiness hints.

Ansible Upgrade Planning — Assess compatibility, plan version upgrades, validate collections, identify breaking changes, and generate testing strategies.

Common Use Cases

Chef Migration:

• Convert cookbooks to Ansible playbooks and roles

• Migrate Chef Habitat apps to Docker containers

• Transform data bags to Ansible Vault

• Generate AWX/AAP job templates and workflows

• Convert InSpec tests to Ansible validation tasks

• Fetch cookbooks from Chef Server with run_list or policy selection

SaltStack Migration:

• Parse SLS state files and extract states, pillars, and grain references

• Convert Salt states to Ansible playbooks and role task files

• Migrate pillar data to Ansible group_vars/ and Ansible Vault

• Generate Ansible inventory from top.sls targeting rules

• Batch-convert a full Salt state tree to an Ansible roles structure

• Assess migration complexity and generate phased migration plans

Puppet Migration:

• Convert Puppet manifests (.pp) and module directories to Ansible playbooks

• Recognise 14 Puppet resource types; map 10 to idiomatic ansible.builtin modules (package, service, file, user, group, exec, cron, host, mount, ssh_authorized_key)

• Warn about unsupported constructs (Hiera lookups, exported resources, create_resources) with manual-review guidance

• AI-assisted conversion for complex Puppet DSL that cannot be mapped automatically

• Convert individual Puppet resource declarations to standalone Ansible tasks

PowerShell Migration:

• Convert Windows PowerShell provisioning scripts to idiomatic Ansible playbooks

• Generate full Ansible roles with WinRM inventory and group_vars

• Map 28+ PowerShell patterns to ansible.windows.*, community.windows.*, chocolatey.chocolatey.*

• Generate AWX/AAP Windows job templates with WinRM credentials

• Analyse migration fidelity (0–100 %) with actionable recommendations

• Create complete requirements.yml for required Windows collections

Bash Script Migration:

• Convert provisioning Bash scripts to idiomatic Ansible playbooks

• Generate full Ansible roles from Bash scripts (tasks, handlers, defaults, meta)

• Detect and flag hardcoded secrets with ansible-vault guidance

• Identify CM escape calls (Salt, Puppet, Chef) embedded in Bash

• Get AAP-ready job template hints with Execution Environment recommendations

• Score migration quality (A–F) with ranked improvement suggestions

Ansible Upgrades:

• Assess Python and Ansible version compatibility

• Plan upgrades with breaking change analysis

• Validate collection compatibility

• Generate testing strategies

• Track end-of-life dates

Both Infrastructure & Applications:

• Infrastructure provisioning and configuration

• Application deployment automation

• Day-2 operations (backups, scaling, updates)

• CI/CD pipeline migration

• Multi-cloud automation
