Prototype Gitops Rake Task Workflow

[samsimpson1]

User Need

As a GOV.UK developer
I want a user-friendly approach to running Rake tasks
so that I can continue doing so without pod shell access

---

Context

(Add any extra context, links, diagrams, stakeholder interviews, etc.)

Shell access alternatives document

https://github.com/alphagov/govuk-platform-internal/issues/99

What’s Needed

List anything the solution must do or be (behaviour, performance, security, UX, etc.).

• Prototype a Gitops workflow for executing rake tasks using a job runner such as Argo Workflows or Concourse
• Build an abstraction layer on top of the chosen tool to make creating new tasks simpler

---

Acceptance Criteria

Clear, measurable conditions to verify the story is complete and valuable.

• A proof-of-concept for a Rake task execution workflow has been created
• Approval is required for creating, modifying or deleting workflows or executions
• Workflow creation, modification and execution actions taken by users are logged
• PoC has been demonstrated to users and stakeholders at Tech Fortnightly
• Broad Kubernetes permissions are not required to use the workflow

---

User Comms Plan (if applicable)

Briefly describe how you’ll let users know about the change.
