Managing Kubernetes deployments involves a variety of workflows, many of which require manual approvals to ensure safety and compliance. Approval workflows are a vital checkpoint in this process, helping teams balance automation with control. However, interrupting your workflow to toggle between tools slows teams down. Wouldn’t it be more efficient to manage approvals directly in the platforms you already use, like Slack or Microsoft Teams?

In this post, we’ll dive into how you can set up K9s approval workflows within Slack or Teams for faster, more streamlined Kubernetes operations.


Why Use Slack or Teams for K9s Approval Workflows?

Kubernetes is a critical piece of modern infrastructure, but integrating smooth approval workflows often feels clunky. When you rely on traditional methods, like switching to a command-line tool or custom scripts, context-switching and delays are inevitable.

By integrating K9s approval workflows with communication tools like Slack or Microsoft Teams, you can:

  • Reduce Context Switching: Manage approvals where your conversations already happen.
  • Streamline Processes: Approvals become part of your team’s natural flow, with real-time notifications and one-click actions.
  • Increase Transparency: Everyone gets to see when and why changes occur, directly in Slack or Teams.

This integration ensures advanced Kubernetes permissions and policies don’t slow you down.


How To Set Up K9s Approval Workflows on Messaging Platforms

Implementing approval workflows directly within Slack or Teams might sound complex, but orchestration tools like Hoop.dev make it surprisingly simple. Here's how you can achieve it step by step.

1. Authenticate Your Cluster and Messaging Platform

Start by linking hoop.dev to your Kubernetes context and the communication tool your team uses daily. For Slack or Teams, install the appropriate app integration and ensure it has the right permissions to interact with channels or users:

  • Use kubectl for access-based configuration.
  • Ensure the integration uses role-based access control (RBAC) to respect existing policies.

2. Define Approval Rules in K9s

Decide what changes require approvals in your Kubernetes cluster. Common scenarios might include:

  • Deployment rollouts to staging or production environments.
  • Changes to ConfigMaps, Secrets, or other sensitive resources.
  • Scaling resources beyond predefined thresholds.

The approval triggers are defined in your Kubernetes configuration files. If you're using K9s with hoop.dev, those rules are mapped directly into workflows that Slack or Teams can enforce.

3. Automate Notifications

Whenever workflows require approval, automation is key. With a K9s integration, triggered events send updates to Slack channels or Teams groups. These messages allow approvers to see what is happening in real time and act quickly.

A good message template includes:

  • The namespace or cluster affected.
  • The person or service causing the change.
  • Recommended next steps (e.g., approve or reject).

4. Click to Approve or Reject

From within Slack or Teams, users with appropriate permissions can approve or reject requests directly by clicking on buttons. No need to jump back to the terminal.

Approvals are logged into your centralized workflow records, ensuring compliance and transparency. With tools like hoop.dev, configuration is reusable across teams, making deployment practices uniform and error-prone steps minimal.

5. Monitor and Iterate

Integrations like these aren’t just about operational efficiency—they’re also about better insights. By monitoring your K9s approval workflows, you can identify bottlenecks while keeping audits and compliance records up to date.

Regularly review:

  • Approval timing and trends.
  • Frequency of triggered workflows.
  • Logs for rejected changes and why they occurred.

Avoid Common Pitfalls in Approval Workflows

While setting up K9s approval workflows in Slack or Teams is straightforward, some common mistakes can reduce effectiveness. Here’s what to watch for:

  • Overly Complex Rules: Avoid creating too many approval rules that slow down processes unnecessarily. Focus on critical changes.
  • Insufficient Permissions: Incorrectly configured roles in Slack, Teams, or RBAC can lead to overrides or failure to enforce policies.
  • Ignoring Auditing: Ensure all approvals and rejections are stored somewhere retrievable, even if Slack/Teams don’t inherently save every action you take.

The key is a balance between control and speed. Start simple and scale up the complexity only when needed.
