Streamlining Kubernetes Management: Botkube ChatOps

Hey there, Kubernetes enthusiasts! Let's dive into the world of Botkube and its game-changing. Developed by the wizards at Kubeshop, Botkube is not just another tool—it's a revolution in Kubernetes management.

If you're in DevOps, you know the headache of debugging production issues, especially when juggling massive Kubernetes clusters. The complexity can be overwhelming, right? This post will give you the lowdown on Botkube’s Helm magic and its impact on your Kubernetes adventures.

🔎 Facing the Debugging Challenge: Imagine dealing with a maze of applications relying on various system services. This scale makes it challenging to see what's going wrong when major issues crop up. Plus, there are always many tools to manage, and collaborating across different teams is only sometimes a walk in the park.

🛠️ Botkube to the Rescue: Enter Botkube! This nifty tool is like having a Swiss Army knife for Kubernetes troubleshooting. It's an app that makes monitoring, debugging, and managing Kubernetes clusters a breeze. It hooks up with your favorite chat tools, like Slack or Microsoft Teams, turning them into a command center. You get real-time alerts, can mess around with deployments, check logs, and even use kubectl and Helm from your chat window!

Ready to dive into the hands-on demo where we use Botkube for Kubernetes troubleshooting? Here's how to get started:

Step 1: Signing Up for Botkube

• New Users: If you're new to Botkube, welcome aboard! You can sign up for a free account using your email or GitHub account. It's quick and easy.
• Existing Users: Already part of the Botkube family? Just log in with your existing credentials, and you're good to go.
• You can expect your dashboard to be like this:

Linking Your Kubernetes Cluster to Slack: Now that you're in, let's connect your Kubernetes cluster to Slack for real-time monitoring magic.

Step 2: Setting Your Instance

• Click “Create an Instance” and run the below commands in your terminal.
• Homebrew is the easiest way to install the CLI tool. Alternatively, you can download the binary directly for your system or use helm commands for installations.

1. Install the Botkube CLI

Use Homebrew to install the latest Botkube CLI:

```brew install kubeshop/botkube/botkube```

Alternatively, download the Botkube CLI binary and move it to a directory under your `$PATH:`

```
curl -Lo botkube https://github.com/kubeshop/botkube/releases/download/v1.7.0/botkube-darwin-arm64chmod +x botkube && mv botkube /usr/local/bin/botkube
```

2. Install Botkube on your cluster

Install or upgrade Botkube and connect it to Botkube Cloud:

```
botkube install --version=v1.7.0 \
--set config.provider.endpoint=https://api.botkube.io/graphql \  
--set config.provider.identifier=b2b56b7d-392a-4614-b1ba-93eb0e92f424 \  
--set config.provider.apiKey=key:1d4ffcee-9df8-489c-bcd2-f288eb781dde
```
Now, Choose a display name for your Botkube instance. This is like giving a cool nickname to your new digital helper.

Step 3: Choosing Your Integration Method

• Time to pick your integration method. As we know, Botkube provides multiple integrations, but I’m using Slack Integration here because I use it a lot for personal and community use.
• Go for the "Official Botkube Slack" option. Heads up, though – this requires a 30-day free trial sign-up. It's like a test drive for the whole experience!
• It also provides a free version if you want to set it up yourself.
• You can also check the official documentation for Botkube Integration with other chat platforms.

Step 4: Syncing with Slack

• Jump into your Slack app settings. Look for the "Add Slack" button and give it a click. This is where the real magic begins – integrating Botkube with your Slack world.

Step 5: Selecting Your Slack Workspace

• Head on to the Slack console and Create an app from an app manifest.

Pick a workspace of your choice where you want to install the Botkube

You can use the manifest YAML file below for app creation.

Choose the Slack workspace where you want Botkube to be your sidekick. Now you can bridge the gap between Slack and Kubernetes, bringing them together in harmony.

You need to invite Botkube to your Slack workspace first, so click on “invite bot to channel” and add the name of the channel you want to invite Botkube from.

• Refer this documentation for more details about integrating Slack with Botkube.
• Install an App in your workspace

• Now, We need to copy the Bot token and App level token from the Slack Console that is required afterward.
• Bot Token is directly available on Slack console - Oauth token.
• App Token can be created as follows:

1. Select the Basic Information link from the left sidebar and scroll down to the App-Level Token section. Click on the Generate Token and Scopes button.

2. Enter a Name, select `connections:write` scope, and click Generate.

Export slack tokens from your terminal as follows:

```
export SLACK_API_BOT_TOKEN="botToken"
export SLACK_API_APP_TOKEN="appToken"
```

• You need to make sure you’re adding Botkube to your channel where you’ll be using Botkube, as shown below.
• After installing the Botkube app to your Slack workspace, you could see a new bot user with the name "Botkube" added to your workspace. Add that bot to a Slack channel you want to receive notifications in. You can add it by inviting @Botkube to a channel.

We’re going to install Botkube on our Kubernetes cluster now. Run below commands:

You should expect the output as given below:

Step 6: Bringing Botkube to Your Channels

• Want Botkube in your private Slack channels? No problem! Just use the "Add to Channel" feature. This way, Botkube becomes part of the conversation, ready to assist in Kubernetes-related discussions and incident management.
• It’s time to head on to our web platform for Botkube, where we can now easily select the channels where we’ve already installed Botkube.

Step 7: Customizing Your Plugins

• The final touch is selecting the plugins you want to use. This is like picking the right tools for your toolbox. Choose the ones that best fit your Kubernetes monitoring and troubleshooting needs. It's all about making Botkube work for you and your team.
• We had already configured Helm and Kubernetes in the above commands. If you have other use-cases, you can explore argocd, flux, keptn, etc. plugins. All the best 🚀

Create Instance by making changes:

Congratulations! You're all set up with Botkube Cloud and Slack. Now you've got a powerful ally in managing your Kubernetes clusters right within your Slack workspace. Go ahead, give it a spin, and see how it transforms your workflow!

Go to your Slack workspace, you can expect below updates automatically!

Verify Botkube Installation

In Slack, try running kubectl commands under the kubernetes channel like this `@SLACK_APP_NAME kubectl get nodes`

Debugging Botkube

Most likely, you’ll come across some common errors around slack channel name or botkube not recognizing your slack workspace channels. To resolve this, you can manually edit the botkube YAML configuration file.

- Configure Botkube by editing the values.yaml file.

```
vi botkube/values.yaml
```

Enable socketSlack: under ”communications:” and set the name of the default channel to match the name of your actual Slack channel. Set the botToken and appToken values to the tokens you retrieved from above.

```
communications:
 'default-group':
   socketSlack:
     enabled: true
     channels:
       'default':
         name: 'kubernetes'  ...
                                                          ...
     botToken: 'BOT_TOKEN'
     appToken: 'APP_TOKEN'
```

Enable the Helm and Kubectl executors

```
executors:
 k8s-default-tools:
   botkube/helm:
     enabled: true
       ...
...
       ...
   botkube/kubectl:
     enabled: true
       ...
...
```

Alternatively, You can also use helm for the Installation process for efficient Kubernetes application management.

Botkube Meets Helm
