+# Support bundle
+
+For the Alpha.1 release, MKE 4 deploys k0s v1.29.3, which does not inherently support Replicated's [support bundle tool](https://troubleshoot.sh/docs/support-bundle/introduction/).
+
+To manually collect a support bundle, you can use the following steps:
+
+- SSH into the manager node.
+- Download and install the `support-bundle` tool:
+  ```shell
+  curl -L https://github.com/replicatedhq/troubleshoot/releases/latest/download/support-bundle_linux_amd64.tar.gz | tar xzvf -
+  ```
+- Create a YAML file that describes the support bundle configuration. For example, create a file named `support-bundle-worker.yaml` with the following content:
+```yaml
+  apiVersion: troubleshoot.sh/v1beta2
+  kind: SupportBundle
+  metadata:
+    name: sample
+  spec:
+    collectors:
+      - logs:
+          selector:
+            - app.kubernetes.io/name=boundless-operator-webhook
+        namespace: boundless-system
+        name: logs/boundless-system
+      - logs:
+          selector:
+            - control-plane=controller-manager
+          namespace: boundless-system
+          name: logs/boundless-system
+  ```
+  This configuration collects the following information:
+  - Cluster information
+  - Cluster resources
+  - Logs from the `boundless-operator-controller-manager` and `boundless-operator-webhook` pods will be stored in the `logs/` directory of the output.
+
+Another option is to collect host information by utilizing the YAML file provided by k0s in https://docs.k0sproject.io/stable/support-bundle-worker.yaml
+
+- Run the `support-bundle` tool:
+    ```shell
+    ./support-bundle --kubeconfig /var/lib/k0s/pki/admin.conf <support-bundle-worker.yaml>
+    ```
+    NOTE: 
+    - The `support-bundle` tool requires the `kubeconfig` file to be passed as an argument. The `kubeconfig` file is located at `/var/lib/k0s/pki/admin.conf`.
+    - The support bundle will be saved to a file named `support-bundle-<timestamp>.tar.gz`.
