```

Update the VM configuration to set the CPU & Mem allocation

Unload the multipass config

sudo launchctl unload /Library/LaunchDaemons/com.canonical.multipassd.plist

Edit the file

sudo vi /var/root/Library/Application\ Support/multipassd/multipassd-vm-instances.json

Set the num_cores": 4 and "mem_size": "8589934592". Final JSON file would look like this.

{
   "microk8s-vm":{
      "deleted":false,
      "disk_space":"53687091200",

Steps to install gopaddle lite addon for microk8s

Enable microk8s community addon and enable gopaddle lite addon.

microk8s enable community
microk8s enable gopaddle-lite -v 4.2.9

Optional parameters while enabling the addon.

microk8s enable gopaddle-lite [-i <IP Address>] [-v <gopaddle version>] 
Basic Options: 
--ip|-i : static IP address to assign to gopaddle endpoint. This can be a public or private IP address of the microk8s node 
--version|-v : gopaddle lite helm chart version (default 4.2.5)

If -i option is omitted, then the gopaddle endpoint is decided based on the node's private IP address. Please take a look at the 'gopaddle dashboard endpoint' section for more details.

Example:

microk8s enable gopaddle-lite -i 130.198.9.42 -v 4.2.9

Make a note of the gopaddle lite access endpoint from the above command. You can also obtain the endpoint by listing the node IPs in the cluster.
Wait for gopaddle services to move to running state
```
microk8s kubectl wait --for=condition=ready pod -l released-by=gopaddle -n gp-lite
```
If you see this error message timed out waiting for the condition on pods, you can execute the above command once again to wait for all the gopaddle services to move to running state.
Access the gopaddle dashboard. If static IP is provided as an input using -i option in step 1, then accesss the gopaddle UI @ http://<STATIC_IP>:30003 , else access the gopaddle UI @ http://<NODE_IP>:30003 . The Node IP can be determined by executing the command below. If the node has a public IP, open the firewall ports in the next step.
```
microk8s.kubectl kubectl get nodes -o wide
```
Enable Firewall ports (if installing gopaddle lite on a cloud based VM)
The following TCP network ports have to be enabled/opened to use the gopaddle lite dashboard:
- Ports 30000 to 30006: for accessing gopaddle endpoints .
- Port 32000: Service node port for Grafana dashboard on Kubernetes
- Any node port assigned for an application deployed on microk8s

gopaddle dashboard endpoint

An IP address is required to access the gopaddle lite end point. When not supplied from the command line, the default IP address is determined in the order mentioned below:

If the first node in microk8s cluster is configured with an External/Public IP address, this is chosen as the IP address for the access end point
Else, the Internal/Private IP address of the first node configured in microk8s cluster is used as the IP address for the access end point

Note: The node IP address configured in the microk8s cluster above can be determined using the 'get nodes' command as follows:

microk8s kubectl get nodes -o wide
NAME          STATUS   ROLES    AGE   VERSION   INTERNAL-IP    EXTERNAL-IP   OS-IMAGE             KERNEL-VERSION       CONTAINER-RUNTIME
microk8s-vm   Ready    <none>   41m   v1.25.2   192.168.64.2   <none>        Ubuntu 18.04.6 LTS   4.15.0-194-generic   containerd://1.6.6
