| TIP Controller Local Deployment |
microk8s Install
Base System
A snap capable operating system is required for microk8s installation. TIP Controller has been installed on an Ubuntu 20 system with 32Gb memory, 500Gb disk and Gigabit Ethernet network interface with a user account tip created.
The system should have a fully qualified domain name and the deployment of TIP controller will require additional DNS records to be created.
$ sudo snap install microk8s --classic --channel=1.19
{% hint style="info" %} The above specifies microk8s 1.19 release will be installed {% endhint %}
Set user permissions
sudo usermod -a -G microk8s tip
sudo chown -f -R tip ~/.kube
{% hint style="info" %} source or re-login to shell for environment to be applied {% endhint %}
Setup microk8s
microk8s enable helm3 dns storage metallb
{% hint style="info" %}
metlalb will request an IP address range. Specify the IP of Gigabit Ethernet interface.
If you interface address is 10.1.1.1 then provide metallb with: 10.1.1.1-10.1.1.1
{% endhint %}
Begin Controller Setup
TIP Controller may be deployed with self-signed certificates for a local lab environment. The following steps will guide the reader through that process.
Install Keytool
sudo apt install -y openjdk-11-jre-headless
sudo apt install -y default-jdk
Enable Firewall to permit Controller traffic from Container Network Interface
sudo ufw allow in on cni0 && sudo ufw allow out on cni0
sudo ufw default allow routed
Downloading TIP Controller Software
{% hint style="info" %} Change to a directory for configuring certificates and running controller. This can be within the tip home directory. {% endhint %}
Obtain Controller PKI Certs Locally
git clone https://github.com/Telecominfraproject/wlan-pki-cert-scripts.git
Obtain Controller Locally
git clone https://github.com/Telecominfraproject/wlan-cloud-helm.git
From the current directory, two sub-directories now exist for wlan-pki-certs and wlan-cloud-helm.
Create necessary self-signed certificates. No changes are necessary to deploy the controller. However if changing the organization name is desired this may be done by editing the .cnf files for all certificates of the system. Once complete generate the service certificates and copy these to the controller.
cd wlan-pki-cert-scripts
./generate_all.sh
./copy-certs-to-helm.sh ~/wlan-cloud-helm/
Deploy Controller
TIP controller defaults to a domain of wlan.local. It is possible to operate a lab DNS service permitting local resolution of this domain for the TIP controller services. Certificate instructions for a self-signed private domain will follow in a subsequent release of service and documentation.
cd ~/wlan-cloud-helm
microk8s helm3 install tip-wlan tip-wlan -f tip-wlan/resources/environments/dev-microk8s.yaml -n default
Helm will deploy the Controller containers within a TIP namespace to microk8s on the machine.
Check Controller Status
microk8s kubectl get services -n tip
microk8s kubectl get pvc -n tip
microk8s kubectl get pods -n tip
{% hint style="info" %} Get svc will return the network Services of each container port maps as well as list of containers mapped to external IP address defined during the metallb config stage earlier.
Get pvc will return the Persistent Volume Claims of the containers to the microk8s storage service
Get pods will return the current state of all containers. The controller will require two to four minutes for all pods to reach 'Running' state. {% endhint %}
Examples of all three commands:
tip@microk8slocal:~$ microk8s kubectl get svc -n tip

Access Point Self-Signed Keys
In the earlier stage when self-signed keys were created for the controller, keys were also created to support Access Point connections over SSL to the newly deployed controller.
To obtain these keys, return to the wlan-pki-cert-scripts folder and copy these Access Point keys using secure copy (SCP) to each. Note the filenames change when copied to the device.
cd ~/wlan-pki-cert-scripts
scp cacert.pem root@:/usr/opensync/certs/ca.pem
scp clientkey_dec.pem root@:/usr/opensync/certs/client_dec.key
scp clientcert.pem root@:/usr/opensync/certs/client.pem
{% hint style="info" %} The above assumes the microk8s system has IP connectivity to the Access Point {% endhint %}
Directing Access Point To Controller
In the current release of a TIP Controller using self-signed certificates, Access Points communicate to the TIP Controller using OpenSync. Access Points are directed to the controller at this time using local configuration.
The default TIP Open AP username and login are 'root' and 'openwifi'
/bin/wlan_ap_redirector.sh ssl:<IP or FQDN of controller>:6643
{% hint style="info" %} The IP address (or FQDN) are the same as the metallb exposed External IP as shown in earlier steps {% endhint %}
