Compute Resources

Because we cannot use VirtualBox and are instead using Multipass, a script is provided to create the three VMs.

1. Run the VM deploy script from your Mac terminal application

    ./deploy-virtual-machines.sh
   

2. Verify you can connect to all three (two if your Mac only has 8GB RAM) VMs:

    multipass shell controlplane
   

   You should see a command prompt like ubuntu@controlplane:~$

   Type the following to return to the Mac terminal

    exit
   

   Do this for node01 and node02 as well

If you encountered issues starting the VMs, you can try NAT mode. Note that in NAT mode you will not be able to connect to your NodePort services using your browser.

1. Run

    ./delete-virtual-machines.sh
   

2. Edit deploy-virtual-machines.sh and change BUILD_MODE="BRIDGE" to BUILD_MODE="NAT" at line 15.

Deleting the Virtual Machines

When you have finished with your cluster and want to reclaim the resources, perform the following steps

1. Exit from all your VM sessions

2. Run the delete script from your Mac terminal application

    ./delete-virtual-machines.sh
   

3. Clean stale DHCP leases. Multipass does not do this automatically and if you do not do it yourself you will eventually run out of IP addresses on the multipass VM network.

   1. Edit the following

       sudo vi /var/db/dhcpd_leases
      

   2. Remove all blocks that look like this, specifically those with name set to controlplane, node01or node02

       {
           name=controlplane
           ip_address=192.168.64.4
           hw_address=1,52:54:0:78:4d:ff
           identifier=1,52:54:0:78:4d:ff
           lease=0x65dc3134
       }
      

   3. Save the file and exit
