I have a few old Intel NUC computers so I decided to try to set them up with MaaS, but I’m a bit out of my element with the setup and I’m hoping someone can help me out. My ultimate goal is to set up a Kubernetes cluster to use for scaling up CI builds and get some experience with cloud computing concepts.
Hardware-wise, I have the following:
- An Intel NUC8i7BEH with Ubuntu Desktop 18.04 (“manager”)
- A few Intel NUC5i5RYH’s to serve as the nodes. I configured them for network PXE boot.
I connected the network components as follows:
- Manager computer connected to home router via ethernet. Set a static IP address of 192.168.1.18. Interface is
enp0s31f6
. - USB3-to-Ethernet dongle out of manager computer to basic 8-port network switch. Interface is
enxd8eb97b3e376
, but it does not have an IP address. - Node computers connected by ethernet to network switch.
- I still have the node computers powered off.
I installed maas as a snap and did the basic configuration on command line and web interface (all defaults, included launchpad ssh key). I was surprised that even though it seems like MaaS is idle I have one core of my CPU consistently maxed out, but I’m guessing it’s not relevant to my current problem.
I tried to follow the directions here (MAAS | Fresh installation of MAAS, step 6) to setup DHCP. This instruction says to select the VLAN you want to enable DHCP for, select “take action,” and then “provide dhcp.” When I get to this step there is a dialog box titled “Default VLAN in fabric-2.” The first entry item is a dropdown menu saying “Rack controller.” However, there is nothing for me to select here (just an empty menu).
Here is a screenshot of my controller interfaces summary page, if it’s helpful:
When I go to the “Nodes” menu and then “controllers,” I see I have a region controller named “ghost.maas.” If I click on it and then go to the configuration edit page, I see an error message: “Editing is currently disabled because no rack controller is current connected to the region.” I’m not sure how to connect a rack controller to the region, and I’m also not sure how to configure my network setup and subnets.
I’ve tried a lot of searching but haven’t come across others with my situation. Do I have something wrong with my configuration? Was I supposed to do some network setup before installing Maas? I would appreciate any help anyone is willing to offer, and I apologize if this is the wrong type of topic for this forum.
