Home (development) automation project

 It's been a long time since I posted here. My goal is to post a blog entry once a week. 

Currently I am working on creating a Minikube stand alone server using VMware workstation. I am running Ubuntu 24.01. So far things are going well. I am documenting the steps to setup Minikube using Notebook LM. I really like Notebook LM, the AI chat is pretty good. 

Back to the Minikube project, I have a few items I need to research. My goal is to complete the following 2 items next week or at the very least, learn enough to know if I need to change my approach.

• Stop using DHCP for the bridge network adapter for the VMWare Ubuntu VM. I'm able to work around this using the DNS name. However, when running the dashboard-proxy, I get failures due to the IP address changing. 
• This should be pretty easy, I just need to figure out the DHCP range my router uses and choose an IP that is not within the range.
• While I was able to connect to some services, I would like to learn more about the egress and hopefully use third level domain naming.
• This will take some time, I haven't tried customizing a DNS server. I have the basic concepts on how DNS works, but I am excited to learn how that works!

For reference, this is the dashboard-proxy error

error: error upgrading connection: error dialing backend: tls: failed to verify certificate: x509: certificate is valid for XXX.XXX.XXX.20, <IP6-address>, not XXX.XXX.XXX.43
