So I ran into an issue today, I was deploying TAP on a TKGm cluster on-prem and I went with one of the available t-shirt sizes for my nodes — After I deployed TAP I noticed that the buildservice kept failing so I started to do a little troubleshooting, and when I checked the events I noticed that their were errors regarding disk pressure on the nodes and the pods being evicted, and then I remembered that TAP requires a minimum of 70GB of disk space on the worker nodes and I only had 40GB.

So at my new job I’ve been learning TAP(Tanzu Application Platform) and as apart of that I’ve had to setup a domain so I can build new apps and serve them from that domain, so obviously I just picked a domain from a list of domains that I own, and the domain I chose was alexanderbrash.dev; simple enough, but then I noticed that when I tried to access the TAP GUI in Chrome or Firefox I was getting redirected to the https version of the site and of course I hadn’t setup any certs or anything I was just messing around, even if I used an incognito window or tab, same thing, every time I would go to http://tap-gui.

So I just had to renew my letsencrypt certificate for my VCSA and ran into a few issues and I wanted to write them down here, so I will go through creating the cert and adding it to your VCSA in the below blog post. I will assume you have certbot only installed on your machine Let’s create our cert certbot certonly -d myservice.domain.com --manual --preferred-challenges dns --agree-tos -m mail@mail.com Of course make changes as needed from the above command, then follow the instructions to add a TXT record to your DNS provider Now comes the tricky bit of assemblying the certificate in a way that your VCSA will accept it and not choke, the below blog helped out quite a bit.

It’s been a while since I’ve posted on here but I’ve been quite busy, I’ve started to study for my CKA, plus I’ve been doing some React/Next.js/Redux work. I’ve built a couple of apps and I’m hosting them on Vercel check them out below. Hulu 2.0 Tesla Clone I hope to add some more to the above list, one app I’m thinking about is building a crypto bank app using Next.

Well after thinking about migrating from Wordpress I’ve actually done it, I’ve migrated the blog over to Hugo a static site generator; I will have a full write up on the reasons behind me migrating off of Wordpress but for now I just wanted to write something quick and get the infra in place to make the move. More to come…

So I ran into an interesting issue today, I had provisioned a new k8s cluster using kubeADM but I replaced docker with containerD, everything was smooth and then I deployed prometheus and grafana using helm, and I noticed that I couldn’t connect grafana to prometheus I had installed istio so I thought that was the issue, maybe by default istio was messing with the pods network communication, but I also noticed that when I tried to install a dashboard from grafana I received an error, so the container couldn’t reach grafana.

So that didn’t take long, after only 24 hours I’ve run into my first issue thankfully the fix was simple. When I went to create a post or edit a post I kept seeing the following error message “Updating failed. Error message: The response is not a valid JSON response.” After some Googling around I found this thread https://wordpress.org/support/topic/updating-failed-error-message-the-response-is-not-a-valid-json-response-2/ scrolling down I found my answer, head back to admin settings & permalinks and re-save your settings I changed mine so WordPress can respond to API calls, well apparently something funky happens to those settings after the upgrade and you need to just hit the save button again.

I’ve upgraded WordPress to v5.5.1 let’s see how many issues I run into, every time I do an upgrade I find little crazy bugs.

I’ve passed my CKAD! this is a little delayed because I’ve been super busy.
