A Laravel website running on Kubernetes starts returning 503 over and over. The pods are still Running and are not restarting, but the event Readiness probe failed ... context deadline exceeded keeps...
The search box on most websites still matches keywords: a customer types "drop my order" (the colloquial Vietnamese phrase), the system finds no such word in the article "How to cancel an order," and...
You install mysqld_exporter with Helm and the pod reports 1/1 Running, but Prometheus either shows no target, or shows a green target while the graphs stay empty. None of the three errors below prints...
Open Cloud Manager, click through creating a cluster, create an NFS machine, then SSH in to install the rest: doing it once is quick, doing it a second time is where mistakes start. This document show...
The application reports SQLSTATE[HY000] [2002] Connection refused while the MySQL Service still has an address and answers ping, and the pod's CPU and RAM are completely normal. This is the typical sh...

Once the sites on Kubernetes are created with GitLab CI, sooner or later you need other tasks too: back up one site, back up the whole cluster, remove a site, clean up after a failed creation. Instead...
A fairly common situation: the code lives on Bitbucket, where developers work with branches and pull requests, while the pipelines that operate the Kubernetes cluster (creating sites with Helm, workin...
