The MySQL replication sample built on a StatefulSet in the Kubernetes documentation is the easiest way to see a stateful database running on a cluster: one primary pod, replica pods, and a sidecar tha...
A MySQL pod on LKE sits in the ContainerCreating state after you delete the pod or change nodes. There is no application log because the container never ran, and kubectl get pod only shows ContainerCr...
Almost every language model you hear about today, from BERT and PhoBERT to text-generation models, is built on the same architecture: the Transformer. This article does not argue which model is "smart...
An e-commerce order moves through several states: new, paid, shipped, delivered, cancelled. Each action, such as paying, shipping or cancelling, is valid only in certain states, and the behavior diffe...
Once an application runs on Kubernetes, the manual process of "build the image on a personal machine, push it to Docker Hub, edit the manifest, then kubectl apply" soon becomes a bottleneck. If the so...
In the previous article, TF-IDF treated "ô tô" and "xe hơi" (two Vietnamese words for "car") as two completely separate columns: nothing says they mean almost the same thing. The model only knows the...
A single Laravel pod cannot handle heavy traffic, so you raise replicas to 2. The first pod runs, the second one is stuck at Init:0/1 and reports Multi-Attach. The cause is almost always the same: bot...
One failure mode is especially annoying when you move Laravel to Kubernetes: the ConfigMap is correct, the pod has restarted, and the application still runs with the old value. Or a page works on the...
The two blocks that get edited back and forth the most in the manifest of an application newly moved to Kubernetes are resources and affinity. The cause is usually the same: not fully understanding ho...
A news site receives several hundred stories a day and must file each one under the right section. An online store has to sort customer feedback into "delivery", "payment" or "warranty". Both are text...
Once the cluster has ingress, automatic certificates and applications running smoothly, questions like "are the nodes getting full", "which pod uses the most RAM" or "was anything unusual last week" c...
An order entering the system has to pass several checks: is the customer logged in, is the item in stock, does the payment exceed the limit. If you write all of that in one long method full of nested...
