A Laravel website had just started running against a MySQL 8 pod in Kubernetes when pages slowed down and then hung. The application log showed error 1114: The table '/tmp/#sql...' is full, even thoug...
A website returning 502 can be failing because of nginx on the balancer, PHP-FPM on the minion, a query locking a table on the database, or, on Kubernetes, a pod that was just killed for exceeding its...
If your cluster has Prometheus and Grafana but no per-pod alert rules, you usually learn that a pod is running out of RAM only when the site already returns 503. This guide closes that gap in three st...
A site returns 503 from ingress-nginx, yet kubectl get pod still shows Running, and CPU and RAM on Grafana are both low. The common reflex is to suspect that the pod ran out of memory and was killed....
A Laravel pod runs nginx, PHP-FPM, cron and a queue worker in a single container. Even when nobody visits the site, kubectl top pod still shows a noticeable baseline of RAM and CPU. Then comes load te...
After Embeddings and semantic search: sentence-transformers and FAISS, every project hits the same next question: where do the vectors live once the data grows, gets edited, gets deleted and has to be...
A Laravel site's image already contains the code, themes, plugins and assets. But when you attach a volume mount to the exact directory that holds them, to keep uploaded files, the pod starts and then...
Most order systems we run into share the same symptom: classes like Order, Customer and Product are just bags of getters and setters, while every business rule is scattered across services. Money is a...
Running a single-node Elasticsearch in Docker takes one docker run command. Move the same setup to Kubernetes and things start to drift: the pod sits in Pending, FailedMount events appear and vanish,...
A pod runs as the nginx user (not root), mounts an NFS directory, and every subdirectory is owned by root. The chown command in postStart changes nothing, and the cache reports permission denied. An e...
A Laravel pod starts normally, but as soon as it writes a log, a cache entry or an uploaded image, a permission denied error appears: Failed to open stream: Permission denied on storage/framework/cach...
Once one product runs well on Helm, other Laravel projects want to move to Kubernetes too. Copying the chart and editing it by hand is the fastest way, but it produces many near-identical copies that...
