DigitalOcean can find the GitHub repository and still fail the deployment when the source directory, build command, or output directory points at the wrong place. I kept the sample at a root index.html because that removes two decisions from the…
minikube stopped at the first command on the one-CPU machine I ran it on, and the message named my core count. The cluster it starts puts the Kubernetes control plane and the workload on one Node, because a local cluster…
Jenkins runs the commands you would type by hand, on a machine that stays up after you close the laptop. I ran a Node.js pipeline on Jenkins 2.568.3 and the build finished green while the deploy step failed twice, once…
A release carries three separate things to production: the artifact you built, the configuration the process reads at startup, and the instance that takes traffic. I ran all three on this server with a small Node.js service and a router…
A pod that keeps dying has already written down why. The exit code, the event list, and the container’s last line of output are sitting in the cluster, one command apart. Kubernetes troubleshooting tools earn their install when they reach…
The console test passes and the live request still comes back as an internal server error. The JSON you typed in the Test tab is not the request object an HTTP trigger sends, so the handler that worked in the…
The heap graph shows a few hundred megabytes against a one gigabyte limit, the application log is empty, and the pod restarted with exit code 137 anyway. I ran a small Java service in a 256 MiB container with a…
My first cached request came back with a MISS in the status header, and nothing in the configuration or the error log said whether the cache was working or ignoring that response. So I built the setup again on Nginx…
A URL shortener is two writes and one read, and those writes decide how long the link you handed someone keeps working. Redis counts that lifetime down on its own, which means a route handler that looks correct today can…
Install the mysql package, point it at MySQL 8, and the handshake dies with ER_NOT_SUPPORTED_AUTH_MODE. I reproduced that against MySQL 8.4.11 and MySQL 9.7.2 before a single query reached either server. mysql2 speaks the same protocol, adds a promise API…
