A PersistentVolume with persistentVolumeReclaimPolicy: Retain (not applicable for Delete) used by a PersistentVolumeClaim transitions from Bound to Released state when the attached PVC is deleted. If you try to create a new PVC and bind that to the same PV, the PVC will continue to be in Pending state and the PV in Released state. […]
You can run kubectl describe pvc [pvc_name] and look at the Used By label to find out the list of pods using that particular PersistentVolumeClaim in your Kubernetes/K8S cluster’s namespace. The myclaim pvc above is being used by pod-1 and pod-2 in the test namespace. Sometimes it might be useful to go through all the […]
gcloud builds submit command submits a build to the GCP Cloud Build service and uses the Dockerfile from the build context. Sometimes, we may want to specify the Dockerfile while running the command. For instance, in one of my projects, I have Dockerfile.stage and Dockerfile.prod that I want to use separately with gcloud builds submit […]

This file includes the URL, authentication details, etc. The […]
Google Cloud Platform (GCP) offers a product called Identity-Aware Proxy (IAP) that helps guard access to your applications running on App Engine, Cloud Run, Compute Engine, GKE or On-premises (outside GCP in your own data centres or a different cloud provider). Think OAuth-based authentication right at the load balancer level before a request is able […]
Recently I was trying to figure out how to generate an ID Token using the Firebase Admin SDK but it seems like there’s no direct function exposed by the SDK that allows that. Instead, we can use the GCP Identity Platform REST API, which Firebase Auth is also based on, to exchange a custom token […]
One of my Compute Engine VM instances on GCP with a boot disk of 10GB suddenly stopped accepting SSH connections. This was really weird. So I tried troubleshooting (as seen in the output above): So it turned out that I could not SSH because my boot disk was full. Entire 10GB of disk space exhausted! […]
If you are running an application on a GCP Compute Engine VM instance and want its logs to be collected and streamed into Cloud Logging, then you will have to use an agent that GCP provides called Ops Agent. It’s a single agent that uses Fluent Bit for logging and the OpenTelemetry Collector for metrics […]
Some commonly asked questions are: To understand these limits, let’s first look at what the official specification, i.e., RFC 6265 has to say. According to it, a browser must provide a minimum of the following: We know the minimum limits now. As far as maximum limits are concerned, it doesn’t really matter because each browser […]
