Attempt to replace hedge’s member tracking with hashicorp/memberlist
2023-04-28
I recently came across the hashicorp/memberlist library while browsing GitHub and I thought it would be a good replacement for hedge’s internal member tracking logic. It seems to be widely used (thus more battle-tested) as well. I was quite excited as I always thought that hedge’s equivalent logic is too barebones and untested outside of our use cases. It works just fine for its current intended purpose but I’ve been hesitating to build on top of it until I can really say that it’s stable enough.

Automate Spanner backup using Kubernetes CronJob
2020-09-11
As of this writing, GCP doesn’t have an option to create Spanner backups automatically. This could be available when you’re reading this in the future. At the moment, however, if you’re using Kubernetes, you can utilize CronJob to do a scheduled backup. Here’s a sample CronJob deployment that uses gcloud to create the backups. First, you need to create a service account that has permissions to create Spanner backups. Once you have downloaded the JSON file for the service account, store it as a Kubernetes Secret.

Extending the timeout of a Kubernetes service in GCP
2019-11-28
This is related to a previous post about Kubernetes services. This time, it’s about extending the timeout of an Ingress. We had a situation where we had to download a huge file from one of our exposed services. The download takes about two minutes to complete. This didn’t really worked out since by default, GCP load balancers that are associated with k8s Ingresses have a timeout value of 30s. For a time, we just did manual updates by going to the GCP k8s Services and Ingress console, opening the backend service under the Ingress, and editing the Timeout section to the desired seconds.

Using stern together with grep
2019-09-30
I’ve been using stern as my goto log viewer for Kubernetes. It supports multiple pods and other convenient functions on top of kubectl logs. And of course, grepping goes hand in hand with log viewing, doesn’t it? To combine grep with stern, I use the following commands: For OSX: # stern <some-prod-prefix> | grep -i –line-buffered -E '<extended-regex>' $ stern user | grep -i –line-buffered -E 'failed' # For Linux (Ubuntu specifically): # stern <some-prod-prefix> | grep -i -E '<extended-regex>' $ stern user -s 1h | grep -i -E 'error'
