Learn Kubernetes Weekly issue 123
We disabled GKE image streaming, pod kills due to memory spikes, feature-branches: vanilla Kubernetes + Bitbucket pipelines, scheduling shenanigans
19 Mar 2025
This newsletter is brought to you by mirrord — run local code like in your Kubernetes cluster without deploying first.
The team behind Mirrord (sponsor of this newsletter) will be at KubeCon London 2025. If you want to learn how to develop your apps locally against a remote cluster, visit them at booth S540 or book your slot here!
Articles
Faster machine learning deployments: why we disabled GKE image streaming
PicCollage
In this article, you'll learn how disabling GKE image streaming can improve machine learning deployments by reducing deployment times.
Split Queues To Share Cloud Development Environments
Enable your team to develop and test in a shared cloud environment—without conflicts or costly staging setups.
Learn how to split incoming messages from remote queues (like AWS SQS) between your local process, your teammates' setups, and the remote service in Kubernetes.

Developing an ETL pipeline for massive NOAA sensor data: from raw files to predictive insights
Marcos Cedenilla
In this case study, you will learn how to build a robust ETL pipeline for massive sensor data that leverages Apache Spark for distributed processing and Kubernetes for orchestration.
Articles worth checking out:
Cut your dev loop from hours to seconds
Cloud development can feel like a slow, repetitive loop—writing code, deploying, testing, and fixing.
mirrord lets you run your code in real cloud conditions from the start, so you can test earlier and ship more reliable code faster.
Tutorials
How to Debug a Go Microservice in Kubernetes
This guide walks you through debugging a Go microservice while still accessing live cluster resources—so you can test and troubleshoot issues in real cloud conditions without redeploying.

Code & tools
OCM: multi-cluster orchestration
Open Cluster Management (OCM) is a modular, extensible platform for Kubernetes multi-cluster orchestration.
The multi-cluster control plane is modelled as a “Hub,” and each of the clusters being managed by the "Hub" will be a "Klusterlet.”
Kargo: application lifecycle orchestration
akuity
Kargo is a continuous delivery and application lifecycle orchestration platform for Kubernetes.
It builds upon GitOps principles and integrates with Argo CD to streamline and automate the progressive rollout of changes across an application's lifecycle.
Coroot: eBPF-based observability
Coroot is an open-source eBPF-based observability tool that turns telemetry data into actionable insights, helping you quickly identify and resolve application issues.
You can use the Kubernetes Descheduler to evict pods based on specific strategies so that the pods can be rescheduled onto more appropriate nodes.
Caretta is a tool that instantly creates a visual network map of the services running in your cluster.
Carreta leverages eBPF to efficiently map all service network interactions and Grafana to query and visualize the collected data.
