xlskubectl integrates Google Spreadsheet with Kubernetes.

You can finally administer your cluster from the same spreadsheet that you use to track your expenses.


git-sync is a simple command that pulls a git repository into a local directory, waits for a while, then repeats. As the remote repository changes, those changes will be synced locally. It is a perfect “sidecar” container in Kubernetes — it can pull files down from a repository so that an application can consume them.


HULL is a Helm library chart called “The incredible HULL — Helm Uniform Layer Library.” It is designed to improve Helm chart based workflows. The HULL library chart serves as a uniform layer to streamline the specification, configuration, and rendering of Helm charts. It allows Kubernetes objects and their properties to be specified transparently in the values.yaml file, eliminating the need for customized YAML template files.


Bash script that enables you to aggregate (tail/follow) logs from multiple pods into one stream. This is the same as running “kubectl logs -f “ but for multiple pods.

What’s new in cloud native

Terraform 1.8 Adds Provider-Defined Functions, Improves AWS, GCP, and Kubernetes Providers

HashiCorp has released version 1.8 of Terraform, their infrastructure-as-code language. The release introduces provider-defined functions. This enables the creation of custom functions within a given provider that handle computational-style tasks. Several providers, including AWS, GCP, and Kubernetes, have introduced new provider-defined functions alongside this release. Version 1.8 also introduces improvements to refactoring across resource types.

OpenTofu Launches 1.7 Release Including Long-Requested State Encryption

Features new to OpenTofu 1.7 include:

  • State Encryption, which protects sensitive state-files at rest. This feature brings industry-standard AES-GCM encryption with local passphrases and cloud integrations for key management systems such as AWS KMS, GCP KMS, OpenBao, and comes with an extensible API for future integrations.
    - Provider-defined Functions, which let providers define custom functions to be used in tofu code. This includes tofu-exclusive features enabling the authoring of dynamic custom functions in Go, or Lua code, next to a user’s tofu config files.
    - Loopable Imports, which enable the use of `for_each` in import blocks, making the importing of large amounts of infrastructure into tofu configuration much easier.
    - “Removed” blocks, which make it easy to export infrastructure from user tofu configs.
