tmux in GCP Cloud Shell

Thu, 07 May 2020 00:00:00 +0000

GCP Cloud Shell runs tmux. And if you’re a regular user of both, then this instructional screencast explores effective workflows and setup.

Background & Rationale

GCP Cloud Shell has many high-leverage use cases:

Executing long batch jobs or cloud-to-cloud data ETL pipelines.
Mitigating unreliable mobile or intermittent connectivity without losing running sessions.
Having an authenticated, pre-configured Google Cloud SDK environment available immediately from any browser.

Pairing it with tmux provides a consistent, resilient terminal multiplexing experience across diverse client environments.

DNS, the DevOps Way

Sun, 03 Feb 2019 00:00:00 +0000

At a DevOps Cape Town meetup, Gareth Dwyer presented a simple set of tasks that sparked an essential discussion: “Is this the DevOps way?”.

Email and backoffice DNS often suffer from brittle registrar web interfaces. Applying DevOps principles to DNS boils down to two clear objectives:

Transparency: Avoid ambiguity over who changed what, when, and why.
Reliability: Automate zone validation, syntax testing, and deployments.

The GitOps Flow for DNS

By treating zone files as Infrastructure-as-Code (IaC), DNS records originate from a version-controlled repository, while automation handles deployment.
