What should you do when you’ve developed and installed a cron job for your Kubernetes application, and you need to test it?

At Crafty Penguins, we work with software development teams to automate their processes and infrastructure, so that they can deploy software updates at least daily instead of monthly or yearly, all the while maintaining a high level of up-time and security.

In our client’s DevOps journey, we are shooting for an efficient, stable, and reactive development-to-production workflow in your infrastructure. Let’s talk about the Continuous Improvement/Continuous Development (CI/CD) phase along the journey!

We’ve talked already about two parts of the journey: “Works for me” and Continuous Improvement / Continuous Development (CI/CD). This time, we’ll talk about the importance of an effective staging environment in which to test a bunch of stuff before going into production.

We’ve talked about why stuff breaks in the production environment when it didn’t in development (see “Works for me”), how Continuous Improvement / Continuous Deployment helps in failure detection, and how we can set up a “like-production” staging environment in which to test your features.

We have talked about specific types of pain: things breaking in the production environment that didn’t in the development environment, which we called “Works for me;” taking too long to get features out the door, which we solve with continuous improvement / continuous development; and the pain of not having a staging environment in which to properly test features before rolling to production.

This is the last post in the 6-post series on the Crafty Penguins DevOps Journey we take our clients on.

Grafana has a lot of cool built-in drivers for connecting and running SQL against databases. You can see at a glance literally anything you can think of.

Trickster is a reverse proxy cache for the Prometheus HTTP APIv1 that dramatically accelerates dashboard rendering times for any series queried from Prometheus.

Kubernetes is all the rage right now for several reasons: It’s the industry standard for deploying containers in production, it’s the new go-to in managing virtualized infrastructure, developers seem to love it, and it can run any containerized application (thanks to Cynthia Harvey for organizing these thoughts).

Continuous improvement and continuous development (CI/CD) is a landmark of solid Linux and DevOps work, specifically in Kubernetes and Jenkins.

We’ve collected a bunch of videos which explain all the new major features in one of our long-time favorite SQL databases – PostgreSQL.
