I recently needed to setup Content Security Policy (CSP) on a website and I couldn’t think of where to get started. The first question that came to mind was what all content do I allow and how do I test everything without having to look through all of the code on the site. This is where the Content-Security-Policy-Report-Only header can come into play. The short version is that this allows you to create a policy in report only mode and you can collect the results at the endpoint specified via the report-uri directive. That’s great! I have what I need but how do I collect what’s being reported by the clients to the report-uri and what do I use for the report-uri? This was a great place for me to begin testing out DigitalOcean Functions. ...

I wanted to be able to curate some of my favorite RSS feeds into a single location. There are an endless number of RSS readers and ways to do it but I wanted to use Slack since it’s on every device I use. Using Slack would also allow me to get notifications wherever I was. I could also easily share these articles with anyone that I thought would want to read them. ...

If you are not familiar with adminer, you can read more about it here. In short, it is a PHP script that allows you to manage various databases via a single interface. We have been successfully using the adminer official docker image from docker hub for a number of different databases. We now have a need to add Oracle as one of those databases to use with adminer. This initially seemed like a simple task. The docker hub page states ...

Now that I’m beginning to use Github to manage my Kubernetes cluster as shown in my previous article Making The Leap Into Devops, it’s time to start bringing over some of my sample systems for testing. This article shows how to make use of Bitnami’s PostgreSQL helm chart to deploy a sample PostgreSQL database in Kubernetes. I make use of the PostgreSQL DVDRental Sample Database that is available here. In order to incorporate this into my deployment, I have created a public Github called sample_dbs to host my sample databases. I pull this down into the deployment so that I have a sample database. ...

It is time for me to quit managing all of my Kubernetes configurations on a random number of servers and Git repos. Sadly, my usage of the Git repos has ONLY been used to perform backups of my code and not used as a way to manage configuration changes. I have been running in DigitalOcean’s infrastructure since 2017, Member since 1/14/2017. I’ve steadily moved from just Droplets into their more managed infrastructure to include Kubernetes and App Platform. The App Platform is what sits in front of this website (something I’ll need to further document some day). I’m hoping to get some time to also tinker with their Functions but time is not always on my side. ...
