Quick Answer (Verified 2026): To configure Adminer for Oracle on Alpine Linux, you must install the Oracle Instant Client and the PHP OCI8 extension. This requires specific build tools and libraries like libnsl, libaio, and libnsl2. Follow the Dockerfile guide below to build a lightweight, secure container for Oracle database management. 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. ...

I ran into a small problem recently when I was leveraging my site updating code referenced in Automating Static WordPress Updates. The problem was that I was unable to update content reliably for two reasons: The content was not properly switching out the hostname in the URL when I would crawl my backend WordPress site. I actually implemented something that helped to correct this but it lead to problem #2. I should probably post a new article on the changes I made in my script… My script would only crawl the external static site so updates were not getting published. This lead me to creating this post! Now that I have the problems covered, let’s get right to it. In order to resolve the issue, I needed my Kubernetes to have split DNS for certain hosts. I needed my static site updating script to be able to crawl my backend WordPress and NOT crawl the public facing static site. ...

I recently had to do some tinkering in Oracle Cloud Infrastructure (OCI) with Compute Instances and the Key and Secrets Management in Oracle Vault. I wanted to be able to replicate AWS EC2 instance capability to access secrets based upon the instance’s permissions without requiring any usernames, passwords, tokens, etc… to be stored on the instance itself. In AWS, I already know how to do this via IAM Roles and Policies. Before we begin, I’m assuming that you already have created a Vault and Secret that will be accessed. You can reference the Oracle Cloud documentation on creating secrets and vaults here. I also assume that you have a Compute instance created that is running some type of Linux. Mine is running OL8. ...
