cURL Quick Domain Spoof with cURL Occasionally, you need to quickly check service availability, make sure your application is alive, or retrieve a certificate using internal interfaces.
Ansible Ansible: K.I.S.S. Optimization It's fascinating, but our automation code is mature enough to have compatibility issues during the operating system upgrade. Let's see how violating the "Keep it simple stupid (K.I.S.S.)" principle leads you to trouble.
PowerShell How To Watch in PowerShell Every system administrator who runs a big system knows how to make long-running tasks less boring. Watching progress is one of those little fun things.
WebMethods WebMethods.io: Custom Transformers In previous integration posts, I briefly touched on the powerful mechanism of the Webmethods.io Transformers. Let's explore the data manipulation tools using a real-life example.
Ansible Ansible: Log Visibility Control Ansible, originally developed as a state management tool, relies on logs to track play progress and target states due to its distributed execution. Let's discuss a few methods for controlling log content and visibility.
Ansible Ansible: Ad-Hoc Shell Module I shared a tip on handling missing files in an Ansible playbook some time ago. I have now tried to do the same with ad hoc command execution. Here is how you can use extra module arguments.
Cloud Integration Webmethod.io: Implementation. Part 2. We finally get into workflow building, with all custom components and connections required for a secure Ghost Blog. Today, we will complete the overall design and error-handling process.
ChatGPT Webmethods.io meets ChatGPT Creating the integration, I think we should make a stop for deep diving into the connector configuration to illustrate how traditional information systems meet large language models (LLM).
WebMethods Webmethods.io: Implementation If you follow my Webmethods.io Integration series, you already have an environment, the process blueprint, custom action, and the X/Twitter connector. It's time to use them in a new integration flow.
WebMethods X.com: Webmethods Custom Connector The main reason I started this automation project was X integration. The changes in the social network API were an excuse for many automation tools to move X integration to premium plans. Webmethods.io offers code-free integration, and here is a recipe.
WebMethods Webmethods.io: Workflow Design By now, you are familiar with the Webmethods.io Integration, get access to your forever-free environment, and create your first project. It's time to draw.
Ansible Ansible: A Shell Execution Shortcut Here is a small trick that could make your playbooks, if not more readable, at least shorter. The trick is useful if you use Shell to execute multiple commands on targets.
Integration Webmethods.io Integration In my previous post, I went through why I chose Software AG and WEBMETHODS.io Integration. Today, I want to walk you through the registration and account creation process.
Docker Multiplatform Images: Customization In the previous post, I built a simple multiplatform container image. Now, we discuss how to customize the image contents depending on the target architecture.
Docker Multiplatform Images: Practical Guide Have you ever wondered how Docker knows which image layer is required to run a container in your operating system? The answer is multiplatform images; this piece walks you through the build process.
Registry Oracle Container Registry Tips Oracle offers Container Registry, a large set of containerized Oracle licensed and open-source products. Unfortunately, this product is not the most user-friendly, and instructions on third-party sites do not improve the situation.
OCI Featured OCI Function Deployment Error Oracle Cloud Infrastructure offers serverless functions. For OCI, function development requires tools to create and deploy code in accordance. This set of independent tools often results in mysterious errors.
Security Python: Testing Secure Connections Security control validation and enforcement are tasks we have regularly. We have created a small Python application that simplifies socket tests
Git Git: From SSH to Personal Access Tokens Accessing remote repositories over SSH is a convenient, reliable, and secure way to sync your local and remote repositories. However, architectural changes and security requirements encourage moving from SSH to HTTPS/TLS protocols.
GCP Ghost: Create an Instance Group Since the beginning of the quest, we have had cloud-based site backups, Google Cloud architecture for a low-maintenance and inexpensive test site, plus a working instance template. Now let's ensure instance availability and security.
Google Ghost: Building an Instance I publish journal notes of my cost-effective blog engineering challenge. This time I'll walk you through the cornerstone of my design - compute instance. Bear with me for a few more minutes, and I'll walk you through the chain of decision points to the final solution.
GCP Ghost: Architecting a Test Site My previous topic described preparation steps for my new pet project - a test site in the Google Cloud. This post describes the design stage with my train of thought explanation and the current design state. Let's start with the requirements reiteration and then review the design steps.
Database Oracle Database: Zoning Conundrum The Oracle Database has long and complicated relations with time-aware data. It has gotten even more interesting in the internet era and global data processing. As usual, it's a story about how a single line of code at the design time could save many work hours in maintenance.
OCI OCI: Secure Load Balancer It started as a routine wildcard certificate renewal and updating on the Oracle Cloud Infrastructure. It usually takes about 20 minutes, but not today when the certbot offered me a private key update.
Bash A Shell Tricks: Session Color Coding The best way to understand what server you deal with is color-coded command line prompts. Different Shell interpreters and different terminals offer different commands and capabilities, but modern server-side world is extremely Linux centric, where the BASH dominates the market.
