Kubernetes Core Components and Terminologies

Kubernetes Core Components and Terminologies Kubernetes, as a robust container orchestration platform, offers a rich ecosystem of components to simplify application deployment and management. Below is an expanded overview of the most important Kubernetes terminologies, providing deeper insights into their functionality. 1. Job: Managing Batch Workloads A Job in Kubernetes ensures that a specified number of Pods execute tasks to completion. Once the tasks are completed, the Pods terminate, making Jobs ideal for one-time or batch processing tasks. Key Use Cases : Data processing pipelines. Database migrations. Sending automated emails or notifications. Advanced Features : Parallel Jobs : Distribute tasks across multiple Pods for faster execution. Completion Policies : Define when a Job is considered successfully completed. 2. Namespace: Segregating Resources Namespaces are logical partitions within a Kubernetes cluster, designed to isolate resources among different teams, projects, or e...

Automation Script (Action Launch Point) - Extracting 16-Digit Numbers with Specific Patterns

Automation Script - Extracting 16-Digit Numbers with Specific Patterns Set the escalation to read the script. The script takes input from the Long Description, finds the 16-digit numbers from that string with the mentioned pattern, and then sets those numbers to the Summary (in the SR application) Step 1: Create script with action launch point having two variables (IN, OUT).          Script Code       --------------       # Find 16 Digit numbers from Long Description and Set all 16 Digit Numbers in Summary           from java.lang import Runtime from java.util.regex import Matcher from java.util.regex import Pattern descript='' longdesc1='' # Find the patterns of 16 Digit numbers from String and Set that 16 digit numbers into summary pp1 = Pattern.compile("((\d{4})-(\d{4})-(\d{4})-(\d{4}))|((\d{4}) (\d{4}) (\d{4}) (\d{4}))|(\\b\\d{16}\\b)" ) m1= pp1.matcher(longdesc) while(m1.find()):  longdesc1=...

Integrating IoT Platform with Maximo Meters - Use Case

IOT Platform with Maximo Meters We will use a simulated temperature sensor to send temperature reading, simulated gauge meters in Maximo, to the IoT QuickStart.  The device reading (message) will then be sent to NODERED, which will parse the message into a RESTAPI call that will insert the meter reading into the referenced Asset.  The reading will update the measure point and trigger a work order using Maximo’s inherent functionality. Key Concepts Quick and easy demonstration of connecting a device and viewing of reading. Use of NODERED. Use of the Maximo RESTAPI. Connected products interaction.    Using Maximo’s inherent functionality for work order generation from Condition Monitoring. Requirements: Bluemix Account with an instance of IoT Platform Starter Kit deployed. Instance of Maximo without firewall. Note: Please send an email to kayala.ramakrishna@gmail.com to get the detailed steps document.
