Get started with IBM Cloud – a student perspective

Leave a comment

In this new blog post I want to address a common situation I see students facing: there are several cloud providers and you want to check out the different platforms. The reason is you want to be prepared; for example working with cloud resources related to courses at your university or for a hackathon. One of these cloud providers is IBM Cloud and this blog post is about how to get started with IBM Cloud. This is a tailored version of my blog post: How to prepare for a Hackathon with IBM Cloud for you as a student.

IBM Cloud provides a wide range and huge amount of different services, runtimes, and more. It covers both virtual and hardware –based servers on one demand cloud-platform, which means you have complete infrastructure control. One of the great things about IBM Cloud is that you can register for an account and try before you buy without needing a credit card.

From my point of view, one of the most important objectives for student is to have a running application instance live.

To do this you need a runtime 😉

Getting started with continuous integration and delivery (CI/CD) using Tekton and an Open Toolchain on IBM Cloud (Part 3/3)

2 Comments

This blog post is about the last 14 min video for my YouTube playlist related to the hands-on tutorial “Develop a Kubernetes app by using Tekton delivery pipelines“. In this video we do the final setup of the toolchain and then we execute a Tekton pipeline. For more background please visit my first blog post “Getting started with continuous integration and delivery (CI/CD) using Tekton and an Open Toolchain on IBM Cloud (Part 1/3)“.

Note: The video was live recorded and it would take 30 min for the entire session, but I did reduce the time of the video to only 14 min ;-).

But now the video could be sometimes a little bit (too) fast.

This blog post is about my newly created 9 min YouTube video about the setup of the prerequisites for the hands-on tutorial “Develop a Kubernetes app by using Tekton delivery pipelines“. That video is a part of the video series for the tutorial. For more details please visit my last blog post “Getting started with continuous integration and delivery (CI/CD) using Tekton and an Open Toolchain on IBM Cloud (Part 1/3)“

Getting started with continuous integration and delivery (CI/CD) using Tekton and an Open Toolchain on IBM Cloud (Part 1/3)

In this blog post I want to highlight that I created a 10 min detailed overview YouTube video, which is the first video of a video series related to the hands-on tutorial “Develop a Kubernetes app by using Tekton delivery pipelines“. In that tutorial video series, we setup an easy consumable Tekton pipeline in a toolchain using developer tools for think, code and deploy in context of continuous delivery. We deploy a containerized web application to a free Kubernetes Cluster on IBM Cloud.

Run a PostgreSQL container as a non-root user in OpenShift

Leave a comment

In this blog post I want to point out a simple topic: How to run a simple PostgreSQL Docker image as a non-productive container in OpenShift? As you maybe know, OpenShift doesn’t allow by default to run container images as root.

The image below shows the result of the simply deployed postgreSQL image from dockerhub.

postgres openshift root user ibmcloud

It’s possible to enable images to run as root on OpenShift, that’s documented in the OpenShift documentation here, by adding a service account.

But, in this blog post we choose an alternative way, where we don’t change the security in OpenShift, here we will customize the postgreSQL Docker image a bit. We will follow the steps to create a postgreSQL database on OpenShift, along the creation of the database called postgreSQL database-articles for the Cloud Native Starter reactive example .

These are the major steps:

  1. Write the specifications and configurations  for:
    1. … the Dockerfile
    2. … the  yaml with a Kubernetes Deployment and a Kubernetes Service specification. 
  2. Execute the oc CLI commands to:
    1. … create a OpenShift project
    2. … create a OpenShift build configuration
    3. … start the build
    4. … apply the Deployment and Service specification
    5. … expose the Service

Setup a MongoDB in less than 4 min on a free IBM Cloud Kubernetes cluster at a Hackathon

Leave a comment

In this blog post I want to highlight that I just created a GitHub project and a 10 min YouTube video to “How to setup mongoDB in less than 4 min on a free IBM Cloud Kubernetes cluster at a Hackathon”.

My objective is to provide a small guide, how to setup a MongoDB server and Mongo UI (Mongo-Express)  on a free IBM Cloud Kubernetes cluster and when you don’t want to use the existing MongoDB service on IBM Cloud.

On the free IBM Cloud Kubernetes cluster:  No persistent volume claims are used. So, keep in mind, if your Pod in Kubernetes crashes the data of the database is lost.

Based on the “security feature” of the MongoDB default port 27017, you need to run the application to access the MongoDB server in the Kubernetes cluster .

In other words, your UI application has to access the database with a server application, which also runs on the free Kubernetes cluster (like the Mongo UI (Mongo-Express)  in that example here). You should implement a backend for frontend architecture.

The YouTube video shows the setup and a description how it works.

Invoke reactive Endpoints with Quarkus and MicroProfile

Leave a comment

In this blog post I want to point out that I just created a 15 min YouTube video related to the great Hands-on workshop: Reactive Endpoints with Quarkus on OpenShift. In this video you can watch and follow the steps of the exercise 3 “Invoke Endpoints reactively”. Niklas wrote a great blog post about the topic of that exercise. This is the name and link of his blog post Invoking REST APIs asynchronously with Quarkus.
