INSTALLING APACHE CAMEL-K ON IBM KUBERNETES SERVICE (IKS)
This Document is built with the collaboration Juan José Pérez B
Introduction
In this tutorial we are going to install the Apache Camel-k over an IKS (IBM CLOUD Kubernetes Service) the commands used here to deploy the infraestructure are Linux
What is Camel-k?
Apache Camel K is a lightweight an integration framework built from Apache Camel that runs natively on Kubernetes and is specifically designed for serverless and microservice architectures.
Users of Camel K can instantly run integration code written in Camel DSL on their preferred cloud (Kubernetes or OpenShift).
Prerequisites
Tools are already installed
kubectl: Kubernetes Command Line Tool
Helm (Optional): Package management for Kubernetes
How to create a Free Account on IBM Cloud
For this step, you can refer to the official link of IBM Cloud above
You need to upgrade your account to receive USD$200 in order to create the basic Kubernetes cluster.
Install IBM Cloud Command Line Tool
Use the steps on this page to install the latest IBM Cloud CLI based on your OS:
In our case we are going to install with:
curl -fsSL https://clis.cloud.ibm.com/install/linux |sh
If you need install on Windows you need download the installer from here
Create a Kubernetes Cluster
After to create your account, you need log in to this page https://cloud.ibm.com/login and put your credentials first
When you login, you click in the top left menu and select the option kubernetes > clusters
Now you can see the next screen and you can select the option create cluster
In select a plan you can choose the option free and select the name for your cluster and click in create to build the cluster
Finally, after 10 minutes approximately the cluster is Ok
Accessing your cluster
- Log in to your IBM Cloud account. Include the — sso option if you have a federated ID.
ibmcloud login
2. Set the Kubernetes context to your cluster for this terminal session.
ibmcloud ks cluster config --cluster cluster1
3. Verify that you can connect to your cluster.
kubectl config current-context
Now, you can run kubectl commands to manage your cluster workloads in IBM Cloud
Create container Image Registry
Create the container registry in order to use in the next steps.
ibmcloud cr namespace-add camel-registry
Download and Install Camel-k Cli
Download and uncompress the last release of camel-k command line tool. It contains a small binary file named kamel that you should put into your system path. in Linux, you can put kamel in /usr/bin.
Install Camel-k
There are two ways to install Camel-k using the kamel emmbeded installation or helm hub
NOTE: You need to follow only one of the following procedures
Procedure 1.
Install Camel-k Cli on the cluster
kamel install --olm=false --maven-repository=https://repository.apache.org/content/repositories/snapshots@id=apache-snapshopt@snapshots --registry='us.icr.io/camel-registry' --wait
Procedure 2.
Install Camel-K with helm
helm repo add camel-k https://apache.github.io/camel-k/charts
helm instal --generate-name --set platform.cluster=kubernetes camel-k/camel-k
Check the Installation
Create a Camel-k file Dummy integration
vim hello.groovy
from(‘timer:tick?period=3000’)
.setBody().constant(‘Hello world from Camel K’)
.to(‘log:info’)
Execute the command:
kamel run hello.groove
Check the Camel integration
To check the created integration put the command:
kamel get
A new Pod will be spin up
Uninstall Camel K
