In this post I am going to share my experience for running the docker image of wso2 apim analytics dashboard that caused some issue while running it. Below is the summary of the same- Environment: Windows, RHEL 8.3, WSO2 Analytics 3.2.0 Problem: While executing docker run command, it gives following error- sudo docker run wso2am-analytics-dashboard:3.2.0.20 : not foundarbon/docker-entrypoint.sh: 17: /home/wso2carbon/docker-entrypoint.sh: 18: set: Illegal option - Cause:  The problem occurred due to dos2unix conversion issue. Basically the file docker-entrypoint.sh was created in a winodws machine in notepad++ utility but remained with EOL conversion as Windows (CR LF). Further this file was uploaded to a linux machine where actual execution has to be done. Solution We need to change the EOL conversion of the file ( docker-entrypoint.sh ) to Linux (LR) prior to docker image creation. I have used windows environment and notepad++ utility to do the same as- 1. Open the file doc...

WSO2 Products Docker Image Customization I have got a use case where I have to do the containerized deployment of WSO2 APIM & Analytics (v3.2.0) on OpenShift. Also, there was a requirement to customize the docker image prior to the deployment on OpenShift. Below are the steps I used to deploy the customized docker image of apim & analytics (dashboard+worker) on OpenShift Cluster- 1. Download the apim, analytics base pack (3.2.0) from official WSO2 WebSite 2. For APIM/Analytics extract the zip package 3. Navigate to $PRODUCT_HOME/bin 4. Locate the file wso2update_linux and make sure file has execute permission or do [chmod +x wso2update_linux] 5. Execute the file ./wso2update_linux [below snippets are for in-place updates for analytics, same applies to apim as well] --------------------------------------------------------------------------------------------- [kumar@dev001 bin]$ ./wso2update_linux Initializing updates with credentials Please press 'enter' to c...

A Developer with access to his/her GitHub account Developer develops an app and pushes the code to GitHub (a distributed version source code control utility) 2. Jenkins setup Jenkins setup is required for DevOps viz. creating CI/CD pipeline/ Web Hooks. For current environment, Jenkins server is running on Google Cloud platform. 3. Dockerhub account A valid dockerhub account is required for container image registery. 4. A Kubernetes(k8s) Cluster (GKE) A k8s cluster is required for running the containers /container orchestration, scaling and overall container lifecycle management. I have used Google Kubernetes Engine (GKE) @ Google Cloud. It contains 1 load balancer and 3 nodes. Conditions K8s cluster, Jenkins, GitHub should be on  the same network (if private...
