Create secrets to use with your elastic stack to create keystore in kubernetes – minio example – helm example included

Posted on by jlim0930

For this example I will stand up a very simple minio server on my localhost. Create kubernetes secrets for the s3.client.default.access_key and s3.client.default.secret_key. Configure my elasticsearch pod with initContainer to install the repository-s3 plugin and secureSettings to create the keystore. minio server This is a very simple, not secure setup just for testing $ mkdir data $ wget https://dl.min.io/server/minio/release/linux-amd64/minio $ chmod +x minio $ ./minio server ./data API: http://192.168.1.251:9000 http://172.17.0.1:9000 http://192.168.122.1:9000 http://192.168.49.1:9000 http://127.0.0.1:9000 RootUser: minioadmin RootPass: minioadmin Console: http://192.168.1.251:36012 http://172.17.0.1:36012 http://192.168.122.1:36012 http://192.168.49.1:36012 http://127.0.0.1:36012 RootUser: minioadmin RootPass: minioadmin Command-line: https://docs.min.io/docs/minio-client-quickstart-guide $ mc alias set myminio http://192.168.1.251:9000 minioadmin minioadmin Instead of getting… Continue Reading →

Helm charts to install the Elastic Stack using minikube

Posted on by jlim0930

On the previous post we used the minikube wrapper kube.sh to install ECK – Elastic Cloud on Kubernetes. ECK uses an operator that was created by Elastic to deploy and orchestrate the Elastic Stack in kubernetes. ECK is not the only way to install elasticsearch in kubernetes, you can also use Helm charts to install the Stack. What is the difference between an operator and helm charts? Helm Helm is a package management system for kubernetes. The packaging format is called charts. In OS terms its like rpm or deb packages. An application is packed into a package that can… Continue Reading →

Elastic Cloud on kubernetes (ECK) on minikube

Posted on by jlim0930

ECK is Elastic cloud on kubernetes – Kubernetes Operator pattern that extends basic kubernetes orchestration to easily deploy, secure, upgrade Elasticsearch and the rest of the stack such as kibana, logstash, various beats, and much more. In my previous article I wrote about my kube.sh script which is a wrapper that installs a minikube environment to run your kubernetes projects. We will use the wrapper to deploy our kubernetes environment and start deploying elasticsearch using ECK. The steps below are not limited to my minikube wrapper script but you can follow the same process for any kubernetes environment. Lets get… Continue Reading →
