Kubernetes Setup

This guide will walk you through setting up a small Germain UX environment, suitable for testing purposes. Please note that this configuration is not recommended for production environments.

Hardware Requirements for the Kubernetes Cluster:

• CPU with at least 2 cores

• 4 GB of RAM

• 20 GB of disk space

• 8 Minimum Node Group Size

• 16 Maximum Node Group Size

• 8 Desired Node Group Size

• GP3 Node Volume Type

Note: The cluster size mentioned here is based on the availability of our lab environments and serves as a sample use case. Feel free to adjust your cluster size based on the availability of memory and CPU per node.

Software Requirements

Kubernetes Cluster

Installation

1. Download and extract the Germain UX package

   CODE

   wget < Public URL to be Finalized >
   tar xzf germainux-kubernetes-2023.4-binary.tar.gz

2. Deploy your license key

   CODE

   Update your license details inside the below file
   File Name: germain.apm.monitoringConfig.systemConfig.license.json
   File Path: <EXTRACTED_FILES>/templates/config/license/
   
   Update the encrypted value in the license file with your license file text content.

   

3. Configure cluster settings in deploy-germain.sh file as per requirement. Recommended settings for a small cluster is as below.

   CODE

   elasticSearchVersion="8.8.1"
   mysqlVersion="8"
   kibanaVersion="8.8.1"
   activeMqVersion="5.18.3"
   zookeeperVersion="3.6.3"
   hazelcastVersion="5.2.2-SNAPSHOT"
   kafkaVersion="3.4"
   germainVersion=2023.3
   germainApmBuildRegistry=public.ecr.aws/h0m9e4y5
   germainEnvName=germain-demo

4. If you are planning to use an external database for config store, you need to modify the below two parameters and set the mysqlReplicase to 0. (optional)

   CODE

   germainDbHostname="test-db"
   germainEnvName=germain-qa

   Make sure you update the common.properties file with proper DB details for config store

   CODE

   germain.config.url=jdbc:mysql://germainapm-mysql:3306/APMCFG?rewriteBatchedStatements=true
   germain.config.username=APMCFG
   germain.config.password=APMCFG

5. Update email settings (optional)
   Update the email settings in the included common.properties file to match your SMTP server:

   

6. Make sure your kubectl command is configured to run kubernetes commands.

   CODE

   kubectl get nodes

7. Start your cluster deployments running deploy-germain.sh
   Note: This will create the kubernetes yaml files inside your germainEnvName folder and you can re-use them in any of your kubernetes clusters with kubecl apply commands. Make sure you apply them in below order.

   CODE

   1) configmap folder
   2) infra folder
   3) germain folder

8. At the end of your command output, you will get the url to connect to the Germain UX Workspace.
   By default, the workspace can be accessed on port 8080 using the default credentials (admin / admin):
   ex: http://<your final url>:8080/germainapm/workspace/
