海外TECH	DEV Community	How to migrate Apache Solr from the existing cluster to Amazon EKS	https://dev.to/haintkit/how-to-migrate-apache-solr-from-the-existing-cluster-to-amazon-eks-3b3l	How to migrate Apache Solr from the existing cluster to Amazon EKSCo author coanghaSolr is an open source enterprise search platform written in Java Its major features include full text search hit highlighting faceted search real time indexing dynamic clustering database integration NoSQL features and rich document e g Word PDF handling Providing distributed search and index replication Solr is designed for scalability and fault tolerance Solr is widely used for enterprise search and analytics use cases and has an active development community and regular releases Solr runs as a standalone full text search server It uses the Lucene Java search library at its core for full text indexing and search and has REST like HTTP XML and JSON APIs that make it usable from most popular programming languages Solr s external configuration allows it to be tailored to many types of applications without Java coding and it has a plugin architecture to support more advanced customization In this article I ll walk through the process of migrate Solr from a Kubernetes cluster to Amazon EKS Elastic Kubernetes Service using backup and restore method Please take into account depend on your Solr s version system requirement circumstance etc you will need to extra setup on EFS to ensure your Ks cluster is able to access to network file system on AWS This will not be required if your Solr s version can use S as backup repository Please refer to the links below Solr Operator documentationWorking with Amazon EFS access points EFSIs it possible to make EFS publicly accessible For the purpose of demonstrating I ll migrate Solr from an EKS cluster to another one within the same region However you can apply this migration method to any Kubernetes cluster running on any platform Prerequisite Before you begin make sure you have the following available AWS account and required permission to create resourcesTerraform or AWS CLI kubectl and helm installed on your machineThe following step is what we will do in this article Step Create target EKS cluster Step Install Solr using Helm Step Setup Solr backup storage Step Create backup from origin cluster Step Restore Solr to EKS using backup Let s go in details Create target EKS clusterThere are many ways to create a cluster such as using eksctl In my case I will use terraform module cause it s easy to reuse and comprehend This is my Terraform code template to create the cluster You can just copy and run it or customize based on your desired configurations provider aws region ap southeast default tags tags environment Dev provider

vpc cni coredns kube proxy You can check AWS resources in AWS management console Install Solr using helmNext step is to install Solr using helm Install the Solr amp Zookeeper CRDshelm repo add apache solr helm repo update Install the Solr operator and Zookeeper Operatorkubectl create f version gt all with dependencies yamlhelm install solr operator apache solr solr operator version lt version gt Install the Solr zookeeperhelm install solr apache solr solr n solr version lt version gt Replace version with your chart version or chart version which contain your Solr s version Next run this command to get admin s password and access to Solr UI Get solr passwordkubectl get secret solrcloud security bootstrap n solr o jsonpath data admin base decode Port forward Solr UIkubectl port forward service solrcloud common n solrNow open your browser and type http localhost the result should be Then using the admin s password we get above to login Setup Solr backup storageAfter you have Solr installation done it is time to setup Solr backup storage At the time of writing this post AWS supports backup storage types EFS and S Depending on your Solr s version and system requirement you can choose either of them In this demo I ll use EFS as backup storage since this storage type is compatible to most Solr s version For more information please visit this link To setup EFS as Solr s backup storage you need to create an EFS in AWS This terraform code template will create EFS resource module efs source terraform aws modules efs aws version File system name solr backup storage performance

subnet cidr blocks module vpc private subnets Replace EFS id with EFS resource ID e g fs abcdef you just created in previous step and then run command kubectl apply f solr efs pvc yaml n solrFrom now on EFS is ready to use on your cluster In next step you need to upgrade Solr to take EFS as backup storage First create values yaml file as below backupRepositories name solr backup volume source Required persistentVolumeClaim claimName solr efs claim directory solr backup OptionalNote that you will need to do this for both origin and target cluster Second you need to roll it out using helm run command helm upgrade install solr f values yaml apache solr solr n solr version lt version gt Finally you should see EFS claim name in your Solr pod using this command as an expected result kubeclt describe statefulset dica solrcloud n solr grep solr efs claim ClaimName solr efs claimCreate backup from source clusterIn order to restore Solr to new cluster you definitely need to have a backup file in your hand You are going to backup a collection using Solr API by using the following command curl user admin lt password gt https lt origin solr endpoint gt solr admin collections action BACKUP amp name lt backup name gt amp collection lt collection name gt amp location file var solr data backup restore solr backup amp repository solr backupIf you have more than one collection just repeat the process Replace password with admin s password origin solr endpoint for your origin Solr s endpoint and as your choice You can check your backup progress by accessing to a pod and then check the directory Restore Solr to target EKS clusterSince both origin and target Solr s backup storage are using the same directory in AWS EFS as you setup in previous steps You only need to invoke the restore API in your target cluster curl user admin lt password gt http localhost solr admin collections action RESTORE amp name lt backup name gt amp location var solr data backup restore solr backup amp collection lt collection name gt As I configured to use port fowarding I only need to replace Solr s endpoint with localhost Finally let s go to Solr UI and you should see the collection have been restored successfully to your new EKS cluster After that you can start setting up autoscaling ingress security and other resources for Solr in new EKS cluster and connecting your application to the database Should you need any further information regarding Solr s backup and restore API please visit this link ConclusionSolr is widely used in enterprise and SMB Depending on your system requirements and circumstances migrating Solr to Amazon EKS will require different setup and approaches I hope this post will provide you with useful information about Solr migration using backup and restore Any comments are welcomed Thank you for your reading Thanks co author coangha for your effort in this post	2023-08-31 03:24:37
