![]() Go to your domain actions and select the Upgrade Domain button. Reindexĭocker run -it -env-file vars.env dnxsolutions/es-auto-upgrade reindex.py This next steps will repeat until you get to the latest ES version. Amazon ES 7.x domains retain the previous default of five. For new indices, self-hosted Elasticsearch 7.x has a default shard count of one. As a result, certain APIs no longer require a mapping type in the request body (such as the _bulk API). Like Elasticsearch 6.x, indices can only contain one mapping type, but that type must now be named _doc. Before initiating an in-place upgrade, we recommend taking a manual snapshot of the 6.8 domain, restoring it on a test 7.x domain, and using that test domain to identify potential upgrade issues. Important: Elasticsearch 7.0 includes numerous breaking changes. To minimize downtime during the upgrade from Elasticsearch 5.6 to 6.x, Amazon ES reindexes the .kibana index to .kibana-6, deletes .kibana, creates an alias named .kibana, and maps the new index to the new alias. Check that your client code creates only a single mapping type per index. Indices created in version 5.x still support multiple mapping types when restored into a 6.x cluster. Important: Indices created in version 6.x no longer support multiple mapping types. From 5.1 to 7.4įrom now on Amazon ES offers in-place Elasticsearch upgrades for domains that run versions 5.1 and later and we can proceed using the In-place along with the Elasticsearch reindex API to get to version 7.4.Ĭurrently, Amazon ES supports the following upgrade paths. When the script finishes running, you should have your brand new ES domain at version 5.1 with all your data from 2.3. # Download the required variables, you should edit this file.ĭocker run -it -env-file vars.env dnxsolutions/es-auto-upgrade upgrade.py Delete IAMpermissions (Policy, Role, and detachments).Restore snapshot from S3 into the new domain.Take snapshot from 2.3 and save it to S3 bucket.Create IAMpermissions (Policy, Role, and attachments).Create new Elasticsearch domain (Optional).Create an S3 bucket to store snapshot from 2.3 domain.Focused on avoiding problems with your root domain, this script will create a brand new domain and execute all the steps in there.Īll the code can be found at: es-auto-upgrade Script steps To save your time, we have created a python script that communicates with the AWS API and setup everything for us. So to successfully upgrade, you will need to create an S3 bucket and a set of permissions that allow your ES domains to dump data into the bucket. Pre-requirementsĪccording to the AWS documentation, the first upgrade needs to be done manually using the ES snapshot API. The idea of this post is to show the problems that you can face during this process of upgrading and also give you a more simplified way than following the AWS documentation. After a while, you realize that it’s five major releases behind the stable version and there’s no straight path to upgrade. Sometimes it is common just to deploy a Elasticsearch domain at AWS and forget to keep it up-to-date with the latest version.
