We're pleased to announce that Bitbucket DC Helm chart v1.20 onwards comes with an optional OpenSearch sub-chart.
When opensearch.install is enabled in your Helm values file, the Bitbucket Helm chart will install OpenSearch with the default settings:
Bitbucket will be automatically configured to use the deployed OpenSearch cluster for search.
You will find example configurations and how-tos (create custom users, configure SSL etc) in the official documentation.
This configuration is also supported in release 2.9.0 of the Data Center Terraform.
Feel free to give it a go and do not hesitate to reach out if you have questions or comments.
