2021 Release

This release is simply updating the pre-existing template to support the latest publicly available versions of CM/CDH7 along with OCI OS images for OEL 7.7.

Defaulting to 7.4.4 for CM because the repodata links for 7.5.1 are giving a 404 (https://archive.cloudera.com/cm7/7.5.1/redhat7/)

Final TF v0.11 Release

This will act as an archive release for ORM TF v0.11. Moving forward the ORM TF v0.12 template will be the primary template.

Resource Manager Compliant Release

This release is for use with OCI Resource Manager. Some bits had to be re-worked from the main branch to allow this functionality to work. The long term goal is to merge this into master with methodology which will allow both Resource Manager and stand-alone Terraform to both work, but for now this release will provide a path forward using Resource Manager.

The benefits to using Resource Manager are simplification of deployment (no need to install Terraform prerequisites), and deployment state is stored in the Tenancy allowing for shared management of the infrastructure.

"Simple" Release

This release marks a major change to how Cloudera Enterprise Data Hub deployment is performed on OCI using Terraform. All post-deployment tasks are now "hands off", meaning a combination of user_data (CloudInit) and extended_metadata are leveraged to automate Cluster setup. The Utility host now runs all Cluster deployment tasks, which are logged to /var/log/cloudera-OCI-initialize.log.

As part of the "simple" enhancement, Cluster Security (Kerberos) and High Availability are turned off by default. This was done to simplify the deployment, improve deployment speed, and improve usability for end users who are not familiar with Kerberos Principals as they relate to Hadoop operation.

It is highly recommended that these features are enabled for any production deployment, or if any sensitive data is being used. This is detailed in the top level README in the Kerberos section.

v2 Final Release

This will mark the final release of v2 deployment methodology. Moving forward, deployment will be completely "hands-off", integrated into CloudInit rather than manual execution which runs externally against Cloudera Manager API.

CDH v6 - Modules & Object Storage

This release reflects an improvement to the Terraform layout - a modularization that will become especially useful with Terraform v0.12.

Also included is automation to enable Object Storage connectivity via S3 Compatibility as part of the deployment.

CDH v6 Release

This release represents v6 only deployment using Cloudera Manager v6.1 and Python cm_client.

This release includes Secure Cluster by default using local KDC installed on the Cloudera Manager Utility host.

CDH v5 Release

This 1.0.0 release will mark the end of development to CDH v5 Terraform modules using deprecated cm_api v19.

Moving forward support for v5 clusters will be back-ported using the v6 automation and cm_client.
