You back up AWS environment activation parameters using the Cloudera Data Warehouse UI , AWS CLI, and kubectl.
AWS environment activation settings that need
to be available in the new environment may include IP-CIDRs for the Kubernetes cluster
and load balancer, the deployment mode setting, reduced permissions mode, and overlay
networks. It is required that you gather and document these settings to have the
environment behave the same after the back-up/restore process as before. The activation
parameter values are available in the Cloudera Data Warehouse UI.
Additionally, some parameters may be fetched using AWS CLI and kubectl.
The following
steps gather and document the environment parameters.
Deployment Mode (Network selection)
Get subnet information in one of the following ways:
Use the Cloudera Data Warehouse UI
Navigate to Environment Details > General Details, and note the settings for Public
Subnets or Private
Subnets.
In the Cloudera Data Warehouse UI, navigate to Environment Details > Configurations, and note the settings of Enable IP-CIDR for
Kubernetes cluster and Enable IP-CIDR for the load
balancer.
Overprovision nodes
Document the value of Overprovision nodes.
Stored behind the CDW_CLUSTER_OVERPROVISIONER entitlement.
Use Custom ECR repository
Document the value of Use Custom ECR repository.
Stored behind the CDP_CUSTOM_REPO entitlement.
Use Overlay Network
Using kubectl, get the value of Use Overlay Network.
Using the Cloudera Data Warehouse UI, determine whether or not
your current policy has standard activation permission.
If the current policy does not have the standard activation permission, when
you reactivate the environment you see a
prompt to use the Reduced Permissions Mode.
In Reduced
Permissions Mode, you deploy the cluster manually. A Cloudformation template
is generated and the you must deploy the cluster and apply some role-based
access control roles to the Kubernetes cluster.
Enable CloudWatch logs
Using the Cloudera Data Warehouse UI, navigate to Environment Details > Configurations > Enable CloudWatch Logs to get the value of Enable CloudWatch
logs..
CloudWatch logs provide better visibility into cluster operations in addition
to the diagnostic bundles within Cloudera Data Warehouse. Enabling
this option will not impact the restore procedure, even if it was not previously
configured in the old environment.
Additional External Buckets
Using the Cloudera Data Warehouse UI, gather values of the
Additional External Buckets parameter. Navigate to Environment Details > Configurations > Bucket Name.
