Description W. Trevor King 2019-07-29 22:34:57 UTC
Description of problem:

Currently setting 'encrypted: true' in a volume definition is silently ignored.

Version-Release number of selected component (if applicable):

Currently the encrypted setting [1] from [2] is ignored by the AWS cluster-API provider:

$ git grep Encrypted | grep -v vendor/
pkg/apis/awsproviderconfig/v1alpha1/awsmachineproviderconfig_types.go:    // Indicates whether the EBS volume is encrypted. Encrypted Amazon EBS volumes
pkg/apis/awsproviderconfig/v1alpha1/awsmachineproviderconfig_types.go:    Encrypted *bool `json:"encrypted,omitempty"`
pkg/apis/awsproviderconfig/v1alpha1/zz_generated.deepcopy.go:    if in.Encrypted != nil {
pkg/apis/awsproviderconfig/v1alpha1/zz_generated.deepcopy.go:        in, out := &in.Encrypted, &out.Encrypted

This means that you cannot use the setting to get encrypted root volumes for compute machines [3].  The provider should respect the setting and provision encrypted volumes when requested.

clusterversion: 4.2.0-0.nightly-2019-08-05-223032

Create a machine setting "encrypted: true", check EBS volumes, could see "Encryption: Encrypted"
