As pointed out in the initial code review of #4351, some of the steps
from the standard EBS builder were (intetionally) omitted. It turns out
that these actually are useful, and the original rationale for the
omission was wrong. Consequently, this commit adds in the following
steps:
- `StepPrevalidate`
- `StepTagEBSVolumes`
- `StepDeregisterAMI`
- `StepCreateEncryptedAMICopy`
- `StepAMIRegionCopy`
- `StepModifyAMIAttribute`
- `StepCreateTags`
We also fix the interpolation filter and documentation to reflect these
additions, though the majority were already documented and just not
functional.
This commit removes the root volume from the list of launch block device
mappings passed to the image, since it is already passed in the form of
a snapshot (which is then configured to be the root device). Without
this commit, AMIs created using this builder have two root volumes
attached on launch.
Set SriovNetSupport to "simple". As of February 2017, this applies to C3, C4,
D2, I2, R3, and M4 (excluding m4.16xlarge).
Set EnaSupport to true. As of February 2017, this applies to C5, I3, P2, R4,
X1, and m4.16xlarge.
This commit adds a new type of builder which builds an AMI based on a
snapshot of an EBS volume which is provisioned on a "surrogate"
instance. This can be used to build operating system images from
scratch, but unlike the `chroot` builder does not require running from
an AWS EC2 instance.
