This commit adds some basic tests for block device functionality. It also
expands the existing block device documentation as well references the
new "volume attach" resources for further block storage functionality.
This commit is changing the `volumes` block from being computed to non-computed.
This change makes the Terraform configuration the source of truth about volumes
attached to the instance and therefore is able to correctly detect when a user
detaches a volume during an update.
One thing to be aware of is that if a user attached a volume out of band of an
instance controlled by Terraform, that volume will be detached upon the next
apply. The best thing to do is add a `volume` entry in the instance's
configuration of any volumes that were attached out of band.
This commit also explicitly detaches volumes from an instance before the
instance terminates. Most Block Storage volume drivers account for this
scenario internally, but there are a few that don't. This change is to support
those that don't.
In addition, when volumes are read by the instance, volumes configured in the
Terraform configuration are the source of truth. Previously, a call was being
made to OpenStack to provide the list of attached volumes.
It also adds a few new tests and fixes existing tests for various volume
attach-related scenarios.
When applying or removing 2+ security groups from an instance, an EOF
error will be triggered even though the action was successful. This
patch accounts for and ignores the EOF error. It also adds a test
case.
Security Group and Port documentation are also updated in this
commit.
This commit fixes and cleans up instance block_device configuration.
Reverts #5354 in that `volume_size` is only required in certain
block_device configuration combinations. Therefore, the actual
attribute must be set to Optional and later checks done.
Doc upates, too.
This commit adds the ability to create instances with multiple
ephemeral disks. The ephemeral disks will appear as local block
devices to the instance.
This commit adds the ability to associate a Floating IP to a specific
network. Previously, there only existed a top-level floating IP
attribute which was automatically associated with either the first
defined network or the default network (when no network block was
used).
Now floating IPs can be associated with networks beyond the first
defined network as well as each network being able to have their own
floating IP.
Specifying the floating IP by using the top-level floating_ip
attribute and the per-network floating IP attribute is not possible.
Additionally, an `access_network` attribute has been added in order
to easily specify which network should be used for provisioning.
This change better reflects how block devices are passed to the Nova API
and allows for future enablement of block_device features. It also resolves
an interpolation bug.
This commit cleans up the volume and block device handling in the instance
resource. It also adds more acceptance tests to deal with different workflows
of attaching and detaching a volume through the instance's lifecycle.
No new functionality has been added.
This commit fixes the previously broken "boot from volume" feature. It also
adds an acceptance test to ensure the feature continues to work.
The "delete_on_termination" option was also added.
This commit follows suit of #1897 by fixing volume-related
parameters which allow the volume attach acceptance test
to work. It also re-enables the volume attach test.
