The commit is pretty complete and has a tested/working provisioner for
both SSH and WinRM. There are a few tests, but we maybe need another
few to have better coverage. Docs are also included…
* ctiwald/ct/fix-protocol-problem:
aws: Document the odd protocol = "-1" behavior in security groups.
aws: Fixup structure_test to handle new expandIPPerms behavior.
aws: Add security group acceptance tests for protocol -1 fixes.
aws: error on expndIPPerms(...) if our ports and protocol conflict.
Users can input a limited number of protocol names (e.g. "tcp") as
inputs to network ACL rules, but the API only supports valid protocol
number:
http://www.iana.org/assignments/protocol-numbers/protocol-numbers.xhtml
Preserve the convenience of protocol names and simultaneously support
numbers by only writing numbers to the state file. Also use numbers
when hashing the rules, to keep everything consistent.
AWS will accept any overly-specific IP/mask combination, such as
10.1.2.2/24, but will store it by its implied network: 10.1.2.0/24.
This results in hashing errors, because the remote API will return
hashing results out of sync with the local configuration file.
Enforce a stricter API rule than AWS. Force users to use valid masks,
and run a quick calculation on their input to discover their intent.
AWS doesn't store ports for -1 protocol rules, thus the read from the
API will always come up with a different hash. Force the user to make a
deliberate port choice when enabling -1 protocol rules. All from_port
and to_port's on these rules must be 0.
AWS includes default rules with all network ACL resources which cannot
be modified by the user. Don't attempt to store them locally or change
them remotely if they are already stored -- it'll consistently result
in hashing problems.
resourceAwsNetworkAclRead swallowed these errors resulting in rules
that never properly updated. Implement an entry-to-maplist function
that'll allow us to write something that Set knows how to read.
If an AutoScalingGroup is in the middle of performing a Scaling
Activity, it cannot be deleted, and yields a ScalingActivityInProgress
error.
Retry the delete for up to 5m so we don't choke on this error. It's
telling us something's in progress, so we'll keep trying until the
scaling activity completed.
On ASG creation, waits for up to 10m for desired_capacity or min_size
healthy nodes to show up in the group before continuing.
With CBD and proper HealthCheck tuning, this allows us guarantee safe
ASG replacement.
