Updates to objects in S3 are only eventually consistent. If the
RemoteClient has a DynamoDB table available, use that to store a
checksum of the last written state, so the object can be verified by the
next client to call Get.
Terraform currently doesn't have any sort of user feedback around
RefreshState/Get, so we poll only for a short time before returning an
error.
Prevent extra keys in the s3 envPrefix path from showing up as
listed environments.
Better handle keys containing slashes
Add tests for unexpected keys in s3.
This matches the consul cli behavior, where locks are cleaned up after
use.
Return an error from re-locking the state. This isn't required by the
Locker interface, but it's an added sanity check for state operations.
What was incorrect here was returning an empty ID and error, which would
indicate that Lock/Unlock isn't supported.
Use the aws provider code to create the clients for the s3 backend, so
that all the behavior matches that of the provider.
Remove the fake creds from the test, as the aws provider will attempt to
validate them.
This adds named state (environment) support to the S3 backend.
A state NAME will prepend the configured s3 key with `env:/NAME/`.
The default state will remain rooted in the bucket for backwards
compatibility.
Locks in DynamoDB use the S3 key as the as the primary key value, so
locking will work as expected for multiple states.
Move the S3 State from a legacy remote state to an official backend.
This increases test coverage, uses a set schema for configuration, and
will allow new backend features to be implemented for the S3 state, e.g.
"environments".
This adds a "lock" config (default true) to allow users to optionally
disable state locking with Consul. This is necessary if the token given
doesn't have session permission and is necessary for backwards
compatibility.
Gove LockInfo a Marshal method for easy serialization, and a String
method for more readable output.
Have the state.Locker implementations use LockError when possible to
return LockInfo and an error.
Use consul locks to implement state locking. The lock path is state path
+ "/.lock" which matches the consul cli default for locks. Lockinfo is
stored at path + "/.lockinfo".
