This data source allows one to look up the most recent AMI for a specific
set of parameters, much like aws ec2 describe-images in the AWS CLI.
Basically a refresh of hashicorp/terraform#4396, in data source form.
During accpeptance tests of some of the first data sources (see
hashicorp/terraform#6881 and hashicorp/terraform#6911),
"unknown resource type" errors have been coming up. Traced it down to
the ResourceCountTransformer, which transforms destroy nodes to a
graphNodeExpandedResourceDestroy node. This node's EvalTree() was still
indiscriminately using EvalApply for all resource types, versus
EvalReadDataApply. This accounts for both cases via EvalIf.
This commit adds the newly required OS_EXT_GW environment variable to
the devstack acceptance environment build suite. It also fixes some
space formatting in a test.
Previously the plan phase would produce a data diff only if no state was
already present. However, this is a faulty approach because a state will
already be present in the case where the data resource depends on a
managed resource that existed in state during refresh but became
computed during plan, due to a "forces new resource" diff.
Now we will produce a data diff regardless of the presence of the state
when the configuration is computed during the plan phase.
This fixes#6824.
This means it’s shown correctly in a plan and takes into account any
actions that are dependant on the tainted resource and, vice verse, any
actions that the tainted resource depends on.
So this changes the behaviour from saying this resource is tainted so
just forget about it and make sure it gets deleted in the background,
to saying I want that resource to be recreated (taking into account the
existing resource and it’s place in the graph).
Fixes#4474, where lookup() calls fail out the entire interpolation when
the provided key value is not found in the map. This will allow using
coalesce() along with lookup() to greatly improve module flexibility.
* Add per user, role and group policy attachment
* Add docs for new IAM policy attachment resources.
* Make policy attachment resources manage only 1 entity<->policy attachment
* provider/aws: Tidy up IAM Group/User/Role attachments
When two rules differ only in source security group, EC2 APIs return
them as a single rule, but Terraform requires separate
aws_security_group_rule resources.
6bdab07174 changed Read to set source_security_group_id (and
cidr_blocks) from the rule returned from EC2 and chose the first
source_security_group_id arbitrarily, which is wrong.
Makes TestAccAWSSecurityGroupRule_PartialMatching_Source pass again.
Also adds a comment noting that there is a bug in the new resource
importing feature.
Fixes#6728.
