When spinning up from a snapshot or a read replica, these fields are
now optional:
* allocated_storage
* engine
* password
* username
Some validation logic is added to make these fields required when
starting a database from scratch.
The documentation is updated accordingly.
When launching a new RDS instance in a VPC-default AWS account, trying to control which VPC the new RDS instance lands in is not apparent from the parameters available.
The following works:
```
resource "aws_db_subnet_group" "foo" {
name = "foo"
description = "DB Subnet for foo"
subnet_ids = ["${aws_subnet.foo_1a.id}", "${aws_subnet.foo_1b.id}"]
}
resource "aws_db_instance" "bar" {
...
db_subnet_group_name = "${aws_db_subnet_group.foo.name}"
...
}
```
Hopefully this doc update will help others
- Remove check on password for AWS RDS Instance
- Update documentation on AWS RDS Instance regarding DB Security Groups
- Change error handling to check error code from AWS API [ci skip]
Several of the arguments were optional, and if omitted, they are
calculated. Mark them as such in the schema to avoid triggering an
update.
Go back to storing the password in the state file. Without doing so,
there's no way for Terraform to know the password has changed. It should
be hashed, but then interpolating the password yields a hash instead of
the password.
Make the `name` parameter optional. It's not required in any engine, and
in some (MS SQL Server) it's not allowed at all.
Drop the `skip_final_snapshot` argument. If `final_snapshot_identifier`
isn't specified, then don't make a final snapshot. As things were, it
was possible to create a resource with neither of these arguments
specified which would later fail when it was to be deleted since the RDS
API requires exactly one of the two.
Resolves issue #689.
The Terraform configuration syntax defines what arrays are.
Use the word array consistently throughout the documentation
instead of list.
The corresponding JSON datatype is called array as well, and
since the Terraform configuration syntax is interoperable with
JSON it makes sense to use the term array to describe them.
