Terraform crashed during creating/importing aws_elasticache_replication_group

[bandesz]

Hi there,

Terraform Version

Terraform v0.7.7

Affected Resource(s)

• aws_elasticache_replication_group

Terraform Configuration Files

resource "aws_elasticache_replication_group" "xxx_redis" {
  replication_group_id = "xxx-redis"
  replication_group_description = "xxx-redis"
  node_type = "${var.node_type}"
  engine_version = "3.2.4"
  number_cache_clusters = "${var.node_count}"
  port = 6379
  parameter_group_name = "default.redis3.2.cluster.on"
  automatic_failover_enabled = true
  subnet_group_name = "${aws_elasticache_subnet_group.xxx_redis.name}"
  security_group_ids = ["${aws_security_group.xxx_redis.id}"]
}

Debug Output

See panic output

Panic Output

https://gist.github.com/bandesz/3ac0cfe33659a562bbb8df9ed4fcc674

Expected Behavior

Terraform should be able to create or import aws_elasticache_replication_group

Actual Behavior

CRASH

Steps to Reproduce

At first terraform apply failed with simply saying EOF error, but the AWS resource itself was created. Then terraform import crashed probably because of the same underlying issue.

@bandesz hi there!

I believe the issue you are seeing has been resolved recently via #9601, and will be included in the upcoming 0.7.8 release - which I believe is due very, very soon.

[stack72]

@bandesz, @kwilczynski is correct about #9601 :)

Sorry about the hassle here - we will get 0.7.8 released ASAP
