Terraform HaVip ENI attachment failing on Alibaba Cloud with unknown error

[hshimesh]

Hi there,

I am Himesh Sarkari from Palo Alto Networks. I have created a terraform script for a HA use case, but in that HaVip attachment to ENI is failing in Alibaba cloud. Though the 'terraform plan' is passing but in 'terraform apply' it fails stating "Unknown error" in Alibaba cloud.

Please help resolve this

######################################################### Terraform snippet

# Create HaVip
resource "alicloud_havip" "havip-untrust" {
  vswitch_id  = alicloud_vswitch.auto-pavmqa-DATA-Untrust.id
  ip_address = "10.x.x.x"
  ha_vip_name = "${local.res_grp}-HaVip1"
}

# Attach FW1 Untrust ENI to Untrust HaVip
resource "alicloud_havip_attachment" "havip-untrust-attachment1" {
  havip_id = alicloud_havip.havip-untrust.id
  instance_id = alicloud_network_interface.auto-pavmqa-DATA-FW1-Untrust.id
}

# Attach FW2 Untrust ENI to Untrust HaVip
resource "alicloud_havip_attachment" "havip-untrust-attachment2" {
  havip_id = alicloud_havip.havip-untrust.id
  instance_id = alicloud_network_interface.auto-pavmqa-DATA-FW2-Untrust.id
}
