No plaintext password for compute instance

Default Severity: medium

Explanation

Assigning a password to the compute instance using plaintext could lead to compromise; it would be preferable to use key-pairs as a login mechanism

Possible Impact

Including a plaintext password could lead to compromised instance

Suggested Resolution

Do not use plaintext passwords in terraform files

Insecure Example

The following example will fail the openstack-compute-no-plaintext-password check. 

 resource "openstack_compute_instance_v2" "bad_example" {
   name            = "basic"
   image_id        = "ad091b52-742f-469e-8f3c-fd81cadf0743"
   flavor_id       = "3"
   admin_pass      = "N0tSoS3cretP4ssw0rd"
   security_groups = ["default"]
   user_data       = "#cloud-config\nhostname: instance_1.example.com\nfqdn: instance_1.example.com"

   network {
     name = "my_network"
   }
 }

Secure Example

The following example will pass the openstack-compute-no-plaintext-password check. 

 resource "openstack_compute_instance_v2" "good_example" {
   name            = "basic"
   image_id        = "ad091b52-742f-469e-8f3c-fd81cadf0743"
   flavor_id       = "3"
   key_pair        = "my_key_pair_name"
   security_groups = ["default"]
   user_data       = "#cloud-config\nhostname: instance_1.example.com\nfqdn: instance_1.example.com"

   network {
     name = "my_network"
   }
 }
