openstack_compute_secgroup_v2

Manages a V2 security group resource within OpenStack.

Example Usage

resource "openstack_compute_secgroup_v2" "secgroup_1" {
  name = "my_secgroup"
  description = "my security group"
  rule {
    from_port = 22
    to_port = 22
    ip_protocol = "tcp"
    cidr = "0.0.0.0/0"
  }
  rule {
    from_port = 80
    to_port = 80
    ip_protocol = "tcp"
    cidr = "0.0.0.0/0"
  }
}

Argument Reference

The following arguments are supported:

  • region - (Required) The region in which to obtain the V2 Compute client. A Compute client is needed to create a security group. If omitted, the OS_REGION_NAME environment variable is used. Changing this creates a new security group.

  • name - (Required) A unique name for the security group. Changing this updates the name of an existing security group.

  • description - (Required) A description for the security group. Changing this updates the description of an existing security group.

  • rule - (Optional) A rule describing how the security group operates. The rule object structure is documented below. Changing this updates the security group rules. As shown in the example above, multiple rule blocks may be used.

The rule block supports:

  • from_port - (Required) An integer representing the lower bound of the port range to open. Changing this creates a new security group rule.

  • to_port - (Required) An integer representing the upper bound of the port range to open. Changing this creates a new security group rule.

  • ip_protocol - (Required) The protocol type that will be allowed. Changing this creates a new security group rule.

  • cidr - (Optional) Required if from_group_id or self is empty. The IP range that will be the source of network traffic to the security group. Use 0.0.0.0/0 to allow all IP addresses. Changing this creates a new security group rule. Cannot be combined with from_group_id or self.

  • from_group_id - (Optional) Required if cidr or self is empty. The ID of a group from which to forward traffic to the parent group. Changing this creates a new security group rule. Cannot be combined with cidr or self.

  • self - (Optional) Required if cidr and from_group_id is empty. If true, the security group itself will be added as a source to this ingress rule. Cannot be combined with cidr or from_group_id.

Attributes Reference

The following attributes are exported:

  • region - See Argument Reference above.
  • name - See Argument Reference above.
  • description - See Argument Reference above.
  • rule - See Argument Reference above.

Notes

ICMP Rules

When using ICMP as the ip_protocol, the from_port sets the ICMP type and the to_port sets the ICMP code. To allow all ICMP types, set each value to -1, like so:

rule {
  from_port = -1
  to_port = -1
  ip_protocol = "icmp"
  cidr = "0.0.0.0/0"
}

A list of ICMP types and codes can be found here.

Referencing Security Groups

When referencing a security group in a configuration (for example, a configuration creates a new security group and then needs to apply it to an instance being created in the same configuration), it is currently recommended to reference the security group by name and not by ID, like this:

resource "openstack_compute_instance_v2" "test-server" {
  name = "tf-test"
  image_id = "ad091b52-742f-469e-8f3c-fd81cadf0743"
  flavor_id = "3"
  key_pair = "my_key_pair_name"
  security_groups = ["${openstack_compute_secgroup_v2.secgroup_1.name}"]
}

Import

Security Groups can be imported using the id, e.g.

$ terraform import openstack_compute_secgroup_v2.my_secgroup 1bc30ee9-9d5b-4c30-bdd5-7f1e663f5edf
