This repository holds a external plugin for a Terraform provider to manage resources within PHPIPAM, an open source IP address management system.
PHPIPAM is an open source IP address management system written in PHP. It has an evolving API that allows for the management and lookup of data that has been entered into the system. Through our Go integration phpipam-sdk-go, we have been able to take this API and integrate it into Terraform, allowing for the management and lookup of sections, VLANs, subnets, and IP addresses, entirely within Terraform.
See the Plugin Basics page of the Terraform docs to see how to plunk this into your config. Check the releases page of this repo to get releases for Linux, OS X, and Windows.
After installation, to use the plugin, simply use any of its resources or data
sources (such as phpipam_subnet or phpipam_address in a Terraform
configuration.
Credentials can be supplied via configuration variables to the phpipam
provider instance, or via environment variables. These are documented in the
next section.
You can see the following example below for a simple usage example that reserves
the first available IP address in a subnet. This address could then be passed
along to the configuration for a VM, say, for example, a
vsphere_virtual_machine resource.
provider "phpipam" {
app_id = "test"
endpoint = "https://phpipam.example.com/api"
password = "PHPIPAM_PASSWORD"
username = "Admin"
}
data "phpipam_subnet" "subnet" {
subnet_address = "10.10.2.0"
subnet_mask = 24
}
data "phpipam_first_free_address" "next_address" {
subnet_id = "${data.phpipam_subnet.subnet.subnet_id}"
}
resource "phpipam_address" {
subnet_id = "${data.phpipam_subnet.subnet.subnet_id}"
ip_address = "${data.phpipam_first_free_address.next_address.ip_address}"
hostname = "tf-test-host.example.internal"
description = "Managed by Terraform"
lifecycle {
ignore_changes = [
"subnet_id",
"ip_address",
]
}
}
The options for the plugin are as follows:
app_id- The API application ID, configured in the PHPIPAM API panel. This application ID should have read/write access if you are planning to use the resources, but read-only access should be sufficient if you are only using the data sources. Can also be supplied by thePHPIPAM_APP_IDenvironment variable.endpoint- The full URL to the PHPIPAM API endpoint, such ashttps://phpipam.example.com/api. Can also be supplied by thePHPIPAM_ENDPOINT_ADDRenvironment variable.password- The password to access the PHPIPAM API with. Can also be supplied viaPHPIPAM_PASSWORDto prevent plain text password storage in config.username- The user name to access the PHPIPAM API with. Can also be supplied via thePHPIPAM_USER_NAMEvariable.
The following data sources are supplied by this plugin:
The phpipam_address data source allows one to get information about a specific
IP address within PHPIPAM. Use this address to get general information about a
specific IP address such as its host name, description and more.
Lookups for IP addresses can only happen at this time via its entry in the database, or the IP address itself. Future versions of this resource, when such features become generally available in the PHPIPAM API, will allow lookup based on host name, allowing for better ability for this resource to discover IP addresses that have been pre-assigned for a specific resource.
Example:
data "phpipam_address" "address" {
ip_address = "10.10.1.1"
}
output "address_description" {
value = "${data.phpipam_address.address.description}"
}
Example With description:
data "phpipam_address" "address" {
subnet_id = 3
description_match = "Customer 1"
}
output "address_description" {
value = "${data.phpipam_address.address.description}"
}
Example With custom_field_filter:
data "phpipam_address" "address" {
subnet_id = 3
custom_field_filter {
CustomTestAddresses = ".*terraform.*"
}
}
output "address_description" {
value = "${data.phpipam_address.address.description}"
}
The data source takes the following parameters:
address_id- The ID of the IP address in the PHPIPAM database.ip_address- The actual IP address in PHPIPAM.subnet_id- The ID of the subnet that the address resides in. This is required to search on thedescriptionorhostnamefields.description- The description of the IP address.subnet_idis required when using this field.hostname- The host name of the IP address.subnet_idis required when using this field.custom_field_filter- A map of custom fields to search for. The filter values are regular expressions that follow the RE2 syntax for which you can find documentation here. All fields need to match for the match to succeed.
description, hostname, and custom_field_filter fields return
the first match found without any warnings. If you are looking to return
multiple addresses, combine this data source with the phpipam_addresses data
source.
custom_field_filter value is the
equivalent to a regular expression that matches everything, and hence will
return the first address it sees in the subnet.
Arguments are processed in the following order of precedence:
address_idip_addresssubnet_id, and either one ofdescription,hostname, orcustom_field_filter
The following attributes are exported:
address_id- The ID of the IP address in the PHPIPAM database.ip_address- the IP address.subnet_id- The database ID of the subnet this IP address belongs to.is_gateway-trueif this IP address has been designated as a gateway.description- The description provided to this IP address.hostname- The hostname supplied to this IP address.owner- The owner name provided to this IP address.mac_address- The MAC address provided to this IP address.state_tag_id- The tag ID in the database for the IP address' specific state. NOTE: This is currently represented as an integer but may change to the specific string representation at a later time.skip_ptr_record-trueif PTR records are not being created for this IP address.ptr_record_id- The ID of the associated PTR record in the PHPIPAM database.device_id- The ID of the associated device in the PHPIPAM database.switch_port_label- A string port label that is associated with this address.note- The note supplied to this IP address.last_seen- The last time this IP address answered ping probes.exclude_ping-trueif this address is excluded from ping probes.edit_date- The last time this resource was modified.custom_fields- A key/value map of custom fields for this address.
The phpipam_addresses data source allows you to search for IP addresses, much
in the same way as you can in the single-form phpipam_address data source.
However, multiple addresses are returned from this data source as a single list
of address IDs as they are found in the PHPIPAM database. You can then use the
single-form phpipam_address data source to extract the IP data for each
matched address in the database.
Example:
data "phpipam_addresses" "address_search" {
subnet_id = 3
custom_field_filter {
CustomTestAddresses = ".*terraform.*"
}
}
data "phpipam_address" "addresses" {
count = "${length(data.phpipam_addresses.address_search.address_ids)}"
address_id = "${element(data.phpipam_addresses.address_search.address_ids, count.index)}"
}
output "ip_addresses" {
value = ["${data.phpipam_address.addresses.*.ip_address}"]
}
The data source takes the following parameters:
subnet_id(Required) - The ID of the subnet that the address resides in. This is required to search on thedescriptionorhostnamefields.
One of the following fields is required alongside subnet_id:
description- The description of the IP address.subnet_idis required when using this field.hostname- The host name of the IP address.subnet_idis required when using this field.custom_field_filter- A map of custom fields to search for. The filter values are regular expressions that follow the RE2 syntax for which you can find documentation here. All fields need to match for the match to succeed.
custom_field_filter value is the
equivalent to a regular expression that matches everything, and hence will
return all addresses that contain the referenced custom field key!
The following attributes are exported:
address_ids- A list of discovered IP address IDs.
The phpipam_first_free_address data source allows you to get the next
available IP address in a specific subnet in PHPIPAM. Using this resource allows
you to automatically allocate an IP address that can be used as an IP address in
resources such as vsphere_virtual_machine, or other virtual machine-like
resources that require static IP addresses.
Note that not having any addresses available will cause the Terraform run to fail. Conversely, marking a subnet as unavailable or used will not prevent this data source from returning an IP address, so be aware of this while using this resource.
Example:
// Look up the subnet
data "phpipam_subnet" "subnet" {
subnet_address = "10.10.2.0"
subnet_mask = 24
}
// Get the first available address
data "phpipam_first_free_address" "next_address" {
subnet_id = "${data.phpipam_subnet.subnet.subnet_id}"
}
// Reserve the address. Note that we use ignore_changes here to ensure that we
// don't end up re-allocating this address on future Terraform runs.
resource "phpipam_address" {
subnet_id = "${data.phpipam_subnet.subnet.subnet_id}"
ip_address = "${data.phpipam_first_free_address.next_address.ip_address}"
hostname = "tf-test-host.example.internal"
description = "Managed by Terraform"
lifecycle {
ignore_changes = [
"subnet_id",
"ip_address",
]
}
}
// Supply the IP address to an instance. Note that we are also ignoring
// network_interface here to ensure the IP address does not get re-calculated.
resource "vsphere_virtual_machine" "web" {
name = "terraform-web"
vcpu = 2
memory = 4096
network_interface {
label = "VM Network"
ipv4_address = "${data.phpipam_first_free_address.next_address.ip_address}"
}
disk {
template = "centos-7"
}
ignore_changes = [
"network_interface",
]
}
The data source takes the following parameters:
subnet_id- The ID of the subnet to look up the address in.
The following attributes are exported:
ip_address- The next available IP address.
The phpipam_section data source allows one to look up a specific section,
either by database ID or name. This data can then be used to manage other parts
of PHPIPAM, such as in the event that the section name is known but not its ID,
which is required for managing subnets.
Example:
data "phpipam_section" "section" {
name = "Customers"
}
resource "phpipam_subnet" "subnet" {
section_id = "${data.phpipam_section.section.section_id}"
subnet_address = "10.10.3.0"
subnet_mask = 24
}
The data source takes the following parameters:
section_id- The ID of the section to look up.name- The name of the section to look up.
One of section_id or name must be supplied. If both are supplied,
section_id is used.
The following attributes are exported:
section_id- The ID of the section in the PHPIPAM database.name- The name of the section.description- The section's description.master_section_id- The ID of the parent section in the PHPIPAM database.permissions- A JSON representation of permissions for this section.strict_mode-trueif this subnet is set up to check that IP addresses are valid for the subnets they are in.subnet_ordering- How subnets in this section are ordered.display_order- The section's display order number.edit_date- The date this resource was last edited.show_vlan_in_subnet_listing-trueif VLANs are being shown in the subnet listing for this section.show_vrf_in_subnet_listing-trueif VRFs are being shown in the subnet listing for this section.show_supernet_only-trueif supernets are only being shown in the subnet listing.dns_resolver_id- The ID of the DNS resolver to use in the section.
The phpipam_subnet data source gets information on a subnet such as its ID
(required for creating addresses), description, and more.
Example:
// Look up the subnet
data "phpipam_subnet" "subnet" {
subnet_address = "10.10.2.0"
subnet_mask = 24
}
// Reserve the address.
resource "phpipam_address" {
subnet_id = "${data.phpipam_subnet.subnet.subnet_id}"
ip_address = "10.10.2.10"
hostname = "tf-test-host.example.internal"
description = "Managed by Terraform"
}
Example with description_match:
// Look up the subnet (matching on either case of "customer")
data "phpipam_subnet" "subnet" {
section_id = 1
description_match = "[Cc]ustomer 2"
}
// Get the first available address
data "phpipam_first_free_address" "next_address" {
subnet_id = "${data.phpipam_subnet.subnet.subnet_id}"
}
// Reserve the address. Note that we use ignore_changes here to ensure that we
// don't end up re-allocating this address on future Terraform runs.
resource "phpipam_address" {
subnet_id = "${data.phpipam_subnet.subnet.subnet_id}"
ip_address = "${data.phpipam_first_free_address.next_address.ip_address}"
hostname = "tf-test-host.example.internal"
description = "Managed by Terraform"
lifecycle {
ignore_changes = [
"subnet_id",
"ip_address",
]
}
}
Example With custom_field_filter:
// Look up the subnet
data "phpipam_subnet" "subnet" {
section_id = 1
custom_field_filter = {
CustomTestSubnets = ".*terraform.*"
}
}
// Get the first available address
data "phpipam_first_free_address" "next_address" {
subnet_id = "${data.phpipam_subnet.subnet.subnet_id}"
}
// Reserve the address. Note that we use ignore_changes here to ensure that we
// don't end up re-allocating this address on future Terraform runs.
resource "phpipam_address" {
subnet_id = "${data.phpipam_subnet.subnet.subnet_id}"
ip_address = "${data.phpipam_first_free_address.next_address.ip_address}"
hostname = "tf-test-host.example.internal"
description = "Managed by Terraform"
lifecycle {
ignore_changes = [
"subnet_id",
"ip_address",
]
}
}
The data source takes the following parameters:
section_id- The ID of the section of the subnet. Required if you are looking up a subnet using thedescriptionordescription_matcharguments.subnet_id- The ID of the subnet to look up.subnet_address- The network address of the subnet to look up.subnet_mask- The subnet mask, in bits, of the subnet to look up.description- The subnet's description.section_idis required if you want to use this option.description_match- A regular expression to match against when searching for a subnet.section_idis required if you want to use this option.custom_field_filter- A map of custom fields to search for. The filter values are regular expressions that follow the RE2 syntax for which you can find documentation here. All fields need to match for the match to succeed.
description, description_match and
custom_field_filter fields return the first match found without any warnings.
Conversely, the resource fails if it somehow finds multiple results on a CIDR
(subnet and mask) search - this is to assert that you are getting the subnet you
requested. If you want to return multiple results, combine this data source with
the phpipam_subnets data source.
custom_field_filter value is the
equivalent to a regular expression that matches everything, and hence will
return the first subnetit sees in the section.
Arguments are processed in the following order of precedence:
subnet_idsubnet_addressandsubnet_masksection_id, and either one ofdescription,description_match, orcustom_field_filter
The following attributes are exported:
subnet_id- The ID of the subnet in the PHPIPAM database.subnet_address- The network address of the subnet.subnet_mask- The subnet mask, in bits.description- The description set for the subnet.section_id- The ID of the section for this address in the PHPIPAM database.linked_subnet_id- The ID of the linked subnet in the PHPIPAM database.vlan_id- The ID of the VLAN for this subnet in the PHPIPAM database.vrf_id- The ID of the VRF for this subnet in the PHPIPAM database.master_subnet_id- The ID of the parent subnet for this subnet in the PHPIPAM database.nameserver_id- The ID of the nameserver used to assign PTR records for this subnet.show_name-trueif the subnet name is are shown in the section, instead of the network address.permissions- A JSON representation of the permissions associated with this subnet.create_ptr_records-trueif PTR records are created for addresses in this subnet.display_hostnames-trueif hostnames are displayed instead of IP addresses in the address listing for this subnet.allow_ip_requests-trueif the subnet allows IP requests in PHPIPAM.scan_agent_id- The ID of the ping scan agent that is used for this subnet.include_in_ping-trueif this subnet is included in ping probes.host_discovery_enabled-trueif this subnet is included in new host scans.is_folder-trueif this subnet is a folder and not an actual subnet.is_full-trueif the subnet has been marked as full.state_tag_id- The ID of the state tag for this subnet. This may become an actual string representation of this at a later time (example:Used).utilization_threshold- The subnet's utilization threshold.location_id- The ID of the location for this subnet.edit_date- The date this resource was last updated.custom_fields- A key/value map of custom fields for this subnet.
The phpipam_subnets data source allows you to search for subnets, much in the
same way as you can in the single-form phpipam_subnet data source. However,
multiple subnets are returned from this data source as a single list of subnet
IDs as they are found in the PHPIPAM database. You can then use the single-form
phpipam_subnet data source to extract the subnet data for each matched network
in the database.
Example:
data "phpipam_subnets" "subnet_search" {
subnet_id = 3
custom_field_filter {
CustomTestSubnets = ".*terraform.*"
}
}
data "phpipam_subnet" "subnets" {
count = "${length(data.phpipam_subnets.subnet_search.subnet_ids)}"
subnet_id = "${element(data.phpipam_subnets.subnet_search.subnet_ids, count.index)}"
}
output "subnet_addresses" {
value = ["${data.phpipam_subnet.subnets.*.ip_address}"]
}
output "subnet_cidrs" {
value = ["${formatlist("%s/%d", data.phpipam_subnet.subnets.*.subnet_address, data.phpipam_subnet.subnets.*.subnet_mask)}"]
}
The data source takes the following parameters:
section_id(Required) - The ID of the section of the subnet.
One of the following below parameters is required:
description- The subnet's description.description_match- A regular expression to match against when searching for a subnet.custom_field_filter- A map of custom fields to search for. The filter values are regular expressions. All fields need to match for the match to succeed.
You can find documentation for the regular expression syntax used with the
description_match and custom_field_filter attributes
here.
custom_field_filter value is the
equivalent to a regular expression that matches everything, and hence will
return all subnets that contain the referenced custom field key!
The following attributes are exported:
subnet_ids- A list of subnet IDs that match the given criteria.
The phpipam_vlan data source allows one to look up a VLAN in the PHPIPAM
database. This can then be used to assign a VLAN to a subnet in the
phpipam_subnet resource. It can also be used to gather other information on
the VLAN.
Example:
data "phpipam_section" "section" {
name = "Customers"
}
data "phpipam_vlan" "vlan" {
number = 1000
}
resource "phpipam_subnet" "subnet" {
section_id = "${data.phpipam_section.section.section_id}"
subnet_address = "10.10.3.0"
subnet_mask = 24
vlan_id = "${data.phpipam_vlan.vlan.vlan_id}"
}
The data source takes the following parameters:
vlan_id- The ID of the VLAN to look up. NOTE: this is the database ID, not the VLAN number - if you need this, use thenumberparameter.number- The number of the VLAN to look up.
One of vlan_id or number must be supplied. If both are supplied,
vlan_id is used.
The following attributes are exported:
vlan_id- The ID of the VLAN to look up. NOTE: this is the database ID, not the VLAN number - if you need this, use thenumberparameter.number- The number of the VLAN (the actual VLAN ID on your switch).l2_domain_id- The layer 2 domain ID in the PHPIPAM database.name- The name/label of the VLAN.description- The description supplied to the VLAN.edit_date- The date this resource was last updated.custom_fields- A key/value map of custom fields for this VLAN.
The following resources are supplied by this plugin:
The phpipam_address resource manages an IP address in PHPIPAM. You can use it
to create IP address reservations for IP addresses that have been created by
other Terraform resources, or supplied by the phpipam_first_free_address data
source. An example usage is below.
phpipam_first_free_address to get the first
free IP address in a specific subnet, make sure you set subnet_id and
ip_address as ignored attributes with the ignore_changes lifecycle
attribute. This will prevent Terraform from perpetually deleting and
re-allocating the address when it sees a different available IP address in the
phpipam_first_free_address data source.
Example:
// Look up the subnet
data "phpipam_subnet" "subnet" {
subnet_address = "10.10.2.0"
subnet_mask = 24
}
// Get the first available address
data "phpipam_first_free_address" "next_address" {
subnet_id = "${data.phpipam_subnet.subnet.subnet_id}"
}
// Reserve the address. Note that we use ignore_changes here to ensure that we
// don't end up re-allocating this address on future Terraform runs.
resource "phpipam_address" {
subnet_id = "${data.phpipam_subnet.subnet.subnet_id}"
ip_address = "${data.phpipam_first_free_address.next_address.ip_address}"
hostname = "tf-test-host.example.internal"
description = "Managed by Terraform"
custom_fields = {
CustomTestAddresses = "terraform-test"
}
lifecycle {
ignore_changes = [

The phpipam_section resource manages a PHPIPAM section - a top-level category
that subnets and IP addresses are entered into. Use this resource if you want to
manage a section entirely from Terraform. If you just need to get information on
a section use the phpipam_section data source instead.
Example:
// Create a section
resource "phpipam_section" "section" {
name = "tf-test"
description = "Terraform test section"
}
The resource takes the following parameters:
name(Required) - The name of the section.description(Optional) - The section's description.master_section_id(Optional) - The ID of the parent section in the PHPIPAM database.strict_mode(Optional) -trueif this subnet is set up to check that IP addresses are valid for the subnets they are in.subnet_ordering(Optional) - How subnets in this section are ordered.display_order(Optional) - The section's display order number.show_vlan_in_subnet_listing(Optional) -trueif VLANs are being shown in the subnet listing for this section.show_vrf_in_subnet_listing(Optional) -trueif VRFs are being shown in the subnet listing for this section.show_supernet_only(Optional) -trueif supernets are only being shown in the subnet listing.dns_resolver_id(Optional) - The ID of the DNS resolver to use in the section.
The following attributes are exported:

The phpipam_subnet resource can be used to create and manage a subnet in
PHPIPAM. Use it to manage details on subnets you create in Terraform for other
things, such as storing the IDs of the subnets you create for AWS, or for a full
top-down management of subnets and IP addresses in Terraform. If you just need
to get information on a subnet, use the phpipam_subnet data source instead.
Example:
