Synopsis ¶

This module allows the user to create, update and delete a Subnet resource in Oracle Cloud Infrastructure
For state=present, creates a new subnet in the specified VCN. You can’t change the size of the subnet after creation, so it’s important to think about the size of subnets you need before creating them. For more information, see VCNs and Subnets. For information on the number of subnets you can have in a VCN, see Service Limits.
For the purposes of access control, you must provide the OCID of the compartment where you want the subnet to reside. Notice that the subnet doesn’t have to be in the same compartment as the VCN, route tables, or other Networking Service components. If you’re not sure which compartment to use, put the subnet in the same compartment as the VCN. For more information about compartments and access control, see Overview of the IAM Service. For information about OCIDs, see Resource Identifiers.
You may optionally associate a route table with the subnet. If you don’t, the subnet will use the VCN’s default route table. For more information about route tables, see Route Tables.
You may optionally associate a security list with the subnet. If you don’t, the subnet will use the VCN’s default security list. For more information about security lists, see Security Lists.
You may optionally associate a set of DHCP options with the subnet. If you don’t, the subnet will use the VCN’s default set. For more information about DHCP options, see DHCP Options.
You may optionally specify a display name for the subnet, otherwise a default is provided. It does not have to be unique, and you can change it. Avoid entering confidential information.
You can also add a DNS label for the subnet, which is required if you want the Internet and VCN Resolver to resolve hostnames for instances in the subnet. For more information, see DNS in Your Virtual Cloud Network.
This resource has the following action operations in the oracle.oci.oci_network_subnet_actions module: add_ipv6_subnet_cidr, change_compartment, remove_ipv6_subnet_cidr.

Requirements ¶

The below requirements are needed on the host that executes this module.

python >= 3.6
Python SDK for Oracle Cloud Infrastructure https://oracle-cloud-infrastructure-python-sdk.readthedocs.io

Parameters ¶

Parameter	Choices/Defaults	Comments
api_user string		The OCID of the user, on whose behalf, OCI APIs are invoked. If not set, then the value of the OCI_USER_ID environment variable, if any, is used. This option is required if the user is not specified through a configuration file (See `config_file_location`). To get the user's OCID, please refer https://docs.us-phoenix-1.oraclecloud.com/Content/API/Concepts/apisigningkey.htm.
api_user_fingerprint string		Fingerprint for the key pair being used. If not set, then the value of the OCI_USER_FINGERPRINT environment variable, if any, is used. This option is required if the key fingerprint is not specified through a configuration file (See `config_file_location`). To get the key pair's fingerprint value please refer https://docs.us-phoenix-1.oraclecloud.com/Content/API/Concepts/apisigningkey.htm.
api_user_key_file string		Full path and filename of the private key (in PEM format). If not set, then the value of the OCI_USER_KEY_FILE variable, if any, is used. This option is required if the private key is not specified through a configuration file (See `config_file_location`). If the key is encrypted with a pass-phrase, the `api_user_key_pass_phrase` option must also be provided.
api_user_key_pass_phrase string		Passphrase used by the key referenced in `api_user_key_file`, if it is encrypted. If not set, then the value of the OCI_USER_KEY_PASS_PHRASE variable, if any, is used. This option is required if the key passphrase is not specified through a configuration file (See `config_file_location`).
auth_purpose string	Choices: service_principal	The auth purpose which can be used in conjunction with 'auth_type=instance_principal'. The default auth_purpose for instance_principal is None.
auth_type string	Choices: api_key ← instance_principal instance_obo_user resource_principal security_token	The type of authentication to use for making API requests. By default `auth_type="api_key"` based authentication is performed and the API key (see api_user_key_file) in your config file will be used. If this 'auth_type' module option is not specified, the value of the OCI_ANSIBLE_AUTH_TYPE, if any, is used. Use `auth_type="instance_principal"` to use instance principal based authentication when running ansible playbooks within an OCI compute instance.
availability_domain string		Controls whether the subnet is regional or specific to an availability domain. Oracle recommends creating regional subnets because they're more flexible and make it easier to implement failover across availability domains. Originally, AD-specific subnets were the only kind available to use. To create a regional subnet, omit this attribute. Then any resources later created in this subnet (such as a Compute instance) can be created in any availability domain in the region. To instead create an AD-specific subnet, set this attribute to the availability domain you want this subnet to be in. Then any resources later created in this subnet can only be created in that availability domain. Example: `Uocm:PHX-AD-1`
cert_bundle string		The full path to a CA certificate bundle to be used for SSL verification. This will override the default CA certificate bundle. If not set, then the value of the OCI_ANSIBLE_CERT_BUNDLE variable, if any, is used.
cidr_block string		The CIDR IP address range of the subnet. The CIDR must maintain the following rules - a. The CIDR block is valid and correctly formatted. b. The new range is within one of the parent VCN ranges. Example: `10.0.1.0/24` Required for create using state=present. This parameter is updatable.
compartment_id string		The OCID of the compartment to contain the subnet. Required for create using state=present. Required for update when environment variable `OCI_USE_NAME_AS_IDENTIFIER` is set. Required for delete when environment variable `OCI_USE_NAME_AS_IDENTIFIER` is set.
config_file_location string		Path to configuration file. If not set then the value of the OCI_CONFIG_FILE environment variable, if any, is used. Otherwise, defaults to ~/.oci/config.
config_profile_name string		The profile to load from the config file referenced by `config_file_location`. If not set, then the value of the OCI_CONFIG_PROFILE environment variable, if any, is used. Otherwise, defaults to the "DEFAULT" profile in `config_file_location`.
defined_tags dictionary		Defined tags for this resource. Each key is predefined and scoped to a namespace. For more information, see Resource Tags. Example: `{"Operations": {"CostCenter": "42"}}` This parameter is updatable.
dhcp_options_id string		The OCID of the set of DHCP options the subnet will use. If you don't provide a value, the subnet uses the VCN's default set of DHCP options. This parameter is updatable.
display_name string		A user-friendly name. Does not have to be unique, and it's changeable. Avoid entering confidential information. Required for create, update, delete when environment variable `OCI_USE_NAME_AS_IDENTIFIER` is set. This parameter is updatable when `OCI_USE_NAME_AS_IDENTIFIER` is not set. aliases: name
dns_label string		A DNS label for the subnet, used in conjunction with the VNIC's hostname and VCN's DNS label to form a fully qualified domain name (FQDN) for each VNIC within this subnet (for example, `bminstance1.subnet123.vcn1.oraclevcn.com`). Must be an alphanumeric string that begins with a letter and is unique within the VCN. The value cannot be changed. This value must be set if you want to use the Internet and VCN Resolver to resolve the hostnames of instances in the subnet. It can only be set if the VCN itself was created with a DNS label. For more information, see DNS in Your Virtual Cloud Network. Example: `subnet123`
force_create boolean	Choices: no ← yes	Whether to attempt non-idempotent creation of a resource. By default, create resource is an idempotent operation, and doesn't create the resource if it already exists. Setting this option to true, forcefully creates a copy of the resource, even if it already exists.This option is mutually exclusive with key_by.
freeform_tags dictionary		Free-form tags for this resource. Each tag is a simple key-value pair with no predefined name, type, or namespace. For more information, see Resource Tags. Example: `{"Department": "Finance"}` This parameter is updatable.
ipv6_cidr_block string		Use this to enable IPv6 addressing for this subnet. The VCN must be enabled for IPv6. You can't change this subnet characteristic later. All subnets are /64 in size. The subnet portion of the IPv6 address is the fourth hextet from the left (1111 in the following example). For important details about IPv6 addressing in a VCN, see IPv6 Addresses. Example: `2001:0db8:0123:1111::/64` This parameter is updatable.
ipv6_cidr_blocks list / elements=string		The list of all IPv6 prefixes (Oracle allocated IPv6 GUA, ULA or private IPv6 prefixes, BYOIPv6 prefixes) for the subnet that meets the following criteria: - The prefixes must be valid. - Multiple prefixes must not overlap each other or the on-premises network prefix. - The number of prefixes must not exceed the limit of IPv6 prefixes allowed to a subnet. This parameter is updatable.
key_by list / elements=string		The list of attributes of this resource which should be used to uniquely identify an instance of the resource. By default, all the attributes of a resource are used to uniquely identify a resource.
prohibit_internet_ingress boolean	Choices: no yes	Whether to disallow ingress internet traffic to VNICs within this subnet. Defaults to false. For IPv6, if `prohibitInternetIngress` is set to `true`, internet access is not allowed for any IPv6s assigned to VNICs in the subnet. Otherwise, ingress internet traffic is allowed by default. `prohibitPublicIpOnVnic` will be set to the value of `prohibitInternetIngress` to dictate IPv4 behavior in this subnet. Only one or the other flag should be specified. Example: `true`
prohibit_public_ip_on_vnic boolean	Choices: no yes	Whether VNICs within this subnet can have public IP addresses. Defaults to false, which means VNICs created in this subnet will automatically be assigned public IP addresses unless specified otherwise during instance launch or VNIC creation (with the `assignPublicIp` flag in CreateVnicDetails). If `prohibitPublicIpOnVnic` is set to true, VNICs created in this subnet cannot have public IP addresses (that is, it's a private subnet). If you intend to use an IPv6 prefix, you should use the flag `prohibitInternetIngress` to specify ingress internet traffic behavior of the subnet. Example: `true`
realm_specific_endpoint_template_enabled boolean	Choices: no yes	Enable/Disable realm specific endpoint template for service client. By Default, realm specific endpoint template is disabled. If not set, then the value of the OCI_REALM_SPECIFIC_SERVICE_ENDPOINT_TEMPLATE_ENABLED variable, if any, is used.
region string		The Oracle Cloud Infrastructure region to use for all OCI API requests. If not set, then the value of the OCI_REGION variable, if any, is used. This option is required if the region is not specified through a configuration file (See `config_file_location`). Please refer to https://docs.us-phoenix-1.oraclecloud.com/Content/General/Concepts/regions.htm for more information on OCI regions.
route_table_id string		The OCID of the route table the subnet will use. If you don't provide a value, the subnet uses the VCN's default route table. This parameter is updatable.
security_list_ids list / elements=string		The OCIDs of the security list or lists the subnet will use. If you don't provide a value, the subnet uses the VCN's default security list. Remember that security lists are associated with the subnet, but the rules are applied to the individual VNICs in the subnet. This parameter is updatable.
state string	Choices: present ← absent	The state of the Subnet. Use state=present to create or update a Subnet. Use state=absent to delete a Subnet.
subnet_id string		The OCID of the subnet. Required for update using state=present when environment variable `OCI_USE_NAME_AS_IDENTIFIER` is not set. Required for delete using state=absent when environment variable `OCI_USE_NAME_AS_IDENTIFIER` is not set. aliases: id
tenancy string		OCID of your tenancy. If not set, then the value of the OCI_TENANCY variable, if any, is used. This option is required if the tenancy OCID is not specified through a configuration file (See `config_file_location`). To get the tenancy OCID, please refer https://docs.us-phoenix-1.oraclecloud.com/Content/API/Concepts/apisigningkey.htm
vcn_id string		The OCID of the VCN to contain the subnet. Required for create using state=present.
wait boolean	Choices: no yes ←	Whether to wait for create or delete operation to complete.
wait_timeout integer		Time, in seconds, to wait when wait=yes. Defaults to 1200 for most of the services but some services might have a longer wait timeout.

	availability_domain string	on success	The subnet's availability domain. This attribute will be null if this is a regional subnet instead of an AD-specific subnet. Oracle recommends creating regional subnets. Example: `Uocm:PHX-AD-1` Sample: Uocm:PHX-AD-1
	cidr_block string	on success	The subnet's CIDR block. Example: `10.0.1.0/24` Sample: cidr_block_example
	compartment_id string	on success	The OCID of the compartment containing the subnet. Sample: ocid1.compartment.oc1..xxxxxxEXAMPLExxxxxx
	defined_tags dictionary	on success	Defined tags for this resource. Each key is predefined and scoped to a namespace. For more information, see Resource Tags. Example: `{"Operations": {"CostCenter": "42"}}` Sample: {'Operations': {'CostCenter': 'US'}}
	dhcp_options_id string	on success	The OCID of the set of DHCP options that the subnet uses. Sample: ocid1.dhcpoptions.oc1..xxxxxxEXAMPLExxxxxx
	display_name string	on success	A user-friendly name. Does not have to be unique, and it's changeable. Avoid entering confidential information. Sample: display_name_example
	dns_label string	on success	A DNS label for the subnet, used in conjunction with the VNIC's hostname and VCN's DNS label to form a fully qualified domain name (FQDN) for each VNIC within this subnet (for example, `bminstance1.subnet123.vcn1.oraclevcn.com`). Must be an alphanumeric string that begins with a letter and is unique within the VCN. The value cannot be changed. The absence of this parameter means the Internet and VCN Resolver will not resolve hostnames of instances in this subnet. For more information, see DNS in Your Virtual Cloud Network. Example: `subnet123` Sample: dns_label_example
	freeform_tags dictionary	on success	Free-form tags for this resource. Each tag is a simple key-value pair with no predefined name, type, or namespace. For more information, see Resource Tags. Example: `{"Department": "Finance"}` Sample: {'Department': 'Finance'}
	id string	on success	The subnet's Oracle ID (OCID). Sample: ocid1.resource.oc1..xxxxxxEXAMPLExxxxxx
	ipv6_cidr_block string	on success	For an IPv6-enabled subnet, this is the IPv6 prefix for the subnet's IP address space. The subnet size is always /64. See IPv6 Addresses. Example: `2001:0db8:0123:1111::/64` Sample: ipv6_cidr_block_example

If it is set to false, VNICs created in this subnet will automatically be assigned public IP addresses unless specified otherwise during instance launch or VNIC creation (with the `assignPublicIp` flag in CreateVnicDetails). If `prohibitInternetIngress` is set to true, VNICs created in this subnet cannot have public IP addresses (that is, it's a privatesubnet). For IPv6, if `prohibitInternetIngress` is set to `true`, internet access is not allowed for any IPv6s assigned to VNICs in the subnet. Otherwise, ingress internet traffic is allowed by default. Example: `true` Sample: True
	prohibit_public_ip_on_vnic boolean	on success	Whether VNICs within this subnet can have public IP addresses. Defaults to false, which means VNICs created in this subnet will automatically be assigned public IP addresses unless specified otherwise during instance launch or VNIC creation (with the `assignPublicIp` flag in CreateVnicDetails). If `prohibitPublicIpOnVnic` is set to true, VNICs created in this subnet cannot have public IP addresses (that is, it's a private subnet). Example: `true` Sample: True
	route_table_id string	on success	The OCID of the route table that the subnet uses. Sample: ocid1.routetable.oc1..xxxxxxEXAMPLExxxxxx
