Properties

snat_ip^Required

snat_ip: typing.Union[str, IResolvable]

• Type: typing.Union[str, ros_cdk_core.IResolvable]

Property snatIp: The public IP address.

Separate multiple EIPs with commas.

snat_table_id^Required

snat_table_id: typing.Union[str, IResolvable]

• Type: typing.Union[str, ros_cdk_core.IResolvable]

Property snatTableId: The ID of the SNAT table.

eip_affinity^Optional

eip_affinity: typing.Union[typing.Union[int, float], IResolvable]

• Type: typing.Union[typing.Union[int, float], ros_cdk_core.IResolvable]

Property eipAffinity: Specifies whether to enable EIP affinity.

Valid values: 0: no 1: yes If EIP affinity is enabled and the SNAT entry is associated with multiple EIPs, a client uses the same EIP to access the Internet. Otherwise, the client uses an EIP selected from the associated EIPs to access the Internet.

network_interface_id^Optional

network_interface_id: typing.Union[str, IResolvable]

• Type: typing.Union[str, ros_cdk_core.IResolvable]

Property networkInterfaceId: The ID of the elastic network interface.

The IPv4 addresses of the elastic network interface will be used as the SNAT IP addresses.

snat_entry_name^Optional

snat_entry_name: typing.Union[str, IResolvable]

• Type: typing.Union[str, ros_cdk_core.IResolvable]

Property snatEntryName: The name of the SNAT entry.

The name must be 2 to 128 characters in length. It must start with a letter but cannot start with http:\/\/ or https:\/\/.

source_cidr^Optional

source_cidr: typing.Union[str, IResolvable]

• Type: typing.Union[str, ros_cdk_core.IResolvable]

Property sourceCidr: You can specify the CIDR block of a VPC, a vSwitch, or an ECS instance or enter a custom CIDR block.

You can specify an SNAT entry in the following ways:

• You can specify the CIDR block of the VPC where the NAT gateway is deployed. Then, all ECS instances in the VPC can access the Internet or external networks by using SNAT.
• You can specify the CIDR block of a vSwitch, for example, 192.168.1.0/24. Then, the ECS instances in the vSwitch can access the Internet or external networks by using SNAT.
• You can specify the IP address of an ECS instance, for example, 192.168.1.1/32. Then, the ECS instance can access the Internet or external networks by using SNAT.
• You can specify a custom CIDR block. Then, all ECS instances within the specified CIDR block can access the Internet or external networks by using SNAT. When you add an SNAT entry to an Internet NAT gateway, if SnatIp is set to an EIP, the ECS instance uses the specified EIP to access the Internet. If SnatIp is set to multiple EIPs, the ECS instance randomly selects an EIP specified in the SnatIp parameter to access the Internet. You cannot specify this parameter and SourceVSwtichId at the same time. If SourceVSwitchId is specified, you cannot specify SourceCIDR. If SourceCIDR is specified, you cannot specify SourceVSwitchId.

source_v_switch_ids^Optional

source_v_switch_ids: typing.Union[IResolvable, typing.List[typing.Union[str, IResolvable]]]

• Type: typing.Union[ros_cdk_core.IResolvable, typing.List[typing.Union[str, ros_cdk_core.IResolvable]]]

Property sourceVSwitchIds: The ID of the VSwitch to access the Internet.

When updating this list parameter, a new item will lead to a creation of new Snat Entry with latest properties, a removed item will lead to a deletion of the attached SnatEntry
