CNI IPAM Driver

Infoblox IPAM Driver for CNI

cni-infoblox is an IPAM driver for CNI that interfaces with Infoblox to provide IP Address Management service. CNI is the generic plugin-based networking layer for supporting container runtime environments.

For a detailed description of the driver, including a step by step deployment example, refer to the community blog on the Infoblox website: CNI Networking and IPAM.

Prerequisite

  • A NIOS DDI Appliance with cloud automation License.

To use the plugin, you need access to the Infoblox DDI product. For evaluation purposes, you can download a virtual version of the product from the Infoblox Download Center and you can also assign temp license by login into the Infoblox DDI appliance console with this command set temp_license. Alternatively, if you are an existing Infoblox customer, you can download it from the support site.

Refer to CONFIG.md for details on vNIOS configuration.

  • Infoblox WAPI user should have the following permissions
Permission         Type	Resource	                            Resource Type        permission

Configuring Supported container runtimes

Refer to the following links to configure each container runtime to use infoblox cni plugin:

  • Kubernetes - README-K8S.md
  • Rocket - With the Rocket(rkt), deallocate of IP does not work. Until rocket has latest cni, the infoblox plugin support will not be provided. Still configuring rocket to use infoblox cni plugin can be read at README-rkt.md

Development

  • Build - For dependencies and build instructions, refer to BUILD.md .

Limitations

  • Doesn't have Infoblox DNS support.
  • For one Kubernetes deployment only one Infoblox Network view can be used.

Troubleshoot

If you get a message Cloud Network Automation License not available or Infoblox WAPI user not having sufficient permissions. in the cni-infoblox-daemon log then you have to check for the "Cloud Network Automation License" has applied and also check for sufficient permissions for the "Infoblox WAPI User" as given in the prerequisite.
