Hello everybody,

I just received the following bug report on cloud-init.

Does somebody have experience with secondarly elastic network interfaces ?

By the way, I have not yet uploaded cloud-init 7.5, since I still have problems

Have a nice day,

In Amazon Linux, additional interfaces (and sub interfaces) is handled by a script in /etc/dhcp/dhclient.d called ec2dhcp.sh. This is under an Apache 2.0 license (http://aws.amazon.com/apache2.0/) - this script is calling functions from /etc/sysconfig/network-scripts/ec2net-functions which is also under an Apache 2.0 license.

In essence, these scripts set up additional interfaces and routing tables with metrics and preferences to enable the additional interfaces. Thus far I have not included them in the base Debian AMIs. Time for a community vote: should we adopt these into the Debian AMIs to support the additional interfaces that you may add to your instances, or does this diverge from a base Debian AMI (as per discussions last month)? Are we comfortable with using these verbatim (given the DFSG compatible Apache 2.0 license)?

If we get a few people confirm they are happy wit this, then I'll look to include this into bootstrap-vz for the next time we generate new AMIs.
