| === Begin SRU Template === | |
| [Impact] | |
| Support for configuration of IPV6 addresses on the primary network | |
| interface in EC2 changed behavior of the automatic network configuration. | |
| This changed behavior in 2 ways: | |
| a.) Instances with only a private ipv4 address would not get *any* ipv4 | |
| address. | |
| b.) Instances with multiple NICs attached at boot would get all NICs | |
| configured. Previously only the primary network interface would be | |
| configured by cloud-init. | |
| 'b' is not necessarily a bug for Artful. A new release can bring new | |
| behavior. However, the change of behavior was not intended and not desired | |
| for an SRU. In an effort to keep this behavior consistent across 16.04+ | |
| we will be changing the behavior of Artful to only configure the primary | |
| network interface. | |
| [Test Case] | |
| To verify this code is fixed for all cases involved: | |
| 1. Verify that instances without public ipv4 get an ipv4 address. | |
| * Launch an instance on EC2 without a public IPV4 address. | |
| * Verify the instance has its Ipv4 address configured via ssh and | |
| checking 'ip' output. | |
| 2. Verify no regression is done to public systems. | |
| * Launch an instance on EC2 with a public IPV4 address. | |
| * Verify the instance has its ipv4 address configured. | |
| 3. Verify only the primary NIC is configured (17.10 only) | |
| * Launch an instance on EC2 with multiple nics configured. | |
| * Verify that only the primary nic has configuration by default. | |
| For each of the above, verification entails inspection of | |
| network config (/etc/network/interfaces.d/* or /etc/netplan/) | |
| and also network state ('ip a' output). | |
| [Regression Potential] | |
| Regression in this area of code is certainly limited to EC2, | |
| and most likely limited to network configuration. | |
| Complete failure would show itself as no networking at all and | |
| a WARNING or stack trace on the console logs. | |
