Hi All, Apologies if that’s not the best place for this…
I am testing the Debian 12 AMI (in eu-west-1 at least) and encountered a weird issue: $ curl http://instance-data/ curl: (6) Could not resolve host: instance-data The issue stem from resolv.conf lacking the “<region>.compute.internal” domain search and instead only has “.” After digging up I found out thoses images have been migrated to netplan + networkd and the default/generated netplan base configurated is lacking the required “dhcpv4-override: use-domains: true”. I tried to apply that change via cloud-init’s user-data with no luck, as far as I could see the “local” part of cloud-init is bringing the network up “manually”, then fetch ec2 metadata and then setup netplan .. but without using the user-data part of the metadata .. The lovely cherry on top of the cake is that the network brought up before netplan actually include the correct domain suffix and is able to resolve ‘instance-data’: 2023-08-25 14:57:06,175 - util.py[DEBUG]: Resolving URL: http://169.254.169.254 took 3.865 seconds 2023-08-25 14:57:06,175 - util.py[DEBUG]: Resolving URL: http://[fd00:ec2::254] took 0.000 seconds 2023-08-25 14:57:10,175 - util.py[DEBUG]: Resolving URL: http://instance-data.:8773 took 4.000 seconds 2023-08-25 14:57:10,175 - DataSourceEc2.py[DEBUG]: Removed the following from metadata urls: ['http://instance-data.:8773'] Regards, Benoit
