[00:11] Hi Chad, thanks for your prompt response. So for centos7 specifically, I wouldn't be able to install any cloud-init version later that 19.4? [12:46] Hello [12:48] How can we use environment variable in cloud config for AWS ec2 instance Ubuntu OS [15:04] world - i do have novice question? i wanted to create a centos cloud-init enable template to use dhcp. it seems straight forward. yum install cloud-init && systemctl enable cloud-init && systemctl restart cloud-init. am i missing something? [15:10] anyone ? [15:16] _leaving quietly_ [17:49] I need some help please fixing up the tests for https://github.com/canonical/cloud-init/pull/1278 thanks. [17:49] Pull 1278 in canonical/cloud-init "systemctl location" [Open] [22:12] Yiyi: sorry missed this prior ping. There are a number of python3-only constructs in the code that will likely cause you issues running later cloud-init than 19.4 on centos7. Certainly the stdlib 'typing' module use that we introduced in 2020 in cloud-int I think (would would be cloud-init version 20.3 maybe). There also python 3.5-isms as far as iterable unpacking that would just plain break on python 2.7 . [22:13] So expectation is grabbing latest cloud-init and trying to run on 2.7 will likely cause lots of pain in various configuration modules
