| slawomir | hello! what is a best way to give an instance a random hostname? | 11:23 |
|---|---|---|
| slawomir | now i'm doing something like this: | 11:23 |
| slawomir | #!/bin/bash | 11:23 |
| slawomir | HOST=my-random-host-name-${RANDOM} | 11:23 |
| slawomir | DOMAIN=localdomain | 11:23 |
| slawomir | hostnamectl set-hostname ${HOST} | 11:23 |
| slawomir | sed -i "s/^preserve_hostname:.*/preserve_hostname: true" /etc/cloud/cloud.cfg | 11:23 |
| slawomir | sed -i "s/^127.0.0.1.*/127.0.1.1\t${HOST}.${DOMAIN} ${HOST}\n127.0.0.1\tlocalhost/" /etc/hosts | 11:23 |
| slawomir | i want to start using #cloud-config configuration | 11:23 |
| blackboxsw | slawomir (now gone) should probably be thinking about using jinja template header in cloud-config userdata like the following | 17:38 |
| blackboxsw | ## template: jinja | 17:38 |
| blackboxsw | #cloud-config | 17:38 |
| blackboxsw | {% set HN = 'myhost-' ~ cloud_name ~ '-' ~ region ~ '-' ~ range(1,100) | random %} | 17:38 |
| blackboxsw | hostname: {{ HN }} | 17:38 |
| blackboxsw | falcojr: holmanb aciba: 23.4 will be blocked by https://github.com/canonical/cloud-init/issues/4630. init-local timeframe before datasource is detected (in DataSourceNone case) we can't write network-config.json to /v/l/c/instance/network-config.json because the datasource is yet to be detected. This affects subiquity/autoinstall. I'm working a fix and should have a PR up within an hour | 17:40 |

| blackboxsw | I can reproduce this on live-server install images. dbungert heads up as you talked internally about this potential issue. | 17:40 |
| dbungert | blackboxsw: saw that, thanks! | 17:40 |
| blackboxsw | repeated msg: slawomir (now gone) should probably be thinking about using jinja template header in cloud-config userdata like the following | 17:56 |
| blackboxsw | 10:38 ## template: jinja | 17:56 |
| blackboxsw | 10:38 #cloud-config | 17:56 |
| blackboxsw | 10:38 {% set HN = 'myhost-' ~ cloud_name ~ '-' ~ region ~ '-' ~ range(1,100) | random %} | 17:56 |
| blackboxsw | 10:38 hostname: {{ HN }} | 17:56 |
| blackboxsw | meh missed it. will table that for random hostname for now | 17:56 |
