FAQs

How are node names generated?

In EC2

If we’re in EC2, we look for a Node tag/knob. If the Node tag/knob exists, our node name will be AWS_REGION-NODE_TAG_KNOB-INSTANCE_ID

If the node tag/knob doesn’t exist, we look for the Hostname tag/knob and set the node name to AWS_REGION-HOSTNAME_TAGKNOB.

If the Hostname tag/knob is missing we fail back to reading the output of hostname

Outside EC2

If we aren’t in EC2, we look for a /etc/knobs/Hostname file and use the contents of that - if there’s no knob file we use the output of hostname so we have at least something sane-ish.
