set nodes hostname during provisioning

avatar
Explorer

Good day,

is it possible to set a hostname on per-node basis during cluster creation.

For example may I use something like:

masters-1 {
count: 1

instance: ${instances.m5x} {
tags {
group: master-1
}
hostname: master-1.example.com
}
worker-1 {
count: 1

instance: ${instances.t2l} {
tags {
group: workers
}
hostname: worker-1.example.com
}
worker-2 {
count: 1

instance: ${instances.t2xl} {
tags {
group: workers
}
hostname: worker-2.example.com
}

 

I can not come up with a way to set up predefined hostnames for every node in director. In the past I've used terraform and chef for provisioning and it was obvious how to set hostname, create /etc/hosts file and etc.

Director doesn't have a built in way to specify hostnames like that. You may be able to achieve something like this through the use of bootstrapScripts which lets you run a script on the instance. Something to keep in mind, Director requires forward and reverse hostname resolutions in order to work correctly, so you will probably have to mess with DNS settings as well. This thread here may be of help.
