Currently the fencing id is set statically in a PodTemplate annotation.
With this patch we add support to parse a template from the annotation
`fencing/id-template`, in order to calculate dynamically the fencing id
based on the node name.
The template itself should expect as input only one argument, the node
name. For example, if a user specifies the annotation:
fencing/id-template: {{ . | lower }}
it will output the node name in lower case. The template supports all
sprig functions of the go-template. The precedence of the fencing id
calculation goes as:
1. If the fencing/id annotation in the node exists, then the fencing id
will be the value of the annotation.
2. If the fencing/id annotation in the PodTemplate exists, then the
fencing id will be the value of the annotation.
3. If the fencing/id-template annotation in the PodTemplate exists, then
the value will be calculated based on this template with input the
node name.
4. The fencing id will equal to the node name.
This patch includes a bump of the Go version, since Go 1.18 does not
support the sprig functions with the text/template.

I am open to upgrade also to a later version of Go, e.g., the latest. |
