Hi,
I’m trying to get the value of .Task.Slot
into a container label (in Swarm).
This does not work (template variables are not expanded in label values):
redis:
image: redis
labels:
foo: "{{.Task.Slot}}"
There are existing labels, which contain that value (“3”) as a substring (docker.swarm.task.name=redis.3.fwgp1aipl82s86up9vyiidw5e
). In my use-case, I’m not able to parse it out. I would like to have a label which contain just the task slot.
Use-case:
I’m monitoring containers via Telegraf. I would like to use Service.Name+Task.Slot as unique identifier for the series. If I use existing unique label (for example docker.swarm.task.name
), Telegraf will create a new time-series every time someone makes a deploy.
It would be really ideal, if Swarm containers already had a label like that (com.docker.swarm.task.slot ?).
Any suggestions ?
