Run a task against one server out of inventory -> like limit

[mikch06]

It should be possible to create a tasks and limit it against a single host out of inventory. If possible by Dropdown or just with the written hostname.

• Now you have to run a playbook against the whole inventory.
• This is a feauture request more from system engineering side where we run a few small jobs against single hosts.

I have a workaround for this:

add the hosts line to your playbooks:

---
- name: Add logrotate configuration for docker logs
  hosts: "{{ target_hosts | default('all') }}"
  tasks:

and then add a survey variable in semaphore to your template.

Thx a lot! I know some workarounds but think it's too complicated for easy use and a genral inventory. But i'll give a try.

Came across this post. Was hoping to see if Semaphore finally added the Limit prompt similar to what AWX has.

Would love to see this feature in the future added to Semaphore, so playbooks don't have to be modified to add a simple prompt for the end user to run a task against a single machine.

"{{ target_hosts | default('all') }}"

How can we tell more than one host ?

[rwaffen]

it is possible to use a group or a host. but no list, thats true. if you refer to something like that

[mikch06]

My goal is still to have a dropdown or similar way to choose a single host out of a inventory. Just to run a single task (from template) against a single host. Typical to run a recap job. -> e.g. like --limit in ansible

Thx @gudge25, sorry just saw it now. I now how to handle it. But we like to handle a bunch of tasks to single or multiple hosts - spontaneously and also from not technical people. Thats why it's not too easy and we stay with other tools.

Still no solution?
