My need is to run drone build when create a new tag in Gitea.
I can see two options there in Drone documentation. Please find below:
When
when:
event: tag
branch: master
Trigger
trigger:
branch:
- master
ref:
include:
- refs/tags/**
Please explain the difference and suggest which option is good to take.
Drone has a concept of "Pipelines" and "Steps".
A pipeline is made up of one or more steps.
The "when" is called a condition and is used to limit step execution - i.e. a pipeline with 4 steps defined may only run 2 steps based on conditions set. - condition docs
Triggers are used to to limit whole pipeline execution - i.e. a pipeline may or may not run at all based on triggers set. - trigger docs
It sounds to me that your use case is better served by a trigger - i.e. only run this build if a tag is created.
