Condition based on the outputs of an upstream execution.
The condition returns false if the execution has no output. If the result is an empty string, a space, or false, the condition will also be considered as false.
yaml
type: "io.kestra.plugin.core.condition.ExecutionOutputs"The upstream flow_a must explicitly define its outputs
to be used in the ExecutionOutputs condition.
yaml
id: flow_a
namespace: company.team
inputs:
- id: user_value
type: STRING
defaults: hello
tasks:
- id: hello
type: io.kestra.plugin.core.debug.Return
format: "{{ inputs.user_value }}"
outputs:
- id: flow_a_output
type: STRING
value: "{{ outputs.hello.value }}"
The flow_condition_executionoutputs will run whenever flow_a finishes successfully
and returns an output matching the value 'hello':
yaml
id: flow_condition_executionoutputs
namespace: company.team
tasks:
- id: upstream_outputs
type: io.kestra.plugin.core.log.Log
message: hello from a downstream flow
triggers:
- id: condition_on_flow_execution_outputs
type: io.kestra.plugin.core.trigger.Flow
states:
- SUCCESS
conditions:
- type: io.kestra.plugin.core.condition.ExecutionOutputs
expression: "{{ trigger.outputs.flow_a_output == 'hello' }}"
