Pass a input variables to pipelines using custom Curl trigger


With Harness In addition to Triggers using Git providers, artifact providers, manifests, and cron scheduling, Harness includes Custom Triggers that you can use to run Pipelines via a platform-agnostic Webhook.

In this blog we will see how we can pass a input variable (note we will be passing custom variable declared as part of the pipeline not pipeline variables) to a pipeline with custom trigger curl command.

something like this

curl -X POST  -H 'content-type: application/json' --url '' -d '{"sample_key": "sample_value"}'

Here instead of {“sample_key”: “sample_key”} we can pass custom variable which we declare as part of the pipeline like atrtifact tag {“tag”: “stable-perl”} which can be provided as a runtime input in the pipeline.

Let’s see this working in the pipeline

Step 1 : Declare the variable as part of the pipeline, we will passing image tag : satble-perl in the curl trigger command therefor let’s declare a variable with relevant name as tag and value as <+trigger.payload.tag.toLowerCase()>

Step 2 : We can pass this declared variable as a runtime input with curl command

Step 3 : Finally let’s pass the image tag in the curl command as below

curl -X POST  -H 'content-type: application/json' --url '' -d '{"tag": "stable-perl"}'
