-h3. Running a pipeline with different parameters
-
-Notice that the pipeline definition explicitly specifies the Keep locator for the input:
-
-<notextile>
-<pre><code>...
- "do_hash":{
- "script_parameters":{
- "input": "887cd41e9c613463eab2f0d885c6dd96+83"
- },
- }
-...
-</code></pre>

-
-What if we want to run the pipeline on a different input block? One option is to define a new pipeline template, but would potentially result in clutter with many pipeline templates defined for one-off jobs. Instead, you can override values in the input of the component like this:
