In daily use, there is often a sequence of services that is included in each of my workflows. For example, this can be copying data into my environment, or pre-processing before the actual calculation starts. However, at the moment I have to write these services every time into my workflow.
It would be nice if I could outsource these steps to a macro. Similar to the service.yaml
there would then be a macro.yaml
containing predefined sequences of services (i.e. more or less small workflows). They also have inputs and outputs so that I can continue working with the results in my actual workflow.
For example, a macro.yaml
could look like this:
id: preparation
name: Preparation of data
inputs:
- id: "source"
var: "source"
outputs:
- id: "destination"
var: "destination"
actions:
- type: execute
service: download
inputs:
- id: "source"
value: "source"
outputs:
- id: "output"
var: downloadedData
- type: execute
service: preprocess
inputs:
- id: "input"
value: "downloadedData"
outputs:
- id: "output"
var: destination
This bundles the two services download and preprocess and makes them available as a macro preparation.
In my workflow I could then use it like this:
api: 4.6.0
actions:
- type: macro
macro: preparation
inputs:
- id: source
value: http://example.com/my-data
outputs:
- id: destination
var: preparedData
- type: execute
service: calculation
inputs:
- id: input
var: preparedData
outputs:
- id: output
var: outputDirectory
Can something like this be added to Steep?
There should be an option that makes the Docker runtime call docker pull
before docker run
if the image tag is latest
.
Throw an error if the configuration contains duplicate setup IDs
It should be possible to override SSH settings from the global configuration per setup.
I can define plugins to adjust the execution behavior. It is possible to define multiple plugins of the same type. For example I can define two processChainAdapter plugins A and B.
Currently their execution order is given by the definition order in the corresponding yaml file. This is an implicit definition and might change at any time in the future.
It would be nice to have an order
attribute for each plugins. Plugins with a larger order
are executed after plugins with a lower order
independently of their definition order in the yaml file.
Example:
- name: myPluginA
type: processChainAdapter
order: 2
scriptFile: myPluginA.kt
- name: myPluginB
type: processChainAdapter
order: 1
scriptFile: myPluginB.kt
In this case the plugin B should be executed before plugin A.
