Retry a failed Workflow just from failed step/node

[bygui86]

Is it possible to retry a failed Workflow just from the step/node that failed?

For example I have a Workflow with following steps (in a dag):

1. build-code
2. test-code
3. build-container
4. deploy

For any reason, the build-container step fails... is it possible to retry the same Workflow starting directly from build-container step instead form the beginning?

That's exactly what the argo retry CLI command does. There are also flags like --node-field-selector and --restart-successful that you can use to select nodes to retry more specifically.

Thanks @terrytangyuan do you have also a link to the documentation about those flags?
what about the UI? no option to have same result from UI?
CLI is nice, but I cannot ask everybody to install and use it as sometimes they are not really technical people...

UI may not have all the functionalities yet. If you need a particular one, feel free to submit an issue

For posterity, #12022 was opened for this functionality in the UI. There is actually an older issue that it duplicated though, #10139

@terrytangyuan I found the documentation here but it's pretty short and not really intuitive...
--node-field-selector string selector of nodes to reset, eg: --node-field-selector inputs.paramaters.myparam.value=abc
so I have to specify again all inputs parameters?
is it not possible to take the parameters from the last run?

It's only used if you want to override your previously provided parameter values
