templating: container command and args using string not []string

[shenshanyoumu]

command: '{{inputs.parameters.k8s_cmds}}', is like '['/bin/bash','-c']'

cannot unmarshal string into Go struct field Container.spec.templates.container.command of type []string

The error is correct. You gave it a string input, but command accepts a string array.

command: '['/bin/bash','-c']' is invalid, note the quotes around the array.
You would want command: ['/bin/bash','-c'].

Argo can't do that transformation for you; ultimately a template is still a YAML string and Argo would not know what you want to convert.

You could instead do, for instance:

command:
  - '{{inputs.parameters.k8s_cmd_part1}}'
  - '{{inputs.parameters.k8s_cmd_part2}}'

[shenshanyoumu]

yes I know it's hard to adapt. but variables {{inputs.parameters.k8s_cmds}} I don't know details. so can't expand like

command:
  - '{{inputs.parameters.k8s_cmd_part1}}'
  - '{{inputs.parameters.k8s_cmd_part2}}'

You need to change your inputs or otherwise parse the string yourself. Your current inputs are invalid.

I'm not sure what else I can tell you. That's not a bug, your inputs don't match the k8s schema.
