Generic dockerfile with --context-param switch that contains spaces

[kevinrlewis]

In regards to this post: Generic Dockerfile with Talend

I'm curious if there is a way to have a context variable that contains spaces. Currently with that dockerfile, running a job with a context and specifying "hello world" as that context and printing that context in the job will print "hello. Is there a way to configure the dockerfile or the job to allow context variables with spaces?

Thank you.

Hi,

sorry, it is not clear - do you want context variable name with space (no) or context variable value with space(yes)?

Hi,

    I have tried the normal use case depicted in Mike's article and it was working fine. But I have not tried passing parameters with spaces.

    But when I checked some links, other docker users have overcome  the issue by passing as an array.

    Could you please try solution mentioned in above example and let us know whether you were able to resolve it?

Sorry for the confusion. Context variable value with space.

@nthampi I will try the solution in that post and get back to you. Thank you!

@nthampi I tried doing it that way locally but that solution doesn't work which I believe is because of the nested strings within the command. My main goal is to give the context values to a task definition. Example:

{
  "networkMode": "none",
  "containerDefinitions": [
    {
      "memory": 1024,
      "name": "testPrint",
      "image": "talend:testPrint-latest",
      "cpu": 1024
    },
    {
      "environment":
      [
          {
              "name": "ARGS",
              "value": "--context_param test=\"howdy from context\""
          }
      ]
    }
  ],
  "family": "talend-testPrint"
}

Where the environment contains the context variables within the ARGS value. So multiple "--context_param" equals multiple context variables/values. I'm thinking based on your previous answer if I could put an array in the value field or something similar.
