How to pass a file instead of a string on a bitbucket variable to a DockerImage?

We have a dockerImage with our automation framework solution. All that it requires is a json file with valid data.

We are calling our dockerImage from a pipe in our bitbucket, but we couldn't solve how to pass a file instead of a string.


  • Folder structure:
    • bitbucket-pipelines.yml


  • The docker image just run the following code.


Failed Solution attempt:

We thought in doing a cat filepath, and it works for way too small json file. As soon as it becomes bigger it fails -----> docker: Argument list too long



Any other suggesstion of how to pass a file + read it from inside a dockerImage code?

I suspect it just does not accept such a long value, but you don't need to, it is bad practice to pass such values. Instead I propose to pass actually a filename itself, and in javascript code you could read from a file.  Following this way you shouldn't have problems parsing it.
