I am able to add a task in a job to run the testapi.py file which takes a simple string as input and send it to the flask app running inside the docker container.
But,
The task execution is throwing an error

Things I have done
I made sure that the start task(which runs the flask app) is executed by sudo user created by me (not _azbatch user), tasks inside the jobs are also executed by the same user.
I tested the same command executed by the task by doing ssh into the same node with the user login created by me and the command runs fine.
when I run the command from _azbatch it throws the same error.
I was able to configure the following setup,![azure batch _fail](https://user-images.githubusercontent.com/44601878/65148310-8d4ced80-da3d-11e9-8105-1ffd56277060.jpg)
