After I loaded the image, I am trying to do the next step of configuration.

2) Configure your InterSystems IRIS instance

  2a) Enable the /api/IAM web application
  2b) Enable the IAM user
  2c) Change the password for the IAM user

Do we need to change these settings in iris.cpf file? any inputs where we have to configure. I have IRIS 2019.1.1 installed in my machine.

Thank you, I am able to load the image after I switch to linux container in server-side.

Thanks for reply @Dimtriy, I am new to Docker. I have below info on my machine about docker and looks it is using Windows container. Let me know if anything needs to be changed.
