Issue Template

• Does your issue follow our Code of Conduct?

• Ensure you are up-to-date with master.

• Search existing issues.

• Part of the project with issues: (ie. Agogosml, Deployment, CLI)

• Indicate OS, version of Python (Note: Only Python 3.7 is currently supported.)

  • Include versions of tooling where appropriate (Terraform, Kubernetes, Docker, etc.)

• Steps of reproduce issue. Provide a link to a Github Gist or paste here if short.
  To reproduce use the generate command to generate the template and then look at the input reader and out put writer docker files. both of them will have paths as follows :

FROM ${CONTAINER_REG}agogosml:${AGOGOSML_TAG} as builder

There needs to be a "/" after ${CONTAINER_REG} . because of the path being incorrect, the Azure Devops build fails with the following message

ull access denied for *********.azurecr.ioagogosml, repository does not exist or may require 'docker login'

After adding "/" build is successful

I will submit PR for this as well.
