I have successfully containerized meltano in an LXD container via Juju.. and added my beginnings of a custom tap. One question.. the tap can only run if a proprietary program that I am given.. is open , connected.. and I do this manually in another LXD container... how can I let airflow know.. to queue up pipelines for execution.. and only if the application is running .. do I begin to attempt to run my pipeline?
