Hello @ankita m ,
in general (Open source) containers need some configuration (like volume binding, opening ports, supplying environment variables, secrets etc.).
In Azure IoT Edge, this is handled in Container Create Options.
An example (with InfluxDB and Grafana) is seen here.
Can you show the Container Create options of the Apache Nifi container?
Extra, where do you need the certificate for? Is it wise to expose this in blob storage? Is this a cloud blob storage? If so, where are the credentials kept?
Check out the NIFI settings. Is it possible to store the certificate on disk in a folder, available for the volume and with the right environment variable?
