## on the AGGREGATOR:
DEMO_NAME = "MNIST"
fx workspace create --prefix ${DEMO_NAME} --template "keras_cnn_mnist"

# Optional:
# Change plan/data.yaml
# Check num of collaborators is right in plan/plan.yaml

FQDN=hostname --all-fqdns 
fx plan initialize -a ${FQDN}
fx workspace certify
fx aggregator generate-cert-request --fqdn ${FQDN}
fx aggregator certify --fqdn ${FQDN}

# Let's export the workspace onto the collaborators
fx workspace export


# NOTE: the export cmd will create a zip file. Choose your favourite
# way to share that file with all the collaborators.
# In my case, I used the scp cmd.


#-----------------------------------------------------------------------------------------------
## on the COLLABORATOR (assuming the zip file has been copied)
fx workspace import --archive ${DEMO_NAME}.zip

# Init the collaborators by specifying the same data_path/index as previously defined 
# within the plan/data.yaml (if changed)
fx collaborator generate-cert-request -d ${DATA_PATH} -n ${COL_NAME}


#-----------------------------------------------------------------------------------------------
# Move the zip file generated (name pattern similar to "col_${COL_NAME}_to_agg_cert_request.zip")
# into the cert/ dir within the aggregator workspace. 

## on the AGGREGATOR
fx collaborator certify --request-pkg cert/col_${COL}_to_agg_cert_request.zip


#-----------------------------------------------------------------------------------------------
# Now let's move the signed certificates back to the respective collaborators
# and import them
fx collaborator certify --import agg_to_col_${COL_NAME}_signed_cert.zip


#-----------------------------------------------------------------------------------------------
# Here we go with starting the Federation!
## on the AGGREGATOR
Fx aggregator start
 
## on the COLLABORATOR
Fx collaborator start -n ${COL_NAME}
