It is necesarry to install Docker and Cassandra, to facilitate the installation and deployment procedure for the HSS (Home Subscriber Server).

Install docker

sudo snap install docker   
sudo groupadd docker       
sudo adduser $USER docker
reboot

Install cassandra DB

cd mosaic5g/
docker ps    
docker run --name cassandra-docker -d -e CASSANDRA_CLUSTER_NAME="OAI HSS Cluster" \
      -e CASSANDRA_ENDPOINT_SNITCH=GossipingPropertyFileSnitch \
      mosaic5gecosys/cassandra-m5g:1.0   # Create a cassandra container for the HSS
docker exec -it cassandra-docker bash 
nodetool status                       
cqlsh --file ./oai_db.cql 172.17.0.2     # Install the oai_db database
exit
docker start cassandra-docker            # start the container

• The cassandra status and IP address (172.17.0.2).
• The container must be started every time the computer starts.
