SSH Tunnels

Convenience tool to create SSH tunnels to cluster applications on AWS.

Example cluster applications would be:

• Kafka

$ tunnels my-senza-stack 9092 odd-eu-central-1.myteam.example.org --region eu-central-1

Installation

$ sudo pip3 install --upgrade stups-ssh-tunnels

Connecting to a Cassandra cluster deployed with Senza:

$ piu odd-eu-west-1.myteam.example.org SSH tunnel to Cassandra for keyspace management
$ tunnels my-cassandra 9042 odd-eu-west-1.myteam.example.org --region eu-west-1
# open a new terminal
$ cqlsh 172.31.141.1 # take one seed IP printed by tunnels.py
