This script finds the internal IP addresses of multiple AWS datastores and uses credentials supplied by you to connect from your local machine. The point is to avoid having to manually connect to a jump host to reach your data. The script also provides hints for datastore names, usernames and database names, generated from the supplied credentials.
The supported datastores are:
- Redshift
- RDS postgresql
- RDS mysql
- ElastiCache redis (single node, replication group, clustered)
- InfluxDB
The script assumes it has access to the internal IPs of the clusters/datastores, which means you have to be in the same VPN.
The script assumes you have configured awscli for your account. Also needs dig, psql (postgresql client), mysql (mysql client), influx (influxdb client), redis-cli (redis client).
Create a virtualenv with the libs in requirements.txt.
