Python 3.x - Aws Boto3 Scripts

Development Principle

Getting Started

All scripts are written in Python 3.x and requires Boto3
Authentication is via credentials and profile you have configured in $HOME/.aws (Same files as AWS CLI )
Unless specified as 'Generic', script rely on dvclass and a custom CMDB file for making decisions easy.
All scripts will have help available by running -h

Scripts (Requires Custom CMDB)

albctl.py : Custom, list/status/detach/attach multiple ALB and instances.
dnsctl.py : Add/remove/update DNS record
elbctl.py : Custom, mange Classig ELB
dvsnaps.py : Cutom, manage Snapshot tasks. Requires my CMDB

Generic scripts ()

lb-whitelistcheck.py : Check if IP is whitelisted on ELB/ALB or print all SG rules attached to ALB/ELB
ec2instance.py : Generic, manage Ec2 instance stop/start
elbctlv1.py : Generic mange Classic ELB

Script details

lb-whitelistcheck.py

Accept ELB/ALB name as input along with profile and region (or Default and eu-west-1 used)
- Print all rules attached to ELB/ALB
- Check if specifies IP's are whitelisted or not, and if whitelisted Rule is displayed with SG name

./lb-whitelistcheck.py
usage: lb-whitelistcheck.py [-h] {alb,elb,albcheck,elbcheck} ...

  -z ZONEID, --zoneid ZONEID
                        Zone ID, defaults to vettomcqms ID
  --destzoneid DESTZONEID
                        Destination Zone ID for ELB only or if different
                        zoneid
  --health_check {True,False}
                        Evaluate health check, Default=False

Script to manage DNS record in vettomcqms.net by default or provide -z zoneid
to create in another zone.

Creating multiple alias record pointing to xyz.vettom.co.uk. Accept at command line or from file.

./dnsupdate.py add -s 123.vettom.co.uk abc.vettom.co.uk -d zyz.vettom.co.uk
