Managing AWS via Python

Question

I'm new to Python/Boto3.

I would like to manage AWS using python.

I'm unable to find details on all available python functions of methods to manage AWS.

Example:

import boto3

ebs=boto3.resource('ec2')
vols=ebs.volumes.all()
for vol in vols:
    print vol.id

The above code works well but I'm trying to understand what is id in 'vol.id 'is it attribute of vol ? and where to find all available attributes that are valid to go with 'print vol.*'

How do I know that in 'vols=ebs.volumes.all()' all() is valid to use with volumes and what other options are available ?

I have tried using boto3 documentation but struggling.

Any help on this would be greatly appreciated.

Cheers,

How to get type hinting to work so I can see the available method calls and return types. I'm using PyCharm — AD7

You need to understand AWS services/infra to understand each Boto3 functionality. For quick start, playing AWS CLI first before dig yourself into boto3 (when you have poor understanding of each parameters). — mootmoot

If you want to print all attributes associated with vol, try these code

import boto3

ebs = boto3.resource('ec2')
vols = ebs.volumes.all()

for vol in vols:
    print vol.__dict__

This will print all the properties associated with volume.

Hope it helps !!

It worked for me. Think you forgot to mention you needed snapshot id's in question

Just like an instance id the Volumes also have identifiers, so this line "print vol.id" is printing the list of volume identifiers(since in a loop). You can use this ID to look for the volume. For example in the console under EC2>> Volumes>> when to type the ID in search it provides you the volume details.

all() - as the doucmentation says "Creates an iterable resources in the collection". This is just getting the list of all available volumes corresponding to ebs(elastic block storage). Another example :volume.snapshots.all()

This displays all the snapshots associated with a particular volume.

Hope this helps...
