Thanks for your efforts on this project.

There is some evidence that Amazon's json pages may have changed format today. Have you had experience with this?

Test program (foo.py):

#!/usr/bin/env python

from ec2instancespricing import ec2instancespricing

prices = ec2instancespricing.get_ec2_ondemand_instances_prices()

Results:

$ python foo.py
Traceback (most recent call last):
File "foo.py", line 5, in
prices = ec2instancespricing.get_ec2_ondemand_instances_prices()
File ".../libs/ec2instancespricing/ec2instancespricing.py", line 456, in get_ec2_ondemand_instances_prices
instance_size = INSTANCE_SIZE_MAPPING[s["size"]]
KeyError: 'm1.small'

Just picking nits, but in addition to argparse and prettytables, I had to run easy_install demjson before running the python script.

Traceback:
File "./ec2instancespricing/ec2instancespricing.py", line 510, in get_ec2_instances_prices
region_name = JSON_NAME_TO_EC2_REGIONS_API[r["region"]]
KeyError: u'ap-south-1'

Fixed by adding new entity to map

• "ap-south-1": "ap-south-1",

It looks like the "g2.2xlarge" instance type is missing.

Need to add Canada and London

"ca-central-1": "ca-central-1",

"eu-west-2": "eu-west-2",

I have installed pretty table but it is showing this error.

ImportError: No module named 'prettytable'

There's a new API that's available for some (but not ALL) services: http://docs.aws.amazon.com/awsaccountbilling/latest/aboutv2/price-changes.html. This script should slowly migrate to that set of APIs

Here's a module that's already using it: https://github.com/lashex/pyutu

We can't switch to that yet since this module also covers services that aren't available from the new API.

I would like to how to run this script is there any specific parameter args I need to run the script right now im just using python ec2instancespricing.py. However I'm getting this error when running the scripts

Traceback (most recent call last):

Missing an n here!

get_ec2_ondemand_instances_prices - to get the pricing of On-Demand instances
get_ec2_reserved_instances_prices - to get the pricing of reserved instances (in all utilization levels)
get_ec2_spot_instances_prices - to get the pricing of spot instances

I'm runnning the script like this:

./ec2instancespricing.py --type ondemand --filter-region us-east-1 --filter-type 'm3.2xlarge' --filter-os-type 'linux' --format json

And I'm getting this error:

Traceback (most recent call last):
  File "./ec2instancespricing.py", line 527, in <module>
    print json.dumps(data)
NameError: name 'json' is not defined

The problem is that, when the json module was changed, it was forgotten to change this line.

It would be awesome if this were in pip.

Hynek wrote a nice guide.

If I had some time, I'd do this in my fork.

Thanks for creating this.

Hello

I am getting an error:

KeyError: u'ap-east-1'

when trying to run the CLI

If you're willing to pull in botocore,

import botocore.session

sess = botocore.session.Session()
available_types = sess.get_service_model('ec2').shape_for('InstanceType').enum

generates the instance type list at runtime; wouldn't be hard to work that in instead.

How do you feel about that, philosophically?

Hi, I am trying to run this code using python but it is not running? Can you please tell me how I can run this? Thanks.

If i want to print_r i get everytime

Undefined index: m1.small

With the new reservation pricing scheme they've updated it all again

haven't found the json files yet but here are the .js versions

https://a0.awsstatic.com/pricing/1/ec2/linux-od.min.js

https://a0.awsstatic.com/pricing/1/ec2/previous-generation/ri-v2/linux-unix-shared.min.js

you need to pull off the callback( ... ); bit - however still not parsing as son

Hi,

It would be great if you could specify what license this code is released under. MIT, BSD or Apache would be ideal. Otherwise no one is able to legally use or extend this code!

Thanks

Example t1.micro us-east ondemand is missing.

I'm looking for the prices for ondemand, us-east-1, linux, m3.2xlarge. In the page, it says that the price is $0.560:

But when I run the script like this:

./ec2instancespricing.py --type ondemand --filter-region us-east-1 --filter-type 'm3.2xlarge' --filter-os-type 'linux' --format json

The output is:

{"regions": [{"region": "us-east-1", "instanceTypes": [{"os": "linux", "price": 0.9, "type": "m3.2xlarge"}]}], "config": {"currency": "USD", "unit": "perhr"}}

I think the problem is that the API may be deprecated. If you make a request to http://aws.amazon.com/ec2/pricing/pricing-on-demand-instances.json, you will see that it redirects to a deprecated API.

Hi,

Thanks a lot for writing a very useful tool!

As the title says, the url http://aws.amazon.com/ec2/pricing/json/linux-od.json now redirects to https://a0.awsstatic.com/pricing/1/deprecated/ec2/linux-od.json ?

On the ec2 pricing page, it uses something like for ec2 pricing data:

https://a0.awsstatic.com/pricing/1.0.19/ec2/linux-od.min.js

Maybe it's time to update to the new formats of pricing data for ec2?

Thanks a lot,

Heling

I tried to pull reserved instance information, but the region eu-central-1 for example is missing. We even have more eu- regions. but it seems to only pull eu-west-1.

    iam already install pretty table but my terminal show this error:cannot import name 'PrettyTable' from partially initialized module 'prettytable' (most likely due to a circular import)
