aggregate_instances_by_type

Aggregate EC2 instance information group by instance-type, platform and tenancy on each account

Preparation

This program uses aws-cli, so you first need to prepare standard credentiol and profile like ~/.aws/credentials and ~/.aws/config. Example:

$ cat ~/.aws/credentials
[default]
# Main Account: 123456789012
aws_access_key_id = ABCDEFGHIJKLMNOPQRST
aws_secret_access_key = abcdefghijklmnopqrstuvwxwzABCDEFGHIJKLMN

$ cat ~/.aws/config
[default]
output = json
region = us-east-1

[profile accountA]
role_arn = arn:aws:iam::111111111111:role/accountA_Admin
source_profile = default
region = us-east-1

[profile accountB]
role_arn = arn:aws:iam::222222222222:role/accountB_Admin
source_profile = default
region = us-east-1

[profile accountC]
role_arn = arn:aws:iam::333333333333:role/accountC_Admin
source_profile = default
region = us-east-1

Execution

Aggregate by account (mode: -m account)

Example:

# Fields: Region, Instance Type, Platform, Tenancy, Count
$ echo "accountA" | bash aggregate_instances_by_type.sh -m account
sa-east-1,c4.large,None,default,10
sa-east-1,m3.medium,None,default,9
sa-east-1,m4.large,None,default,1
sa-east-1,t2.medium,None,default,3
sa-east-1,t2.micro,None,default,9
sa-east-1,t2.small,None,default,3

Aggregate by region (mode: -m region)

Example:

$ cat profile.list
default
accountA
accountB
accountC

# Fields: Region, Instance Type, Platform, Tenancy, Count
$ cat profile.list | bash aggregate_instances_by_type.sh -m region
