Quickly and easily list hosts across multiple accounts and all regions. Saves you from having to go searching through accounts if you're looking for a specific instance.
The application is multi-threaded and should return results in 5 to 6 seconds depending on how many accounts and regions you have. To get better performance comment out regions that you aren't actively using.
usage: ec2list [-h] [-i INSTANCES] [-v] [-a] [-f FILTER]
optional arguments:
-h, --help show this help message and exit
-i INSTANCES, --instances INSTANCES
Comma-separated list of instances to filter results.
-v, --verbose Print all host metadata.
-a, --all List all hosts, even those that aren't running.
-f FILTER, --filter FILTER
key value filters to pass directly to command. Eg:
Name=instance-type,Value=m1.small
You must have a $HOME/.aws/config file setup with the proper credentials.
An example profile:
[profile production]
aws_access_key_id=AKIAFOO
aws_secret_access_key=grzOgbar
region=us-west-1
[profile staging]
aws_access_key_id=AKIAIFOO
aws_secret_access_key=BAYS232bar
region=us-west-1
You can test that the different profiles are active by running the aws cli tool
aws ec2 describe-instances --profile=production
aws ec2 describe-instances --profile=staging
The columns when run this way will always be predictable (unlike -v). Useful if you're using awk or other things.
$ ./list
i-7e15d971 stephen_test_001 10.0.0.100 54.183.84.15 m3.large production
i-7e15d971 stephen_test_002 10.0.0.100 54.183.84.16 m3.large staging
...
By default only running instances will be shown. Use the -a or --all flag to show all instances, even those that are stopped.
$ ./list -a
Verbose prints everything returned by ec2. The return values are unordered.
./list -v
i-7e15d971:
Monitoring: {"State": "disabled"}
PublicDnsName: ec2-54-131-88-95.us-west-2.compute.amazonaws.com
RootDeviceType: ebs
State: {"Code": 16, "Name": "running"}
EbsOptimized: False
...
i-bba5d6e6:
Monitoring: {"State": "disabled"}
PublicDnsName: ec2-54-210-162-78.us-west-1.compute.amazonaws.com
RootDeviceType: ebs
State: {"Code": 16, "Name": "running"}
EbsOptimized: False
...
To easily filter instances by instance id, they can be passed as a comma-separated list with the -i or --instances flag.
./list -i i-bba5d6e6,i-cad1b0c2,i-afa406f2
Note that the filters arg allows you to pass filters down directory to the underlying aws ec2 command. See the ec2 api for information on the types of filtering you can do.
