AWS-CLI: Ways to list down autoscalinggroups - amazon-web-services

Is there a way to list down the available AutoScalingGroups under an account and filter on top of it based on some tags?
I am looking for something like aws ecs list-clusters which gives list of ecs clusters.

Yes. You can use JMESPath syntax to filter the results of aws autoscaling describe-auto-scaling-groups command down to only those groups matching some tag's key/value pair. This uses the --query parameter, which is available for filtering on most AWS CLI commands.
Example to query by a single tag:
The example below filters results based on a tag where Key = 'Environment' and Value = 'Dev'.
aws autoscaling describe-auto-scaling-groups --query "AutoScalingGroups[? Tags[? (Key=='Environment') && Value=='Dev']]".AutoScalingGroupName
Example to query by multiple tags:
The example below filters results based on tags where Key = 'Environment' and Value = 'Dev', and Key = 'Name' and Value = 'MyValue'. This uses a pipe to query for the second tag on the resulting autoscaling groups of the query for the first tag.
aws autoscaling describe-auto-scaling-groups --query "AutoScalingGroups[? Tags[? (Key=='Environment') && Value=='Dev']] | [? Tags[? Key=='Name' && Value =='MyValue']]".AutoScalingGroupName
Further Reading
AWS Documentation - aws autoscaling describe-auto-scaling-groups
AWS Documentation - Controlling Command Output from the AWS Command Line Interface

The below AWS CLI command gives Auto Scaling Group with Tag having Key == Product and Value == test for a profile of account1
aws --profile account1 autoscaling describe-auto-scaling-groups \
--query 'AutoScalingGroups[?contains(Tags[?Key==`Product`].Value, `test`)].[AutoScalingGroupName]' --region eu-west-1 --output table

aws autoscaling describe-auto-scaling-groups \
--query AutoScalingGroups[].AutoScalingGroupName \
--filters \
"Name=tag:MyTagKey1,Values=MyTagValue1" \
"Name=tag:MyTagKey2,Values=MyTagValue2"

How can list AWS ENI's with a certain "Description" with AWS cli?

When I execute:
aws ec2 describe-network-interfaces --region=us-east-1 \
--query="NetworkInterfaces[*].[Description, NetworkInterfaceId]" \
--output text \
--filter 'Name=Description,Values=ELB*'
I get this error message:
An error occurred (InvalidParameterValue) when calling the DescribeNetworkInterfaces operation:
The filter 'Description' is invalid
I am trying to list my ENI's that have a description that starts with "ELB".
UPDATE: Thanks jordanm your suggestion has stopped the error message but I still think I doing something wrong with my filter option. If I execute:
aws ec2 describe-network-interfaces --region=us-east-1 \
--query="NetworkInterfaces[*].[Description, NetworkInterfaceId]" \
--output text | grep "^ELB"
I get results, but if I try to filter with --filter 'Name=Description,Values=ELB*' instead of | grep "^ELB" I do not get any results.
The following should get you ENI's whose description begin with 'EBS'
aws ec2 describe-network-interfaces --region=us-east-1 \
--query="NetworkInterfaces[?starts_with(Description, 'EBS')].[Description, NetworkInterfaceId]" \
--output text
You can change the literal 'EBS' to whatever value you want to check for in the description. If you want to do a check where the Description contains 'EBS' not just begins with it, you can use the following command
aws ec2 describe-network-interfaces --region=us-east-1 \
--query="NetworkInterfaces[?contains(Description, 'EBS')].[Description, NetworkInterfaceId]" \
--output text

Delete EBS Snapshot From Shell Script with Name and Date FIlter

Hi I want to delete EBS snapshot which is older then 30 days and want to filter out with pharse of it's name. Let's say the name contain word 'Manish'.
The name can be like that 'Manish-Ebs-snapshot' or EBS-Manish-snapshot or EBS-ManishFinal-Snapshot' like that.
I found out one command but it's collecting all the snapshot not a particular group of snapshot.
snapshots_to_delete=$(aws ec2 describe-snapshots --owner-ids xxxxxxxxxxxx --query 'Snapshots[?StartTime<=`2020-08-23`].SnapshotId' --output text)
echo "List of snapshots to delete: $snapshots_to_delete"
for snap in $snapshots_to_delete; do
aws ec2 delete-snapshot --snapshot-id $snap
done
can anyone help me with this above script how I can add name filter as well.
The field I want:
You can filter by description using *Manish*:
aws ec2 describe-snapshots --owner-ids xxxxxxxxx --filter Name=description,Values=*Manish* --query 'Snapshots[?StartTime<=`2020-08-23`].SnapshotId'
And by tag Name:
aws ec2 describe-snapshots --owner-ids xxxxxxxx --filter Name=tag:Name,Values=*Manish* --query 'Snapshots[?StartTime<=`2020-08-23`].SnapshotId'

How to see all running Amazon EC2 instances across all regions?

I switch instances between different regions frequently and sometimes I forget to turn off my running instance from a different region. I couldn't find any way to see all the running instances on Amazon console.
Is there any way to display all the running instances regardless of region?
Nov 2021 Edit: AWS has recently launched the Amazon EC2 Global View with initial support for Instances, VPCs, Subnets, Security Groups and Volumes.
See the announcement or documentation for more details
A non-obvious GUI option is the Tag Editor in the Resource Groups console. Here you can find all instances across all regions, even if the instances were not tagged.
I don't think you can currently do this in the AWS GUI. But here is a way to list all your instances across all regions with the AWS CLI:
for region in `aws ec2 describe-regions --region us-east-1 --output text | cut -f4`
do
echo -e "\nListing Instances in region:'$region'..."
aws ec2 describe-instances --region $region
done
Taken from here (If you want to see full discussion)
Also, if you're getting a
You must specify a region. You can also configure your region by running "aws configure"
You can do so with aws configure set region us-east-1, thanks #Sabuncu for the comment.
Update
Now (in 2019) the cut command should be applied on the 4th field: cut -f4
In Console
Go to VPC dashboard https://console.aws.amazon.com/vpc/home and click on Running instances -> See all regions.
In CLI
Add this for example to .bashrc. Reload it source ~/.bashrc, and run it
Note: Except for aws CLI you need to have jq installed
function aws.print-all-instances() {
REGIONS=`aws ec2 describe-regions --region us-east-1 --output text --query Regions[*].[RegionName]`
for REGION in $REGIONS
do
echo -e "\nInstances in '$REGION'..";
aws ec2 describe-instances --region $REGION | \
jq '.Reservations[].Instances[] | "EC2: \(.InstanceId): \(.State.Name)"'
done
}
Example output:
$ aws.print-all-instances
Listing Instances in region: 'eu-north-1'..
"EC2: i-0548d1de00c39f923: terminated"
"EC2: i-0fadd093234a1c21d: running"
Listing Instances in region: 'ap-south-1'..
Listing Instances in region: 'eu-west-3'..
Listing Instances in region: 'eu-west-2'..
Listing Instances in region: 'eu-west-1'..
Listing Instances in region: 'ap-northeast-2'..
Listing Instances in region: 'ap-northeast-1'..
Listing Instances in region: 'sa-east-1'..
Listing Instances in region: 'ca-central-1'..
Listing Instances in region: 'ap-southeast-1'..
Listing Instances in region: 'ap-southeast-2'..
Listing Instances in region: 'eu-central-1'..
Listing Instances in region: 'us-east-1'..
Listing Instances in region: 'us-east-2'..
Listing Instances in region: 'us-west-1'..
Listing Instances in region: 'us-west-2'..
From VPC Dashboard:
First go to VPC Dashboard
Then find Running instances and expand see all regions. Here you can find all the running instances of all region:
From EC2 Global view:
Also you can use AWS EC2 Global View to watch Resource summary
and Resource counts per Region.
#imTachu solution works well. To do this via the AWS console...
AWS console
Services
Networking & Content Delivery
VPC
Look for a block named "Running Instances", this will show you the current region
Click the "See all regions" link underneath
Every time you create a resource, tag it with a name and now you can use Resource Groups to find all types of resources with a name tag across all regions.
After reading through all the solutions and trying bunch of stuff, the one that worked for me was-
List item
Go to Resource Group
Tag Editor
Select All Regions
Select EC2 Instance in resource type
Click Search Resources
Based on imTachus answer but less verbose, plus faster. You need to have jq and aws-cli installed.
set +m
for region in $(aws ec2 describe-regions --query "Regions[*].[RegionName]" --output text); do
aws ec2 describe-instances --region "$region" | jq ".Reservations[].Instances[] | {type: .InstanceType, state: .State.Name, tags: .Tags, zone: .Placement.AvailabilityZone}" &
done; wait; set -m
The script runs the aws ec2 describe-instances in parallel for each region (now 15!) and extracts only the relevant bits (state, tags, availability zone) from the json output. The set +m is needed so the background processes don't report when starting/ending.
Example output:
{
"type": "t2.micro",
"state": "stopped",
"tags": [
{
"Key": "Name",
"Value": "MyEc2WebServer"
},
],
"zone": "eu-central-1b"
}
You can run DescribeInstances() across all regions.
Additionally, you can:
Automate it through Lambda and Cloud watch.
Create api endpoint using Lambda and api gateway and use it in your code
A sample in NodeJS:
Create and array of regions (endpoints). [can also use AWS describeRegions() ]
var regionNames = ['us-west-1', 'us-west-2', 'us-east-1', 'eu-west-1', 'eu-central-1', 'sa-east-1', 'ap-southeast-1', 'ap-southeast-2', 'ap-northeast-1', 'ap-northeast-2'];
regionNames.forEach(function(region) {
getInstances(region);
});
Then, in getInstances function, DescribeInstances() can be
called.
function getInstances(region) {
EC2.describeInstances(params, function(err, data) {
if (err) return console.log("Error connecting to AWS, No Such Instance Found!");
data.Reservations.forEach(function(reservation) {
//do any operation intended
});
}
And Off Course, feel free to use ES6 and above.
I wrote a lambda function to get you all the instances in any state [running, stopped] and from any regions, will also give details about instance type and various other parameters.
The Script runs across all AWS regions and calls DescribeInstances(), to get the instances.
You just need to create a lambda function with run-time nodejs.
You can even create API out of it and use it as and when required.
Additionally, You can see AWS official Docs For DescribeInstances to explore many more options.
A quick bash oneliner command to print all the instance IDs in all regions:
$ aws ec2 describe-regions --query "Regions[].{Name:RegionName}" --output text |xargs -I {} aws ec2 describe-instances --query Reservations[*].Instances[*].[InstanceId] --output text --region {}
# Example output
i-012344b918d75abcd
i-0156780dad25fefgh
i-0490122cfee84ijkl
...
My script below, based on various tips from this post and elsewhere. The script is easier to follow (for me at least) than the long command lines.
The script assumes credential profile(s) are stored in file ~/.aws/credentials looking something like:
[default]
aws_access_key_id = foobar
aws_secret_access_key = foobar
[work]
aws_access_key_id = foobar
aws_secret_access_key = foobar

AWS has recently launched the Amazon EC2 Global View with initial support for Instances, VPCs, Subnets, Security Groups, and Volumes.
To see all running instances go to EC2 or VPC console and click EC2 Global View in the top left corner.
Then click on Global Search tab and filter by Resource type and select Instance. Unfortunately, this will show instances in all states:
pending
running
stopping
stopped
shutting-down
terminated
I created an open-source script that helps you to list all AWS instances. https://github.com/Appnroll/aws-ec2-instances
That's a part of the script that lists the instances for one profile recording them into an postgreSQL database with using jq for json parsing:
DATABASE="aws_instances"
TABLE_NAME="aws_ec2"
SAVED_FIELDS="state, name, type, instance_id, public_ip, launch_time, region, profile, publicdnsname"
# collects the regions to display them in the end of script
REGIONS_WITH_INSTANCES=""
for region in `aws ec2 describe-regions --output text | cut -f3`
do
# this mappping depends on describe-instances command output
INSTANCE_ATTRIBUTES="{
state: .State.Name,
name: .KeyName, type: .InstanceType,
instance_id: .InstanceId,
public_ip: .NetworkInterfaces[0].Association.PublicIp,
launch_time: .LaunchTime,
\"region\": \"$region\",
\"profile\": \"$AWS_PROFILE\",
publicdnsname: .PublicDnsName
}"
echo -e "\nListing AWS EC2 Instances in region:'$region'..."
JSON=".Reservations[] | ( .Instances[] | $INSTANCE_ATTRIBUTES)"
INSTANCE_JSON=$(aws ec2 describe-instances --region $region)
if echo $INSTANCE_JSON | jq empty; then
# "Parsed JSON successfully and got something other than false/null"
OUT="$(echo $INSTANCE_JSON | jq $JSON)"
# check if empty
if [[ ! -z "$OUT" ]] then
for row in $(echo "${OUT}" | jq -c "." ); do
psql -c "INSERT INTO $TABLE_NAME($SAVED_FIELDS) SELECT $SAVED_FIELDS from json_populate_record(NULL::$TABLE_NAME, '${row}') ON CONFLICT (instance_id)
DO UPDATE
SET state = EXCLUDED.state,
name = EXCLUDED.name,
type = EXCLUDED.type,
launch_time = EXCLUDED.launch_time,
public_ip = EXCLUDED.public_ip,
profile = EXCLUDED.profile,
region = EXCLUDED.region,
publicdnsname = EXCLUDED.publicdnsname
" -d $DATABASE
done
REGIONS_WITH_INSTANCES+="\n$region"
else
echo "No instances"
fi
else
echo "Failed to parse JSON, or got false/null"
fi
done
To run jobs in parallel and use multiple profiles use this script.
#!/bin/bash
for i in profile1 profile2
do
OWNER_ID=`aws iam get-user --profile $i --output text | awk -F ':' '{print $5}'`
tput setaf 2;echo "Profile : $i";tput sgr0
tput setaf 2;echo "OwnerID : $OWNER_ID";tput sgr0
for region in `aws --profile $i ec2 describe-regions --output text | cut -f4`
do
tput setaf 1;echo "Listing Instances in region $region";tput sgr0
aws ec2 describe-instances --query 'Reservations[*].Instances[*].[Tags[?Key==`Name`].Value , InstanceId]' --profile $i --region $region --output text
done &
done
wait
Screenshot:
Not sure how long this option's been here, but you can see a global view of everything by searching for EC2 Global View
https://console.aws.amazon.com/ec2globalview/home#
Using bash-my-aws:
region-each instances
Based on #hansaplast code I created Windows friendly version that supports multiple profiles as an argument. Just save that file as cmd or bat file. You also need to have jq command.
#echo off
setlocal enableDelayedExpansion
set PROFILE=%1
IF "%1"=="" (SET PROFILE=default)
echo checkin instances in all regions for %PROFILE% account
FOR /F "tokens=* USEBACKQ" %%F IN (`aws ec2 describe-regions --query Regions[*].[RegionName] --output text --profile %PROFILE%`) DO (
echo === region: %%F
aws ec2 describe-instances --region %%F --profile %PROFILE%| jq ".Reservations[].Instances[] | {type: .InstanceType, state: .State.Name, tags: .Tags, zone: .Placement.AvailabilityZone}"
)
You may use cli tool designed for enumerating cloud resources (cross-region and cross-accounts scan) - https://github.com/scopely-devops/skew
After short configuration you may use the following code for list all instances in all US AWS regions (assuming 123456789012 is your AWS account number).
from skew import scan
arn = scan('arn:aws:ec2:us-*:123456789012:instance/*')
for resource in arn:
print(resource.data)
Good tool to CRUD AWS resources. Find [EC2|RDS|IAM..] in all regions. There can do operations (stop|run|terminate) on filters results.
python3 awsconsole.py ec2 all // return list of all instances
python3 awsconsole.py ec2 all -r eu-west-1
python3 awsconsole.py ec2 find -i i-0552e09b7a54fa2cf --[terminate|start|stop]

How to get the InstanceID using the PublicDnsName?

With the AWS CLI, given a PublicDnsName, how can I get the InstanceID? I tried
aws ec2 describe-instances --filters 'Name=publicdnsname,Values=ec2....
but it complains that
publicdnsname is not a valid filter
It is dns-name
aws ec2 describe-instances --filters "Name=dns-name,Values=ec2-xxxxx.compute-1.amazonaws.com" --query 'Reservations[*].Instances[*].InstanceId' --output text
Output
i-00123458ca3fa2c4f
The valid filters are listed in the docs.
To filter by public DNS name the filter name you should use is: dns-name

aws cli: How can I query list values?

The aws cli has a --query option, which allows you to select only some information.
For an example, I am interested in getting just the Security group name from ec2 describe-instances.
If I run:
aws ec2 describe-instances --output text --query 'Reservations[*].Instances[*].[InstanceId,InstanceType,SecurityGroups]
my output looks like:
i-xxxxxxx m1.type [{u'GroupName': 'groupName', u'GroupId': 'sg-xxxxx'}]
I can also access elements of the list using an index:
aws ec2 describe-instances --output text --query 'Reservations[*].Instances[*].[InstanceId,InstanceType,Tags[0].Value,Tags[0].Name]
Is it possible to query tags so that instead of Tag[0] I search for a Tag where the name is specified?
As of 1.3.0, you can now query that information like this:
--query 'Reservations[*].Instances[*].Tags[?Key==`<keyname>`].Value[]'
So where you have this:
"Tags" : [
{
"Value" : "webserver01",
"Key" : "InstanceName"
},
you'd want to do this:
aws ec2 describe-instances --query 'Reservations[*].Instances[*].Tags[?Key==`InstanceName`].Value[]'
What you probably want to use is the --filters option:
aws ec2 describe-instances --output text --filters "Name=tag-key, Values=SecurityGroups, Name=tag-value, Values=Foo" --region us-east-1
You can change the filters around to "query" for the exact field you're looking for.
checkout this slideshare from the Atlanta AWS meetup group's talk on the new AWS CLI for more examples
This way works for me: (this only works in version 1.3.0 and above)
aws ec2 describe-instances --query 'Reservations[*].Instances[*].[InstanceId, Tags[?Key==`Name`].Value[*]]'
select security_groups from aws.aws_ec2_instance;
> select security_groups from aws.aws_ec2_instance limit 1;
+---------------------------------------------------------------------------------------------------------------------------------+
| security_groups |
+---------------------------------------------------------------------------------------------------------------------------------+
| [{"GroupId":"sg-xxxx","GroupName":"xxxx"},{"GroupId":"sg-xxxxxx","GroupName":"xxxx"}] |
+---------------------------------------------------------------------------------------------------------------------------------+
This will just list out the security groups for your instances.
You can also use
select security_groups from aws.aws_ec2_instance where instance_id = 'i-xxxxxx';
