I'm trying to write a script that will delete all available volumes that are up for more than 1 hour.
So I took the line that filters the volumes by state
aws ec2 describe-volumes --filters Name=status,Values=available | jq '.Volumes[]'
And I tried to combine it with another query I have for filtering snapshots by time creation
aws ec2 describe-snapshots --owner self --output json | jq '.Snapshots[] | select(.StartTime < "'$(date --date='-1 month' '+%Y-%m-%d')'") | [.Description, .StartTime, .SnapshotId]'
So I combined this query but it does not return any volume
aws ec2 describe-volumes --filters Name=status,Values=available | jq '.Volumes[] | select(.CreateTime < "'$(date --date='-1 hour' '+%Y-%m-%d')'") | [.VolumeId]'
And another weird thing, if I replace CreateTime with blabla the query does not fail but returns me the volume
~ $ aws ec2 describe-volumes --filters Name=status,Values=available | jq '.Volumes[] | select(.blabla < "'$(date --date='-1 hour' '+%Y-%m-%d')'") | [.VolumeId]'
Found another way to do this
aws ec2 describe-volumes --filters Name=status,Values=available --query "Volumes[?(CreateTime<'$(date --date='-1 day' '+%Y-%m-%d')')].[VolumeId]" --output text
I have multiple aws accounts and i don't remember in which aws account this EC2 instance was created, is there any optimal way to figure out in very less time?
Note: i need to know account DNS name or Alias name.(Not account number)
If you have access to the instance you could use Instance metadata API:
[ec2-user ~]$ curl http://169.254.169.254/latest/dynamic/instance-identity/document
It returns json with accountId field.
If you configure AWS CLI for all account, then you can get the Account ID, ARN and user ID.
The script does the following.
Get the list of AWS configuration profile
Loop over all profile
Get a list of All Ec2 public IP address
print account info if IP matched and exit
RUN
./script.sh 52.x.x.x
script.sh
#!/bin/bash
INSTANCE_IP="${1}"
if [ -z "${INSTANCE_IP}" ]; then
echo "pls provide instance IP"
echo "./scipt.sh 54.x.x.x"
exit 1
fi
PROFILE_LIST=$(grep -o "\\[[^]]*]" < ~/.aws/credentials | tr -d "[]")
for PROFILE in $PROFILE_LIST; do
ALL_IPS=$(aws ec2 describe-instances --profile "${PROFILE}" --query "Reservations[].Instances[][PublicIpAddress]" --output text | tr '\r\n' ' ')
echo "looking against profile ${PROFILE}"
for IP in $ALL_IPS; do
if [ "${INSTANCE_IP}" == "${IP}" ]; then
echo "Instance IP matched in below account"
aws sts get-caller-identity
exit 0
fi
done
done
echo "seems like instance not belong to these profile"
echo "${PROFILE_LIST}"
exit 1
loop over accounts
loop over regions
also be aware of lightsail!
I came up with the following and helped me. I didn't exclude the regions that did not have lightsail
for region in `aws ec2 describe-regions --output text --query 'Regions[*].[RegionName]' --region eu-west-1` ; do \
echo $region; \
aws ec2 describe-network-interfaces --output text --filters Name=addresses.private-ip-address,Values="IPv4 address" --region $region ; \
aws lightsail get-instances --region eu-west-1 --output text --query 'instances[*].[name,publicIpAddress]' --region $region; \
done
I switch instances between different regions frequently and sometimes I forget to turn off my running instance from a different region. I couldn't find any way to see all the running instances on Amazon console.
Is there any way to display all the running instances regardless of region?
Nov 2021 Edit: AWS has recently launched the Amazon EC2 Global View with initial support for Instances, VPCs, Subnets, Security Groups and Volumes.
See the announcement or documentation for more details
A non-obvious GUI option is the Tag Editor in the Resource Groups console. Here you can find all instances across all regions, even if the instances were not tagged.
I don't think you can currently do this in the AWS GUI. But here is a way to list all your instances across all regions with the AWS CLI:
for region in `aws ec2 describe-regions --region us-east-1 --output text | cut -f4`
do
echo -e "\nListing Instances in region:'$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]
When pushing images to Amazon ECR, if the tag already exists within the repo the old image remains within the registry but goes in an untagged state.
So if i docker push image/haha:1.0.0 the second time i do this (provided that something changes) the first image gets untagged from AWS ECR.
Is there a way to safely clean up all the registries from untagged images?
You can delete all images in a single request, without loops:
IMAGES_TO_DELETE=$( aws ecr list-images --region $ECR_REGION --repository-name $ECR_REPO --filter "tagStatus=UNTAGGED" --query 'imageIds[*]' --output json )
aws ecr batch-delete-image --region $ECR_REGION --repository-name $ECR_REPO --image-ids "$IMAGES_TO_DELETE" || true
First it gets a list of images that are untagged, in json format:
[ {"imageDigest": "sha256:..."}, {"imageDigest": "sha256:..."}, ... ]
Then it sends that list to batch-image-delete.
The last || true is required to avoid an error code when there are no untagged images.
Now, that ECR support lifecycle policies (https://docs.aws.amazon.com/AmazonECR/latest/userguide/LifecyclePolicies.html) you can use it to delete the untagged images automatically.
Setting up a lifecycle policy preview using the console
Open the Amazon ECS console at https://console.aws.amazon.com/ecs/.
From the navigation bar, choose the region that contains the
repository on which to perform a lifecycle policy preview.
In the navigation pane, choose Repositories and select a repository.
On the All repositories: repository_name page, choose Dry-Run
Lifecycle Rules, Add.
Enter the following details for your lifecycle policy rule:
For Rule Priority, type a number for the rule priority.
For Rule Description, type a description for the lifecycle policy
rule.
For Image Status, choose either Tagged or Untagged.
If you specified Tagged for Image Status, then for Tag Prefix List,
you can optionally specify a list of image tags on which to take
action with your lifecycle policy. If you specified Untagged, this
field must be empty.
For Match criteria, choose values for Count Type, Count Number, and
Count Unit (if applicable).
Choose Save
Create additional lifecycle policy rules by repeating steps 5–7.
To run the lifecycle policy preview, choose Save and preview results.
Under Preview Image Results, review the impact of your lifecycle
policy preview.
If you are satisfied with the preview results, choose Apply as
lifecycle policy to create a lifecycle policy with the specified
rules.

I actually forged a one line solution using aws cli
aws ecr describe-repositories --output text | awk '{print $5}' | egrep -v '^$' | while read line; do repo=$(echo $line | sed -e "s/arn:aws:ecr.*\///g") ; aws ecr list-images --repository-name $repo --filter tagStatus=UNTAGGED --query 'imageIds[*]' --output text | while read imageId; do aws ecr batch-delete-image --repository-name $repo --image-ids imageDigest=$imageId; done; done
What it's doing is:
get all repositories
for each repository give me all images with tagStatus=UNTAGGED
for each image+repo issue a batch-delete-image
If you have JQ, you can use this version that is more robust by not relying on the changing text format and also more efficient as it batch deletes once per repository:
aws ecr describe-repositories \
| jq --raw-output .repositories[].repositoryName \
| while read repo; do
imageIds=$(aws ecr list-images --repository-name $repo --filter tagStatus=UNTAGGED --query 'imageIds[*]' --output json | jq -r '[.[].imageDigest] | map("imageDigest="+.) | join (" ")');
if [[ "$imageIds" == "" ]]; then continue; fi
aws ecr batch-delete-image --repository-name $repo --image-ids $imageIds;
done
This has been broken up into more lines for readability, so better put it into a function in your .bashrc, but you could of course stuff it into a single line:
aws ecr describe-repositories | jq --raw-output .repositories[].repositoryName | while read repo; do imageIds=$(aws ecr list-images --repository-name $repo --filter tagStatus=UNTAGGED --query 'imageIds[*]' --output json | jq -r '[.[].imageDigest] | map("imageDigest="+.) | join (" ")'); if [[ "$imageIds" == "" ]]; then continue; fi; aws ecr batch-delete-image --repository-name $repo --image-ids $imageIds; done
Setting a Lifecycle policy is definitely the best way of managing this. That being said - if you do have a bunch of images that you want to delete keep in mind that the max for batch-delete-images is 100. So you need to do this is for the number of untagged images is greater than 100:
IMAGES_TO_DELETE=$( aws ecr list-images --repository-name $ECR_REPO --filter "tagStatus=UNTAGGED" --query 'imageIds[0:100]' --output json )
echo $IMAGES_TO_DELETE | jq length # Gets the number of results
aws ecr batch-delete-image --repository-name $ECR_REPO --image-ids "$IMAGES_TO_DELETE" --profile qa || true
If you want to remove an untagged image from a repository you can simply create a JSON lifecycle policy and then use python to apply the JSON policy to the repo
In my case, I am applying the policy to all the ECR repositories that are there in ECR and I have created a "lifecyclepolicy.json" file in my current directory where I have added the lifecycle policy of ECR
Here is my python code:-
import os
import json
import boto3
def ecr_lifecycle(lifecycle_policy):
ecr_client = boto3.client('ecr')
repositories = []
describe_repo_paginator = ecr_client.get_paginator('describe_repositories')
for response_list_repopaginator in describe_repo_paginator.paginate():
for repo in response_list_repopaginator['repositories']:
repositories.append(repo['repositoryName'])
for repository in repositories:
response=ecr_client.put_lifecycle_policy(repositoryName=repository,
lifecyclePolicyText=json.dumps(lifecycle_policy))
return response
if __name__ == '__main__':
path = os.path.dirname(__file__)
json_file = open(os.path.join(path, 'lifecyclepolicy.json'))
data = json.load(json_file)
ecr_lifecycle(data)
If you want to see the JSON file:-
{
"rules": [
{
{
"rulePriority": 10,
"description": "Only keep untagged images for 7 days",
"selection": {
"tagStatus": "untagged",
"countType": "sinceImagePushed",
"countUnit": "days",
"countNumber": 7
}
"action": {
"type": "expire"
}
}
]
}
Base on #Ken J's anwer,
Here is a python script that will clean ALL your ECR:
#!/usr/bin/python3
import subprocess
import json
import os
# Based on: https://stackoverflow.com/questions/40949342/how-to-delete-untagged-images-from-aws-ecr-container-registry

p = subprocess.Popen(command, shell = False, stdout = subprocess.PIPE, stderr = subprocess.PIPE)
return [p.stdout.read().decode("utf-8"), p.stderr.read().decode("utf-8")]
command = "aws ecr describe-repositories --region " + region + " --output json".split(" ")
data = _runCommand(command)[0]
for i in json.loads(data)["repositories"]:
name = i["repositoryName"]
print(name)
command = ["aws", "ecr", "list-images", "--region", region, "--repository-name", name, "--filter", "tagStatus=UNTAGGED", "--query", 'imageIds[*]', "--output" , "json"]
data = _runCommand(command)[0]
command = ["aws", "ecr", "batch-delete-image", "--region", region, "--repository-name", name, "--image-ids",data]
data = _runCommand(command)[0]
print(data)
First Step -->
untaggedImages = aws ecr list-images --repository-name <your_repo_name> --filter "tagStatus=UNTAGGED" --query 'to_string(imageIds[*])' --output json""")
Second step -->
aws ecr batch-delete-image --repository-name <your_repo_name> --image-ids "$untaggedImages" || true """)
to_string function is required because the returned JSON won't be in string format, instead it will be as an Object.
