cloud-nuke
This repo contains a CLI tool to delete all resources . cloud-nuke was created for situations when you might have an account you use for testing and need to clean up leftover resources so you're not charged for them. Also great for cleaning out accounts with redundant resources. Also great for removing unnecessary defaults like default VPCs and permissive ingress/egress rules in default security groups.
In addition, cloud-nuke offers non-destructive inspecting functionality that can either be called via the command-line interface, or consumed as library methods, for scripting purposes.
The currently supported functionality includes:

WARNING: The RDS APIs also interact with neptune and document db resources. Running
cloud-nuke aws --resource-type rds
without a config file will remove any neptune and document db resources in the account.
NOTE: AWS Backup Resource: Resources (such as AMIs) created by AWS Backup, while owned by your AWS account, are managed specifically by AWS Backup and cannot be deleted through standard APIs calls for that resource. These resources are tagged by AWS Backup and are filtered out so that
cloud-nuke
does not fail when trying to delete resources it cannot delete.
BEWARE!
When executed as cloud-nuke aws
, this tool is HIGHLY DESTRUCTIVE and deletes all resources! This mode should never
be used in a production environment!
When executed as cloud-nuke defaults-aws
, this tool deletes all DEFAULT VPCs and the default ingress/egress rule for
all default security groups. This should be used in production environments WITH CAUTION.
Telemetry
As of version v0.29.0
cloud-nuke sends telemetry back to Gruntwork to help us better prioritize bug fixes and feature
improvements. The following metrics are included:
- Command and Arguments
- Version Number
- Timestamps
- Resource Types
- Resource Counts
- A randomly generated Run ID
- AWS Account ID
We never collect
- IP Addresses
- Resource Names
Telemetry can be disabled entirely by setting the DISABLE_TELEMETRY
environment variable on the command line.
As an open source tool, you can see the exact statistics being collected by searching the code for
telemetry.TrackEvent(...)

Usage
Simply running cloud-nuke aws
will start the process of cleaning up your cloud account. You'll be shown a list of
resources that'll be deleted as well as a prompt to confirm before any deletion actually takes place.
In AWS, to delete only the default resources, run cloud-nuke defaults-aws
. This will remove the default VPCs in each
region, and will also revoke the ingress and egress rules associated with the default security group in each VPC. Note
that the default security group itself is unable to be deleted.
Nuke or inspect resources using AWS Profile
When using cloud-nuke aws
, or cloud-nuke inspect-aws
, you can pass in the AWS_PROFILE
env variable to target
resources in certain regions for a specific AWS account. For example the following command will nuke resources only
in ap-south-1
and ap-south-2
regions in the gruntwork-dev
AWS account:
AWS_PROFILE=gruntwork-dev cloud-nuke aws --region ap-south-1 --region ap-south-2
Similarly, the following command will inspect resources only in us-east-1
AWS_PROFILE=gruntwork-dev cloud-nuke inspect-aws --region us-east-1
Nuke or inspect resources in certain regions
When using cloud-nuke aws
, or cloud-nuke inspect-aws
, you can use the --region
flag to target resources in certain
regions. For example the following command will nuke resources only in ap-south-1
and ap-south-2
regions:
cloud-nuke aws --region ap-south-1 --region ap-south-2
Similarly, the following command will inspect resources only in us-east-1
cloud-nuke inspect-aws --region us-east-1
Including regions is available within:
cloud-nuke aws
cloud-nuke defaults-aws
cloud-nuke inspect-aws
Exclude resources in certain regions
When using cloud-nuke aws
or cloud-nuke inspect-aws
, you can use the --exclude-region
flag to exclude resources in
certain regions from being deleted or inspected. For example the following command does not nuke resources
in ap-south-1
and ap-south-2
regions:
cloud-nuke aws --exclude-region ap-south-1 --exclude-region ap-south-2
Similarly, the following command will not inspect resources in the us-west-1
region:
cloud-nuke inspect-aws --exclude-region us-west-1
--region
and --exclude-region
flags cannot be specified together i.e. they are mutually exclusive.
Excluding regions is available within:
cloud-nuke aws
cloud-nuke defaults-aws
cloud-nuke inspect-aws
Excluding Resources by Age
You can use the --older-than
flag to only nuke resources that were created before a certain period, the possible
values are all valid values for ParseDuration For example the following
command nukes resources that are at least one day old:
cloud-nuke aws --older-than 24h
Excluding resources by age is available within:
cloud-nuke aws
cloud-nuke inspect-aws
List supported resource types
You can use the --list-resource-types
flag to list resource types whose termination is currently supported:
cloud-nuke aws --list-resource-types
Listing supported resource types is available within:
cloud-nuke aws
cloud-nuke inspect-aws
Terminate or inspect specific resource types
If you want to target specific resource types (e.g ec2, ami, etc.) instead of all the supported resources you can
do so by specifying them through the --resource-type
flag:
cloud-nuke aws --resource-type ec2 --resource-type ami
will search and target only ec2
and ami
resources. The specified resource type should be a valid resource type
i.e. it should be present in the --list-resource-types
output. Using --resource-type
also speeds up search because
we are searching only for specific resource types.
Similarly, the following command will inspect only ec2 instances:
cloud-nuke inspect-aws --resource-type ec2
Specifying target resource types is available within:
cloud-nuke aws
cloud-nuke inspect-aws
Exclude terminating specific resource types
Just like you can select which resources to terminate using --resource-type
, you can select which resources to skip
using
--exclude-resource-type
flag:
cloud-nuke aws --exclude-resource-type s3 --exclude-resource-type ec2
This will terminate all resource types other than S3 and EC2.
--resource-type
and --exclude-resource-type
flags cannot be specified together i.e. they are mutually exclusive.
Specifying resource types to exclude is available within:
cloud-nuke aws
cloud-nuke inspect-aws
Dry run mode
If you want to check what resources are going to be targeted without actually terminating them, you can use the
--dry-run
flag
cloud-nuke aws --resource-type ec2 --dry-run
Dry run mode is only available within:
cloud-nuke aws
With Timeout
If you want to set up a timeout option for resources, limiting their execution to a specified duration for nuking, use the
--timeout
flag:
cloud-nuke aws --resource-type s3 --timeout 10m
This will attempt to nuke the specified resources within a 10-minute timeframe.
Protect Resources with cloud-nuke-after
Tag
By tagging resources with cloud-nuke-after
and specifying a future date in ISO 8601 format (e.g., 2024-07-09T00:00:00Z), you can ensure that these resources are protected from accidental or premature deletion until the specified date. This method helps to keep important resources intact until their designated expiration date.
Using cloud-nuke as a library
You can import cloud-nuke into other projects and use it as a library for programmatically inspecting and counting resources.
package main
import (
"context"
"fmt"
"time"
"github.com/aws/aws-sdk-go/aws"
nuke_aws "github.com/gruntwork-io/cloud-nuke/aws"
nuke_config "github.com/gruntwork-io/cloud-nuke/config"
"github.com/gruntwork-io/cloud-nuke/externalcreds"
)
func main() {
// You can scan multiple regions at once, or just pass a single region for speed
targetRegions := []string{"us-east-1", "us-west-1", "us-west-2"}
excludeRegions := []string{}
// You can simultaneously target multiple resource types as well
resourceTypes := []string{"ec2", "vpc"}
excludeResourceTypes := []string{}
// excludeAfter is parsed identically to the --older-than flag
excludeAfter := time.Now()
// an optional start time- can pass null if the filter is not required
includeAfter := time.Now().AddDate(-1, 0, 0)
// an optional execution timeout duration
timeout := time.Duration(10 * time.Second)
// Any custom settings you want
myCustomConfig := &aws.Config{}
myCustomConfig.WithMaxRetries(3)
myCustomConfig.WithLogLevel(aws.LogDebugWithRequestErrors)
// Optionally, set custom credentials
// myCustomConfig.WithCredentials()
// Be sure to set your config prior to calling any library methods such as NewQuery
externalcreds.Set(myCustomConfig)
// this config can be configured to add include/exclude rule to filter the resources- for all resources pass an empty struct
nukeConfig := nuke_config.Config{}
// NewQuery is a convenience method for configuring parameters you want to pass to your resource search
query, err := nuke_aws.NewQuery(
targetRegions,
excludeRegions,
resourceTypes,
excludeResourceTypes,
&excludeAfter,
&includeAfter,
false,
&timeout,
)
if err != nil {
fmt.Println(err)
}
// GetAllResources still returns *AwsAccountResources, but this struct has been extended with several
// convenience methods for quickly determining if resources exist in a given region
accountResources, err := nuke_aws.GetAllResources(context.Background(), query, nukeConfig)
if err != nil {
fmt.Println(err)
}
// You can call GetRegion to examine a single region's resources
usWest1Resources := accountResources.GetRegion("us-west-1")
// Then interrogate them with the new methods:
// Count the number of any resource type within the region
countOfEc2InUsWest1 := usWest1Resources.CountOfResourceType("ec2")
fmt.Printf("countOfEc2InUsWest1: %d\n", countOfEc2InUsWest1)
// countOfEc2InUsWest1: 2
fmt.Printf("usWest1Resources.ResourceTypePresent(\"ec2\"):%b\n", usWest1Resources.ResourceTypePresent("ec2"))
// usWest1Resources.ResourceTypePresent("ec2"): true
// Get all the resource identifiers for a given resource type
// In this example, we're only looking for ec2 instances
resourceIds := usWest1Resources.IdentifiersForResourceType("ec2")
fmt.Printf("resourceIds: %s", resourceIds)
// resourceIds: [i-0c5d16c3ef28dda24 i-09d9739e1f4d27814]
}
Config file
You can also specify which resources to terminate with more granularity via using config files. The config file is a YAML file that specifies which resources to terminate. The top level keys of the config file are the resource types, and the values are the rules for which resources to terminate. See examples folder for more reference.
Filtering Features
For each resource type, you can specify either include
or exclude
rules. Each rule can be one of the following
filters mentioned below. Here is an example:
s3:
include:
...
exclude:
...
Names Regex Filter
Now given the following config, the s3 buckets that will be nuked are further filtered to only include ones that match
any of the provided regular expressions. So a bucket named alb-app-access-logs
would be deleted, but a bucket
named my-s3-bucket
would not.
s3:
include:
names_regex:
- ^alb-.*-access-logs$
- .*-prod-alb-.*
Similarly, you can adjust the config to delete only IAM users of a particular name by using the IAMUsers
key. For
example, in the following config, only IAM users that have the prefix my-test-user-
in their username will be deleted.
IAMUsers:
include:
names_regex:
- ^my-test-user-.*
Now consider the following contrived example:
s3:
include:
names_regex:
- ^alb-.*-access-logs$
- .*-prod-alb-.*
exclude:
names_regex:
- public
- prod
The intention is to delete all the s3 buckets that match the include rules but not the exclude rules. Filtering is commutative, meaning that you should get the same result whether you apply the include filters before or after the exclude filters.
The result of these filters applied in either order will be a set of s3 buckets that match ^alb-.*-access-logs$
as
long as they do not also contain public
or prod
. The rule to include s3 buckets matching .*-prod-alb-.*
is negated
by the rule to exclude those matching prod
.
Time Filter
You can also filter resources by time. The following config will delete all s3 buckets that were created after
2020-01-01T00:00:00Z
.
s3:
include:
time_after: '2020-01-01T00:00:00Z'
Similarly, you can delete all s3 buckets that were created before 2020-01-01T00:00:00Z
by using the time_before
s3:
include:
time_before: '2020-01-01T00:00:00Z'
Tag Filter
You can also exclude resources by tags. The following config will exclude all s3 buckets that have a tag with key foo
and value true
(case-insensitive).
s3:
exclude:
tag: 'foo'
Timeout
You have the flexibility to set individual timeout options for specific resources. The execution will pause until the designated timeout is reached for each resource.
s3:
timeout: 10m
........
s3:
timeout: 5s
By default, it will use the exclusion default tag: cloud-nuke-excluded
to exclude resources.
Note: it doesn't support including resources by tags.

Unsupported Resources
Please note that the eligibility check for nukability relies on the DryRun
feature provided by AWS. Regrettably, this feature is not available for all delete APIs of resource types. Hence, the 'eligibility check for nukability' option may not be accessible for all resource types
How to Use
Once you created your config file, you can run a command like this to nuke resources with your config file:
cloud-nuke aws --resource-type s3 --config path/to/file.yaml
CLI options override config file options
The options provided in the command line take precedence over those provided in any config file that gets passed in. For example, say you provide
--resource-type s3
in the command line, along with a config file that specifiesec2:
at the top level but doesn't specifys3:
. The command line argument filters the resource types to include only s3, so the rules in the config file forec2:
are ignored, and ec2 resources are not nuked. All s3 resources would be nuked.In the same vein, say you do not provide a
--resource-type
option in the command line, but you do pass in a config file that only lists rules fors3:
, such ascloud-nuke aws --config path/to/config.yaml
. In this case all resources would be nuked, but amongs3
buckets, only those matching your config file rules would be nuked.Be careful when nuking and append the
--dry-run
option if you're unsure. Even without--dry-run
,cloud-nuke
will list resources that would undergo nuking and wait for your confirmation before carrying it out.
Log level
By default, cloud-nuke sends most output to the Debug
level logger, to enhance legibility, since the results of every
deletion attempt will be displayed in the report that cloud-nuke prints after each run.
However, sometimes it's helpful to see all output, such as when you're debugging something.
You can set the log level by specifying the --log-level
flag as per logrus log
levels:
cloud-nuke aws --log-level debug
OR
LOG_LEVEL=debug cloud-nuke aws
Default value is - info
. Acceptable values are debug, info, warn, error, panic, fatal, trace
as
per logrus log level parser.
Nuking only default security group rules
When deleting defaults with cloud-nuke defaults-aws
, use the --sg-only
flag to delete only the default
security group rules and not the default VPCs.
cloud-nuke defaults-aws --sg-only
Note for nuking VPCs
When nuking VPCs cloud-nuke will attempt to remove dependency resources underneath the VPC
Supported VPC sub-resources
- Internet Gateways
- Egress Only Internet Gateways
- Elastic Network Interfaces
- VPC Endpoints
- Subnets
- Route Tables
- Network ACLs
- Security Groups
- DHCP Option Sets (Will be dissociated from VPC, not deleted. Must be cleaned up separately)
- Elastic IPs (Supported as a separate resource that gets cleaned up first. If you are filtering what gets nuked, Elastic IPs may prevent VPCs from destroying.)
All other resources that get created within VPCs must be cleaned up prior to running cloud-nuke on VPC resources.
VPC resources may not be entirely cleaned up on the first run. We believe this is caused by an eventual consistency error in AWS.
If you see errors like
InvalidParameterValue: Network interface is currently in use.
We recommend waiting 30 minutes and trying again.
Happy Nuking!!!
Credentials
AWS
In order for the cloud-nuke
CLI tool to access your AWS, you will need to provide your AWS credentials. You can use
one of
the standard AWS CLI credential mechanisms.
Running Tests
go test -v ./...
Contributing
cloud-nuke is an open source project, and contributions from the community are very welcome! Please check out the Contribution Guidelines and Developing cloud-nuke for instructions.
Developing cloud-nuke
Running Locally
To run cloud-nuke locally, use the go run
command:
go run main.go
Running tests
Note: Many of the tests in the aws
folder run against a real AWS account and will create and destroy actual
resources. DO NOT
hit CTRL+C
while the tests are running, as this will prevent them from cleaning up properly. We are not responsible
for any
charges you may incur.
Before running the tests, you must configure your AWS credentials.
To run all the tests:
go test -v ./...
To run only the tests in a specific package, such as the package aws
:
cd aws
go test -v
And to run a specific test, such as TestListAMIs
in package aws
:
cd aws
go test -v -run TestListAMIs
And to run a specific test, such as TestLambdaFunction_GetAll
in package aws/resources
:
cd aws/resources
go test -v -run TestLambdaFunction_GetAll
Use env-vars to opt-in to special tests, which are expensive to run:
# Run acmpca tests
TEST_ACMPCA_EXPENSIVE_ENABLE=1 go test -v ./...
Formatting
Every source file in this project should be formatted with go fmt

Releasing new versions
We try to follow the release process as deifned in our Coding Methodology.
Choosing a new release tag
If the new release contains any new resources that cloud-nuke
will support, mark it as a minor version bump (X in
v0.X.Y)
to indicate backward incompatibilities.
This is because since version v0.2.0
cloud-nuke
has been configured to automatically include new resources (so you
have
to explicitly opt-out). This is inherently not backward compatible, because users with CI practices around cloud-nuke
would
be surprised by new resources that are suddenly being picked up for deletion! This surprise is more alarming for
resources
that are actively in use for any account, such as IAM Users.
Therefore please mark your release as backward incompatible and bump the minor version (X
in v0.X.Y
) when it
includes
support for nuking new resources, so that we provide better signals for users when we introduce a new resource.
To release a new version
Go to the Releases Page and create a new release. The CircleCI job for this repo has been configured to:
- Automatically detect new tags.
- Build binaries for every OS using that tag as a version number.
- Upload the binaries to the release in GitHub.
See .circleci/config.yml
for details.
Nukable error statuses
You'll encounter any of the following statuses when attempting to nuke resources, and here's what each status means:
error:INSUFFICIENT_PERMISSION
: You don't have enough permission to nuke the resource.error:DIFFERENT_OWNER
: You are attempting to nuke a resource for which you are not the owner.
