Kubeaudit can now be used as both a command line tool (CLI) and as a Go package!

kubeaudit ☁ 🔒 💪

kubeaudit is a command line tool and a Go package to audit Kubernetes clusters for various different security concerns, such as:

  • run as non-root
  • use a read-only root filesystem
  • drop scary capabilities, don't add new ones
  • don't run privileged
  • and more!

tldr. kubeaudit makes sure you deploy secure containers!

Package

To use kubeaudit as a Go package, see the package docs.

The rest of this README will focus on how to use kubeaudit as a command line tool.

Command Line Interface (CLI)

Installation

Brew
brew install kubeaudit
Download a binary

Kubeaudit has official releases that are blessed and stable: Official releases

DIY build

Master may have newer features than the stable releases. If you need a newer feature not yet included in a release you can do the following to get kubeaudit:

For go 1.12 and higher:

GO111MODULE=on go get -v github.com/Shopify/kubeaudit

For older versions of go:

git clone https://github.com/Shopify/kubeaudit.git
cd kubeaudit
make
make install

Start using kubeaudit with the Quick Start or view all the supported commands.

Kubectl Plugin

Prerequisite: kubectl v1.12.0 or later

With kubectl v1.12.0 introducing easy pluggability of external functions, kubeaudit can be invoked as kubectl audit by

  • running make plugin and having $GOPATH/bin available in your path.

or

  • renaming the binary to kubectl-audit and having it available in your path.
Docker

We also release a Docker image: shopify/kubeaudit. To run kubeaudit as a job in your cluster see Running kubeaudit in a cluster.

Quick Start

kubeaudit has three modes:

  1. Manifest mode
  2. Local mode
  3. Cluster mode
Manifest Mode

If a Kubernetes manifest file is provided using the -f/--manifest flag, kubeaudit will audit the manifest file.

Example command:

kubeaudit all -f "/path/to/manifest.yml"

Example output:

$ kubeaudit all -f "internal/test/fixtures/all_resources/deployment-apps-v1.yml"

---------------- Results for ---------------

  apiVersion: apps/v1
  kind: Deployment
  metadata:
    name: deployment
    namespace: deployment-apps-v1

--------------------------------------------

-- [error] AppArmorAnnotationMissing
   Message: AppArmor annotation missing. The annotation 'container.apparmor.security.beta.kubernetes.io/container' should be added.
   Metadata:
      Container: container
      MissingAnnotation: container.apparmor.security.beta.kubernetes.io/container

-- [error] AutomountServiceAccountTokenTrueAndDefaultSA
   Message: Default service account with token mounted. automountServiceAccountToken should be set to 'false' or a non-default service account should be used.

-- [error] CapabilityNotDropped
   Message: Capability not dropped. Ideally, the capability drop list should include the single capability 'ALL' which drops all capabilities.
   Metadata:
      Container: container
      Capability: AUDIT_WRITE
...
Autofix

Manifest mode also supports autofixing all security issues using the autofix command:

kubeaudit autofix -f "/path/to/manifest.yml"

To write the fixed manifest to a new file instead of modifying the source file, use the -o/--output flag.

kubeaudit autofix -f "/path/to/manifest.yml" -o "/path/to/fixed"
Cluster Mode

Kubeaudit can detect if it is running within a container in a cluster. If so, it will try to audit all Kubernetes resources in that cluster:

kubeaudit all
Local Mode

Kubeaudit will try to connect to a cluster using the local kubeconfig file ($HOME/.kube/config). A different kubeconfig location can be specified using the -c/--kubeconfig flag.

kubeaudit all -c "/path/to/config"

For more information on kubernetes config files, see https://kubernetes.io/docs/concepts/configuration/organize-cluster-access-kubeconfig/

Audit Results

Kubeaudit produces results with three levels of severity:

Error: A security issue or invalid kubernetes configuration Warning: A best practice recommendation Info: Informational, no action required. This includes results that are overridden

The minimum severity level can be set using the --minSeverity/-m flag.

By default kubeaudit will output results in a human-readable way. If the output is intended to be further processed, it can be set to output JSON using the --format json flag. To output results as logs (the previous default) use --format logrus.

If there are results of severity level error, kubeaudit will exit with exit code 2. This can be changed using the --exitcode/-e flag.

For all the ways kubeaudit can be customized, see Global Flags.

-m --minseverity Set the lowest severity level to report (one of "error", "warning", "info") (default "info")
-e --exitcode Exit code to use if there are results with severity of "error". Conventionally, 0 is used for success and all non-zero codes for an error. (default 2)

Configuration File

Kubeaudit can be used with a configuration file instead of flags. See the all command.

Override Errors

Security issues can be ignored for specific containers or pods by adding override labels. This means the auditor will produce info results instead of error results and the audit result name will have Allowed appended to it. The labels are documented in each auditor's documentation, but the general format for auditors that support overrides is as follows:

An override label consists of a key and a value.

The key is a combination of the override type (container or pod) and an override identifier which is unique to each auditor (see the docs for the specific auditor). The key can take one of two forms depending on the override type:

  1. Container overrides, which override the auditor for that specific container, are formatted as follows:
container.audit.kubernetes.io/[container name].[override identifier]
  1. Pod overrides, which override the auditor for all containers within the pod, are formatted as follows:
audit.kubernetes.io/pod.[override identifier]

If the value is set to a non-empty string, it will be displayed in the info result as the OverrideReason:

$ kubeaudit asat -f "auditors/asat/fixtures/service-account-token-true-allowed.yml"

---------------- Results for ---------------

  apiVersion: v1
  kind: ReplicationController
  metadata:
    name: replicationcontroller
    namespace: service-account-token-true-allowed

--------------------------------------------

-- [info] AutomountServiceAccountTokenTrueAndDefaultSAAllowed
   Message: Audit result overridden: Default service account with token mounted. automountServiceAccountToken should be set to 'false' or a non-default service account should be used.
   Metadata:
      OverrideReason: SomeReason

As per Kubernetes spec, value must be 63 characters or less and must be empty or begin and end with an alphanumeric character ([a-z0-9A-Z]) with dashes (-), underscores (_), dots (.), and alphanumerics between.

Multiple override labels (for multiple auditors) can be added to the same resource.

See the specific auditor docs for the auditor you wish to override for examples.

To learn more about labels, see https://kubernetes.io/docs/concepts/overview/working-with-objects/labels/

Documentation

Overview

Package kubeaudit provides methods to find and fix security issues in Kubernetes resources.

Modes

Kubeaudit supports three different modes. The mode used depends on the audit method used.

1. Manifest mode: Audit a manifest file

2. Local mode: Audit resources in a local kubeconfig file

3. Cluster mode: Audit resources in a running cluster (kubeaudit must be invoked from a container within the cluster)

In manifest mode, kubeaudit can automatically fix security issues.

Follow the instructions below to use kubeaudit:

First initialize the security auditors

The auditors determine which security issues kubeaudit will look for. Each auditor is responsible for a different security issue. For an explanation of what each auditor checks for, see https://github.com/Shopify/kubeaudit#auditors.

To initialize all available auditors:

import "github.com/Shopify/kubeaudit/auditors/all"

auditors, err := all.Auditors(config.KubeauditConfig{})

Or, to initialize specific auditors, import each one:

import (
  "github.com/Shopify/kubeaudit/auditors/apparmor"
  "github.com/Shopify/kubeaudit/auditors/image"
)

auditors := []kubeaudit.Auditable{
  apparmor.New(),
  image.New(image.Config{Image: "myimage:mytag"}),
}

Initialize Kubeaudit

Create a new instance of kubeaudit:

kubeAuditor, err := kubeaudit.New(auditors)

Run the audit

To run the audit in manifest mode:

import "os"

manifest, err := os.Open("/path/to/manifest.yaml")
if err != nil {
  ...
}

report, err := kubeAuditor.AuditManifest(manifest)

Or, to run the audit in local mode:

report, err := kubeAuditor.AuditLocal("/path/to/kubeconfig.yml")

Or, to run the audit in cluster mode (pass it a namespace name as a string to only audit resources in that namespace, or an empty string to audit resources in all namespaces):

report, err := auditor.AuditCluster("")

Get the results

To print the results in a human readable way:

report.PrintResults(os.Stdout, kubeaudit.Info, nil)

Or, to get the result objects:

results := report.Results()

Autofix

Note that autofixing is only supported in manifest mode.

To print the plan (what will be fixed):

report.PrintPlan(os.Stdout)

To automatically fix the security issues and print the fixed manifest:

err = report.Fix(os.Stdout)

Override Errors

Overrides can be used to ignore specific auditors for specific containers or pods. See the documentation for the specific auditor you wish to override at https://github.com/Shopify/kubeaudit#auditors.

Custom Auditors

Kubeaudit supports custom auditors. See the Custom Auditor example.

Example

Example shows how to audit and fix a Kubernetes manifest file

package main

import (
	"fmt"
	"os"
	"strings"

	"github.com/Shopify/kubeaudit"
	"github.com/Shopify/kubeaudit/auditors/all"

)

func main() {
	// A sample Kubernetes manifest file
	manifest := `
apiVersion: apps/v1
kind: Deployment
metadata:
  name: myAuditor 
  spec:
    template:
      spec:
        containers:
        - name: myContainer
`

	// Initialize all the security auditors using default configuration
	allAuditors, err := all.Auditors(config.KubeauditConfig{})
	if err != nil {
		log.Fatal(err)
	}

	// Initialize kubeaudit
	auditor, err := kubeaudit.New(allAuditors)
	if err != nil {
		log.Fatal(err)
	}

	// Run the audit in manifest mode
	report, err := auditor.AuditManifest(strings.NewReader(manifest))
	if err != nil {
		log.Fatal(err)
	}

	// Print the audit results to screen
	report.PrintResults()

	// Print the plan to screen. These are the steps that will be taken by calling "report.Fix()".
	fmt.Println("\nPlan:")
	report.PrintPlan(os.Stdout)

	// Print the fixed manifest to screen. Note that this leaves the original manifest unmodified.
	fmt.Println("\nFixed manifest:")
	err = report.Fix(os.Stdout)
	if err != nil {
		log.Fatal(err)
	}
}
Output:

Example (AuditCluster)

ExampleAuditCluster shows how to run kubeaudit in cluster mode (only works if kubeaudit is being run from a container insdie of a cluster)

package main

	"github.com/Shopify/kubeaudit"
	"github.com/Shopify/kubeaudit/auditors/all"
	"github.com/Shopify/kubeaudit/config"
	"github.com/Shopify/kubeaudit/internal/k8s"

	log "github.com/sirupsen/logrus"
)

func main() {
	// Initialize all the security auditors using default configuration
	allAuditors, err := all.Auditors(config.KubeauditConfig{})
	if err != nil {
		log.Fatal(err)
	}

	// Initialize kubeaudit
	auditor, err := kubeaudit.New(allAuditors)
	if err != nil {
		log.Fatal(err)
	}

	// Run the audit in cluster mode. Note this will fail if kubeaudit is not running within a cluster.
	report, err := auditor.AuditCluster(k8s.ClientOptions{})
	if err != nil {
		log.Fatal(err)
	}

	// Print the audit results to screen
	report.PrintResults()
}
Output:

Example (AuditLocal)

	"github.com/Shopify/kubeaudit/internal/k8s"

	log "github.com/sirupsen/logrus"
)

func main() {
	// Initialize all the security auditors using default configuration
	allAuditors, err := all.Auditors(config.KubeauditConfig{})
	if err != nil {
		log.WithError(err).Fatal("Error initializing all auditors")
	}

	// Initialize kubeaudit
	auditor, err := kubeaudit.New(allAuditors)
	if err != nil {
		log.Fatal(err)
	}

	// Run the audit in local mode
	report, err := auditor.AuditLocal("", k8s.ClientOptions{})
	if err != nil {
		log.Fatal(err)
	}

	// Print the audit results to screen

}
Output:

Example (AuditorSubset)

ExampleAuditorSubset shows how to run kubeaudit with a subset of auditors

// Initialize the auditors you want to use

})
if err != nil {
	log.Fatal(err)
}

// Run the audit in the mode of your choosing. Here we use manifest mode.
report, err := auditor.AuditManifest(strings.NewReader(manifest))
if err != nil {
	log.Fatal(err)
}

// Print the audit results to screen
report.PrintResults()
Output:

Example (Config)

ExampleConfig shows how to use a kubeaudit with a config file. A kubeaudit config can be used to specify which security auditors to run, and to specify configuration for those auditors.

configFile := "config/config.yaml"

// Open the configuration file
reader, err := os.Open(configFile)
if err != nil {
	log.WithError(err).Fatal("Unable to open config file ", configFile)
}

// Load the config
conf, err := config.New(reader)
if err != nil {
