+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to making participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, gender identity and expression, level of experience,
+nationality, personal appearance, race, religion, or sexual identity and
+orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or
+  advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic
+  address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at security@shopify.com. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.

+# kubeaudit
+
+:cloud: :lock: :muscle:
+
+## What's all this then?
+
+`kubeaudit` is a command line tool written in golang to help you audit your Kubernetes cluster. This tool can audit for the following scenarios:
+- [Audit security context](#sc)
+- [Audit container image](#image)
+- [Audit network policies](#netpol)
+- [Audit RBAC policies](#rbac)
+
+## Installation
+
+Add kubeaudit and its dependencies by running the following command:
+
+```sh
+go get -v github.com/Shopify/kubeaudit
+make
+```
+
+Upon completion you should find kubeaudit in `$GOPATH/bin/kubeaudit`
+
+## Running tests
+```sh
+make test
+```
+
+## Usage
+
+### General instructions
+
+kubeaudit is driven by [cobra](https://github.com/spf13/cobra) on the command line
+```raw
+kubeaudit is a program that will help you audit
+your Kubernetes clusters. Specify -l to run kubeaudit using ~/.kube/config
+otherwise it will attempt to create an in-cluster client.
+
+#patcheswelcome
+
+Usage:
+  kubeaudit [command]
+
+Available Commands:
+  help        Help about any command
+  image       Audit container images
+  np          Audit namespace network policies
+  rbac        Audit RBAC things
+  sc          Audit container security contexts
+
+Flags:
+  -a, --allPods             Audit againsts pods in all the phases (default Running Phase)
+  -h, --help                help for kubeaudit
+  -j, --json                Enable json logging
+  -c, --kubeconfig string   config file (default is $HOME/.kube/config
+  -l, --local               Local mode, uses ~/.kube/config as configuration
+  -v, --verbose             Enable debug (verbose) logging
+
+Use "kubeaudit [command] --help" for more information about a command.
+```
+
+<a name="sc" />
+
+### Audit security contexts
+
+It can audit against three different scenarios.
+
+1. General security context which make sure that every Kubernetes pod has a proper security context i.e. privileged linux capabilities are dropped or not:
+
+```sh
+% kubeaudit -l sc
+ERRO[0004] test/testDeployment                                                       type=deployment
+WARN[0004] Capabilities added to test/testStateSet  caps="[IPC_LOCK SYS_RESOURCE]"   type=statefulSet
+WARN[0004] No capabilities were dropped! test/testDaemonSet                          type=daemonSet
+```
+
+2. Every Kubernetes pod should have a read-only root file system:
+
+```sh
+% kubeaudit -l sc rootfs
+ERRO[0005] testbuilder/testpod-312-3213                  type=pod
+```
+
+3. Every container is running as non-root user:
+
+```sh
+% kubeaudit -l sc nonroot
+ERRO[0004] test/testPod                                  type=pod
+```
+
+<a name="image" />
+
+### Audit container image tags
+
+It checks that every Kubernetes resource is running the specified tag of a given image:
+
+```sh
+% kubeaudit -l image -i gcr.io/google_containers/echoserver:1.7
+ERRO[0005] test/testReplicationController               type=replicationController
+```
+
+<a name="netpol" />
+
+### Audit network policies
+
+It checks that every namespace should have a default deny network policiy installed. See [Kubernetes Network Policies](https://Kubernetes.io/docs/concepts/services-networking/network-policies/) for more information:
+
+```sh
+# don't specify -l or -c to run inside the clsuter
+% kubeaudit np
+WARN[0000] Default allow mode on test/testing           type=netpol
+```
+
+<a name="rbac" />
+
+### Audit RBAC policies
+
+It audits against the following scenarios:
+
+- Check for automountServiceAccountToken is nil with no serviceAccountName
+- Check for usage of deprecated serviceAccount
+
+```sh
+% kubeaudit -l rbac sat
+ERRO[0000] automountServiceAccountToken nil (mounted by default) with no serviceAccountName name=alpine namespace=test type=deployment
+WARN[0000] deprecated serviceAccount detected (sub for serviceAccountName)  name=nginx namespace=staging serviceAccount=nginx serviceAccountName=nginx type=deployment
+```
