webhooks](https://kubernetes.io/docs/reference/access-authn-authz/extensible-admission-controllers/). +It can be used as one of the validating webhooks to be used and scan new configurations. + +In this guide, we'll demonstrate how Terrascan can be configured to: +* Scan configuration changes policies when an object is being created or updated +* Allow / reject the request in case a violation is detected + + +## Installation Guide + +### Create an instance +Your Terrascan instance has the following requirements for being able to scan K8s configurations. + +1. Be accessible via HTTPS. Make sure your cloud firewall is configured to allow this. +2. Have a valid SSL certificate for the served domain name. To do that, choose one of our suggested methods: + - Use a subdomain of your choosing (e.g dev-terrascan-k8s.accurics.com) and create a valid certificate for this subdomain through your SSL certificate provider. [Let's Encrypt](https://letsencrypt.org/) is a free, simple to use certificate authority you can use. + - Use a reverse-proxy to serve SSL requests; for example, use Cloudflare Flexible to get a certificate by a trusted-CA to your [self-signed certificate](https://www.digitalocean.com/community/tutorials/openssl-essentials-working-with-ssl-certificates-private-keys-and-csrs). + - Generate a self-signed certificate and have your K8s cluster trust it. To add a trusted CA to ca-pemstore, as demonstrated in [paraspatidar's blog post](https://medium.com/@paraspatidar/add-ssl-tls-certificate-or-pem-file-to-kubernetes-pod-s-trusted-root-ca-store-7bed5cd683d). +3. Use the Terrascan docker as demonstrated in this document, or run it from the sources. + +### Run Terrascan webhook service +Run Terrascan docker image in your server using the following command: + ```bash + sudo docker run -p 443:9443 -v :/data -u root -e K8S_WEBHOOK_API_KEY= accurics/terrascan server --cert-path /data/cert.pem --key-path /data/key.pem -c /data/config.toml + ``` +`` is a key used for authentication between your K8s environment and the Terrascan server. Generate your preferred key and use it here. + +`` is a directory path in your server where both the certificate and the private key .pem files are stored. +In addition, this directory is used to save the webhook logs. (An SQLite file) + +You can specify a config file that specifies which policies to use in the scan and which violations should lead to rejection. + +A config file example: ```config.toml``` + ```bash +[severity] +level = "medium" +[rules] + skip-rules = [ + "accurics.kubernetes.IAM.107" + ] + +[k8s-deny-rules] + denied-categories = [ + "Network Ports Security" + ] + denied-severity = "high" + ``` + +You can specify the following configurations: +* **scan-rules** - one or more rules to scan +* **skip-rules** - one or more rules to skip while scanning +* **severity** - the minimal level of severity of the policies to be scanned +* **category** - the list of type of categories of the policies to be scanned + + +* **k8s-deny-rules** - specify the rules that should cause a rejection of the admission request + * **denied-categories** - one or more policy categories that are not allowed in the detected violations + * **denied-severity** - the minimal level of severity that should cause a rejection + +### Configure K8s to send webhooks +Configure a new ```ValidatingWebhookConfiguration``` in your Kubernetes environment and specify your Terrascan server endpoint. + +Example: + ```bash + cat </v1/k8s/webhooks//scan + sideEffects: None + admissionReviewVersions: ["v1"] + EOF + ``` + +* You can modify the `rules` that trigger the webhook according to your preferences. +* Update the ```clientConfig``` URL with your terrascan server address and the API key you generated before. + + +### Test your settings +Try to run a new pod / service.
