What is doggo?

doggo is a modern command-line DNS client (like dig) written in Golang. It outputs information in a neat concise manner and supports protocols like DoH, DoT, DoQ, and DNSCrypt as well. To learn more about the doggo scanner itself visit doggo GitHub.

Deployment

The doggo chart can be deployed via helm:

# Install HelmChart (use -n to configure another namespace)
helm upgrade --install doggo secureCodeBox/doggo

Scanner Configuration

The following security scan configuration example are based on the doggo User Guide, please take a look at the original documentation for more configuration examples.

  • Do a simple DNS Lookup: doggo example.com
  • Query MX records for github.com using 9.9.9.9 resolver: doggo MX github.com @9.9.9.9

Requirements

Kubernetes: >=v1.11.0-0

Values

KeyTypeDefaultDescription
cascadingRules.enabledboolfalseEnables or disables the installation of the default cascading rules for this scanner
imagePullSecretslist[]Define imagePullSecrets when a private registry is used (see: https://kubernetes.io/docs/tasks/configure-pod-container/pull-image-private-registry/)
parser.affinityobject{}Optional affinity settings that control how the parser job is scheduled (see: https://kubernetes.io/docs/tasks/configure-pod-container/assign-pods-nodes-using-node-affinity/)
parser.envlist[]Optional environment variables mapped into each parseJob (see: https://kubernetes.io/docs/tasks/inject-data-application/define-environment-variable-container/)
parser.image.pullPolicystring"IfNotPresent"Image pull policy. One of Always, Never, IfNotPresent. Defaults to Always if :latest tag is specified, or IfNotPresent otherwise. More info: https://kubernetes.io/docs/concepts/containers/images#updating-images
parser.image.repositorystring"docker.io/securecodebox/parser-doggo"Parser image repository
parser.image.tagstringdefaults to the charts versionParser image tag
parser.resourcesobject{ requests: { cpu: "200m", memory: "100Mi" }, limits: { cpu: "400m", memory: "200Mi" } }Optional resources lets you control resource limits and requests for the parser container. See https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/
parser.scopeLimiterAliasesobject{}Optional finding aliases to be used in the scopeLimiter.

parser.ttlSecondsAfterFinishedstringnilseconds after which the Kubernetes job for the parser will be deleted. Requires the Kubernetes TTLAfterFinished controller: https://kubernetes.io/docs/concepts/workloads/controllers/ttlafterfinished/
scanner.activeDeadlineSecondsstringnilThere are situations where you want to fail a scan Job after some amount of time. To do so, set activeDeadlineSeconds to define an active deadline (in seconds) when considering a scan Job as failed. (see: https://kubernetes.io/docs/concepts/workloads/controllers/job/#job-termination-and-cleanup)
scanner.affinityobject{}Optional affinity settings that control how the scanner job is scheduled (see: https://kubernetes.io/docs/tasks/configure-pod-container/assign-pods-nodes-using-node-affinity/)
scanner.backoffLimitint3There are situations where you want to fail a scan Job after some amount of retries due to a logical error in configuration etc. To do so, set backoffLimit to specify the number of retries before considering a scan Job as failed. (see: https://kubernetes.io/docs/concepts/workloads/controllers/job/#pod-backoff-failure-policy)
scanner.envlist[]Optional environment variables mapped into each scanJob (see: https://kubernetes.io/docs/tasks/inject-data-application/define-environment-variable-container/)
scanner.extraContainerslist[]Optional additional Containers started with each scanJob (see: https://kubernetes.io/docs/concepts/workloads/pods/init-containers/)
scanner.extraVolumeMountslist[]Optional VolumeMounts mapped into each scanJob (see: https://kubernetes.io/docs/concepts/storage/volumes/)
scanner.extraVolumeslist[]Optional Volumes mapped into each scanJob (see: https://kubernetes.io/docs/concepts/storage/volumes/)

scanner.resourcesobject{}CPU/memory resource requests/limits (see: https://kubernetes.io/docs/tasks/configure-pod-container/assign-memory-resource/, https://kubernetes.io/docs/tasks/configure-pod-container/assign-cpu-resource/)
scanner.securityContextobject{"allowPrivilegeEscalation":false,"capabilities":{"drop":["all"]},"privileged":false,"readOnlyRootFilesystem":true,"runAsNonRoot":true}Optional securityContext set on scanner container (see: https://kubernetes.io/docs/tasks/configure-pod-container/security-context/)
scanner.securityContext.allowPrivilegeEscalationboolfalseEnsure that users privileges cannot be escalated
scanner.securityContext.capabilities.drop[0]string"all"This drops all linux privileges from the container.
scanner.securityContext.privilegedboolfalseEnsures that the scanner container is not run in privileged mode
scanner.securityContext.readOnlyRootFilesystembooltruePrevents write access to the containers file system
scanner.securityContext.runAsNonRootbooltrueEnforces that the scanner image is run as a non root user
scanner.suspendboolfalseif set to true the scan job will be suspended after creation. You can then resume the job using kubectl resume <jobname> or using a job scheduler like kueue
scanner.tolerationslist[]Optional tolerations settings that control how the scanner job is scheduled (see: https://kubernetes.io/docs/concepts/scheduling-eviction/taint-and-toleration/)
