Functions

func FileExists

func FileExists(filename string) bool

FileExists checks if a file exists and is not a directory before we try using it to prevent further errors.

func FindKubeConfigPath

func FindKubeConfigPath(path ...string) (string, error)

FindKubeConfigPath checks will return a path for the kubernetes config file

func GetClusterRoleBindingSpec

func GetClusterRoleBindingSpec(cs kubernetes.Clientset) (clusterRoleBinding []string, err error)

GetClusterRoleBindingSpec provide a list an of JSON Cluster Role Binding specs from the clientset

func GetDeploymentSpec

func GetDeploymentSpec(cs kubernetes.Clientset, namespace string) (deploy []string, err error)

GetDeploymentSpec provide a list an of JSON Deployment specs from the clientset

func GetFormattedJSON

func GetFormattedJSON(source string) (result string)

GetFormattedJSON takes a source string and outputs a formatted JSON string using 2 space characters as the indent

func GetIngressSpec

func GetIngressSpec(cs kubernetes.Clientset, namespace string) (ingress []string, err error)

GetIngressSpec provide a list an of JSON Ingress specs from the clientset /!\ The only rule we currently have doesn't seem to be triggerable /!\ K8S-IN-0001: https://github.com/reliablyhq/opa-policies/blob/main/kubernetes/ingress.rego /!\ It looks for indentical Ingress hosts in different namespaces, and we are currently working /!\ in only one namespace, passed as a parameter. /!\ Probably a TODO here.

func GetKubernetesClientSet

func GetKubernetesClientSet(kubeconfigPath, context string) (*kubernetes.Clientset, error)

GetKubernetesClientSet uses the default kubectl config file to create a Clientset for the default config

func GetNodeSpec

func GetNodeSpec(cs kubernetes.Clientset) (nodes []string, err error)

GetNodeSpec returns the list of JSON Nodes specs from the clientset

func GetPodSecurityPolicySpec

func GetPodSecurityPolicySpec(cs kubernetes.Clientset) (podSecPol []string, err error)

GetPodSecurityPolicySpec provide a list an of JSON Pod Security Policy specs from the clientset

func GetPodSpec

func GetPodSpec(cs kubernetes.Clientset, namespace string) (po []string, err error)

GetPodSpec provide a list an of JSON Pod specs from the clientset

func GetResourceList

func GetResourceList(cs kubernetes.Clientset, namespace string) []string
