Functions

func CIDRsDontOverlap

func CIDRsDontOverlap(acidr, bcidr string) error

CIDRsDontOverlap ensures two given CIDRs don't overlap with one another. CIDR starting IPs are canonicalized before being compared.

func ClusterName

func ClusterName(v string) error

ClusterName checks if the given string is a valid name for a cluster and returns an error if not.

func DomainName

func DomainName(v string) error

DomainName checks if the given string is a valid domain name and returns an error if not.

func Email

func Email(v string) error

Email checks if the given string is a valid email address and returns an error if not.

func IPv4

func IPv4(v string) error

IPv4 checks if the given string is a valid IP v4 address and returns an error if not. Based on net.ParseIP.

func JSON

func JSON(data []byte) error

JSON validates that the given data is valid JSON.

func S3Bucket

func S3Bucket(name string) error

S3Bucket does some basic validation to ensure that the S3 bucket matches the S3 bucket naming rules. Not all rules are checked because Tectonic controls the generation of S3 bucket names, creating buckets of the form: <cluster-name>.<domain-name> If domain-name contains a trailing dot, it's removed from the bucket name.

func SubnetCIDR

func SubnetCIDR(v string) error

SubnetCIDR checks if the given string is a valid CIDR for a master nodes or worker nodes subnet and returns an error if not.
