Changing the Expiration Days for Newly Signed Certificates

By default, a newly signed certificate is set to expire 365 days (1 year) after its creation time and date. You can use the CATTLE_NEW_SIGNED_CERT_EXPIRATION_DAYS environment variable to change this value.

Please note: the value for the aforementioned variable must be a string representing an unsigned integer corresponding to the number of days until expiration (i.e. X509 "NotAfter" value).

Functions

func HTTPRedirect

func HTTPRedirect(next http.Handler) http.Handler

Approach taken from letsencrypt, except manglePort is specific to us

func NewListener

func NewListener(l net.Listener, storage TLSStorage, caCert *x509.Certificate, caKey crypto.Signer, config Config) (net.Listener, http.Handler, error)

Deprecated: Use NewListenerWithChain instead as it supports intermediate CAs

func NewListenerWithChain

func NewListenerWithChain(l net.Listener, storage TLSStorage, caCert []*x509.Certificate, caKey crypto.Signer, config Config) (net.Listener, http.Handler, error)

func NewTCPListener

func NewTCPListener(ip string, port int) (net.Listener, error)

func OnlyAllow

func OnlyAllow(str string) func(...string) []string
