https://docs.traefik.io/configuration/backends/kubernetes/#general-annotations Says that the traefik.ingress.kubernetes.io/rule-type annotation overrides the the default frontend rule type.
Is there any way to set the default frontend rule type to PathPrefixStrip so I will not have to override it in every single Ingress definition?
As far as I know, you can use Traefik Static configuration file and explicitly propagate global configuration for entrypoints, frontends and backends objects.
Static config applies Traefik settings at the traefik-ingress-controller initialization phase, thus all dynamically created sources, like K8s Ingress resources may override some key-value parameters as per precedence order behavior.
Therefore, you might consider including Matcher route rules via PathPrefixStrip parameter for the target Frontends within a global configuration file, i.e:
[frontends]
[frontends.frontend1]
backend = "backend1"
[frontends.frontend1.routes.test_1]
rule = "PathPrefixStrip:/somepath"More details about Traefik TOML file template and design you can find here.
No, in traefik 1.7 default fronted rule is hardcoded and not documented. https://github.com/containous/traefik/blob/v1.7/provider/kubernetes/kubernetes.go#L48
defaultFrontendRule = "PathPrefix:/"
//...
if len(frontend.Routes) == 0 {
frontend.Routes["/"] = types.Route{
Rule: defaultFrontendRule,
}
}
//...
templateObjects.Frontends[defaultFrontendName].Routes["/"] = types.Route{
Rule: defaultFrontendRule,
}
