2022-12-13Drop obsolete client-go auth plugins (#5806)Gravatar Stephen Kitt 1-3/+1
* Drop obsolete client-go auth plugins The OpenStack plugin is no longer available, even in version 0.24.4 of client-go; see https://github.com/kubernetes/client-go/blob/v0.24.4/plugin/pkg/client/auth/openstack/openstack_stub.go It is replaced by the client-keystone-auth credential plugin. The plugin has been entirely removed in client-go 0.26.0, which breaks the build when any other dependency pulls in client-go 0.26.0 or later. The GCP plugin is deprecated in K8s 1.22+ and unavailable in 1.26+ (although it is still stubbed in client-go 0.26.0). Is it replaced by the gke-gcloud-auth-plugin credential plugin.

2021-05-17reverse zone: fix Normalize (#4621)Gravatar Miek Gieben 1-13/+1
Make normalize return multiple "hosts" (= reverse zones) when a non-octet boundary cidr is given. Added pkg/cidr package that holds the cidr calculation routines; felt they didn't really fit dnsutil. This change means the IPNet return parameter isn't needed, the hosts are all correct. The tests that tests this is also removed: TestSplitHostPortReverse The fallout was that zoneAddr _also_ doesn't need the IPNet member, that in turn make it visible that zoneAddr in address.go duplicated a bunch of stuff from register.go; removed/refactored that too. Created a plugin.OriginsFromArgsOrServerBlock to help plugins do the right things, by consuming ZONE arguments; this now expands reverse zones correctly. This is mostly mechanical. Remove the reverse test in plugin/kubernetes which is a copy-paste from a core test (which has since been fixed). Remove MustNormalize as it has no plugin users. This change is not backwards compatible to plugins that have a ZONE argument that they parse in the setup util. All in-tree plugins have been updated. Signed-off-by: Miek Gieben <miek@miek.nl>

2019-09-20all: simply registering plugins (#3287)Gravatar Miek Gieben 1-6/+1
Abstract the caddy call and make it simpler. See #3261 for some part of the discussion. Go from: ~~~ go func init() { caddy.RegisterPlugin("any", caddy.Plugin{ ServerType: "dns", Action: setup, }) } ~~~ To: ~~~ go func init() { plugin.Register("any", setup) } ~~~ This requires some external documents in coredns.io to be updated as well; the old way still works, so it's backwards compatible.

2019-01-13Default to upstream to self (#2436)Gravatar Miek Gieben 1-6/+2
* Default to upstream to self This is a backwards incompatible change. This is a massive (cleanup) PR where we default to resolving external names by the coredns process itself, instead of directly forwarding them to some upstream. This ignores any arguments `upstream` may have had and makes it depend on proxy/forward configuration in the Corefile. This allows resolved upstream names to be cached and we have better healthchecking of the upstreams. It also means there is only one way to resolve names, by either using the proxy or forward plugin. The proxy/forward lookup.go functions have been removed. This also lessen the dependency on proxy, meaning deprecating proxy will become easier. Some tests have been removed as well, or moved to the top-level test directory as they now require a full coredns process instead of just the plugin. For the etcd plugin, the entire StubZone resolving is *dropped*! This was a hacky (but working) solution to say the least. If someone cares deeply it can be brought back (maybe)? The pkg/upstream is now very small and almost does nothing. Also the New() function was changed to return a pointer to upstream.Upstream. It also returns only one parameter, so any stragglers using it will encounter a compile error. All documentation has been adapted. This affected the following plugins: * etcd * file * auto * secondary * federation * template * route53 A followup PR will make any upstream directives with arguments an error, right now they are ignored.
