To make an impersonation request, first make a TokenCredentialRequest
to get a certificate. That cert will either be issued by the Kube
API server's CA or by a new CA specific to the impersonator. Either
way, you can then make a request to the impersonator and present
that client cert for auth and the impersonator will accept it and
make the impesonation call on your behalf.
The impersonator http handler now borrows some Kube library code
to handle request processing. This will allow us to more closely
mimic the behavior of a real API server, e.g. the client cert
auth will work exactly like the real API server.

This is more than an automatic merge. It also includes a rewrite of the CredentialIssuer API impersonation proxy fields using the new structure, and updates to the CLI to account for that new API.

This change adds a new virtual aggregated API that can be used by
any user to echo back who they are currently authenticated as. This
has general utility to end users and can be used in tests to
validate if authentication was successful.

- Watch a configmap to read the configuration of the impersonation
proxy and reconcile it.
- Implements "auto" mode by querying the API for control plane nodes.
- WIP: does not create a load balancer or proper TLS certificates yet.
Those will come in future commits.

As of upgrading to Kubernetes 1.20, our aggregated API server nows runs some
controllers for the two flowcontrol.apiserver.k8s.io resources in the title of
this commit, so it needs RBAC to read them.
This should get rid of the following error messages in our Concierge logs:
Failed to watch *v1beta1.FlowSchema: failed to list *v1beta1.FlowSchema: flowschemas.flowcontrol.apiserver.k8s.io is forbidden: User "system:serviceaccount:concierge:concierge" cannot list resource "flowschemas" in API group "flowcontrol.apiserver.k8s.io" at the cluster scope
Failed to watch *v1beta1.PriorityLevelConfiguration: failed to list *v1beta1.PriorityLevelConfiguration: prioritylevelconfigurations.flowcontrol.apiserver.k8s.io is forbidden: User "system:serviceaccount:concierge:concierge" cannot list resource "prioritylevelconfigurations" in API group "flowcontrol.apiserver.k8s.io" at the cluster scope

Previously, when triggering a Tilt reload via a *.go file change, a reload would
take ~13 seconds and we would see this error message in the Tilt logs for each
component.
Live Update failed with unexpected error:
command terminated with exit code 2
Falling back to a full image build + deploy
Now, Tilt should reload images a lot faster (~3 seconds) since we are running
the images as root.
Note! Reloading the Concierge component still takes ~13 seconds because there
are 2 containers running in the Concierge namespace that use the Concierge
image: the main Concierge app and the kube cert agent pod. Tilt can't live
reload both of these at once, so the reload takes longer and we see this error
message.
Will not perform Live Update because:
Error retrieving container info: can only get container info for a single pod; image target image:image/concierge has 2 pods
Falling back to a full image build + deploy

We believe this API is more forwards compatible with future secrets management
use cases. The implementation is a cry for help, but I was trying to follow the
previously established pattern of encapsulating the secret generation
functionality to a single group of packages.
This commit makes a breaking change to the current OIDCProvider API, but that
OIDCProvider API was added after the latest release, so it is technically still
in development until we release, and therefore we can continue to thrash on it.
I also took this opportunity to make some things private that didn't need to be
public.

This also sets the CSRF cookie Secret's OwnerReference to the Pod's grandparent
Deployment so that when the Deployment is cleaned up, then the Secret is as
well.
Obviously this controller implementation has a lot of issues, but it will at
least get us started.

We want to have our APIs respond to `kubectl get pinniped`, and we shouldn't use `all` because we don't think most average users should have permission to see our API types, which means if we put our types there, they would get an error from `kubectl get all`.
I also added some tests to assert these properties on all `*.pinniped.dev` API resources.

This is needed on clusters with PodSecurityPolicy enabled by default, but should be harmless in other cases.
This is generally needed because a restrictive PodSecurityPolicy will usually otherwise prevent the `hostPath` volume mount needed by the dynamically-created cert agent pod.

This is the beginning of a change to add cpu/memory limits to our pods.
We are doing this because some consumers require this, and it is generally
a good practice.
The limits == requests for "Guaranteed" QoS.

I tried to follow a principle of encapsulation here - we can still default to

This is the first of a few related changes that re-organize our API after the big recent changes that introduced the supervisor component.
Signed-off-by: Matt Moyer <moyerm@vmware.com>
- TLS certificates can be configured on the OIDCProviderConfig using
the `secretName` field.
- When listening for incoming TLS connections, choose the TLS cert
based on the SNI hostname of the incoming request.
- Because SNI hostname information on incoming requests does not include
the port number of the request, we add a validation that
OIDCProviderConfigs where the issuer hostnames (not including port
number) are the same must use the same `secretName`.
- Note that this approach does not yet support requests made to an
IP address instead of a hostname. Also note that `localhost` is
considered a hostname by SNI.
- Add port 443 as a container port to the pod spec.
- A new controller watches for TLS secrets and caches them in memory.
That same in-memory cache is used while servicing incoming connections
on the TLS port.
- Make it easy to configure both port 443 and/or port 80 for various
Service types using our ytt templates for the supervisor.
- When deploying to kind, add another nodeport and forward it to the
host on another port to expose our new HTTPS supervisor port to the
host.
- When two different Issuers have the same host (i.e. they differ
only by path) then they must have the same secretName. This is because
it wouldn't make sense for there to be two different TLS certificates
for one host. Find any that do not have the same secret name to
put an error status on them and to avoid serving OIDC endpoints for
them. The host comparison is case-insensitive.
- Issuer hostnames should be treated as case-insensitive, because
DNS hostnames are case-insensitive. So https://me.com and
https://mE.cOm are duplicate issuers. However, paths are
case-sensitive, so https://me.com/A and https://me.com/a are
different issuers. Fixed this in the issuer validations and in the
OIDC Manager's request router logic.
When using kind we forward the node's port to the host, so we only
really care about the `nodePort` value. For acceptance clusters,
we put an Ingress in front of a NodePort Service, so we only really
care about the `port` value.
Based on our experiences today with GKE, it will be easier for our users
to configure Ingress health checks if the healthz endpoint is available
on the same public port as the OIDC endpoints.
Also add an integration test for the healthz endpoint now that it is
public.
Also add the optional `containers[].ports.containerPort` to the
supervisor Deployment because the GKE docs say that GKE will look
at that field while inferring how to invoke the health endpoint. See
https://cloud.google.com/kubernetes-engine/docs/concepts/ingress#def_inf_hc
- New optional ytt value called `into_namespace` means install into that
preexisting namespace rather than creating a new namespace for each app
- Also ensure that every resource that is created statically by our yaml
at install-time by either app is labeled consistently
- Also support adding custom labels to all of those resources from a
new ytt value called `custom_labels`
Add install-pinniped-supervisor.yaml and rename install-pinniped.yaml
to install-pinniped-concierge.yaml in the release process and
installation/demo documentation.
- Tiltfile and prepare-for-integration-tests.sh both specify the
NodePort Service using `--data-value-yaml 'service_nodeport_port=31234'`
- Also rename the namespaces used by the Concierge and Supervisor apps
during integration tests running locally
- Also continue renaming things related to the concierge app
- Enhance the uninstall test to also test uninstalling the supervisor
and local-user-authenticator apps
