This change updates the pinniped CLI entrypoint to prevent browser
processes that we spawn from polluting our std out stream.
For example, chrome will print the following message to std out:
Opening in existing browser session.
Which leads to the following incomprehensible error message from
kubectl:
Unable to connect to the server: getting credentials:
decoding stdout: couldn't get version/kind; json parse error:
json: cannot unmarshal string into Go value of type struct
{ APIVersion string "json:\"apiVersion,omitempty\"";
Kind string "json:\"kind,omitempty\"" }
This would only occur on the initial login when we opened the
browser. Since credentials would be cached afterwards, kubectl
would work as expected for future invocations as no browser was
opened.
I could not think of a good way to actually test this change. There
is a clear gap in our integration tests - we never actually launch a
browser in the exact same way a user does - we instead open a chrome
driver at the login URL as a subprocess of the integration test
binary and not the pinniped CLI. Thus even if the chrome driver was
writing to std out, we would not notice any issues.
It is also unclear if there is a good way to prevent future related
bugs since std out is global to the process.

Overview
Pinniped provides identity services to Kubernetes.
Pinniped allows cluster administrators to easily plug in external identity providers (IDPs) into Kubernetes clusters. This is achieved via a uniform install procedure across all types and origins of Kubernetes clusters, declarative configuration via Kubernetes APIs, enterprise-grade integrations with IDPs, and distribution-specific integration strategies.
Example use cases
- Your team uses a large enterprise IDP, and has many clusters that they
manage. Pinniped provides:
- Seamless and robust integration with the IDP
- Easy installation across clusters of any type and origin
- A simplified login flow across all clusters
- Your team shares a single cluster. Pinniped provides:
- Simple configuration to integrate an IDP
- Individual, revocable identities
Architecture
The Pinniped Supervisor component offers identity federation to enable a user to access multiple clusters with a single daily login to their external IDP. The Pinniped Supervisor supports various external IDP types.
The Pinniped Concierge component offers credential exchange to enable a user to exchange an external credential for a short-lived, cluster-specific credential. Pinniped supports various authentication methods and implements different integration strategies for various Kubernetes distributions to make authentication possible.
The Pinniped Concierge can be configured to hook into the Pinniped Supervisor's federated credentials, or it can authenticate users directly via external IDP credentials.
