oci-k8s-cache

Oracle Cloud Infrastructure Kubernetes token cache - because no one wants to wait 3s for their API to respond

Installation

cd ~ # make sure that you don't add this binary to your Go Modules project :)
GO111MODULE=on go get -u github.com/pyr-sh/oci-k8s-cache@latest

Make sure that your $GOPATH/bin is in your PATH variable. Alternatively note the full path of the binary and use it directly as the command in your ~/.kube/config.

Usage

After adding an OCI cluster to your ~/.kube/config, change the cluster's user's command to oci-k8s-cache, or the full path to the binary.

Benchmarks

Ran on an i7-5960X from Poland against the us-ashburn-1 cluster.
