With Mirrord you can intercept traffic for your pods in your Kubernetes cluster, which allows you to develop your application locally as if it was deployed in your cluster. Utilizing the pods network, environment or even the filesystem. In this post I will be writing some examples that I personally use.
You can extend Kubernetes with your own custom objects, but before you can do that you will need create a Custom Resource Definition so that Kubernetes knows what the object is allowed to look like. In this post I will create a very simple Kubernetes CRD for a Book kind using Rust and kube-rs.
Using a Google service account in your GKE cluster is easy, just create the credential file, apply it as a secret and it's ready for use. But now you have a long lived credential that, if compromised, can be used from anywhere any time. Instead you can use a Kubernetes service account and Google Workload Identity to authenticate to Google Cloud. No need for credential files anymore.
In this post I will use OpenSSL to create a Certificate Authority key pair, a certificate private key with a Certificate Signing Request with Subject Alternate Names and lastly I will sign the CSR with the CA.
