Memphis.dev is a highly scalable, painless, and effortless data streaming platform.
Made to enable developers and data teams to collaborate and build
real-time and streaming apps fast.
Helm is a k8s package manager that allows users to deploy apps in a single, configurable command.
More information about Helm can be found here.
Memphis is cloud-native and cloud-agnostic to any Kubernetes on any cloud.

a) Generate a self-signed certificate using mkcert
$ mkcert -client \
-cert-file memphis_client.pem \
-key-file memphis-key_client.pem \
"127.0.0.1" "localhost" "*.memphis.dev" ::1 \
email@localhost [email protected]b) Find the rootCA
$ mkcert -CAROOT
c) Create self-signed certificates for client
$ mkcert -client -cert-file client.pem -key-file key-client.pem localhost ::1 a) Create a dedicated namespace for memphis
kubectl create namespace memphisb) Create a k8s secret with the required certs
