Deploy Memphis over Kubernetes
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.

Production-ready Memphis deployment with initial three memphis brokers configured in cluster mode for high availability and higher throughput.
Stable release
helm repo add memphis https://k8s.memphis.dev/charts/ --force-update && helm install memphis memphis/memphis --set global.cluster.enabled="true" --create-namespace --namespace memphis --wait
Latest release
helm repo add memphis https://k8s.memphis.dev/charts/ --force-update && helm install --set global.cluster.enabled="true" memphis memphis/memphis --create-namespace --namespace memphis --wait
Minimal deployment of Memphis with a single broker
Stable release
helm repo add memphis https://k8s.memphis.dev/charts/ --force-update && helm install memphis memphis/memphis --create-namespace --namespace memphis --wait
Latest release
helm repo add memphis https://k8s.memphis.dev/charts/ --force-update && helm install memphis memphis/memphis --create-namespace --namespace memphis --wait
Here is how to run an installation command with additional options -
helm install memphis --set cluster.replicas=3,memphis.creds.rootPwd=rootpassword" memphis/memphis --create-namespace --namespace memphis
- memphis. Memphis broker.
- memphis-rest-gateway. Memphis REST Gateway.
- memphis-metadata. Metadata store.
- memphis-metadata-coordinator. Metadata coordinator
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 memphis
b) Create a k8s secret with the required certs
1
kubectl create secret generic memphis-client-tls-secret \

--from-file=memphis_client.pem \

- 1.Create a k8s secret with the provided TLS certs
kubectl create secret generic memphis-client-tls-secret \
--from-file=memphis_client.pem \
--from-file=memphis-key_client.pem \
--from-file=rootCA.pem -n memphis
- 2.Upgrade Memphis to use the TLS certs
helm repo add memphis https://k8s.memphis.dev/charts/ --force-update
helm upgrade memphis memphis/memphis -n memphis --reuse-values \
--set \
memphis.tls.verify="true",\

Red Hat OpenShift
To deploy the Memphis cluster on top of Red Hat Openshift it's necessary to configure default security context parameters as follows:
helm repo add memphis https://k8s.memphis.dev/charts/ --force-update &&
helm install memphis memphis/memphis --set \
global.cluster.enabled="true",\
metadata.postgresql.containerSecurityContext.enabled="false",\
metadata.postgresql.podSecurityContext.enabled="false",\
metadata.pgpool.containerSecurityContext.enabled="false",\
metadata.pgpool.podSecurityContext.enabled="false" \
--create-namespace --namespace memphis --wait
