TLS - Memphis TLS websocket configuration

In this tutorial, you will discover the steps to enable Memphis's built-in Websocket service and generate self-signed certificates to enhance server security.

Create self-signed certificates

Before securing your Memphis deployments, you need to create self-signed certificates. This section provides instructions for generating the necessary certificates.

  • Create self-signed certificates for the Memphis server using mkcert. These certificates are essential for securing the server:

$ mkcert \
-cert-file memphis.pem \
-key-file memphis-key.pem  \
  • Next, create a secret resource in the memphis namespace to store these certificates. You can use the following command:

kubectl create secret generic tls-secret \
--from-file=memphis.pem --from-file=memphis-key.pem -n memphis
  • With your self-signed certificates in place, you can deploy Memphis with Websocket support using Helm in a single-line command. Ensure that Websocket communication is enabled and provide the certificate information as follows:

helm install my-memphis memphis \
--create-namespace --namespace memphis --wait \
--set \

Note: The global.cluster.enabled configuration, omitted in this command, is intended for situations in which Memphis is deployed within a cluster environment. Ensure that you activate it as necessary when configuring deployments as a cluster.
