juju deploy mysql-router-k8s --channel 8.0/stable
Deploy Kubernetes operators easily with Juju, the Universal Operator Lifecycle Manager. Need a Kubernetes cluster? Install MicroK8s to create a full CNCF-certified Kubernetes system in under 60 seconds.
Platform:
Note: All commands are written for juju >= v.3.1
If you’re using juju 2.9, check the juju 3.0 Release Notes.
How to enable TLS encryption
This guide will show how to enable TLS using the self-signed-certificates operator as an example.
Self-signed certificates are not recommended for a production environment.
Check this guide for an overview of the TLS certificates charms available.
Enable TLS
First, deploy the TLS charm:
juju deploy self-signed-certificates
To enable TLS, integrate the two applications:
juju integrate self-signed-certificates mysql-router-k8s
Manage keys
Updates to private keys for certificate signing requests (CSR) can be made via the set-tls-private-key action. Note that passing keys to external/internal keys should only be done with base64 -w0, not cat.
With three replicas, this schema should be followed:
Generate a shared internal (private) key:
openssl genrsa -out internal-key.pem 3072
Apply the newly generated internal key on each juju unit:
juju run mysql-router-k8s/0 set-tls-private-key "internal-key=$(base64 -w0 internal-key.pem)"
juju run mysql-router-k8s/1 set-tls-private-key "internal-key=$(base64 -w0 internal-key.pem)"
juju run mysql-router-k8s/2 set-tls-private-key "internal-key=$(base64 -w0 internal-key.pem)"
Updates can also be done with auto-generated keys with:
juju run mysql-router-k8s/0 set-tls-private-key
juju run mysql-router-k8s/1 set-tls-private-key
juju run mysql-router-k8s/2 set-tls-private-key
Disable TLS
Disable TLS by removing the integration:
