Juju version

The charm supports both Juju 2.9 LTS and Juju 3.x, however charm revisions may require different Juju versions. Always check the charm release notes to find the minimal Juju version for your deployment.

Kubernetes requirements

  • Kubernetes 1.27+
  • Canonical MicroK8s 1.27+ (snap channel 1.27-strict/stable and newer)

Minimum requirements

Make sure your machine meets the following requirements:

  • Ubuntu 22.04 (Jammy) or later.
  • 8GB of RAM.
  • 2 CPU threads.
  • At least 20GB of available storage.
  • Access to the internet for downloading the required OCI/ROCKs and charms.

Supported architectures

The charm is based on ROCK OCI named “charmed-mysql”, which is recursively based on SNAP “charmed-mysql”, which is currently available for amd64 only! The architecture arm64 support is planned. Please contact us if you are interested in new architecture!

MySQL Group Replication requirements

  • In order to integrate with this charm, every table created by the integrated application must have a primary key. This is required by the group replication plugin enabled in this charm.
  • the count of Charmed MySQL K8s units in a single Juju application is limited to 9. Unit 10+ will start; however, they will not join the cluster but sleep in a hot-swap reserve.
