How to deploy on MicroK8s
This guide assumes you have a running Juju and MicroK8s environment.
For a detailed walkthrough of setting up an environment and deploying the charm on MicroK8s, refer to the following Tutorial pages:
- 1. Set up the environment - set up Multipass and Juju
- 2. Deploy PostgreSQL - deploy PostgresQL K8s in a Multipass instance
MicroK8s can be installed on a multitude of platforms and environments for different use cases. See all options and details in the official documentation.
Not all platforms supported by MicroK8s will work with this charm - keep in mind the system requirements of Charmed PostgreSQL.
Prerequisites
- Canonical MicroK8s 1.27+
- Fulfill the general system requirements
Bootstrap a juju controller and create a model if you haven’t already:
juju bootstrap localhost <controller name>
juju add-model <model name>
Deploy PostgreSQL K8s:
juju deploy postgresql-k8s --trust
The --trust flag is necessary to create some K8s resources
See the
juju deploydocumentation for all available options at deploy time.See the Configurations tab for specific PostgreSQL K8s parameters.
Example juju status --wait 1s output:
