Charmed PostgreSQL K8s Tutorial > 2. Deploy PostgreSQL

Deploy Charmed PostgreSQL K8s

In this section, you will deploy a postgresql-k8s application to your juju model and track its status.


Deploy PostgreSQL

To deploy Charmed PostgreSQL K8s, run

juju deploy postgresql-k8s --trust

--trust is required because the charm and Patroni need to create some K8s resources.

Juju will now fetch Charmed PostgreSQL K8s from Charmhub and deploy it to the local MicroK8s. This process can take several minutes depending on how provisioned (RAM, CPU, etc) your machine is.

Track status

You can track the deployment by running:

juju status --watch 1s

This command is useful for checking the real-time information about the state of a charm and the machines hosting it. Check the juju status documentation for more information about its usage.

When the application is ready, juju status will show something similar to the sample output below:

Model     Controller  Cloud/Region        Version  SLA          Timestamp
tutorial  charm-dev   microk8s/localhost  2.9.42   unsupported  12:00:43+01:00

App             Version  Status  Scale  Charm           Channel    Rev  Address         Exposed  Message
postgresql-k8s           active      1  postgresql-k8s  14/stable  56  no

Unit               Workload  Agent  Address       Ports  Message
postgresql-k8s/0*  active    idle

You can also watch juju logs with the juju debug-log command. More info on logging in the juju logs documentation.
