How to integrate with COS
prometheus-k8s
Deploy and relate prometheus-k8s charm with wordpress-k8s
charm through the metrics-endpoint relation via prometheus_scrape interface. Prometheus should
start scraping the metrics exposed at :9117/metrics endpoint.
juju deploy prometheus-k8s
juju integrate wordpress-k8s prometheus-k8s
loki-k8s
Deploy and relate loki-k8s charm with wordpress-k8s charm through
the logging relation via loki_push_api interface. Promtail worker should spawn and start pushing
Apache access logs and error logs to Loki.
juju deploy loki-k8s
juju integrate wordpress-k8s loki-k8s
grafana-k8s
In order for the Grafana dashboard to function properly, Grafana should be able to connect to
Prometheus and Loki as its datasource. Deploy and relate the prometheus-k8s and loki-k8s
charms with grafana-k8s charm through the grafana-source integration.
Note that the integration grafana-source has to be explicitly stated since prometheus-k8s and
grafana-k8s share multiple interfaces.
juju deploy grafana-k8s
juju integrate prometheus-k8s:grafana-source grafana-k8s:grafana-source
juju integrate loki-k8s:grafana-source grafana-k8s:grafana-source
Then, the wordpress-k8s charm can be related with Grafana using the grafana-dashboard relation with
grafana_dashboard interface.
juju integrate wordpress-k8s grafana-k8s
To access the Grafana dashboard for the WordPress charm, run the get-admin-password action
to obtain credentials for admin access.
juju run grafana-k8s/0 get-admin-password
Log into the Grafana dashboard by visiting http://<grafana-unit-ip>:3000. Navigate to
http://<grafana-unit-ip>:3000/dashboards and access the WordPress dashboard named Wordpress Operator
