Get OpenSearch Dashboards up and running
The objective of Opensearch Dashboard is to display the contents of an Opensearch database. This is why a functional Opensearch database is a pre-requisite for the Dashboards application to install successfully.
So, before going further, let’s set up Charmed Opensearch. Note that Opensearch has a mandatory requirement of TLS support, so we need to deploy it alongside the self-signed-certificates charm and integrate (also known as “relate”) them.
Make sure that the environment is ready and the Juju model is correctly configured following instructions in OpenSearch Documentation Set kernel parameters.
Subsequentially we can deploy Opensearch with TLS:
juju deploy opensearch --channel=2/edge -n 2
juju deploy self-signed-certificates
juju relate self-signed-certificates opensearch
We can simply add the Opensearch Dashboards charm to this setup by deploying and relating it to Opensearch
juju deploy opensearch-dashboards --channel=2/edge
juju relate opensearch opensearch-dashboards
And there we go!
Now if you check the status of your services with juju status.
Your output should be similar to the example below:

Note: in case you would like to verify the integrations as well, you can add the flag --relations.
$ juju status --relations
Alternatively, if you want to monitor your system (with a view updating every second):
$ juju status --watch 1s
