Deploy universal operators easily with Juju, the Universal Operator Lifecycle Manager.
Platform:
Charmed OpenSearch Tutorial > 2. Deploy OpenSearch
Deploy OpenSearch
To deploy Charmed OpenSearch, all you need to do is run the following command:
Note: Charmed OpenSearch supports performance profile. It is recommended in a single host deployment with LXD to use the testing profile, which will only consume 1G RAM per container.
juju deploy opensearch -n 3 --channel 2/beta --config profile="testing"
Note: The -n flag is optional and specifies the number of units to deploy. In this case, we are deploying three units of Charmed OpenSearch. We recommend deploying at least three units for high availability.
The command will fetch the charm from Charmhub and deploy 3 units to the LXD cloud. This process can take several minutes depending on your machine.
You can track the progress by running:
juju status --watch 1s
This command is useful for checking the status of your Juju model, including the applications and machines it hosts. Helpful information it displays includes IP addresses, ports, state, etc. The output of this command updates once every other second.
When the application is ready, juju status will show something similar to the sample output below:

The status message Waiting for TLS to be fully configured... is displayed because Charmed OpenSearch requires TLS to be configured before use, to ensure data is encrypted in transit for the HTTP and Transport layers. We will do this in the next step.
If you see the following status message:
vm.swappiness should be 0 - net.ipv4.tcp_retries2 should be 5
you need to set the correct kernel parameters to continue.
Next step: 3. Enable TLS
