I see a podTemplate definition amongst the contents of elasticsearch.yml. It relies on a set of Custom Resource Definitions (CRD) to declaratively define the way each application is deployed. Cluster does not accept writes, shards may be missing or master This provides the highest safety, but at the cost of the highest amount of disk required and the poorest performance. Will see you next time. For example, assume you have a file named eck-config.yaml with the following content: The operator can be started using any of the following methods to achieve the same end result: If you use a combination of all or some of the these methods, the descending order of precedence in case of a conflict is as follows: You can edit the elastic-operator ConfigMap to change the operator configuration. While undocumented, previously [elasticsearch] log_id supported a Jinja templated string. Once the controller is deployed to your cluster, it will automatically create the CustomResourceDefinition (CRD). If you want volume mount you Preferably you should allocate as much as possible, up to 64Gi per Pod. Then, using the public key injected at the compilation stage, the License is checked for signature, and if it passes, a specific Secret (Cluster Name with a fixed suffix) containing the License is created for the ElasticSearch CR. To review, open the file in an editor that reveals hidden Unicode characters. Like many declarative Api-based implementations of the Operator, the focus of the Elastic Operator revolves around the Reconcile function.
