Portainer BE 2.10 added custom template support for Kubernetes environments, allowing you to create templates based on Kubernetes manifests for future deployment.
From the menu select Custom Templates to view a list of custom templates you've already created.
You can create a new template.
{% content-ref url="add.md" %} add.md {% endcontent-ref %}
You can also edit an existing template.
{% content-ref url="edit.md" %} edit.md {% endcontent-ref %}
And, if you no longer need a custom template, you can simply remove it.
{% content-ref url="remove.md" %} remove.md {% endcontent-ref %}
