I want Elasticsearch snapshots named with date and time when they are created.
With the following template snapshot-YYYY-MM-dd_HH-mm-ss
Like this: snapshot-2020-05-25_22-58-13
How this can be done?
Elasticsearch documentation looks absolutely unclear about it, say no words and gives no example about time. I'm using v7.6 of Elasticsearch.
After some experiments I have found a solution. Here is the template that works:
<snapshot-{now{yyyy-MM-dd_HH-mm-ss|Europe/Oslo}}>
Note the time zone at the end. Without explicit time zone indication template generates time in UTC.
Docs from the previous version may shed some light on snapshot naming:
