[ECK] ECK 8.1 ,APM intergration安裝方式

前言

一兩個月沒看，沒想到版本就衝到8.1了，
照以前的做法，發現一堆錯誤，
precondition ‘apm integration installed’ failed: error querying Elasticsearch for integration index templates: unexpected HTTP status: 404 Not Found…

正文

版本升級後，架構變成下圖(1)

所以才導致下圖的錯誤發生，

原因是，ECK升級，

所以統一要先在kibana上面先安裝 APM intergration。

If you install version 8.2.0 of APM Server before installing the APM integration, you will see error logs similar to the following. You must go back and install the APM integration before data can be ingested into Elasticsearch.

ref. Upgrade a self-installation of APM Server standalone to 8.2.0

Step 1.

Step 2.

安裝APM server即可，安裝完後，
選擇 『Add Elastic Agent later'。
