Error: [resource_already_exists_exception] index [.kibana_task_manager_2/0L7hFqypSzG1O5FjfcDoqQ] already exists, with { index_uuid=\"0L7hFqypSzG1O5FjfcDoqQ\" & index=\".kibana_task_manager_2\" }"}

我這一天要升級kibana ，從6.8.1升級到7.5.1

這是kibnana 在 頁面出現Kibana is not ready yet之後 ，我去查看到的Log

因為先前的kibana的資料需要Migrate ，你需要等待。

簡單來說，你需要刪除掉在elastic的某個index

就我的狀況，我需要刪除4個

kibana_task_manager_1

kibana_task_manager_2

kibana_1

kibana_2

所以我用Postman 

打delete 方法 curl DELETE http://localhost:9200/.kibana_1
curl DELETE http://localhost:9200/.kibana_task_manager_1

curl DELETE http://localhost:9200/.kibana_2

curl DELETE http://localhost:9200/.kibana_task_manager_2
就可以重新啟動
但是這樣一來，會把原來的dashboard全部刪除，所以要注意
