Hello everyone! I have a little question about the elasticsearch-node tool: Is it possible to use it in any way to detach a node from a cluster that exists in a docker container? So far the tool throws an exception that a node cannot be detached if it is still running, which sounds reasonable. I tried shutting down the node inside the container, but it results in the container being shut down. Thanks in advance for your answers! ---

If you have lost all masters then you have lost the cluster, there is no recovering unless you have a backup. ---

But all my data nodes are still alive. And i suppose that this command can help to me to add my fata node to new mater node. "elasticsearch-node detach-cluster" ---

You cannot attach a data node to a new master. If you have lost all master nodes and can not bring them back up you need to recreate the cluster and restore data from a snapshot. ---

I don't have any backup. And this article says me that i can try to restore my data > **[elasticsearch-node | Elasticsearch Guide \[7.12\] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/node-tool.html#node-tool-detach-cluster)** But i can't run this command from docker container. ---

Can't you attach to the container in order to run the command? ---

To run command i need stop elasticsearch service. But when i stopping service docker container is closed... ---

Ah yes, that is true. Then I do not think you can recover the data in the cluster. ---

``` docker run --name detach -p 9200:9200 -p 9300:9300 -v /your_volume_with_elastic_data -v /your__elastic_config -it **--entrypoint /bin/bash** elasticsearch:7.10.1 ``` This right command to run docker. After that you can run bin/elasticsearch-nodes detach-cluster or other similar commands. ---
