Some problems on elasticsearch_6.3.1 docker

Elastic Stack Elasticsearch
1

I have installed repository-s3 and modify elasticsearh.yml, But I don't want to restart container
I can't find any way

2

You need to restart if you want the changes made in the config file read.

3

If I only installed repository-s3，must I restart ？

4

I want to backup my data of elasticsearch to s3. I can't restart the cluster,because the cluster is very important for our team.
Can you give me some good ideas? best wishs.

5

Yes.

6

You can do a rolling upgrade hopefully.

7

Should I install repository-s3 on every eslasticsearch server for backupping data of elasticsearch to s3 ?

8

Yes. S3 repository plugin | Elasticsearch Plugins and Integrations [8.11] | Elastic says:

The plugin must be installed on every node in the cluster, and each node must be restarted after installation.
