S3-repository deprecated settings warning

[dadoonet (David Pilato)]

You should also start using the keystore to store credentials.

Secure Settings | Elasticsearch Reference [5.5] | Elastic

Then add your secure settings as:

s3.client.default.access_key
s3.client.default.secret_key

See

Getting AWS credentials from keystore for discovery-ec2 plugin?

I see. Sadly the documentation has not been updated yet. It needs to be: discovery.ec2.access_key discovery.ec2.secret_key cloud.aws.region should not be used anymore but discovery.ec2.endpoint needs to be set in elasticsearch.yml file. See https://github.com/elastic/elasticsearch/blob/5.4/plugins/discovery-ec2/src/main/java/org/elasticsearch/discovery/ec2/AwsEc2Service.java#L181-L188 I hope this helps. cc @rjernst in case I'm saying something wrong

And

The different keystore settings did affect the result, now able to create bucket. Here is keystore list output: /mnt/elasticsearch# bin/elasticsearch-keystore list discovery.ec2.access_key discovery.ec2.secret_key s3.client.default.access_key s3.client.default.secret_key Here is result of running shell script to create the repository bucket: /mnt/elasticsearch# bin/s3-repo-create.sh es-lineartv_test {"acknowledged":true}
