ES 6.8.2
Minio S3 VERSION:
2019-10-12T01:39:57Z
I have es cluster running.
When I try to create repo for s3 on minio
with
{
"type": "s3",
"settings": {
"bucket": "elasticsearch-backups",
"endpoint": "dns-name"
}
}

I get

"error" : {
"root_cause" : [
{
"type" : "repository_verification_exception",
"reason" : "[es_snapshot_s3] path is not accessible on master node"
}
],
"type" : "repository_verification_exception",
"reason" : "[es_snapshot_s3] path is not accessible on master node",
"caused_by" : {
"type" : "i_o_exception",
"reason" : "Unable to upload object [tests-KnN5zU85RRmeOSfqPWX1Pg/master.dat] using a single upload",
"caused_by" : {
"type" : "sdk_client_exception",
"reason" : "Unable to execute HTTP request: elasticsearch-backups.dns-name",
"caused_by" : {
"type" : "unknown_host_exception",
"reason" : "elasticsearch-backups.dns-name"
}
}
}
},
"status" : 500
}

because there is no elasticsearch-backups.dns-name dns A record

These is path_style_access option but I am not sure that it is available in 6.8.2 version ES.
Can someone clarify?

Hi @Sergey_Mucha

@Sergey_Mucha

These is path_style_access option but I am not sure that it is available in 6.8.2 version ES.

I'm afraid forcing path style access was only introduced in v7, see relevant PR here:

#31608 Add S3 Setting to Force Path Type Access

Could you maybe set an IP for the endpoint? That would be a workaround that would force the SDK to use path style access.

@Armin_Braun

Could you maybe set an IP or the endpoint?

I set endpoint, not sure that I get what you mean for endpoint.

@Sergey_Mucha

I set endpoint, not sure that I get what you mean for endpoint.

Sorry that was the worst possible typo What I meant to write was that you should set an actual IP address for the endpoint, not a DNS name if that is possible.

Ok. Now I get. hahaha. I used ip, but sometimes s3 will be with dnsname - it will require updates for s3 in case it use ssl(include ip address to alternative name).
Anyway thanks for clarification.
