prefix in objstoreConfig not working

[hesanjea]

Hi,
sorry if this is a silly question but I am trying to deploy thanos using the bintnami chart and when trying to configure a prefix as follows:
objstoreConfig:
type: S3
config:
bucket: "bucket-namet"
endpoint: "s3.eu-west-1.amazonaws.com"
region: ""
aws_sdk_auth: false
access_key: ""
insecure: false
signature_version2: false
secret_key: ""
put_user_metadata: {}
http_config:
idle_conn_timeout: 1m30s
response_header_timeout: 2m
insecure_skip_verify: false
tls_handshake_timeout: 10s
expect_continue_timeout: 1s
max_idle_conns: 100
max_idle_conns_per_host: 100
max_conns_per_host: 0
tls_config:
ca_file: ""
cert_file: ""
key_file: ""
server_name: ""
insecure_skip_verify: true
trace:
enable: false
list_objects_version: ""
part_size: 67108864
sse_config:
type: ""
kms_key_id: ""
kms_encryption_context: {}
encryption_key: ""
sts_endpoint: ""
prefix: "thanos_metrics"

I am getting this error:

level=error ts=2022-06-24T08:14:54.625680723Z caller=main.go:132 err="yaml: unmarshal errors:\n line 36: field prefix not found in type client.BucketConfig\nparsing config YAML file\ngithub.com/thanos-io/thanos/pkg/objstore/client.NewBucket\n\t/app/pkg/objstore/client/factory.go:52\nmain.runReceive\n\t/app/cmd/thanos/receive.go:161\nmain.registerReceive.func1\n\t/app/cmd/thanos/receive.go:86\nmain.main\n\t/app/cmd/thanos/main.go:130\nruntime.main\n\t/usr/local/go/src/runtime/proc.go:255\nruntime.goexit\n\t/usr/local/go/src/runtime/asm_amd64.s:1581\npreparing receive command failed\nmain.main\n\t/app/cmd/thanos/main.go:132\nruntime.main\n\t/usr/local/go/src/runtime/proc.go:255\nruntime.goexit\n\t/usr/local/go/src/runtime/asm_amd64.s:1581"

I can't tell what your indentation is but you probably have something like:

type: S3
config:
  bucket: "mybucket"
  . . . 
  prefix: "thanos_metrics"

Prefix is at the root level in the config hierarchy, so it should be:

type: S3
config:
  bucket: "mybucket"
  . . . 
prefix: "thanos_metrics"

Try that.

Thank you @crockk , I'm using the indentation as explained in Thanos doc ("prefix" at the same level than "type" and "config").

upgrade thanos to v0.28.0 will fix it.
