Indices rule not working for data stream ES 7.17
Elastic and Kibana 7.17.1
RoR Pro 1.39.0 and 1.40.0 (both tested)

According to this thread this issue has been fixed in 1.39.0 changelog
It works with a rule without indices :
- name: '::B16a-myrule::'
actions:
- indices:data/read/*
- cluster:monitor/main
groups:
- mygroup
type: allow
verbosity: info

Yes, same behavior with 1.41.0. I have this empty response for GET /logs-example*/_search :
{"took":1,"timed_out":false,"_shards":{"total":0,"successful":0,"skipped":0,"failed":0},"hits":{"total":{"value":0,"relation":"eq"},"max_score":0.0,"hits":[]}}
It works when I specify the exact name of the data stream : GET /logs-example-202206/_search
And with the rule :
- name: '::B16a-myrule::'
actions:
- indices:data/read/*
- cluster:monitor/main
groups:
- mygroup
indices:
- 'logs-example*'
type: allow

HI @mlollo
Yes, I can confirm it was fixed. We have automated tests for this, so the regression is not very likely.
Did you check what you get without ROR installed (or with ROR disabled)? Could you please show us a list of your indices (and data streams) and aliases, please?
indices rule has rich debug logs support. You can enable debug logs and show us the logs related to the HTTP request
Thank you for your response I tried to enable debug logs :

There is no alias found for the data stream, I think by default the elasticsearch managed index template logs doesn't create aliases required for ROR indices rule to work (I didn't understood at the beginning that data stream are not the same as aliases). This is why it doesn't match any indices or aliases.

For now I have a workaround with this rule (with .ds-logs-example* pattern) :
- name: '::B16a-myrule::'
actions:
- indices:data/read/*
- cluster:monitor/main
groups:
- mygroup
indices:
- '.ds-logs-example*'
type: allow
verbosity: info
This request works GET /.ds-logs-example*/_search
If I need to make the rule works with aliases I would need to do for each new data stream YYYYMM :
POST _aliases
{
"actions": [
{
"add": {
"index": "logs-example*",
"alias": "logs-example"
}
}
]
}
With the block :
- name: '::B16a-myrule::'
actions:
- indices:data/read/*
- cluster:monitor/main
groups:
- mygroup
indices:
- 'logs-example*'
type: allow
verbosity: info
This request works GET /logs-example*/_search
For me you can close the issue, the answer is : indices ror rule match only indices and aliases not data stream.
Hi,
I face a very similar issue as @mlollo , with Elasticsearch 7.17 and RoR 1.41.
In summary,
- It works to give indices:data/read/* permission to a user on a datastream if the request contains the full name of the data stream:
GET mydatastreamAAA/_search
{
"query": {
"match_all": {}
}
}
RESPONSE:
{
"took" : 2,
"timed_out" : false,
"_shards" : {
"total" : 1,
"successful" : 1,
"skipped" : 0,
"failed" : 0
},
"hits" : {
"total" : {
"value" : 372,
"relation" : "eq"
},...
- However, the same request with a data stream name that includes a * returns nothing:
GET mydatastream*/_search
{
"query": {
"match_all": {}
}
}
RESPONSE
{
"took" : 0,
"timed_out" : false,
"_shards" : {
"total" : 0,
"successful" : 0,
"skipped" : 0,
"failed" : 0
},
"hits" : {
"total" : {
"value" : 0,
"relation" : "eq"
},
"max_score" : 0.0,
"hits" : [ ]
}
}
- If I bypass readonlyrest, the above request gives me results.
- It seems to me that readonlyrest doesn't support two levels of resolution (when there's a wildcard index name that matches datastream, or an alias that matches data stream)
Hi Guys. I can confirm there is an issue and it looks like we know the reason. Currently, we are integrating with ES 8.3.x, but when it's finished, we will fix this issue. Thanks for your reports!
@benqua @mlollo are you guys Enterprise subscribers? Trying to organise the priority of our tasks. If yes, please tell me privately on the forum
@mlollo @benqua we have a fix for this issue. If you are interested in testing the pre-build, please let us know what ES version you use. The fix will be released with ROR 1.47.0
