From your error log, it seems that the elasticsearch cluster has a security setup to prevent unauthorised access from your k8s cluster. The
AuthenticationExceptionis a clear indication.I'd advise to start by testing connectivity outside of Airflow to narrow down the root cause. For example, try running a standalone Python script inside the same Kubernetes cluster that hosts your Airflow environment. In that script, use the official [elasticsearch-py] (https://github.com/elastic/elasticsearch-py) client library to connect to your Elasticsearch cluster and try to do sth like
es_client.ping(). Make sure to experiment with SSL-related parameters such as ssl_verify and ca_certs until you can reliably connect.Once you've confirmed that your Python script can successfully interact with Elasticsearch, you can mirror those working configurations in your airflow.cfg (e.g., adjusting the Elasticsearch configuration sections) and restart Airflow
Hello @Owen-CH-Leung,
Thank you for your response.
The cluster is accessible from the outside, and some pipelines already successfully send data to Elasticsearch using elasticsearch-py.
However, the error logs suggest that Airflow is not transmitting the authentication parameters:
missing authentication credentials for REST requestThe elasticsearch_default connection has already been created, so I’m wondering if there might be a workaround to ensure Airflow sends the authentication details to Elasticsearch properly?
Thank you
You can define the credentials in
elasticsearch_configssession in your airflow cfg.In the
elasticsearch_configssession, you can pass in any parameters that elasticsearch client accepts. Example:[elasticsearch_configs] http_compress = True ca_certs = /root/ca.pem api_key = "SOMEAPIKEY" verify_certs = TrueAll the params you define will be passed into the elasticsearch python library like
elasticsearch.Elasticsearch(**kwargs)Reacted by julien lagorsse, benjamin-dinh and kamaralThanks, it solved the issue, but we are still blocked after that, the data isn't push, however we can see pull of logs. We will create another issue for that. Thank you
The doc seems to be missleading, the title is Writing logs to Elasticsearch but it doesn't write anything to Elasticsearch, only read.
The doc seems to be missleading, the title is Writing logs to Elasticsearch but it doesn't write anything to Elasticsearch, only read.
Actually not really - It's about both writing (and then reading the logs. If you read the first paragraph (that's the first time I see the docs). The docs say that you can get the logs from stdout and forward them (write) to elasticsearch by
fluentd, logstash or others.Airflow can be configured to read task logs from Elasticsearch and optionally write logs to stdout in standard or json format. These logs can later be collected and forwarded to the Elasticsearch cluster using tools like fluentd, logstash or others.
Are you doing it @julienlagorsse-loreal ? Maybe that is the problem that you are not forwarding the stdout logs to elasticsearch?
- We have issues on file share with k8s, anyway it's not related to the bug, but the title is clearly misleading, it say write logs to elastic, not read logs from elastic or write logs to stdout ... But I agree the doc paragraph is not.

Apache Airflow version

What happened?
Hello all, hope you doing well.
While trying to send logs to elasticsearch directly threw the elastic adapter (inside airflow conf), it does not work.
--> today we pass threw file share (azure) mounted as PV inside K8S, then logstash pipeline, but it costs a lots per years ...
I think the adapter is broken, even when trying to test a connection directly inside the webserver, we have an error :
'ESConnection' object has no attribute 'close'Then when trying to send logs to elasticsearch, it does not try to send logs and it cannot connect to the elasticsearch when trying to get back logs.
Anyway, while trying to look for logs inside a DAG we also have this error :
elasticsearch.AuthenticationException: AuthenticationException(401, 'security_exception', 'missing authentication credentials for REST request [/airflow-logs-*/_count]') airflow-webserver-1 | 172.18.0.1 - - [06/Dec/2024:11:26:46 +0000] "GET /api/v1/dags/debug_airflow_to_elastic/dagRuns/manual__2024-12-06T11:26:37.042642+00:00/taskInstances/print_debug_message/logs/1?full_content=false HTTP/1.1" 500 1588 "http://localhost:8080/dags/debug_airflow_to_elastic/grid?dag_run_id=manual__2024-12-06T11%3A26%3A37.042642%2B00%3A00&task_id=print_debug_message&tab=logs" "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/131.0.0.0 Safari/537.36"But the I tried with an api key, user password and even both but cannot get rid of it.
I think there is a bug around it or did we do something wrong.
Thousands thanks !

What you think should happen instead?
No response
How to reproduce
Just add a connection to elasticsearch, try to connect to it.
Then add remote logging inside conf.
It does not try to send logs and it cannot connect to the elasticsearch.
Operating System
Kubernetes and docker compose. (both d'ont work)
Versions of Apache Airflow Providers
No response
Deployment
Official Apache Airflow Helm Chart
