<p>I am trying to setup remote logging in Airflow <code>stable/airflow</code> helm chart on  <code>v1.10.9</code> I am using <strong>Kubernetes executor</strong> and <code>puckel/docker-airflow</code> image. here's my <code>values.yaml</code> file.</p>

<pre><code>airflow:
  image:
     repository: airflow-docker-local
     tag: 1.10.9
  executor: Kubernetes
  service:
    type: LoadBalancer
  config:
    AIRFLOW__KUBERNETES__WORKER_CONTAINER_REPOSITORY: airflow-docker-local
    AIRFLOW__KUBERNETES__WORKER_CONTAINER_TAG: 1.10.9
    AIRFLOW__KUBERNETES__WORKER_CONTAINER_IMAGE_PULL_POLICY: Never
    AIRFLOW__KUBERNETES__WORKER_SERVICE_ACCOUNT_NAME: airflow
    AIRFLOW__KUBERNETES__DAGS_VOLUME_CLAIM: airflow
    AIRFLOW__KUBERNETES__NAMESPACE: airflow
    AIRFLOW__CORE__REMOTE_LOGGING: True
    AIRFLOW__CORE__REMOTE_BASE_LOG_FOLDER: "s3://xxx"
    AIRFLOW__CORE__REMOTE_LOG_CONN_ID: "s3://aws_access_key_id:aws_secret_access_key@bucket"
    AIRFLOW__CORE__ENCRYPT_S3_LOGS: False
persistence:
  enabled: true
  existingClaim: ''
postgresql:
  enabled: true
workers:
  enabled: false
redis:
  enabled: false
flower:
  enabled: false
</code></pre>

<p>but my logs don't get exported to S3, all I get on UI is</p>

<pre><code>*** Log file does not exist: /usr/local/airflow/logs/icp_job_dag/icp-kube-job/2019-02-13T00:00:00+00:00/1.log

</code></pre>

<p>any one have more insights what could I be missing? </p>

<p><strong>Edit:</strong> from @trejas's suggestion below. I created a separate connection and using that. here's what my airflow config in <code>values.yaml</code> look like</p>

<pre><code>airflow:
  image:
     repository: airflow-docker-local
     tag: 1.10.9
  executor: Kubernetes
  service:
    type: LoadBalancer
  connections:
  - id: my_aws
    type: aws
    extra: '{"aws_access_key_id": "xxxx", "aws_secret_access_key": "xxxx", "region_name":"us-west-2"}'
  config:
    AIRFLOW__KUBERNETES__WORKER_CONTAINER_REPOSITORY: airflow-docker-local
    AIRFLOW__KUBERNETES__WORKER_CONTAINER_TAG: 1.10.9

    AIRFLOW__KUBERNETES__WORKER_SERVICE_ACCOUNT_NAME: airflow
    AIRFLOW__KUBERNETES__DAGS_VOLUME_CLAIM: airflow
    AIRFLOW__KUBERNETES__NAMESPACE: airflow

    AIRFLOW__CORE__REMOTE_LOGGING: True
    AIRFLOW__CORE__REMOTE_BASE_LOG_FOLDER: s3://airflow.logs

    AIRFLOW__CORE__ENCRYPT_S3_LOGS: False
</code></pre>

<p>I still have the same issue.</p>

<p>I was running into the same issue and thought I'd follow up with what ended up working for me. The connection is correct but you need to make sure that the worker pods have the same environment variables:</p>

<pre><code>airflow:
  image:
     repository: airflow-docker-local
     tag: 1.10.9
  executor: Kubernetes

    type: aws
    extra: '{"aws_access_key_id": "xxxx", "aws_secret_access_key": "xxxx", "region_name":"us-west-2"}'
  config:
    AIRFLOW__KUBERNETES__WORKER_CONTAINER_REPOSITORY: airflow-docker-local

    AIRFLOW__KUBERNETES_ENVIRONMENT_VARIABLES__AIRFLOW__CORE__ENCRYPT_S3_LOGS: False

</code></pre>

<p>I also had to set the fernet key for the workers (and in general) otherwise I get an invalid token error:</p>

<pre><code>airflow:
  fernet_key: "abcdefghijkl1234567890zxcvbnmasdfghyrewsdsddfd="

  config:
    AIRFLOW__KUBERNETES_ENVIRONMENT_VARIABLES__AIRFLOW__CORE__FERNET_KEY: "abcdefghijkl1234567890zxcvbnmasdfghyrewsdsddfd="
</code></pre>
