Based on the knowledge sources provided, I can answer your questions about the role of MinIO in Airbyte and how to manage its storage: 1. Role of MinIO pod in Airbyte: MinIO is primarily used for log storage in Airbyte. According to a [forum post explaining Airbyte pods](https://discuss.airbyte.io/t/1944), MinIO is described as "for logs storage". It stores logs from sync jobs and other Airbyte operations. 2. Increasing storage for MinIO: You can increase the storage for MinIO by modifying the

volumeClaimValue

in your Helm chart's

values.yaml

file. However, be aware that simply changing this value may not immediately apply to an existing deployment. According to a [Github issue about ignored MinIO storage values](https://github.com/airbytehq/airbyte/issues/43357), you might need to delete the existing PersistentVolumeClaim (PVC) and allow it to be recreated with the new size. 3. Automatically deleting logs: Airbyte does have a mechanism for automatically cleaning up old logs. As of version 0.40.5 and later, you can configure the retention period for logs using the

TEMPORAL_HISTORY_RETENTION_IN_DAYS

environment variable. According to a [forum post about Airbyte log sweeping](https://discuss.airbyte.io/t/2714), you can set this to retain logs for only 3 days by adding the following to your environment configuration:

TEMPORAL_HISTORY_RETENTION_IN_DAYS=3

This setting will cause Airbyte to automatically clean up files from the workspace every 3 days, which should help manage your MinIO storage usage. If you're using an older version of Airbyte, you might need to upgrade to take advantage of this feature. Alternatively, for a manual approach, you can delete old logs directly from the MinIO storage as suggested in another [forum post about cleaning up MinIO storage](https://discuss.airbyte.io/t/3101). However, the automatic cleanup method is generally preferred for ongoing maintenance. Remember to always backup your data before making changes to storage configurations or performing manual cleanups.

Based on the knowledge sources provided, I can explain the difference between the

airbyte-dev-logs

and

airbyte-storage

folders within the MinIO pod's storage folder: 1. `airbyte-dev-logs`: This folder is typically used for storing logs in the default MinIO configuration. However, you mentioned that this folder is empty in your case. This could be due to a custom configuration or a change in recent versions of Airbyte. 2. `airbyte-storage`: This folder seems to be the active storage location for Airbyte logs and workload data. You mentioned it contains

job-logging

and

workload

folders, which aligns with Airbyte's storage structure. The difference in usage between these folders might be due to changes in Airbyte's configuration or version. According to a [forum post about MinIO storage](https://discuss.airbyte.io/t/3101), the job logs are typically stored in the path

/storage/airbyte-storage/job-logging/workspace/

. It's worth noting that in some configurations, as mentioned in a [Github issue about worker configuration](https://github.com/airbytehq/airbyte/issues/18016), the storage buckets can be configured using environment variables:

STORAGE_BUCKET_ACTIVITY_PAYLOAD: airbyte-storage STORAGE_BUCKET_LOG: airbyte-storage STORAGE_BUCKET_STATE: airbyte-storage STORAGE_BUCKET_WORKLOAD_OUTPUT: airbyte-storage

This configuration suggests that

airbyte-storage

is indeed the intended location for various types of data, including logs and workload outputs. The empty

airbyte-dev-logs

folder might be a remnant from an older configuration or a placeholder for development environments. If you're not seeing any data there, it's likely that your current Airbyte setup is configured to use the

airbyte-storage

folder exclusively. If you need to manage or clean up the logs, you should focus on the

airbyte-storage/job-logging

directory, as this is where the active log data is being stored in your setup.

Based on the knowledge sources provided, I can guide you on how to clean up the

airbyte-storage/job-logging

directory after executing into the MinIO pod: 1. First, you need to exec into the MinIO pod. You can do this using the following command:

kubectl exec -it -n airbyte airbyte-minio-0 -- /bin/bash

This command is derived from the [Github issue about S3 destination](https://github.com/airbytehq/airbyte/issues/21375). 2. Once you're inside the pod, navigate to the storage directory:

cd /storage/airbyte-storage/job-logging

3. To clean up the directory, you can use standard Linux commands to delete files. For example, to delete all files older than 3 days, you could use:

find . -type f -mtime +3 -delete

This command will find and delete all files that are more than 3 days old. However, it's important to note that manually cleaning up logs is not the recommended approach for long-term maintenance. As mentioned in a [forum post about cleaning up MinIO storage](https://discuss.airbyte.io/t/3101), a more sustainable solution would be to configure Airbyte to automatically manage log retention. For automatic cleanup, you should consider setting the

TEMPORAL_HISTORY_RETENTION_IN_DAYS

environment variable in your Airbyte configuration. This will cause Airbyte to automatically clean up old logs, reducing the need for manual intervention. Remember to be cautious when deleting files manually, as you might accidentally remove important data. Always ensure you have backups before performing any cleanup operations.

I apologize for the confusion in my previous response. You're correct that the

find

command may not be available in the MinIO pod, as it typically runs a minimal container image. Based on the knowledge sources provided, here's a more appropriate way to clean up the

airbyte-storage/job-logging

directory after executing into the MinIO pod: 1. First, exec into the MinIO pod as mentioned before:

kubectl exec -it -n airbyte airbyte-minio-0 -- /bin/bash

2. Once inside the pod, navigate to the storage directory:

cd /storage/airbyte-storage/job-logging

3. Since MinIO uses a minimal container image, you'll need to use basic shell commands to clean up. You can use the

ls

command to list files and directories, and then use

rm

to remove them. For example:

ls -l rm -rf *

This will list the contents of the directory and then remove all files and subdirectories. However, it's important to note that manually cleaning up logs like this is not recommended as a long-term solution. As mentioned in the [forum post about cleaning up MinIO storage](https://discuss.airbyte.io/t/3101), a better approach is to configure Airbyte to automatically manage log retention. For a more sustainable solution, consider setting the

TEMPORAL_HISTORY_RETENTION_IN_DAYS

environment variable in your Airbyte configuration. This will cause Airbyte to automatically clean up old logs, reducing the need for manual intervention. Remember to be extremely cautious when manually deleting files, as you might accidentally remove important data. Always ensure you have backups before performing any cleanup operations.

Based on the knowledge sources provided, I can address your questions about setting up

TEMPORAL_HISTORY_RETENTION_IN_DAYS

and its effect on MinIO log cleanup: 1. How MinIO pod will clean up older files/logs: The

TEMPORAL_HISTORY_RETENTION_IN_DAYS

variable is not directly related to MinIO's operation. Instead, it's used by Airbyte's internal processes to manage log retention. Airbyte will use this setting to determine which logs should be deleted, and it will handle the cleanup process internally. 2. Restarting MinIO or deleting StatefulSet and PVC: You don't need to restart the MinIO StatefulSet or delete and recreate the PVC. The log retention setting is handled by Airbyte's internal processes, not by MinIO directly. 3. How the change takes effect: When you set

TEMPORAL_HISTORY_RETENTION_IN_DAYS

in your

values.yaml

file and run the

helm upgrade --install

command, the new configuration will be applied to the Airbyte deployment. According to the [documentation on configuring Airbyte](https://docs.airbyte.com/operator-guides/configuring-airbyte#data-retention), this variable defines the retention period of the job history in Temporal, which defaults to 30 days if not set. The change should take effect after the Helm upgrade is complete and the Airbyte components have restarted with the new configuration. Airbyte's internal processes will then use this setting to manage log retention going forward. It's important to note that this setting won't immediately delete old logs. Instead, it will prevent new logs from being retained beyond the specified period. The cleanup process will happen gradually as part of Airbyte's regular operations. If you want to verify that the setting has been applied correctly, you can check the environment variables of the relevant Airbyte pods after the upgrade. You should see the

TEMPORAL_HISTORY_RETENTION_IN_DAYS

variable set to your specified value. Remember that while this setting helps manage log retention, it's still a good practice to monitor your MinIO storage usage over time to ensure it aligns with your expectations and storage capacity.

Based on the knowledge sources provided, I don't have specific information on how to create only the MinIO pod with a fresh PVC without affecting other Airbyte components in Kubernetes. The available information doesn't cover this particular scenario. However, I can provide some general guidance based on Kubernetes best practices: 1. You would typically need to modify the Helm chart or create a separate Helm chart just for MinIO deployment. 2. You'd need to create a new PersistentVolumeClaim (PVC) for MinIO. 3. You'd then need to update the MinIO StatefulSet to use this new PVC. 4. Finally, you'd need to update any references in other Airbyte components to point to this new MinIO instance. Given the complexity of this operation and the potential for disrupting your existing Airbyte deployment, I would strongly recommend: 1. Backing up all your data before attempting any changes. 2. Testing this process in a non-production environment first. 3. Consulting with Airbyte's official documentation or support channels for the most up-to-date and safe method to achieve this. If you need specific steps or commands to perform this operation, I'm afraid I don't have enough information in the provided knowledge sources to give you accurate instructions. It would be best to seek advice from Airbyte's official support channels or documentation for such a specific operational task.

Based on the knowledge sources provided, I can offer some insights on deleting the airbyte-minio pod: Yes, you can delete the airbyte-minio pod directly using kubectl, and the StatefulSet will launch a new pod to replace it. This is because StatefulSets in Kubernetes are designed to maintain a stable set of pod identities and persistent storage. However, there are some important considerations: 1. Deleting the pod will not delete the underlying Persistent Volume Claim (PVC) associated with it. As mentioned in a [Github issue about helm delete behavior](https://github.com/airbytehq/airbyte/issues/18591), when you delete pods, the PVCs remain:

$ kubectl delete -l <http://app.kubernetes.io/instance=airbyte|app.kubernetes.io/instance=airbyte> pods,statefulset,configmap,secret,service    pod "airbyte-minio-0" deleted    statefulset.apps "airbyte-minio" deleted

2. When the new pod is created by the StatefulSet, it will reattach to the existing PVC. This means that the data stored in MinIO will persist across pod deletions. 3. If your goal is to clean up the data stored in MinIO, simply deleting the pod won't achieve this. You would need to delete the PVC as well, but be cautious as this will permanently delete all stored data. 4. Deleting the MinIO pod might cause temporary disruption to Airbyte operations that depend on MinIO for log storage. If you decide to proceed with deleting the pod, you can use a command like this:

kubectl delete pod airbyte-minio-0 -n <your-namespace>

Replace

<your-namespace>

with the actual namespace where Airbyte is deployed. Remember, this action will cause a brief period of unavailability for MinIO storage. The StatefulSet will create a new pod, but there might be a short delay before it's fully operational. Always ensure you have backups of important data before performing operations that could potentially lead to data loss.
