S3 Backup/Restore Fails with Microceph/Rados-GW and TLS: A Troubleshooting Guide

In this article, we will explore the issue of S3 backup/restore failing with Microceph/Rados-GW and TLS. We will walk through the steps to reproduce the issue, the expected behavior, and the actual behavior. Additionally, we will provide a detailed analysis of the error message and offer potential solutions to resolve the issue.

To reproduce the issue, follow these steps:

Step 1: Deploy an Instance of Microceph with Rados-Gateway and TLS Enabled

Deploy an instance of Microceph with Rados-Gateway and TLS enabled. This will create a secure environment for storing and retrieving data.

Step 2: Deploy Opensearch with TLS

Deploy Opensearch with TLS enabled. This will ensure that all communication between Opensearch and the S3 repository is encrypted.

Step 3: Deploy S3-Integrator with the Following Configuration

Deploy S3-integrator with the following configuration:

endpoint="https://[ip-address_of_microceph]:445" \
bucket="[bucket-name]" \
path="[path]" \
tls-ca-chain="$(base64 -w0 your_cert.pem)"

This configuration specifies the endpoint, bucket, path, and TLS CA chain for the S3 repository.

Step 4: Relate S3-Integrator and Opensearch

Relate S3-integrator and Opensearch to enable the backup and restore functionality.

The expected behavior is that Opensearch sets up the S3 repository successfully, allowing for backup and restore operations.

However, the actual behavior is that the setup of the S3 repository fails with the following error:

unit-opensearch-0: 10:45:58 ERROR unit.opensearch/0.juju-log s3-credentials:5: Failed to setup backup service with exception: HTTP error self.response_code=500

The error message indicates that there is a problem with the PKIX path building, which is a process used to validate the identity of a server. The error message specifically mentions that the sun.security.provider.certpath.SunCertPathBuilderException exception is being thrown, which indicates that the Java runtime environment is unable to find a valid certification path to the requested target.

Based on the error analysis, there are several potential solutions to resolve the issue:

Solution 1: Verify the TLS CA Chain

Verify that the TLS CA chain is correctly configured and that the certificate is valid. Make sure that the certificate is not expired and that it is properly signed by a trusted certificate authority.

Solution 2: Update the Java Runtime Environment

Update the Java runtime environment to the latest version, which may include fixes for the PKIX path building issue.

Solution 3: Configure the S3 Repository

Configure the S3 repository to use a different endpoint or bucket, which may resolve the issue.

Solution 4: Disable TLS

Disable TLS and use a different encryption method, such as SSL, to resolve the issue.

In conclusion, the S3 backup/restore fails with Microceph/Rados-GW and TLS due to a PKIX path building issue. The error message indicates that the Java runtime environment is unable to find a valid certification path to the requested target. Potential solutions include verifying the TLS CA chain, updating the Java runtime environment, configuring the S3 repository, and disabling TLS. By following these steps, you should be able to resolve the issue and successfully set up the S3 repository.
S3 Backup/Restore Fails with Microceph/Rados-GW and TLS: A Q&A Guide

In our previous article, we explored the issue of S3 backup/restore failing with Microceph/Rados-GW and TLS. We walked through the steps to reproduce the issue, the expected behavior, and the actual behavior. Additionally, we provided a detailed analysis of the error message and offered potential solutions to resolve the issue.

In this article, we will provide a Q&A guide to help you better understand the issue and its potential solutions. We will answer some of the most frequently asked questions related to S3 backup/restore with Microceph/Rados-GW and TLS.

Q: What is the root cause of the S3 backup/restore failure with Microceph/Rados-GW and TLS?

A: The root cause of the S3 backup/restore failure with Microceph/Rados-GW and TLS is a PKIX path building issue. This issue occurs when the Java runtime environment is unable to find a valid certification path to the requested target.

Q: What is a PKIX path building issue?

A: A PKIX path building issue is a problem that occurs when the Java runtime environment is unable to find a valid certification path to the requested target. This can happen when the certificate is not properly signed by a trusted certificate authority or when the certificate is expired.

Q: How can I verify the TLS CA chain?

A: To verify the TLS CA chain, you can follow these steps:

  1. Check the certificate file to ensure that it is not expired.
  2. Verify that the certificate is properly signed by a trusted certificate authority.
  3. Check the certificate chain to ensure that it is complete and valid.

Q: How can I update the Java runtime environment?

A: To update the Java runtime environment, you can follow these steps:

  1. Check the Java version to ensure that it is up-to-date.
  2. Download the latest version of the Java runtime environment.
  3. Install the latest version of the Java runtime environment.

Q: How can I configure the S3 repository?

A: To configure the S3 repository, you can follow these steps:

  1. Check the S3 repository configuration to ensure that it is correct.
  2. Verify that the S3 repository is properly configured to use the correct endpoint and bucket.
  3. Check the S3 repository logs to ensure that there are no errors.

Q: How can I disable TLS?

A: To disable TLS, you can follow these steps:

  1. Check the application configuration to ensure that TLS is enabled.
  2. Disable TLS in the application configuration.
  3. Verify that the application is working correctly without TLS.

Q: What are the potential risks of disabling TLS?

A: Disabling TLS can pose a significant risk to the security of your application. Without TLS, data transmitted between the client and server is not encrypted, making it vulnerable to interception and eavesdropping.

Q: How can I troubleshoot the S3 backup/restore issue?

A: To troubleshoot the S3 backup/restore issue, you can follow these steps:

  1. Check the S3 repository logs to ensure that there are no errors.
  2. Verify that the S3 repository is properly configured to use the correct endpoint and bucket.
  3. Check the Java environment to ensure that it is up-to-date.

In conclusion, the S3 backup/restore fails with Microceph/Rados-GW and TLS due to a PKIX path building issue. By following the steps outlined in this Q&A guide, you should be able to resolve the issue and successfully set up the S3 repository. Remember to always verify the TLS CA chain, update the Java runtime environment, configure the S3 repository, and disable TLS only if necessary.
