Solving the Unrecognized SSL message, plaintext connection Error in Spring Vault Tests

If you're working with Spring and integrating HashiCorp Vault, you may come across an error that says, "Unrecognized SSL message, plaintext connection." This can be particularly frustrating, especially when you're trying to set up your Vault container for testing. In this guide, we'll explore the cause of this error and provide a straightforward solution to resolve it.

Understanding the Problem

When you try to perform operations using the Vault template, you might receive an I/O error that states:

[[See Video to Reveal this Text or Code Snippet]]

This error occurs because your application is attempting to connect to the Vault server using HTTPS, but the Vault container is not configured to handle SSL connections properly in a test environment. By default, the VaultTemplate class will use HTTPS if it detects that the service is running on port 8200, but if your container is not serving content over SSL, this will lead to the SSLException.

Step-by-Step Solution

To fix the issue, we need to ensure that the connection to the Vault service is made over HTTP instead of HTTPS. Here’s how to do it:

Updating the VaultTemplate Configuration

Modify the VaultEndpoint Bean: We need to set the scheme of the VaultEndpoint to use HTTP instead of the default HTTPS.

Here is the updated code snippet for your TestsConfiguration class:

Explanation of the Changes

Changing Scheme to HTTP: The key modification made to the code is the line vaultEndpoint.setScheme("http");. This tells your Spring application to connect to the Vault service using an unsecured HTTP connection instead of HTTPS.

Vault Container Configuration: Make sure that the Vault container is correctly set up and started before you use it. The configuration includes defining a token and exposing the relevant port.

Conclusion

By following these steps to set the Vault connection to HTTP, you should be able to eliminate the "Unrecognized SSL message, plaintext connection" error and proceed with your tests involving HashiCorp Vault. Testing with containers can sometimes present unexpected challenges, but adjustments like these can help smooth the process.
