MySQL Docker allowpublickeyretrieval Error | Troubleshooting

Local development with Golang often involves using Docker containers for various services like MySQL. However, many developers run into errors when connecting Golang applications to MySQL.

Today, we are going to take a look at In this blog post, we’ll explore a common issue and walk through multiple solutions to help you overcome MySQL connection challenges when working with Golang.

Let’s take a look at some of the few common errors:

• Authentication Protocol Mismatch:

  When we use tools like sqltools for vscode, we may run into an authentication protocol error. The error message suggests upgrading the MySQL client to resolve the issue.
• Access Denied for User:

  Running the Golang application leads to an “Access denied” error for the user, even though successful connections are established through other clients.
• Public Key Retrieval Not Allowed:

  DBeaver successfully connects, but attempting the same without changing configurations leads to a “Public Key Retrieval not allowed” error.

Solutions Explored

1. Adjust Driver Settings:

   Head to the driver settings and change the value of “allowPublicKeyRetrieval” from “false” to “true.” This will smoothen function operations.
2. JDBC Query Adjustment

   Our experts recommend including ?allowPublicKeyRetrieval=true before executing the JDBC query.

   We have to verify the method used to initiate the MySQL Docker image and ensure accessible ports. Additionally, use the root account/password given by MySQL during the initial stages. We also need to confirm the existence of the web user.
3. JDBC URL Adjustment

   In this case, modify the JDBC URL to include allowPublicKeyRetrieval=true&useSSL=false.

   For example:

   String url = "jdbc:mysql://192.168.56.101:3306/mysql?allowPublicKeyRetrieval=true&useSSL=false".
4. DBeaver Connection Settings
   • In DBeaver, right-click the connection and choose “Edit Connection.”
   • Then, click “Edit Driver Settings” and head to “Connection properties.”
   • Next, add properties useSSL=false and allowPublicKeyRetrieval=true.
   • Save and retest the connection.
