feat(node/docker): Allow the Use of a Local Version of the Codebase to Build the Node's Image

Description

As of May 19th, 2025, we are limited to passing a remote tag/commit-hash to build docker images for the kona-node. This approach can be cumbersome, especially when working with local versions of the codebase. It would be highly beneficial to be able to build docker images of the node from local versions of it, providing more flexibility and convenience in the development process.

Benefits of Using a Local Version

Using a local version of the codebase to build the node's image offers several advantages. Firstly, it eliminates the need to rely on remote tags or commit hashes, which can be prone to errors or inconsistencies. By using a local version, developers can ensure that the image is built from a consistent and up-to-date codebase, reducing the risk of errors or inconsistencies.

Secondly, using a local version allows developers to work with the latest changes and updates without having to wait for a remote build to complete. This can significantly speed up the development process, enabling developers to test and iterate on their changes more quickly.

Lastly, using a local version provides more control over the build process, allowing developers to customize and fine-tune the image to meet their specific needs. This can be particularly useful in environments where customizations or modifications are required.

Course of Action

To enable the use of a local version of the codebase to build the node's image, we would need to update the docker-bake.hcl file to add a parameter that enables this functionality. This parameter would allow developers to specify whether to use a local version of the kona-node to generate a docker image.

Here is an example of how this parameter could be implemented:

parameter "use_local_image" {
  type        = bool
  description = "Whether to use a local version of the kona-node to generate a docker image"
  default     = false
}

With this parameter in place, developers can specify whether to use a local version of the codebase to build the node's image. If set to true, the docker-bake tool would use the local version of the kona-node to generate a docker image.

Implementation Details

To implement this feature, we would need to make the following changes to the docker-bake tool:

  1. Add a new parameter to the docker-bake.hcl file to enable the use of a local version of the codebase.
  2. Update the docker-bake tool to use the local version of the kona-node when the use_local_image parameter is set to true.
  3. Test the updated docker-bake tool to ensure that it works correctly with both local and remote versions of the codebase.

Example Use Case

Here is an example of how a developer might use the docker-bake tool with the use_local_image parameter:

docker-bake -use_local_image=true

In this example, the docker-bake tool would use the local version of the kona-node to generate a docker image.

Conclusion

Enabling the use of a local version of the codebase to build the node's image would provide significant benefits to, including increased flexibility, speed, and control over the build process. By updating the docker-bake.hcl file to add a parameter that enables this functionality, we can make it easier for developers to work with local versions of the codebase and improve the overall development experience.

Future Work

In the future, we may want to consider adding additional features to the docker-bake tool, such as:

  • Support for multiple local versions of the codebase
  • Ability to specify a specific branch or commit hash for the local version
  • Integration with other tools and services to automate the build process

By continuing to improve and expand the docker-bake tool, we can make it an even more powerful and flexible tool for developers working with the kona-node.
Q&A: feat(node/docker): Allow the Use of a Local Version of the Codebase to Build the Node's Image

Frequently Asked Questions

We've received several questions about the proposed feature to allow the use of a local version of the codebase to build the node's image. Below, we've answered some of the most common questions to help clarify the feature and its benefits.

Q: What is the current limitation with building docker images for the kona-node?

A: Currently, we can only pass a remote tag/commit-hash to build docker images for the kona-node. This can be cumbersome, especially when working with local versions of the codebase.

Q: How does using a local version of the codebase to build the node's image improve the development process?

A: Using a local version of the codebase to build the node's image provides several benefits, including increased flexibility, speed, and control over the build process. It eliminates the need to rely on remote tags or commit hashes, which can be prone to errors or inconsistencies.

Q: How would the use_local_image parameter work?

A: The use_local_image parameter would be added to the docker-bake.hcl file to enable the use of a local version of the codebase to build the node's image. When set to true, the docker-bake tool would use the local version of the kona-node to generate a docker image.

Q: What are the potential risks or challenges associated with using a local version of the codebase to build the node's image?

A: While using a local version of the codebase to build the node's image provides several benefits, there are also potential risks or challenges to consider. For example, using a local version may introduce inconsistencies or errors if the local version is not up-to-date or is not properly configured.

Q: How would the docker-bake tool be updated to support the use of a local version of the codebase?

A: To support the use of a local version of the codebase, the docker-bake tool would need to be updated to use the local version of the kona-node when the use_local_image parameter is set to true. This would involve making changes to the docker-bake.hcl file and testing the updated tool to ensure that it works correctly with both local and remote versions of the codebase.

Q: What are the potential benefits of using a local version of the codebase to build the node's image in terms of security?

A: Using a local version of the codebase to build the node's image can provide several security benefits, including reduced exposure to remote vulnerabilities and improved control over the build process. By using a local version, developers can ensure that the image is built from a consistent and up-to-date codebase, reducing the risk of errors or inconsistencies.

Q: How would the use_local_image parameter be used in practice?

A: The use_local_image parameter would be used in practice by specifying it as a flag when running the docker-bake tool. For example:

docker-bake -use_local_image=true

In this example, the docker-bake tool would use the local version of the kona-node to generate a image.

Conclusion

Using a local version of the codebase to build the node's image provides several benefits, including increased flexibility, speed, and control over the build process. By updating the docker-bake.hcl file to add a parameter that enables this functionality, we can make it easier for developers to work with local versions of the codebase and improve the overall development experience.
