Hubs Community Edition Services Removal And Migration Discussion
This article delves into the critical discussion surrounding the removal and migration of services within the Hubs Community Edition. The primary goal is to streamline the architecture, address outdated components, and ensure a more maintainable and efficient system. This involves a detailed examination of the current state of services, discrepancies between the community edition and full repositories, and a proposed plan for migration and updates. Let's explore the challenges, solutions, and steps necessary to achieve a robust and up-to-date Hubs Community Edition.
Preamble: The Need for Service Migration
Initially, the services and their configurations required to run Hubs Community Edition were duplicated into the community-edition/services folder within the repository. This was done to guarantee a functional setup of Hubs Community Edition. However, this approach has led to several issues over time. Many of these services have become outdated, and others are likely to follow suit. Moreover, some essential services lack dedicated repositories to track changes or facilitate non-Community Edition setups. To address these challenges, a comprehensive migration strategy is necessary.
The proposal involves removing the services from the community-edition/services folder and replacing them with references to their full repositories. This can be achieved through Git submodules or a script similar to Hubs Compose, which clones the repositories. This ensures that the Community Edition benefits from the latest updates and improvements made to the individual services. However, the migration isn't as straightforward as it seems due to discrepancies between the services in community-edition/services and their counterparts in the full repositories. Some additions and modifications were made specifically for the Community Edition, which now need careful handling.
I have conducted a thorough comparison of the services in community-edition/services with their corresponding full repositories at the time of the copy. This analysis has identified the differences introduced over time. The following sections detail the proposed plan for each service, the discrepancies found, and other relevant notes to guide the migration process.
The (Proposed) Plan: A Detailed Roadmap
1. certbotbot (Transfer/Create)
The certbotbot service currently lacks a full repository. To ensure proper management and version control, this service should be transferred to a dedicated repository. The creation of this repository is a crucial first step in the migration process. A dedicated repository allows for focused development, issue tracking, and streamlined updates, aligning with best practices for service management. This move will also facilitate better integration with other services and components within the Hubs ecosystem.
Creating a full repository for certbotbot involves several key steps. First, the existing code and configurations need to be organized and structured in a way that is conducive to version control and collaboration. This includes setting up a clear directory structure, adding necessary documentation, and configuring build and deployment processes. Additionally, the repository should be initialized with a proper .gitignore file to exclude unnecessary files and directories. Once the repository is set up, it can serve as the central location for all future development and maintenance activities related to certbotbot. This will ensure that the service remains up-to-date, secure, and compatible with the broader Hubs ecosystem. The new repository will also make it easier to track changes, revert to previous versions if necessary, and collaborate with other developers. This is a fundamental step in modernizing the service architecture and ensuring long-term maintainability.
2. coturn (Transfer/Create)
The coturn configuration within community-edition/services is specifically designed for creating Docker images and running coturn in a Community Edition instance. Currently, it lacks its own dedicated repository, although there's a fork of the coturn source code with custom branches, one of which was merged into the upstream coturn. To address this, the coturn configuration should be transferred to a full repository, likely named coturn-ce-config to prevent confusion with the upstream coturn repository.
Creating a dedicated repository for coturn-ce-config will allow for better management of the Community Edition-specific configurations and Docker images. This ensures that any changes or updates to the coturn configuration are tracked and versioned separately from the main coturn codebase. The repository should include the necessary Dockerfiles, configuration files, and scripts required to build and run coturn in the Community Edition environment. This separation of concerns is crucial for maintaining a clean and organized codebase. Furthermore, a dedicated repository facilitates collaboration and allows developers to contribute improvements or fixes specific to the Community Edition deployment of coturn. It also simplifies the process of testing and deploying updates, ensuring that the Community Edition remains compatible with the latest coturn features and security patches.
However, there have been reports that the current coturn configuration might not be functioning correctly. This could be due to the last Mozilla Docker image using the May 24th 2022 release of coturn (4.5.2-r12). It's possible that the Dockerfile needs an update to reference the older, known-stable coturn image. Investigating and resolving this issue is a priority to ensure that the migrated coturn service functions as expected. The Dockerfile should be reviewed to verify the coturn version and update it if necessary. Additionally, testing the updated Docker image in a Community Edition environment is crucial to confirm its functionality before fully migrating the service. This proactive approach will help prevent potential disruptions and ensure a smooth transition.
3. dialog (Remove/Update)
The dialog service in community-edition/services includes netcat fixes that are not present in the main repository. These fixes address a dependency issue for the health check, which prevented the Docker image from being built due to the absence of netcat in newer environments. The solution involved removing netcat and the associated health check, but this change was only applied to the Community Edition version.
Before removing the dialog service from community-edition/services, it's essential to port these netcat fixes to the main repository. This ensures that the improvements are incorporated into the standard dialog codebase, benefiting all users, not just those running the Community Edition. The fixes should be carefully reviewed and tested to ensure they don't introduce any regressions or compatibility issues. If a better fix can be found, it should be implemented instead of simply porting the existing changes. Once the fixes are merged into the main repository, the dialog service can be safely removed from community-edition/services.
The specific fixes include commenting out the health check in scripts/docker/run.sh (lines 4-9) and replacing line 15 in the Dockerfile to remove the netcat installation. The original line # run apt-get update > /dev/null && apt-get install -y jq curl dnsutils netcat > /dev/null was replaced with run apt-get update > /dev/null && apt-get install -y jq curl dnsutils > /dev/null. These changes should be replicated in the main repository, or a more robust solution should be devised. The goal is to ensure that the dialog service builds and runs correctly in all environments, without relying on deprecated dependencies or problematic health checks. By addressing this issue comprehensively, we can maintain a stable and reliable dialog service for the entire Hubs ecosystem.
4. haproxy (Remove/Update)
The haproxy service in community-edition/services essentially builds a Docker image of HAProxy at a specific version. A more efficient approach would be to leverage the official HAProxy Docker image at that version as an override in the community-edition/input-values.yaml file within this repository. This eliminates the need to maintain a separate Dockerfile for HAProxy, simplifying the build and deployment process.
By using the official HAProxy Docker image, we can ensure that we're benefiting from the latest security patches and performance improvements provided by the HAProxy maintainers. It also reduces the maintenance burden on the Hubs team, as we no longer need to track and update the HAProxy Dockerfile ourselves. The specific HAProxy version being used is haproxytech/kubernetes-ingress:1.8.5@sha256:09b59bc272e3aec5ca5b706774ed788c4bb4f184bb1d7ab99660a2b7773b0668. This version should be confirmed to work with the latest edition of Hubs before updating the community-edition/input-values.yaml file.
Updating community-edition/input-values.yaml involves adding an override that specifies the official HAProxy Docker image to use. This ensures that the Community Edition deployment uses the correct version of HAProxy without having to build a custom image. Before making this change, thorough testing is necessary to ensure compatibility with the existing Hubs setup. This includes verifying that HAProxy functions correctly as a load balancer and reverse proxy for the Hubs services. If any issues are encountered, they should be addressed before deploying the change to a production environment. This approach provides a more streamlined and maintainable solution for managing HAProxy in the Community Edition.
5. hubs (Remove/Update)
The hubs service in community-edition/services appears to be mostly identical to the full repository version, with a couple of notable exceptions. The Dockerfile has been renamed, and a changelog.sh script has been added. However, the changelog.sh script currently only functions in the full repository and requires some fixes, such as removing the exit command on line 14.
The primary goal is to align the hubs service in community-edition/services with the full repository version. This involves addressing the Dockerfile renaming and ensuring the changelog.sh script works correctly in both environments. The Dockerfile in the full repository should be renamed to the standard Dockerfile to ensure consistency and compatibility with the community-edition/services/dockerbuildall.sh script. This, however, will require updates to our GitHub Actions as well to ensure that the build process functions correctly.
To achieve this, the Dockerfile in the full repository should be renamed to Dockerfile, and the dockerbuildall.sh script should be updated to reflect this change. Additionally, the GitHub Actions configuration should be modified to use the standard Dockerfile name. This ensures that the build process remains consistent across all environments. The changelog.sh script should also be fixed to function correctly in both the Community Edition and full repository environments. This involves removing the unnecessary exit command and ensuring that the script has the necessary permissions and dependencies. Once these changes are made and tested, the hubs service in community-edition/services can be removed, and the full repository version can be used instead. This streamlines the maintenance process and ensures that the Community Edition benefits from the latest updates and improvements.
6. nearspark (Remove/Update)
The nearspark service in community-edition/services is largely similar to the full repository version. However, there are a few minor differences. In the full repository, the app.js file is guarded with a try/catch block and lacks some commented-out code, while the package.json file was renamed from package.turkey.json. The recommended approach is to generally favor the version in the full repository, with a few considerations.
The try/catch block in the full repository's app.js provides a level of error handling that is beneficial for the stability of the service. It's advisable to keep this version of app.js as it is. The commented-out code is likely not essential and can be safely disregarded. For the package.json file, it's generally better to use the full repository's package.json as the standard. However, it's worth reviewing the dependencies in package.turkey.json and merging any updated dependencies into the full repository's package.json. This ensures that the nearspark service benefits from the latest dependency updates and security patches.
Once these considerations have been addressed, the nearspark service in community-edition/services can be removed. The full repository version, with its improved error handling and potentially updated dependencies, will provide a more robust and maintainable solution. This approach minimizes divergence between the Community Edition and full repository versions, simplifying future updates and maintenance efforts.
7. pgbouncer (Transfer/Create)
The pgbouncer service currently lacks a dedicated repository. To ensure proper management and version control, this service should be transferred to a full repository. A suitable name for this repository could be pgbouncer-ce-config to avoid confusion with the main pgbouncer project. Creating a dedicated repository for pgbouncer-ce-config is essential for managing the Community Edition-specific configurations and Docker images associated with pgbouncer.
This repository will serve as the central location for all files and scripts required to build and run pgbouncer in the Community Edition environment. This includes configuration files, Dockerfiles, and any custom scripts or patches. By having a dedicated repository, we can ensure that changes to the pgbouncer configuration are tracked and versioned separately from the main pgbouncer codebase. This simplifies the process of updating and maintaining the service, as well as collaborating with other developers. The repository should be structured in a way that is clear and easy to navigate, with proper documentation to guide users on how to build and deploy pgbouncer in the Community Edition. This will help ensure that the service remains stable and reliable, and that any issues can be quickly identified and resolved.
8. photomnemonic (Remove)
The photomnemonic service in community-edition/services is identical to its counterpart in the full repository. Therefore, it can be safely removed from community-edition/services. This simplifies the Community Edition codebase and reduces redundancy, as the full repository version is the authoritative source for this service. Removing the duplicate service eliminates the need to maintain two copies of the same code, streamlining updates and reducing the risk of inconsistencies.
This step is part of the broader effort to consolidate services and ensure that the Community Edition relies on the full repositories as much as possible. By removing redundant services, we can make the Community Edition easier to understand, maintain, and update. This also ensures that any improvements or bug fixes made to the photomnemonic service in the full repository are automatically reflected in the Community Edition. This approach promotes a more efficient and consistent development workflow.

The postgres service in community-edition/services is primarily used to build a Docker image of Postgres version 12. A more efficient approach would be to use the official Postgres version 12 Docker image directly, as an override in the community-edition/input-values.yaml file. This eliminates the need to maintain a custom Dockerfile for Postgres and ensures that we're using a well-maintained and secure image.
By leveraging the official Postgres Docker image, we can benefit from the expertise of the Postgres community and ensure that our deployment is aligned with best practices. The official image is regularly updated with security patches and performance improvements, providing a more robust and reliable solution. To implement this change, the community-edition/input-values.yaml file should be updated to specify the official Postgres version 12 Docker image. This will override the default image and ensure that the Community Edition deployment uses the correct version of Postgres.
Before making this change, it's crucial to confirm that Postgres version 12 is compatible with the latest edition of Hubs. Thorough testing should be conducted to verify that all Hubs features that rely on Postgres function correctly. If any compatibility issues are identified, they should be addressed before deploying the change to a production environment. This proactive approach will help prevent disruptions and ensure a smooth transition to using the official Postgres Docker image. This streamlined approach simplifies the maintenance of the Postgres service and ensures that the Community Edition benefits from the latest updates and security patches.
10. postgrest (Remove/Update)
The postgrest service in community-edition/services focuses on building a Docker image of PostgREST version 9.0.1. A more streamlined approach is to utilize the official PostgREST v9.0.1 Docker image directly, as an override in the community-edition/input-values.yaml file. This eliminates the need for a custom Dockerfile and leverages the official, well-maintained image.
Using the official PostgREST Docker image ensures that we benefit from the security updates and performance enhancements provided by the PostgREST maintainers. It also reduces the maintenance overhead for the Hubs team, as we no longer need to manage a separate Dockerfile.
