Docker Hub vs GitHub: What are the differences?
Key Differences between Docker Hub and GitHub
Introduction
In the world of software development and deployment, Docker Hub and GitHub are two popular platforms that serve different purposes. While Docker Hub is focused on hosting and sharing containerized applications, GitHub is primarily used for version control and collaborative software development. This article aims to highlight the key differences between Docker Hub and GitHub.
Storage and Hosting: Docker Hub is primarily a container registry that allows developers to store and share Docker images. It provides a centralized platform for hosting containerized applications and allows easy distribution and deployment of images. On the other hand, GitHub is a code hosting platform that offers version control repositories. It enables developers to store and manage their codebase, collaborate with others, and track changes over time.
Focus: Docker Hub is specifically designed for Docker-based containerization. It provides a platform for developers to store, share, and pull Docker images from a central repository. It includes features like automated builds, image signing, and image tagging. GitHub, on the other hand, caters to a broader range of software development needs. It supports various programming languages and frameworks, offering features like issue tracking, pull requests, code reviews, and project management tools.
Community and Collaboration: Docker Hub fosters a community of Docker users and provides a platform for developers to share their containerized applications with others. It allows users to collaborate on Docker images, making it easier to build upon existing work. GitHub, on the other hand, has a larger focus on collaboration. It offers features like pull requests, code reviews, and commenting, enabling developers to collaborate on codebases, contribute changes, and discuss ideas.
Deployment and Continuous Integration: Docker Hub emphasizes the deployment of containerized applications. It supports automated builds, allowing developers to build and deploy Docker images directly from their code repositories. GitHub, on the other hand, provides integrations with various continuous integration and deployment tools. It allows developers to set up workflows and pipelines to automatically build, test, and deploy their applications.
Licensing and Open Source: GitHub has a strong affiliation with open-source software. It provides a platform for hosting open-source projects and encourages developers to make their code publicly accessible. It offers features like licenses, project templates, and contribution guidelines. Docker Hub, although widely used for open-source projects, does not have the same level of emphasis on promoting open source. It primarily focuses on providing a registry for Docker images, regardless of their open-source or proprietary nature.
Pricing and Cost: Docker Hub offers both free and paid plans. While the free plan allows for basic usage, the paid plans provide additional features like private repositories, increased storage limits, and enhanced support. GitHub offers a similar pricing structure, with free plans for public repositories and paid plans for private repositories. The cost may vary based on factors like storage size, number of collaborators, and additional features.
In Summary, Docker Hub is a container registry platform focused on hosting and sharing Docker images, while GitHub is a code hosting platform for version control and collaborative software development. Docker Hub is specialized in containerization and deployment, while GitHub offers a broader range of development tools and features.
Do you review your Pull/Merge Request before assigning Reviewers?
If you work in a team opening a Pull Request (or Merge Request) looks appropriate. However, have you ever thought about opening a Pull/Merge Request when working by yourself? Here's a checklist of things you can review in your own:
- Pick the correct target branch
- Make Drafts explicit
- Name things properly
- Ask help for tools
- Remove the noise
- Fetch necessary data
- Understand Mergeability
- Pass the message
- Add screenshots
- Be found in the future
- Comment inline in your changes
Read the blog post for more detailed explanation for each item :D
What else do you review before asking for code review?
Using an inclusive language is crucial for fostering a diverse culture. Git has changed the naming conventions to be more language-inclusive, and so you should change. Our development tools, like GitHub and GitLab, already supports the change.
SourceLevel deals very nicely with repositories that changed the master branch to a more appropriate word. Besides, you can use the grep linter the look for exclusive terms contained in the source code.
As the inclusive language gap may happen in other aspects of our lives, have you already thought about them?
One of the magic tricks git performs is the ability to rewrite log history. You can do it in many ways, but git rebase -i is the one I most use. With this command, It’s possible to switch commits order, remove a commit, squash two or more commits, or edit, for instance.
It’s particularly useful to run it before opening a pull request. It allows developers to “clean up” the mess and organize commits before submitting to review. If you follow the practice 3 and 4, then the list of commits should look very similar to a task list. It should reveal the rationale you had, telling the story of how you end up with that final code.
Out of most of the VCS solutions out there, we found Gitlab was the most feature complete with a free community edition. Their DevSecops offering is also a very robust solution. Gitlab CI/CD was quite easy to setup and the direct integration with your VCS + CI/CD is also a bonus. Out of the box integration with major cloud providers, alerting through instant messages etc. are all extremely convenient. We push our CI/CD updates to MS Teams.
Gitlab as A LOT of features that GitHub and Azure DevOps are missing. Even if both GH and Azure are backed by Microsoft, GitLab being open source has a faster upgrade rate and the hosted by gitlab.com solution seems more appealing than anything else! Quick win: the UI is way better and the Pipeline is way easier to setup on GitLab!
At DeployPlace we use self-hosted GitLab, we have chosen GitLab as most of us are familiar with it. We are happy with all features GitLab provides, I can’t imagine our life without integrated GitLab CI. Another important feature for us is integrated code review tool, we use it every day, we use merge requests, code reviews, branching. To be honest, most of us have GitHub accounts as well, we like to contribute in open source, and we want to be a part of the tech community, but lack of solutions from GitHub in the area of CI doesn’t let us chose it for our projects.
