Managing multiple static websites often requires balancing operational simplicity with the need to prevent one project from impacting another. At E Tech Code, we encountered this challenge firsthand and decided to migrate from a shared hosting environment to a containerized infrastructure. This article details the technical decisions, deployment strategies, and maintenance practices that enabled us to achieve isolated, reliable deployments for five static sites—without introducing unnecessary complexity.
Recognizing the Drawbacks of Shared Hosting
Our initial setup placed all five static sites on a shared hosting platform. While this approach was affordable and easy to manage, it quickly revealed several limitations as our projects evolved. Shared hosting environments typically run multiple sites on the same server, using a common software stack and shared resources. This meant that a configuration change, software update, or even a minor error in one site could inadvertently affect the others.
Additionally, deployment processes were tightly coupled. A single deployment script or update could cause downtime or errors across multiple sites, making it difficult to iterate safely. This lack of isolation became a growing concern as the importance and complexity of each project increased.
Moving to Docker Containers for Project Isolation
To address these issues, we decided to migrate each static site into its own Docker container, all hosted on a single Virtual Private Server (VPS). This move was motivated by the need for clear separation between projects at the infrastructure level. By encapsulating each site and its dependencies within its own container, we ensured that changes or failures in one project would not impact the others.
Docker’s lightweight virtualization allowed us to run all five sites independently on the same VPS, without the overhead of managing multiple virtual machines. This setup also made it easier to allocate resources and monitor each site individually, further reducing the risk of cross-project interference.
Adopting Astro for Static Site Generation
We standardized on Astro as the static site generator for all five projects. Astro’s modern build process and efficient architecture made it a natural fit for containerized deployment. Each site’s repository contained its Astro source code, allowing for consistent and reproducible builds within the container environment.
By using Astro, we further decoupled our sites from backend dependencies, aligning with our goal of minimizing cross-project risks. The static nature of the sites reduced runtime complexity and potential points of failure, making deployments more predictable and easier to maintain.
Implementing CI/CD with Commit-Based Deployment Triggers
To streamline deployment and minimize manual errors, we integrated Continuous Integration and Continuous Deployment (CI/CD) pipelines for each repository. A key operational decision was to restrict deployments to commits that explicitly include the tag [deploy] in their commit message.
This approach prevents unintended deployments triggered by routine commits or merges, giving developers precise control over when a site is released. The CI/CD pipeline builds the Astro site inside its Docker container and deploys the updated container to the VPS, replacing the previous version seamlessly.
By automating the build and deployment process while requiring explicit intent to deploy, we reduced the risk of accidental downtime or incomplete updates. This practice also encouraged disciplined commit messaging and operational awareness among team members.
Evaluating Alternatives and Addressing New Challenges
Before settling on containerization, we considered alternatives such as using multiple virtual machines or enhancing deployment protocols within the shared hosting environment. While virtual machines would have provided isolation, they came with higher resource and management costs. Strengthening protocols on shared hosting would not have fully eliminated the risk of cross-site interference.
Containerization introduced its own considerations, such as managing container orchestration and ensuring the VPS had sufficient resources for all sites. However, the benefits in deployment safety and operational independence outweighed these challenges. Early on, we learned the importance of enforcing strict commit message conventions to avoid accidental deployments. Automated checks and clear guidelines were established to support this discipline.
Practical Takeaways for Teams Managing Multiple Static Sites
For teams or small businesses considering a similar migration, containerizing static sites offers a balanced solution between isolation and operational simplicity. Key recommendations based on our experience include:
- Use a static site generator like Astro to simplify builds and reduce runtime dependencies.
- Containerize each site separately to isolate deployments and runtime environments.
- Implement CI/CD pipelines with explicit deployment triggers, such as requiring a [deploy] tag in commit messages, to control releases.
- Select a VPS with adequate resources to support multiple containers efficiently.
- Establish and enforce clear commit message conventions to prevent accidental deployments.
By adopting these practices, organizations can maintain multiple projects on shared infrastructure while minimizing operational risks and overhead. Our experience at E Tech Code demonstrates that thoughtful technical decisions, combined with disciplined operational processes, can significantly improve deployment safety and maintainability for static sites.
