Running multiple builds on a single host for mobile application development is a common practice, but it introduces security and efficiency concerns. This article is about the importance of isolation techniques in mitigating these risks effectively.
Definitions:
By leveraging strategies such as containerization and virtual machine (VM) deployment, developers can ensure that each runner operates independently, minimizing conflicts such as managing different Xcode versions, test cases (simulators and emulators), and library dependencies, thus optimizing performance.
Runners are the machines that execute jobs in a CI/CD workflow. For example, a runner can clone your repository locally, install testing software, and then run commands that evaluate your code. Additionally, insights from best practices in managing multiple runners from other development platforms are integrated to provide comprehensive guidance for creating secure and efficient development environments for mobile applications.
Isolation Techniques: Best Practice
To accommodate multiple builds on a single host, developers often deploy replicas of runners with unique names. This approach enables the execution of numerous runners and jobs on a single host. However, to prevent conflicts and ensure smooth operation, it’s imperative to establish sufficient isolation between these runners.
