GitHub has introduced self-hosted runners in beta for its Actions CI/CD platform, offering users more flexibility and control over their workflow environments. These runners allow users to employ their own hardware and software configurations, accommodating specific needs such as proprietary tools or different operating systems and architectures like ARM-based CPUs. They provide enhanced security and networking options, making it easier to connect with on-premises resources. Self-hosted runners also support large workloads by enabling persistent configurations and overcoming the six-hour time-out limitation of hosted virtual environments. Users can configure and manage their self-hosted runners through the Actions tab in their repository settings, using labels to specify the environment setup. Although custom labels are not currently supported, GitHub plans to introduce this feature in future updates, aiming to enhance user experience and meet diverse CI/CD requirements.
