GitHub-hosted Runner

GitHub-hosted runners are virtual machines operated by GitHub Inc. that are used to execute workflows. They are available exclusively for GitHub Enterprise Cloud (GHEC). For GitHub Enterprise Server (GHES), the Self-hosted Runners must be used.

Characteristics

• Each job receives a fresh, isolated virtual machine.
• The environment is automatically discarded after the job completes.
• Common development tools are pre-installed (e.g., Node.js, Python, Java, Docker).
• Internet connectivity is available by default.
• No access to the local network of the University of Bern.
