Self-Hosted Runner Permission Fixes and Stability Improvements

What's Changed

• Added runAsHostUser to allow running the container as the same user as the host system. This fixes most permissions issues on self-hosted runners. Should be set to true on self-hosted runners so the docker container won't run as root
• Generates a new uuid for machineID to ensure separate containers are unique to reduce license activation errors
• Added exponential delay retry strategy for Ubuntu license activations. Should reduce failed builds due to license activation errors.

Hotfix: Self Hosted Linux Runner Permission Error

Fix permission denied error on Linux self-hosted runners

Windows Improvements and QOL Additions

This release bumps docker images for Windows to Server 2022 in anticipation of Server 2019 EOL. It is highly recommended for users to upgrade to this version as it contains a security fix for personal license serial masking as well as major stability and QOL fixes and improvements.

What's Changed

• [Breaking] Windows images upgraded to Server 2022. This means you must update your workflows to use windows-2022 or ensure self-hosted runners are running Windows Server 2022 or Windows 11 or the images will fail to start
• [Breaking] Updated license activation method to fix increased license activation failures. Personal license activation on Linux now requires UNITY_EMAIL and UNITY_PASSWORD to be passed in addition to UNITY_LICENSE. Look at our License Activation Docs for more guidance.
• Fix serial number leak for personal license activation. This only affects users who only provide a license file for personal activation. Professional serials are not affected. Furthermore, serial numbers require username and password to activate so the risk of malicious use is low. Regardless it is highly recommended to update to v4 to ensure proper masking and for extra security, delete any unexpired build logs.
• Windows now properly uses exit codes for determining build failures. This should bring it in line with Ubuntu behavior and fix several issues introduced by v3. Parsing for error count is now disabled
• Fixes for Windows builds hanging on exit
• Add annotations to default build script so Unity warnings and errors become github annotations to make debugging builds easier. For custom build methods, you can add this CompileListener script to your editor folder to gain the same functionality
• Add containerRegistryRepository and containerRegistryImageVersion fields to allow easier use of custom images and the ability to roll back image versions
• Add dockerCpuLimit, dockerMemoryLimit, and dockerIsolationMode for improved container performance control. Windows containers will by default now use more available system resources to improve build performance. Previously they were stuck at 1 cpu and 1GB memory due to a docker bug
• Building on MacOS no longer requires sudo as long as the license activation path /Library/Application Support/Unity exists
• MacOS setup now installs the correct architecture of Unity to account for Apple Silicon runners by @dcvz in #591
• manualExit suppresses -quit, useful for buildMethods with async calls by @tobyspark in #574
• fix android sdkmanager invocation by @eronnen in #582

New Contributors

• @tobyspark made their first contribution in #574
• @dcvz made their first contribution in #591
