Dockerfile

# To build for multiple different platforms with the same docker image
# you need to rebuild this image with https://github.com/game-ci/docker/releases/tag/v0.15 or newer (with https://github.com/game-ci/docker/pull/116)
# e.g. for 2020.3.19f1 version with linux, windows, android and mac support:
# --build-arg version="2020.3.19f1"
# --build-arg changeSet="68f137dc9bbe"                # you can find changeSet value in release announcement, e.g. https://unity3d.com/unity/whats-new/2020.3.19 has "Unity Hub" link unityhub://2020.3.19f1/68f137dc9bbe
# --build-arg module="windows-mono android mac-mono"  # linux support is already included by default
# use an image with only windows-mono support as an example until the images with multiple modules are available on dockerhub

# install dependencies:
# libvulkan1:
#     - is loaded by Unity during the build
#     - Unity would use llvmpipe renderer when missing as in:
#       [vulkan] LoadVulkanLibrary libvulkan.so.1
#       [vulkan] LoadVulkanLibrary failed to load libvulkan.so.1Vulkan detection: 0)
# mesa-vulkan-drivers:
#     - is needed for libvulkan1 to work
#     - otherwise vulkaninfo fails with:
#       vulkan-tools-1.2.131.1+dfsg1/vulkaninfo/vulkaninfo.h:371: failed with ERROR_INCOMPATIBLE_DRIVER)
# osslsigncode:
#     - is needed by build-simulator.sh script when building for windows:
#       Jenkins/build-simulator.sh:    osslsigncode sign
# uuid-runtime:
#     - needed to generate IMAGE_UUID:
#       Jenkins/Dockerfile:IMAGE_UUID=\"$(uuidgen)\""
# vulkan-tools:
#     - used to be vulkan-utils in 18.04 ubuntu
#     - usefull to test that docker image can initialize vulkan with `vulkaninfo`
#     - but it doesn't work without mesa-vulkan-drivers, so install it only to verify Vulkan
# zip:
#     - is needed by build-simulator.sh script:
#       Jenkins/build-simulator.sh:zip -r /mnt/${BUILD_OUTPUT}.zip ${BUILD_OUTPUT}
