CefSharpDockerfiles | Automated chrome cef building and cefsharp building | Automation library

If you are building in process isolation mode (recommended) make sure the base image file is the same build as your actual OS (or the VM's os). IE if you are on windows Fall 2018 release 1803 (10.0.17134) change VAR_BASE_DOCKER_FILE to the 1803 image. Run ./build.ps1 and it should build the packages. For a super fast start look at the azure auto provision option below. As long as you have an azure account created it can create the entire setup and build in a few commands. If using Azure create a F32_v2 VM with the image "Datacenter Core 1903 with Containers", if using another machine just install docker for windows (make sure you have 20GB (40GB for chrome < 65) of ram between actual ram + page file). Set the Docker For Windows Config File changing the path to the folder to store data on (suggested local temp drive) and restart docker service. Copy the items from this repo into a folder. Copy the versions_src.ps1 to versions.ps1 and change the variables to what you want: for example $VAR_GN_DEFINES="is_official_build=true proprietary_codecs=true ffmpeg_branding=Chrome";$VAR_DUAL_BUILD="1";. Only use DUAL_BUILD if you have 30 gigs of ram or more, otherwise leave it at 0 and the build will take an extra 20-40 minutes.
There is not much in terms of a software requirements other than docker. You can run it on Windows Server or Windows 10 Client. For Windows 10 Client Install it from https://store.docker.com/editions/community/docker-ce-desktop-windows. For server Docker EE from: https://docs.docker.com/install/windows/docker-ee/#docker-universal-control-plane-and-windows (or standard docker for windows for desktops) if docker is not auto installed. If installing on Windows 10 Client make sure to see the Hyper V Notes below.
Once docker is setup and running copy this repo to a local folder. Copy versions_src.ps1 to versions.ps1 and change the version strings to match what you want. NOTE BASE_DOCKER_FILE must match the same kernel as the host machine IF you are using process isolation mode. This means you cannot use the 1709 image on an older host and you can use and older image on a 1709 host. Either base file is fine however to use just match it to the host. Next run build.ps1 and if you are lucky you will end up with a cefsharp_packages.zip file with all the nupkg files you need:) Beware that as docker might be flaky(especially in hyperV mode) you may need to call build.ps1 a few times. It should largely just resume. Once it is done building you will have the cefsharp_packages.zip file. If you want any of the CEF binaries, or symbol files, you can copy them from the CEF image like: docker cp cef:c:/code/binaries/*.zip .
Note the DUAL_BUILD may speed up builds by running x86 and x64 builds concurrently (each with 1/2 as many threads). This is primarily useful during linking. Linking is largely single threaded and takes awhile and is single thread CPU bound (given enough IO). The main issue is memory usage. If both linking steps run at once you may need nearly 30GB of memory at once (in worst case older builds would use up to 50GB). It would be better if they linked at slightly separate times but as every compute system was different there did not seem to be a good way to determine how long to sleep for to make it most efficient.
