![]() The Linux kernel used by WSL is updated automatically.WSL can run Windows executables from Linux, which could also lead to a different environment than a traditional Linux VM.Windows paths are appended to your path by default, which could cause unexpected behavior for certain Linux applications compared to a traditional Linux environment.WSL automatically gives file access to Windows files.The lifetime of the VM, the registered WSL distributions, etc., are all accessible by the user and can be modified by the user. WSL users have full access to their Linux instances.This means if you are using it as a web server, SSH into it to run your server and then exit, the VM could shut down because it is detecting that users are finished using it and will clean up its resources. If you have no open file handles to Windows processes, the WSL VM will automatically be shut down. ![]() WSL has a lightweight utility VM that starts, stops and manages resources automatically.The main differences between WSL and a traditional production environment are: Our goal is to make clear how WSL differs from a regular VM environment, so you can make the decision on whether it fits your business needs. There are design features in WSL that make it great for this purpose but may make it challenging for production-related scenarios compared to other products. When os is not windows, values are implementation-defined and SHOULD be submitted to this specification for standardization.īeta Was this translation helpful? Give feedback.WSL has been designed and built to use with inner loop development workflows. win32k: image requires win32k.sys on the host (Note: win32k.sys is missing on Nano Server).When os is windows, image indexes SHOULD use, and implementations SHOULD understand the following values: This OPTIONAL property specifies an array of strings, each specifying a mandatory OS feature. Implementations MAY refuse to use manifests where os.version is not known to work with the host OS version. This OPTIONAL property specifies the version of the operating system targeted by the referenced blob. amd64) and variant (mostly for ARM architectures, but some x86 variants may be used. On Linux, all current implementations of OCI runtimes use os (i.e., linux) arch (e.g. These fields are currently only used to match Windows images, where os.version is important to match a compatible kernel version (and to some extend os.features may be used as well). The "os.features" and "os.version" options are a bit of a gray area in the OCI specification. My host1 information for cat /etc/os-release is as follows Note that I am just concerned about Linux systems. Image2 annotation will be os.version Y os.features YY where Y and YY refer to host2 information.īy creating and pushing this manifest, I would like Docker to pull the relevant image to a host upon runningĮ.g., if the host os version and features match X and XX, pull image1. Image1 annotation will be os.version X os.features XX where X and XX refer to host1 information. Where to obtain the correct value for os.version and os.features in Linux? My guess is that they come from cat /etc/os-release and cat /proc/cpuinfo.Īre the annotations strictly checked by Docker when pulling an image of a manifest or they are just informational?Īn example docker manifest in my mind is this: I thought maybe I can annotate each image with different values for os.version and os.features so when pulling the image, the one relevant to the host's os version and features gets pulled. I have to achieve a Docker manifest that contains 2 images for identical (Linux) OS and Arch but for different OS versions and features.
