Importing images

Images of Flatcar Container Linux alpha releases are hosted at https://alpha.release.flatcar-linux.net/amd64-usr/ . There are directories for releases by version as well as current with a copy of the latest version. Similarly, beta releases can be found at https://beta.release.flatcar-linux.net/amd64-usr/ , and stable releases at https://stable.release.flatcar-linux.net/amd64-usr/ .

Each directory has a version.txt file containing version information for the files in that directory. If you are importing images for use inside your environment it is recommended that you fetch version.txt from the current directory and use its contents to compute the path to the other artifacts. For example, to download the alpha OpenStack version of Flatcar Container Linux:
