Cua DocumentationPrebuilt Images
Pre-built images are available in the registry ghcr.io/trycua. These images come with an SSH server pre-configured and auto-login enabled.
The default password on pre-built images is lume. For the security of your VM, change this password after your first login.

Disk Space
For additional disk space, resize the VM disk after pulling the image using the lume set <name> --disk-size <size> command. Note that the actual disk space used by sparse images will be much lower than the logical size listed.
Important Note (v0.2.0+): Images are being re-uploaded with sparse file system optimizations enabled, resulting in significantly lower actual disk usage. Older images (without the -sparse suffix) are now deprecated. The last version of lume fully supporting the non-sparse images was v0.1.x. Starting from v0.2.0, lume will automatically pull images optimized with sparse file system support.
