unikraft instances

unikraft instances copy

Copy a single file to or from an instance which has the sandbox plugin loaded.

A path on an instance is written as <instance>:<path>, optionally prefixed with a metro as <metro>/<instance>:<path>. Exactly one of the two paths may name an instance.

Copying to an instance always overwrites the remote file. Copying from one writes a regular local file, without the permissions it had on the instance.

Code
unikraft instances copy <source> <destination> [flags]

Examples

Copy a local file to an instance:

Code
unikraft instance copy ./config.json my-instance:/etc/app.json

Copy a file off an instance:

Code
unikraft instance copy my-instance:/var/log/app.log ./app.log

Copy a file into a directory, keeping its name:

Code
unikraft instance copy my-instance:/var/log/app.log ./logs/

Copy a file to an instance in a specific metro:

Code
unikraft instance copy ./data.bin fra/my-instance:/var/lib/app.bin
