Images

Images (disk images) are the artifacts produced by OPS. These disk images can be ran on a variety of hypervisors including the top public cloud providers such as AWS and Google Cloud.

All local images are stored locally in ~/.ops/images/ and can be viewed like:

ops image list -t onprem

OPS has several commands that allow one to work on disk images when not running them. This can help provide debugging support.

ls

ops image ls myimage

Provides a 'ls' style listing of files in a local (on-prem) image from rootfs partition.

ops image ls myimage --bootfs

Provides a 'ls' style listing of files in a local (on-prem) image from bootfs partition.

cat

ops image cat g /etc/resolv.conf

Cats the file out of an image.

cp

ops image cp -r redis-server lib .

Recursively copies the output of the folder '/lib' into the host from the image 'redis-server' rootfs partition.

ops image cp redis-server kernel . --bootfs

Copies the 'kernel' into the host from the image 'redis-server' bootfs partition.

ops image cp -r redis-server klib .

Recursively copies the output of the folder '/klib' into the host from the image 'redis-server' bootfs partition.

tree

ops image tree redis-server

Displays the tree output of local (on-prem) image from rootfs partition.

ops image tree redis-server --bootfs

Displays the tree output of local (on-prem) image from bootfs partition.

env

ops image env redis-server

Displays the list of environment variables found in a local (on-prem) image.

mirror

ops image mirror myimage <src_region> <dst_region>
