Customize the OS image

It is possible to create docker images that specialize a footloose base image to suit your needs.

For instance, if we want the created machines to run fedora29 with the htop package already pre-installed:

FROM quay.io/footloose/fedora29

# Pre-seed the htop package
RUN dnf -y install htop && dnf clean all

Build that image:

docker build -t fedora29-htop .

Configure footloose.yaml to use that image by either editing the file or running:

footloose config create --image fedora29-htop

htop will be available on the newly created machines!

$ footloose create
$ footloose ssh root@node0
# htop
