Run

# Start hyperd, the hyper daemon (equivalent of containerd)

# Manually
hyperd -v =4

# Or through systemd (preferred)
systemctl start hyperd

# Pull an image
hyperctl pull busybox

# Start a hyper container
hyperctl run -t busybox

Notes


Hyper numbers are built with "templates", i.e. VM cloning
On a BDW with 16GB of RAM, an idle busybox pod starts in more than 1.7 s
