rkt stop
Given a list of pod UUIDs, rkt stop will shut them down, for the shipped stage1 images, this means:
- default systemd-nspawn stage1: the apps in the pod receive a TERM signal and, after a timeout, a KILL signal.
- kvm stage1: the virtual machine is shut down with
systemctl halt
. - rkt fly stage1: the app receives a TERM signal.
The --force
flag will stop a pod forcibly, that is:
- default systemd-nspawn stage1: the container is killed.
- kvm stage1: the qemu or lkvm process receives a KILL signal.
- rkt fly stage1: the app receives a KILL signal.

The --uuid-file
flag may be used to pass a text file with UUID to stop
command.
This can be paired with --uuid-file-save
flag to stop pods by name:
rkt run --uuid-file-save=/run/rkt-uuids/mypod ...
rkt stop --uuid-file=/run/rkt-uuids/mypod
Other ways to stop a rkt pod
If you started rkt as a systemd service, you can stop the pod with systemctl stop
.
If you started rkt interactively:
- For a stage1 with systemd-nspawn, you can stop the pod by pressing
^]
three times within 5 seconds. If you're using systemd on the host, you can also usemachinectl
with thepoweroff
orterminate
subcommand. - For a stage1 with kvm, you can stop the pod by pressing Ctrl+A and then x.
