# Fedora CoreOS
|
||
|
|
|
||
|
|
Tested with stable version 31.20200223.3.0
|
||
|
|
Because package installation with `rpm-ostree` requires a reboot, playbook may fail while bootstrap.
|
||
|
|
Restart playbook again.
|
||
|
|
|
||
|
|
## Containers
|
||
|
|
|
||
|
|
Tested with
|
||
|
|
|
||
|
|
- docker
|
||
|
|
- crio
|
||
|
|
|
||
|
|
### docker
|
||
|
|
|
||
|
|
OS base packages contains docker.
|
||
|
|
|
||
|
|
### cri-o
|
||
|
|
|
||
|
|
To use `cri-o` disable docker service with ignition:
|
||
|
|
|
||
|
|
```yaml
|
||
|
|
#workaround, see https://github.com/coreos/fedora-coreos-tracker/issues/229
|
||
|

systemd:
|
||
|
|
units:
|
||
|
|
- name: docker.service
|
||
|
|
enabled: false
