Ignition configurations for Fedora CoreOS
- These are the configs I personally use on my systems. You MUST edit the files before you use them. At the very least, you should add your SSH keys or password hash.
- Only ED25519 SSH keys are accepted with the SSHD hardening configuration. If you do not use ED25519 keys, you will need to adjust the
/etc/ssh/sshd_config.d/10-custom.conffile accordingly. - If you create a passwordless user that requires administrative privileges, ensure that it is part of the
sudogroup (CoreOS allows this group to use sudo without a password) as the configs will disable empty password system authentication. - These configurations are made with a VPS in mind. You should adapt it for a bare metal deployment if that is what you are using (adding additional kernel parameters, configuring drive encryption, configuring storage, etc). You should also change the tuned profile from
virtual-guestappropriately. - The docker-compose-updater.service in
/etc/systemd/systemcan be enabled to have automatic updates for your containers created by Docker Compose. Please make sure that theWorkingDirectoryis appropriate.
I am aware of a dependency issue which may cause the system to not automatically update itself to FCOS 40. To fix the problem, run:
systemctl stop zincati
rpm-ostree override reset clevis tpm2-tools tpm2-tss-fapi
rpm-ostree upgrade
rpm-ostree override remove clevis tpm2-tools tpm2-tss-fapi clevis-pin-tpm2
reboot
