In Greek mythology, Soteria (Greek: Σωτηρία) was the goddess or spirit (daimon) of safety and salvation, deliverance, and preservation from harm
Intent
Connect solely through wireguard to 192.168.1.142 and serve the REST server with a certificate signed by Janus.
Restic REST Server
Restic Repos
/etc/fstab entry:
john-nas:/volume1/restic /mnt/nfs/restic nfs nofail,_netdev,x-systemd.automount,x-systemd.idle-timeout=600,timeo=14,retrans=3,hard,tcp,nfsvers=3 0 0
Mounted using a bind mount point in the LXC.

pct set 103 -mp0 /mnt/nfs/restic,mp=/mnt/restic
Soteria Certificates
Generate a new private key and (public) certificate in the right places. This will use the admin provisioner.
step ca certificate soteria.john-stream.com certs/soteria.crt certs/soteria.key --provisioner admin
Check the resultant certificate:
openssl x509 -noout -subject -issuer -ext extendedKeyUsage -ext subjectAltName -in certs/soteria.crt
Set up renewal
sudo ./scripts/install_services.sh
Test renewal
systemctl start cert-renewer.service && \
systemctl status cert-renewer.service --no-pager && \
Clients
To set up a client, run the following command. It will prompt for the provisioner password and the repository name.
curl -sL https://gitea.john-stream.com/john/soteria/raw/branch/main/scripts/setup_client.sh | bash
curl -sL https://gitea.john-stream.com/john/soteria/raw/branch/main/scripts/check_status.sh | bash
Manual Setup
Set up provisioner password by running this and pasting in the current JWK provisioner password for admin
read -s secret && (umask 077; echo "$secret" > $(step path)/certs/secret.txt)
Generate the client TLS private key and (public) certificate for mTLS. This will combine them both into a file called restic.pem, which can be used with the --tls-client-cert option with the restic CLI.
cd $(step path)/certs && \
step ca certificate \
--provisioner admin --password-file secret.txt \
$(hostnamectl hostname) restic.crt restic.key && \
(umask 077; cat restic.crt restic.key > restic.pem)
Need restic 0.16+ for the env vars RESTIC_CACERT and RESTIC_TLS_CLIENT_CERT to work.
export RESTIC_CACERT=$(step path)/certs/root_ca.crt
export RESTIC_TLS_CLIENT_CERT=$(step path)/certs/restic.pem
export RESTIC_REPOSITORY=rest:https://soteria.john-stream.com/john-ubuntu
export RESTIC_PASSWORD_FILE=$(readlink -f ~/.config/resticprofile/password.txt)
Create a test repo through the rest server:
