# [Soteria]
|
|
|
|
Soteria: https://en.wikipedia.org/wiki/Soteria_(mythology)
|
|
|
|
> 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 / **rest-server**](https://github.com/restic/rest-server)
|
|
|
|
[REST backend](https://restic.readthedocs.io/en/latest/100_references.html#rest-backend)
|
|
|
|
## Certificates
|
|
|
|
[Certificate Renewal](https://smallstep.com/docs/step-ca/renewal/)
|
|
|
|
Generate a new private key and (public) certificate
|
|
|
|
```
|
|
step ca certificate soteria.john-stream.com certs/foo.crt certs/foo.key --provisioner admin
|
|
```
|
|
|
|
One-time setup for Caddy to be able to trust the Janus CA. This creates a symlink for the root CA.
|
|
|
|
```
|
|
ln -s $(step path)/certs/root_ca.crt certs/root_ca.crt
|
|
```
|
|
|
|
Check certificate
|
|
```
|
|
openssl x509 -in certs/foo.crt -noout -subject -issuer -ext extendedKeyUsage
|
|
```
|
|
|
|
```
|
|
cat certs/foo.crt certs/foo.key > $(step path)/certs/soteria.pem
|
|
```
|
|
|
|
Add to ~/.bashrc to trust the Janus CA:
|
|
|
|
```
|
|
export RESTIC_CACERT=$(step path)/certs/root_ca.crt
|
|
```
|
|
|
|
Create a test repo through the rest server:
|
|
|
|
```
|
|
restic -r rest:https://soteria.john-stream.com:8443/dev-test --tls-client-cert certs/client_combined.pem init
|
|
```
|
|
|
|
## Restic Repos
|
|
|
|
Mounted using a bind mount point in the LXC.
|
|
|
|
https://pve.proxmox.com/wiki/Linux_Container#_bind_mount_points
|
|
|
|
```
|
|
pct set 103 -mp0 /mnt/nfs/restic,mp=/mnt/restic
|
|
```
|
|
|
|
## Restic Clients
|
|
|
|
Set up provisioner password by running this and pasting in the current JWK provisioner password for `admin`
|
|
|
|
```
|
|
read -s secret && (umask 077; echo "$secret" > secret.txt)
|
|
```
|
|
|
|
```
|
|
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
|
|
```
|
|
|
|
