On container startup, the presence of the keypair is checked (`/data/id_ed25519.pub` and `/data/id_ed25519`) and if one of these keys doesn't exist, it's recreated from ENV variables or docker secrets. +Then the validity of the keypair is checked: if public and private keys doesn't match, the container will stop. +If you provide no keys, `hbbs` will generate one for you, and it'll place it in the default location. #### Use ENV to store the key pair diff --git a/docker/rootfs/etc/s6-overlay/s6-rc.d/key-secret/up.real b/docker/rootfs/etc/s6-overlay/s6-rc.d/key-secret/up.real index 90a13dc..e93ac95 100755 --- a/docker/rootfs/etc/s6-overlay/s6-rc.d/key-secret/up.real +++ b/docker/rootfs/etc/s6-overlay/s6-rc.d/key-secret/up.real @@ -26,10 +26,33 @@ if [ ! -f /data/id_ed25519 ] && [ !
