SFTP

SFTP

Generate public and private keys for the host (use no passphrase):

mkdir -p keys/{host,user}
ssh-keygen -t ed25519 -f keys/host/ssh_host_ed25519_key < /dev/null
ssh-keygen -t rsa -b 4096 -f keys/host/ssh_host_rsa_key < /dev/null

Add an sftp service to compose.yaml:

sftp:
  image: atmoz/sftp
  command: user:pass:1001
  volumes:
    - ./keys/host/ssh_host_ed25519_key:/etc/ssh/ssh_host_ed25519_key
    - ./keys/host/ssh_host_rsa_key:/etc/ssh/ssh_host_rsa_key
    - ./keys/user:/home/user/.ssh/keys
    - sftp_data:/home/user/upload

Add to the caddy/Caddyfile:
