Docker secrets

💁 Note this is a bit pointless, since gluetun already takes care of unsetting sensitive environment variables after reading them at start.

If you use Docker Compose or Docker Swarm, you can optionally use Docker secret files for all sensitive values such as your Openvpn credentials, instead of using environment variables.

The following secrets can be used:

• openvpn_user
• openvpn_password
• openvpn_clientkey
• openvpn_encrypted_key
• openvpn_key_passphrase
• openvpn_clientcrt
• httpproxy_user
• httpproxy_password
• shadowsocks_password

Note that you can change the secret file path in the container by changing the environment variable in the form <capitalizedSecretName>_SECRETFILE. For example, OPENVPN_PASSWORD_SECRETFILE defaults to /run/secrets/openvpn_password which you can change.
