Linting Results

Severity	File	Description
ℹ️	bitcoin-knots/docker-compose.yml	Mounted file/directory "/bitcoin-knots/torrc" doesn't exist: The volume "${APP_DATA_DIR}/torrc:/etc/tor/torrc:ro" tries to mount the file/directory "/bitcoin-knots/torrc", but it is not present. This can lead to permission errors!
ℹ️	bitcoin-knots/docker-compose.yml	External port mapping "${APP_BITCOIN_KNOTS_P2P_PORT}:${APP_BITCOIN_KNOTS_INTERNAL_P2P_PORT}": Port mappings may be unnecessary for the app to function correctly. Docker's internal DNS resolves container names to IP addresses within the same network. External access to the web interface is handled by the app_proxy container. Port mappings are only needed if external access is required to a port not proxied by the app_proxy, or if an app needs to expose multiple ports for its functionality (e.g., DHCP, DNS, P2P, etc.).

ℹ️	bitcoin-knots/docker-compose.yml	Potentially using unsafe user in service "server": The default container user "root" can lead to security vulnerabilities. If you are using the root user, please try to specify a different user (e.g. "1000:1000") in the compose file or try to set the UID/PUID and GID/PGID environment variables to 1000.
