Never hardcode sensitive information such as passwords, API keys, or authentication tokens in source code, configuration files, or container definitions. These can be exposed through version control systems, shared repositories, or compromised container images.

Instead:

1. Use environment variables or secure runtime configuration
2. Implement a secrets management solution
3. For Docker specifically, utilize build arguments that aren’t persisted in the final image

Example - Instead of:

FROM n8nio/n8n

ENV N8N_BASIC_AUTH_ACTIVE=true
ENV N8N_BASIC_AUTH_USER=Tre
ENV N8N_BASIC_AUTH_PASSWORD=Npt9854$

Better approach:

FROM n8nio/n8n

ENV N8N_BASIC_AUTH_ACTIVE=true
# Credentials will be provided at runtime
# docker run -e N8N_BASIC_AUTH_USER=username -e N8N_BASIC_AUTH_PASSWORD=password n8n-image

For build-time configuration, use ARG instead of ENV for sensitive values that shouldn’t persist in the image.
