| Advantages Docker: | |
| * Same config for development and production | |
| * Manage dev/prod environment cleanly only via docker-compose files | |
| * No configmanagement necessary - just pass environment variables | |
| Disadvantages Docker: | |
| * Rebuilding images takes long on Raspberry PI | |
| * Building ARM Docker images on non-Raspberry PI build host is complex | |
| * Cannot host private Docker images on docker hub for free - need to run own Docker image hub | |
| Advantages SystemD: | |
| * Integrates cleanly and natively into Debian system | |
| * Fast to roll out updated config using config management - only config diff is applied | |
| * Better tooling to analyze and log running SystemD services | |
| * Better and more fine-granular service dependencies | |
| Disadvantages SystemD: | |
| * Configuration inconsistencies between development (Docker) and production (SystemD+Config management) |
