The DMOD project has two related sets of dependencies:
- those needed to run and use a DMOD deployment
- those needed for development work
| Dependency | Constraints | Notes |
|---|---|---|
| Docker Engine | >=20.10.16 | Docker Swarm support required (i.e., alternatives without this, like Podman, are insufficient) |
| Docker Compose | >=2.0.x | See issue #133; deployx plugin now required as noted below |
| deployx Docker plugin | >=0.0.1 | Available here. Results in some transitive dependencies not explicitly enumerated here (e.g., Go) |
| Bash | >=3.2.57 | |
| OpenSSL / LibreSSL | >=3.0.0 / >=2.8.3 | |
| MinIO CLI client |
| Dependency | Constraints | Notes |
|---|---|---|
| Usage Dependencies | Same as above | |
| Python | >=3.8.x | |
| Python Pip | Analogous to installed Python version | |
| Python Development Headers/Libs | Analogous to installed Python version | Required for building certain Python dependency wheels; e.g., pandas |
| C++ Compiler | Required for building certain Python dependency wheels; e.g., pandas | |
| Python Packages | See requirements.txt | Recommend installing in Python virtual environment |
The strictness of these dependencies can vary in different situations, in a way that is hard to define concisely. E.g., one could probably avoid installing Bash by manually performing all the tasks handled by Bash scripts 1. Also, OpenSSL is not needed (locally) if all required SSL certificates can be provided from elsewhere. And somewhat related: multi-node deployments probably don't need all dependencies on the non-primary node(s).
As a general rule, however, it is highly recommended to begin by installing all documented dependencies, until a user understands where and why any exception applies.
