# cem-grpc4bmi

Set up a [grpc4bmi](https://grpc4bmi.readthedocs.io) server

to run a containerized version

of the [CEM](https://csdms.colorado.edu/wiki/Model:CEM) model

through Python.

## Build

Build this example locally with:

```

docker build --tag cem-grpc4bmi .

```

The image is built on the [csdms/grpc4bmi](https://hub.docker.com/r/csdms/grpc4bmi) base image,

which is built on the [condaforge/miniforge3](https://hub.docker.com/r/condaforge/miniforge3) base image.

The OS is Linux/Ubuntu.

The CEM model, grpc4bmi, and the grpc4bmi server are installed in `/opt/conda`.

The CEM grpc4bmi server is exposed through port 55555.

## Run

Use the grpc4bmi Docker client to access the BMI methods of the containerized model.

Install with *pip*:

```

pip install grpc4bmi

```

Then, in a Python session, access CEM in the image built above with:

```python

from grpc4bmi.bmi_client_docker import BmiClientDocker

m = BmiClientDocker(image="cem-grpc4bmi", image_port=55555, work_dir=".")

m.get_component_name()

del m  # stop container cleanly

```

If the image isn't found locally, it's pulled from Docker Hub

(e.g., try the `csdms/cem-grpc4bmi` image).

For more in-depth examples of running the CEM model through grpc4bmi,

see the [examples](./examples) directory.

## Developer notes

A versioned, multiplatform image is hosted on Docker Hub

at [csdms/cem-grpc4bmi](https://hub.docker.com/r/csdms/cem-grpc4bmi).

This image is automatically built and pushed to Docker Hub

with the [release](./.github/workflows/release.yml) CI workflow.

The workflow is only run when the repository is tagged.

To manually build and push an update, run:

```

docker buildx build --platform linux/amd64,linux/arm64 -t csdms/cem-grpc4bmi:latest --push .

```

A user can pull this image from Docker Hub with:

```

docker pull csdms/cem-grpc4bmi

```

optionally with the `latest` tag or with a version tag.
