olca-ipc-container

This repository contains an example for packaging an openLCA v2 IPC server in a Docker container. This is done in a multi-stage build where the final image only contains the necessary resources to run the server. To build the image, just run:

cd olca-ipc-container
docker build -t olca-ipc-server .

This will package the IPC server and native calculation libraries in an image tagged as olca-ipc-server. The following example will start a container from that image:

docker run \
  -p 3000:8080 \
  -v $HOME/openLCA-data-1.4:/app/data \
  --rm -d olca-ipc-server \
  -db example --readonly

This will start the server in the container at port 8080 using /app/data as data folder. The data folder is mapped to the default openLCA workspace in the example and the port to 3000 of the host. More options can be passed in to the container after the image name (olca-ipc-server). In the example, the database is set to example (so ~/openLCA-data-1.4/databases/example would be the full path of the database) and the server is run in readonly mode.

The server implements the JSON-RPC protocol of the openLCA API (see https://greendelta.github.io/openLCA-ApiDoc/ipc/). Here is an example curl command to list the product systems via the API:

curl -d '{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "data/get/descriptors",
  "params": { "@type": "ProductSystem" }}'\
  -H "Content-Type: application/json"\
  -X POST http://localhost:3000
