File microservice

File microservice to store files and their file-specific metadata

Running the file microservice

docker run --name mu-file-service \
    -p 80:80 \
    --link my-triple-store:database \
    -v /path/to/storage:/data \
    -e SECRET_KEY_BASE=my-secret-production-key-for-rails \ 
    -d semtech/mu-file-service

Configuration

The triple store used in the backend is linked to the login service container as database. If you configure another SPARQL endpoint URL through MU_SPARQL_ENDPOINT update the link name accordingly. Make sure the file service is able to execute update queries against this store.

The file service stores the files in the mounted volume /data. The maximum allowed file size can be configured through the MU_APPLICATION_MAX_FILE_SIZE environment variable (default: 20M).

The MU_APPLICATION_GRAPH environment variable (default: http://mu.semte.ch/application) specifies the graph in the triple store the file service will work in.

The SECRET_KEY_BASE environment variable is used by Rails to verify the integrity of signed cookies.

By default chunked encoding is disabled. It can be enabled by setting the environment variable STREAMING to 'true'. Streaming support is only available for mu-identifier >= 1.1.0 and mu-dispatcher >= 1.1.0.

API

  • GET /files/:id

Examples

  • To upload a file (assuming the service is running on localhost:80)
