To build a Docker image and test the command

1. Create a directory, say mkdir /path/to/dir, and place in it the 2 files below (Dockerfile and test-upload.sh). You'll also need a sample coverage file (not included here).
2. In Dockerfile, update the WORKDIR /path/to/dir line with the actual path to your new directory.
3. In test-upload.sh, update the ./coverage.xml path with the actual path to a test coverage file.
4. Navigate to the new directory cd /path/to/dir.
5. Build the test-upload image: docker build -t test-upload ..
6. Using your project's CODACY_PROJECT_TOKEN, run the new image docker run --env CODACY_PROJECT_TOKEN=<your-token> test-upload

Dockerfile

FROM alpine:latest

WORKDIR /path/to/dir
COPY . .

ENTRYPOINT ["./test-upload.sh"]

test-upload.sh

#!/bin/sh

wget -qO - https://coverage.codacy.com/get.sh | sh -s -- report -r ./coverage.xml
