Dockerfile fails ot produce XML output

[bjchambers]

Describe the bug

Trying to use docker to run tarpaulin and produce XML fails.

To Reproduce

docker run --security-opt seccomp=unconfined -v "${PWD}:/volume:rw" \
  xd009642/tarpaulin:develop-nightly \
  cargo build && cargo tarpaulin --out Xml

Produces the error: Error: "Failed to report coverage! Error: Failed to create run report".

No additional information is logged about why it failed. It had even produced coverage information already.

If I specify --output-dir=/volume the error changes to Error: "Failed to create or locate custom output directory: Some(\"/volume\")"

Expected behavior

The output file added to my local directory.

I believe this issue is around docker command chaining, the following seems to work for me:

docker run --security-opt seccomp=unconfined -v "${PWD}:/volume:rw" \                                                                                                                                                                                                                                                                                
  xd009642/tarpaulin:develop-nightly \
  /bin/bash -c "cargo build && cargo tarpaulin --out Xml"

See this small note in the docker docs.
