when open the second project, lsp-docker tries to start another container with the same name.
/usr/bin/docker: Error response from daemon: Conflict. The container name "/lsp-container-2" is already in use by container "47f937f70efa5a6dba94c3ea5fd36a445fbe0c2c8303f6975660a53725a5ff44". You have to remove (or rename) that container to be able to reuse that name.
See '/usr/bin/docker run --help'.
