Missing rundemo.sh file

[swinslow]

After building the democurl container (and the other qmstr containers), README.md says to run the following command:

./rundemo.sh

However, rundemo.sh is not (currently) present.

Trying to run the democurl container using docker run qmstr/democurl results in the following error:

docker: Error response from daemon: OCI runtime create failed: container_linux.go:348: starting container process caused "exec: \"/demos/curl/entrypoint.sh\": stat /demos/curl/entrypoint.sh: no such file or directory": unknown.
