docker errors

[developmentkw]

I got two errors for docker, first one is a misspelling:

root@android-linux:~/docker/server# docker build -t barcodeAPIServer . ---> this I copied directly from the github readme

[+] Building 0.0s (0/0) docker:default ERROR: invalid tag "barcodeAPIServer": repository name must be lowercase

---

this error I get when I run the docker: root@android-linux:~/docker/server# docker run -p 9800:8080 -v $(pwd)/config:/config barcodeapiserver
