Docker errors when spaces or uppercase chars in src path

• Error if uppercase in src file path:

wskdebug hello Uppercase/hello.js
Error: Command failed: docker run -d --name wskdebug-hello-1564994363895 --rm -m 268435456 -p 8080 -p 9229:9229 -v /Users/xxxx/demos/Uppercase/hello:/code adobeapiplatform/adobe-action-nodejs-v10:3.0.13 node --expose-gc --inspect=0.0.0.0:9229 app.js
docker: invalid reference format: repository name must be lowercase.
See 'docker run --help'.

This might be still ok as docker's error is pretty specific

• Error when space:

wskdebug hello "space path"/hello.js
Error: Command failed: docker run -d --name wskdebug-hello-1564994363895 --rm -m 268435456 -p 8080 -p 9229:9229 -v /Users/xxxx/demos/space path/hello:/code adobeapiplatform/adobe-action-nodejs-v10:3.0.13 node --expose-gc --inspect=0.0.0.0:9229 app.js
docker: invalid reference format.
See 'docker run --help'.

This is not ok as there is no mention of what caused the error

These are two instances of the same issue - a space in the path. The uppercase message is just a confusing side aspect, since Docker parses the docker run command line not as intended.

For me the first happens if the space is in a higher directory

-v /Users/alex/Work/code/nui/wskdebug/examples/with space/Uppercase:/code

whereas the second happens if the leaf directory has a space:

-v /Users/alex/Work/code/nui/wskdebug/examples/with space:/code

I assume in your example the left out xxxx has spaces as well.

The problem is that the -v mount argument to docker run was not properly enclosed with quotes. See also here.

Fixed in bf8cfff.
