Doesn't work...

I get this error with your first command:

```
"docker build" requires exactly 1 argument.
See 'docker build --help'.

Usage: docker build [OPTIONS] PATH | URL | -

Build an image from a Dockerfile
```

If I run the command as just docker build easywildcard it seems to work until the end when I get this:

```
fetch http://dl-cdn.alpinelinux.org/alpine/v3.11/main/x86_64/APKINDEX.tar.gz
ERROR: http://dl-cdn.alpinelinux.org/alpine/v3.11/main: temporary error (try again later)
WARNING: Ignoring APKINDEX.70f61090.tar.gz: No such file or directory

ERROR: unsatisfiable constraints:
The command '/bin/sh -c apk --update add bind' returned a non-zero code: 1
```

Reproduce the reported `docker build easywildcard` failure, then inspect the Dockerfile step containing `apk --update add bind` and the build command shown in the issue. Confirm whether the image can build successfully and the reported Alpine package-install error is resolved.
