How to install telnet into a alpine docker container. This is useful when using the celery remote debugger in a dev environment.

You could also setup a symlink and invoke telnetdirectly:

ln -s /usr/bin/busybox-extras /usr/bin/telnet
telnet localhost 6900

You could also setup a symlink and invoke telnetdirectly:

ln -s /usr/bin/busybox-extras /usr/bin/telnet
telnet localhost 6900

As far as I remember commands @Ryanb58 posted doesn't require it, because it will be automatically linked at the end of installation already
