So I used my Docker Desktop installation (sudo docker version (please see screen copy) ) to try the example “$ docker run busybox echo hello world” (p 86)
but I get an error message “hello”" does not seem to exist in busybox anymore (please see screen copy) ? Whats happening?
Sinc we are not talking about Docker Desktp anymore, I moved your last post to this new topic.
Regarding play with Docker, you are using the wrong URL probably, but you forgot to mention where you found that link or what it means that you “can’t create the training environment”.
If you google for Play With Docker, you can find this:
And click on the options there. When something doesn’t work, share what exactly and where you found it.
Regarding the error messages, if you start running commands randomly, you will have lots of error messages. Pay attention to tutorials and run exactly what those suggest. When you do and commands still don’t work, share a link to a page where you saw the instruction so we know whether it is wrong or you are doing something wrong
If you wuote a command to me which you never even executed and say you got an error message which you actually got when you run another actually wrong command after you executed anoter wrong command which you fixed by removing “echo”, how could we help? Again, pay attention to all words in a tutorial. The command you quoted is right, just execute it and not the wrong one.
