misc: update default dns command in tutorial

[rnjohn]

Type of Change

• Bug fix
• New feature
• Breaking change
• Documentation update

Motivation and Context

The tutorial.md file is very useful in getting started with container, but there is a command that might be outdated because it doesn't currently work (at least to me). The command present in the tutorial for setting the default DNS is this container system property set dns.domain test, but according to the --help flag of container, the current command to set the default DNS is as follows: container system dns default set test

Testing

• Tested locally
• Added/updated tests
• Added/updated docs

That's a good catch. It's actually the other way around. The documentation in main documents the code in main, and the container system property command replaced container system dns default following the 0.4.1 release.

If you look at https://github.com/apple/container/blob/0.4.1/docs/tutorial.md, you'll see the expected command.

This situation should be improved. I filed #638 to address making the current release documentation more discoverable.

@jglogan thank you for answering! English is not my first language so to verify, on version 0.4.1 it is supposed to be container system property? because that is the version of container that I installed and I had to use container system dns default

@rnjohn On container version 0.4.1 the correct command is container system dns default. Once we make a new package of container (which we do at the end of the month) and you update to that version, the command will then be container system property set dns.domain. Closing for now, please feel free to reopen the issue if we can clarify further. Thanks!
