Redirect both the hostname and port for TCP connections

What is the version of your ORAS CLI

v1.0.0-rc.1

What would you like to be added?

The oras allows the flag --resolve host:port:address to dial to an another host, which works like /etc/hosts. However, it does not redirect the ports.

Therefore, it would be nice to have

--resolve host:port:address[:port]

Why is this needed for ORAS?

It is useful to do local development by using a local registry as a remote registry.

For example:

oras push --resolve registry.contoso.com:443:localhost:5000 registry.contoso.com/hello hello.txt

Are you willing to submit PRs to contribute to this feature?

• Yes, I am willing to implement it.

I think the example is wrong? In rc1, the push command looks like below

oras push --resolve registry.contoso.com:5000:localhost registry.contoso.com:5000/hello hello.txt

Since the default port of non-plain-http is 443, the destination port should be 443 and oras will map it to 5000. The command looks like below

oras push --resolve registry.contoso.com:443:localhost:5000 registry.contoso.com/hello hello.txt

The example in the description is exactly the same as you've provided.

Oh Indeed.
