Description
Triggered this on create, but it is the same on run AFAIK.
If I am not mistaken, it seems to me that Docker is using:
^[a-zA-Z0-9][a-zA-Z0-9_.+-]+$ (seen in cli/cli/context/store/store.go)
while we use Validate from containerd/identifiers that only allows single separators followed by alpha num:
^[A-Za-z0-9]+(?:[._-](?:[A-Za-z0-9]+))*$
Steps to reproduce the issue
docker create --name nerdctl-teststartinteractive-create-false-false--true-false alpine
6d927047daa959bec273fd5945fd541b7e38a065e8b2ef0b196cafbb64f6c02e
nerdctl create --name nerdctl-teststartinteractive-create-false-false--true-false alpine
FATA[0000] invalid name "nerdctl-teststartinteractive-create-false-false--true-false": identifier "nerdctl-teststartinteractive-create-false-false--true-false" must match ^[A-Za-z0-9]+(?:[._-](?:[A-Za-z0-9]+))*$: invalid argument
Describe the results you received and expected
Consistency between docker and nerdctl.
Since we would make this more loose instead of stricter, I don't think it would be a problem.
Unless there is a reason to keep this behavior, I can send a PR to loosen this up.
We should also review everywhere we are using Validate, besides container names.
