How to configure the default --network?

[rgl]

Is there a way to configure the default network used by nerdctl? I'm trying to use nerdctl with k0s configured containerd, where the default network is called mynet and always having to use nerdctl --network=mynet is a nuisance.

By reading the docs at https://github.com/containerd/nerdctl/blob/master/docs/config.md I did not find a way.

emmmm, If I remember correctly, we don't have the way to explicitly spec an existed CNI network config as the default network. Maybe we can make this a feature? cc @junnplus

SGTM

We can append this list https://github.com/containerd/nerdctl/blob/master/docs/config.md#properties by either adding a new field in config.toml file or CLI env var to set the default network

SGTM, I'm working on it

• persist default network config #1092

A little different, #1092 just persists the default network(bridge), the user can modify it, but @rgl may want to specify a different default network than bridge.

I would like to configure nerdctl to use an existing network (e.g. created by k0s/kube-router) without using the - -net cmd line parameter (but if it is specified, it would use it instead of the default network set in the config or environment variable (if that exists at all)).
