- `--cluster` flag parsed for `https://` prefix and node creation treated differently accordingly
- new `--network` string array flag to add the node to multiple networks (primary network when adding to a remote cluster)
- new `--token` flag to provide the cluster token
- before starting the cluster, gather environment info via tools node
- use hostIP/gatewayIP for DNS (iptables + resolv.conf updated in entrypoint script)
- revamp of custom entrypoint scripts
- remove`--no-hostip` flag and the related `disableHostIPInjection` config option
- inject host IP on every cluster startup (except when hostnetwork is chosen)(/etc/hosts + CoreDNS)
- inject host entries for every cluster network member container into the CoreDNS configmap
This comes with several fixes/improvements
- only consider containers that have the default object label (app=k3d)
- handle network deletion
- check if there are other k3d containers connected
- if there are only registries, disconnect them
- if there are non-registry nodes, leave everything as it is
- if there are any containers connected, that are not automatically
disconnected, log a warning and continue
Before, we just looked up the name of the docker network, causing docker
to do some sort of relaxed matching (prefix?) which could cause k3d to
choose the first matching network instead of the exact match.
Now we're enforcing exact Regex matching to prevent this.
Fixes#374
