Autoconfiguration of private network interface about docker-machine-vultr

[mtrofimm]

I'm testing with -vultr-os-id=160 (buntu 14.04 x64) and --vultr-private-networking=true.

one more test:

docker-machine create --driver vultr --vultr-api-key=myAPIKey --vultr-region-id=7 --vultr-plan-id=29 --vultr-ipv6=1 --vultr-private-networking=1 --engine-env DEV=1 testowa5

Auto-configuration of private network interface eth1 is already implemented. But only for machines that are created with the default RancherOS. For Ubuntu machines you can actually pass a Cloud-init userscript with the --vultr-userdata parameter.
Then you just have to write a bash script that configures the private interface.

Something similar to this (not tested):

#!/bin/sh

cat > /etc/network/interfaces <<EOF
auto eth1
iface eth1 inet static
    address 10.99.0.200
    netmask 255.255.0.0
    mtu 1450
EOF

ifup eth1

Pozdro 😄

[mtrofimm]

there is still some issue with autoconfiguration of rancheros. See my second test with default os.

pozdro.

This has been fixed in https://github.com/janeczku/docker-machine-vultr/releases/tag/v1.0.3.

Auto-configuration of private network interface eth1 is fully working again with RancherOS.
