v0.6.2 breaks custom network setup

[drallgood]

Description

I had set up a bridged network so that I can have a custom bridged interface with a static IP (I need this so I can run a DNS server.. otherwise it would interfere with mDNS on the host system).

v0.6.2 broke this, because it overrides the network.yml file with a static one, so the "briged" network isn't defined anymore, which the override.yml references.

Result:
errors inspecting instance: [field networks[2].lima references network "bridged" which is not defined in networks.yaml]

Version

Output of colima status

No response

Reproduction Steps

1. create .colima/_lima/_config/override.yaml & define a new bridged network
2. start colima

Expected behaviour

No response

Additional context

Additional information:

override.yml:

networks:
  - lima: bridged

Problem is that .colima/_lima/_config/networks.yaml now gets overridden with a default every time. So you can't specify anything custom in there

Are you customizing the network.yaml file solely for the purpose of using a bridged network?

[drallgood]

yes.

@drallgood Were you able to get this resolved? I have a similar problem.

[heijligers]

same here

[drallgood]

No I was not so far. Currently I'm downgrading to 0.6.1

A bridged network with a fixed IP to be precise. I need it for a DNS server

@abiosoft Still can't upgrade because of this.
Any suggestions for a workaround?

[abiosoft]

Looks like I can finally get to this.

The main reason why a fixed IP address is not encourage is due to the fact that you can have multiple (profile) instances running and can cause undesired behaviour when there is a clash of IP address.

[abiosoft]

As a side note, the assigned IP address should be fixed and not change afterwards. Unless an extra profile is created.

Good point. Doesn't solve the problem though. I need a fixed, externally assigned (or configurable) IP that cannot change later.
Anything else won't do it for a DNS server. UDP forwards won't work as port 53 is already taken on the host machine (and no other port is allowed for this so I can't even use a random port).
I've tried everything else and none of it worked.

Until then I'm stuck on older versions of Colima.

@drallgood can you share your current networks.yaml file?
Or you only utilise the override file.

@abiosoft Here's the networks.yml
It's mostly the default one from before v0.6.2

The static IP address assignment is handled by the DHCP server in my network

# Path to socket_vmnet executable. Because socket_vmnet is invoked via sudo it should be
# installed where only root can modify/replace it. This means also none of the
# parent directories should be writable by the user.
#
# The varRun directory also must not be writable by the user because it will
# include the socket_vmnet pid file. Those will be terminated via sudo, so replacing
# the pid file would allow killing of arbitrary privileged processes. varRun
# however MUST be writable by the daemon user.
#
# None of the paths segments may be symlinks, why it has to be /private/var
# instead of /var etc.

The feature is being added #1382.
