Colima is not able to access local network connections after mac update

[ibuiltthis]

Description

Colima containers are not able to access the local network.

Possible cause: After recent macos updates, local network access for applications must be specifically enabled via System Settings. (Privacy and Security -> Local Network) I had to explicitly enable it for "Docker" however there is Calima doesn't appear in the list of options to be enabled.

Reproduction Steps

1. Run any container
2. ping any computer on the local network

Expected behaviour

The local computer should be able to be reached by the container

Additional context

No response

Go to System Settings -> Privacy & Security -> Local Network and make sure the relevant Docker application has local network access enabled. Although Colima may not be on the list, Docker's settings may affect it. In addition, you can actually use servbay to replace docker, which is easier to use on mac than tools such as docker and mamp

Local Network is enabled for Docker. I need to reach a server on our local network and I need to stick to a container based approach.

check : #711 and make sure you can reach it. It may be a resolution issue.

I met the similar problem. I couldn't push docker image to a registry in a local network by IP address. The workaround for me is setting network.address to true in ~/.colima/default/colima.yaml

# Network configurations for the virtual machine.
network:
  # Assign reachable IP address to the virtual machine.
  # NOTE: this is currently macOS only and ignored on Linux.
  # Default: false
  address: true

I see the above various timeouts connecting to a private Artifactory instance over VPN, on Mac OS 15.1. There were no issues prior to the Sequioa upgrade. network.address: true and network.dns: [ <my internal DNS> ] unfortunately don't improve anything. Using Docker Desktop instead of Colima does work, so my Artifactory instance and other networking are fine.

And unlike the OP, Colima does appear in my System Settings → Privacy & Security → Local Network, and I have given it access. I also added & enabled it under Developer Tools (which seemed to be required for Docker Desktop, FWIW) and Full Disk Access to no effect. A complete reinstall of Colima including the removal of ~/.colima/ also made no difference.

I have a similar issue after upgrading to Sequoia 15.1. Pulling images from a registry behind a VPN does not work anymore with colima flag --network-address.

Error message is similar to the previous poster, e.g. net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers).

However, if network-address flag is not set, pulling works fine.

Reinstalling colima, using dev version, deleting profiles and colima/lima related files did not help.
For me, colima does not apppear under System Settings → Privacy & Security → Local Network.

Can you share the output of colima ssh -- ip route after starting Colima with network address enabled?

You should get something like the following

default via 192.168.106.1 dev col0 proto dhcp src 192.168.106.2 metric 100
default via 192.168.5.2 dev eth0 proto dhcp src 192.168.5.1 metric 200
...

What happens if you delete the entry for the network address?

colima ssh -- sudo ip route del default via 192.168.106.1

colima ssh -- sudo ip route del default via 192.168.106.1

This fixes the issue as a workaround - I can still reach colima from my host with network-address and pulling images in colima from the Registry behind VPN works.

[abiosoft]

@f-helm if that indeed resolves it, then an update can be pushed to enforce the behaviour.

I would wait for confirmation from others as well.

[paraniraja]

above workaround works for me as well

[bostjanl-better]

I had the same issue, the workaround above also fixes it for me

[abiosoft]

I think we've got enough confirmations, would go ahead with the fix.

[mironnn]

Also have this issue. Waiting for the fix.
thanks

[kizzie]

Heya! Also had this issue and that fix deleting the routing table entry worked for me!

The same issue after updating to 15.1, removing the routing solves the issue.
