Great! That looks good. Shouldn't we set the 127-0-0-1 domain here as default? gitpod/install/preview/entrypoint.sh Line 33 in dbbb214 |

@corneliusludmann Agreed, and Updated! We should worry about flexibility later, as we are aiming for consistency across platforms now! |

coredns magic that makes the internal communication work!
|
My suggestion would be to keep the flexibility that allows overriding the domain with an env var but set 127-0-0-1.nip.io as default instead of the cluster IP domain. That would allow using a domain with the host IP to make it accessible in the network for colleagues but also to use the 127-0-0-1 approach. What do you think? |
Due to the way docker works in non-native platforms, It is very hard to have a consistent experience across all platforms as we can't just use the [docker bridge netwrok IP's in non-native platforms](https://docs.docker.com/desktop/networking/). This means that users have to search their Host IP, and use It to get up and working [which we tried, but understand that it's not a good UX](https://github.com/gitpod-io/website/pull/2349). But users can use `127-0-0-1.nip.io` as the DOMAIN which resolves to `127.0.0.1` and is available in all platforms as its `localhost`. This works well and good for all user communication but internal communication fails as `127-0-0-1.nip.io` for them is something else. So, This PR fixes that by adding new coredns `gitpod.db` coredns config essentially asking to route all `127-0-0-1.nip.io` to `proxy.default.svc.cluster.local`. [As k3s does not yet support overriding coredns config in a sane-way](k3s-io/k3s#462) ,We instead skip the default coredns by adding `coredns.yaml.skip` file, and adding our own `custom-coredns.yaml` which is just plain `coredns.yaml` that comes with `k3s`, added with gitpod config.

Description
Due to the way docker works in non-native platforms, It is
very hard to have a consistent experience across all platforms
as we can't just use the docker bridge netwrok IP's in non-native
platforms. This means that users have to search
their Host IP, and use It to get up and working
which we tried, but understand that it's not a good UX.
But users can use
127-0-0-1.nip.ioas the DOMAIN which resolves to127.0.0.1and is available in all platforms as itslocalhost. Thisworks well and good for all user communication
but internal communication fails as
127-0-0-1.nip.iofor themis something else.
So, This PR fixes that by adding new coredns
gitpod.dbcorednsconfig essentially asking to route all
127-0-0-1.nip.iotoproxy.default.svc.cluster.local. As k3s does not yet supportoverriding coredns config in a sane-way ,We instead skip the
default coredns by adding
coredns.yaml.skipfile, and adding our owncustom-coredns.yamlwhich is just plaincoredns.yamlthat comes with
