Eclipse Che on WSL2

eclipse-che-wsl2.sh

# start a Minikube instance
minikube start --addons=ingress --driver=docker --memory=12288 --cpus=6

# deploy Eclipse Che
chectl server:deploy --platform=minikube

# configure network

## 1. edit /etc/hosts in WSL2 (warning: this will not persist across WSL restarts)
echo "127.0.0.1\t$(minikube ip).nip.io" | sudo tee -a /etc/hosts
echo "127.0.0.1\tdex.$(minikube ip).nip.io" | sudo tee -a /etc/hosts

## 2. edit /etc/hosts in Windows hosts
## next line must be run with administrative rights (for instance launch Windows Terminal as administrator)
echo "127.0.0.1\t$(minikube ip).nip.io" | sudo tee -a /c/Windows/System32/drivers/etc/hosts # path could also starts with /mnt/c instead of /c
echo "127.0.0.1\tdex.$(minikube ip).nip.io" | sudo tee -a /c/Windows/System32/drivers/etc/hosts # path could also starts with /mnt/c instead of /c

## 3. add reverse entries in Core DNS
kubectl get configmap coredns -n kube-system -o json | sed "s[hosts {[hosts {\\\\n       $(echo `kubectl run -it --rm coredns-fix --image=alpine --restart=Never -- sh -c 'getent hosts host.docker.internal'` | awk '{ print $1 }') $(minikube ip).nip.io[" | kubectl replace -f -
kubectl get configmap coredns -n kube-system -o json | sed "s[hosts {[hosts {\\\\n       $(echo `kubectl run -it --rm coredns-fix --image=alpine --restart=Never -- sh -c 'getent hosts host.docker.internal'` | awk '{ print $1 }') dex.$(minikube ip).nip.io[" | kubectl replace -f -

# export Eclipse Che Certificate Authority (to be imported in end-user browser)
chectl cacert:export

# pull the (huge) Docker image used by DevWorkspaces in the Minikube Docker daemon
eval $(minikube docker-env)
docker pull quay.io/devfile/universal-developer-image:ubi8-latest

# start the Minikube tunnel
minikube tunnel

# open the Eclipse Che Dashboard
chectl dashboard:open

I used to have this issue too.

Check the new version of the Gist, especially:

kubectl get configmap coredns -n kube-system -o json | sed "s[hosts {[hosts {\\\\n       $(echo `kubectl run -it --rm coredns-fix --image=alpine --restart=Never -- sh -c 'getent hosts host.docker.internal'` | awk '{ print $1 }') $(minikube ip).nip.io[" | kubectl replace -f -
kubectl get configmap coredns -n kube-system -o json | sed "s[hosts {[hosts {\\\\n       $(echo `kubectl run -it --rm coredns-fix --image=alpine --restart=Never -- sh -c 'getent hosts host.docker.internal'` | awk '{ print $1 }') dex.$(minikube ip).nip.io[" | kubectl replace -f -

basically it updates the hosts section in the CoreDNS configuration (you might need to delete the CoreDNS pod to recreate a pod with the new configuration).

Instead of resolving dex.192.168.49.2.nip.io to 127.0.0.1, it will resolve as the Docker host IP as seen from inside a Kubernetes pod.

Hi @debovema,

awesome script.
I'm using containerd as the container runtime.
Can you point me in the right direction on what I need to do?

Merci

Update:

I followed your commands except for the last two.
Accessing Eclipse Che from localhost works though!
