[rajks24]

I have got the softwares installed in bootstrap VM

1. kubectl
2. go
3. kustomize
4. kubebuilder

Have access to running kubernetes cluster build with kubeadm

while install, getting the below error

Hi @rajeshsingh624, I've recently pushed a fix which unlinks libc: https://github.com/monzo/egress-operator/pull/18 Any chance this helps your case?

Any idea why ? also do we need to install gcc separately on ubuntu 18 ?

Please use below commands just after the git clone to resolve this:

1. Get repository to push images as mentioned in readme
2. Install Kubebuilder for code generation as mentioned in readme
3. Get CoreDns (default with k3s) pod running as mentioned in readme
4. Install Golang as mentioned in readme
5. To install Kustomize for building the Kubernetes manifests :
   • curl -s "https://raw.githubusercontent.com/kubernetes-sigs/kustomize/master/hack/install_kustomize.sh" | bash
   • sudo install -o root -g root -m 0755 kustomize /usr/local/bin/kustomize
6. apt-get install build-essential (for installing gcc)
7. apt-get install make
8. make install
9. make run (after cd egress-operator)
