An example monorepo project with local kubernetes deployment done on weekends since July until mid November 2020.
(These steps only apply to my environment, a guide will be publish once my blog engine is updated)
Before running, start the Ubuntu Server hosted on Hyper-V, minikube will start automatically, otherwise run the following command:
minikube start --insecure-registry "0.0.0.0/0"
Start the proxy that serves minikube on the port 8001 of the Ubuntu Server:
kubectl proxy --address='0.0.0.0' --disable-filter=true
Expose the local registry server:
kubectl port-forward -n kube-system $(kubectl get po -n kube-system | grep registry-wnppn | \awk '{print $1;}') 5000:5000 --address 0.0.0.0
The pods related to spots, already deployed, should be exposed with port-forwarding; first we get the pod names:
kubectl get po -n=spots
NAME READY STATUS RESTARTS AGE
spots-api-765999c867-mkz6s 1/1 Running 0 24d
spots-ui-5b584bb8b9-cfsw7 1/1 Running 0 24d
Then we apply the port-forwarding:
kubectl port-forward -n spots $(kubectl get po -n spots | grep spots-api-765999c867-mkz6s | \awk '{print $1;}') 3333:3333 --address 0.0.0.0
On windows, open Powershell with admin permissions, then apply the WSL Forwarding:
Enable-WSLForward
If you open $PROFILE, the described command is related to the following function:
function Enable-WSLForward {
Get-NetIPInterface | where {$_.InterfaceAlias -eq 'vEthernet (WSL)' -or $_.InterfaceAlias -eq 'vEthernet (Default Switch)' -or $_.InterfaceAlias -eq 'vEthernet (Ubuntu-VMSwitch)'} | Set-NetIPInterface -Forwarding Enabled
Write-Output "Forwarding enabled, printing interfaces..."
Get-NetIPInterface | select ifIndex,InterfaceAlias,AddressFamily,ConnectionState,Forwarding | Sort-Object -Property IfIndex | Format-Table
}
After that, open your Ubuntu (WSL 2) environment, then apply the context to kube-ctl.
kubectl config use-context ubuntu-hyper-v
* The context has the following configuration:
apiVersion: v1
clusters:
- cluster:
server: http://ubuntu-vm:8001
name: ubuntu-hyper-v
contexts:
- context:
cluster: ubuntu-hyper-v
user: devniel
name: ubuntu-hyper-v
current-context: ubuntu-hyper-v
kind: Config
preferences: {}
* The /etc/hosts has the following config:
# This file was automatically generated by WSL. To stop automatic generation of this file, add the following entry to /etc/wsl.conf:
# [network]
# generateHosts = false
127.0.0.1 localhost
192.168.1.15 host.docker.internal
192.168.1.15 gateway.docker.internal
127.0.0.1 kubernetes.docker.internal
192.168.0.2 ubuntu-vm
192.168.0.2 ubuntu-vm.registry.local
# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
Then open the directory of the monorepo and run the skaffold config with:
skaffold dev --port-forward
If everything works fine then the tail of the output should be:
