ipv4check setup

ipify-like endpoint used for checking public ipv4 ip addresses

• edit these files to have the public dns name of ipv4check host

  • docker/nginx.conf
  • ingress/ingress-route.yaml

• edit this file to have the correct ip for the INGRESS_CONTROLLER_IP

  • ingress/create-ipv4check-ingress.sh

• edit docker/nginx.conf to have the correct public FQDN you'll be using for ipv4check

• log into docker.io and create a repo to host the ipv4check image

• build the docker image and send it to docker.io

  cd docker
  
  docker login -u {YOUR_USERNAME}
  
  docker build . -t {YOUR_USERNAME}/{REPONAME}:v1.0
  
  docker push {YOUR_USERNAME}/{REPONAME}:v1.0
  

• update the deployment yaml to point at your new image

  • deployment/ipv4check-deployment.yaml

    example:

      image: {YOUR_USERNAME}/{REPONAME}:v1.0
    

• create k8s name space

  • deploy ipv4check-namespace.yaml

    kubectl apply -f ipv4check-namespace.yaml
    

    OR

  • run kubectl command

    kubectl create namespace ipv4check
    

• create deployment

  kubectl apply -f deployment/ipv4check-deployment.yaml
  

• create service

  kubectl apply -f service/ipv4check-service.yaml
  

• create ingress

  cd ingress && ./create-ipv4check-ingress.sh
