Minikube installation steps on centos VM:

sudo install minikube-linux-amd64 /usr/local/bin/minikube
minikube start --addons=ingress --vm=true --memory=8192 --driver=none

    How you have started the Minikube on the VM ? Which command did you used ?

    If you are using the minikube --driver=docker it might won’t work.

    for starting the minikube on VM you have to change the driver

    minikube --driver=none

    in docker driver, it will create the container and install the kubernetes inside it and spawn the POD into further.

    Check more at : https://minikube.sigs.k8s.io/docs/drivers/none/

    if you on docker you can try :

    pkill docker
iptables -t nat -F
ifconfig docker0 down
brctl delbr docker0
docker -d

    "It will force docker to recreate the bridge and reinit all the network rules"

    reference : https://github.com/moby/moby/issues/866#issuecomment-19218300

    Try with

    docker run --net=host -it ubuntu

    Or else add dns in the config file in /etc/default/docker

    DOCKER_OPTS="--dns 208.67.222.222 --dns 208.67.220.220"

    Please check your container port and target port. This is my pod setup:

    spec:

 containers:

       name: hello

       image: "nginx"

  ports:

      containerPort: 5000

    This is my service setup:

     ports:

    protocol: TCP

        port: 60000

       targetPort: 5000

    If your target port and container port don’t match, you will get a curl: (7) connection refused error(Source).
