not able to connect to internet from minikube pods-CodePudding

cluster info:

Minikube installation steps on centos VM:

curl -LO https://storage.googleapis.com/minikube/releases/v1.21.0/minikube-linux-amd64
sudo install minikube-linux-amd64 /usr/local/bin/minikube
minikube start --addons=ingress --vm=true --memory=8192 --driver=none

PODs of this minikube cluster are not able to connect to internet.

However My host VM has internet connection with no firewall or iptables setup.

Can anybody help me debug this connection refused error

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"

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"

You have to update the Git Config for proxy setting

Updated the http.proxy key in git config by following command

git config --global http.proxy http[s]://username:password@proxyaddress:port

Check out How to configure Git proxy for more details

If your username is an email address, which has @, also encode it to @.

git config --global http.proxy http[s]://username(encoded):password(encoded)@proxyaddress:port
