dockerized instance in a K8 cluster network isnt ready

Have an issue with linuxgsm failing because the entrypoint.sh tries to download and install before the network is initialized.

can a delay be added to wait for a full response from the internet before it begins the processes in entrypoint-user.sh?

a simple while loop works but obviously not if I have to reload the docker image

```
#pause for network start
while ! ping -c 4 google.com > /dev/null;
do
echo -e "Waiting for internet connection."
sleep 10
done
```
