How to use docker hub registery with IKS deployed on VPC Gen2 infra?

I created a k8s cluster on IBM VPC Gen2 Infrastructure. When I deployed my application then it can't pull an image from docker hub. I'm getting below error. Port 443 is enabled under VPC Infrastucture/All Security groups/Rules. I can't find any documents which can help with this. All the docs are talking about setting up IBM registry and then push the docker image to this registry.

Error

Failed to pull image "metacontrollerio/metacontroller:v1.4.0": rpc error: code = Unknown desc = failed to pull and unpack image "docker.io/metacontrollerio/metacontroller:v1.4.0": failed to resolve reference "docker.io/metacontrollerio/metacontroller:v1.4.0": failed to do request: Head "https://registry-1.docker.io/v2/metacontrollerio/metacontroller/manifests/v1.4.0": dial tcp 107.23.X.X:443: i/o timeout

Mode of deployment

Please help.

Solution
    1. Go to https://cloud.ibm.com/vpc-ext/network/subnet.
    2. Select your VPC.
    3. Enable Public gateway(bottom corner) to allow worker nodes to access public internet.
