Cannot create deployment of nginx tasks definitions on AWS Fargate using virtual-kubelet - amazon-web-services

Question

I am unable to to deploy nginx containers using kubectl to AWS Fargate using virtual-kubelet. I am following this guide: https://aws.amazon.com/blogs/opensource/aws-fargate-virtual-kubelet/.
I am having an issue with Step 6: Create Kubernetes objects.
I would like to know why the nginx containers are PENDING and why the AWS Fargate task definitions have not been created.
The following is some of my commands I used. I can give more detail upon request.
# ./virtual-kubelet --provider aws --provider-config fargate.toml
...

Update:
I then ran the command to add the nodeSelector to my nodes using the following command for each node:
kubectl label nodes ip-172-20-47-15.eu-west-2.compute.internal type=virtual-kubelet
type=virtual-kubelet is the nodeSelector specified in the manifest file, nginx-deployment.yaml.

Now when I go to the AWS Fargate Dashboard the associated task definitions are not created as shown in the tutorial.

Answer 1

This issue is resolved. I was able to create the AWS Fargate definitions by adding the ALB Security group to the fargate.toml file and by adding tolerations to the nginx.deployment.yaml file as shown below:
apiVersion: apps/v1
kind: Deployment
metadata:
name: nginx-deployment
labels:
app: nginx
spec:
replicas: 3
selector:
matchLabels:
app: nginx
template:
metadata:
labels:
app: nginx
spec:
containers:
- name: nginx
image: nginx:1.7.9
tolerations:
- key: virtual-kubelet.io/provider
operator: Equal
