It is used to deploy container based applications automatically in cluster environment, apart from this it also used to manage Docker containers across the kubernetes cluster hosts.
Since security groups are stateful and the control plane security group comes with an outbound rule allowing access to everything, then why are we adding other inbound rules?
The Kubernetes Ingress resource can be backed up by any load balancer of your choice, so to leverage the Rancher's load balancing functionality, we have introduced the concept of a Rancher ingress controller.
But due to the fact a lot of pod properties are immutable, you will find this command more useful in next labs when dealing with other kubernetes objects.
Luckily for us, cloud providers such as AWS are helping to take care of these tedious tasks so we can focus on what is more important to us, like building apps.
Tip: In occassion we may find that killing a rogue pod gives a headache so I recommend using the force flag to get rid of them with a gracefu period.
Note: If you choose to increase the scale of your ingress, you will need to ensure that there are at least the equivalent number of hosts available in your Kubernetes environment that have the port available.
You may want to enable mutual TLS so the traffic between the source pod and the egress gateway will be encrypted.
Note: Minikube tends to use the latest version of Kubernetes so it will be advisable to grab the latest kubectl.
Configure kubectl for EKSNow that the tools are setup and the control cluster is deployed, we need to configure our kubeconfig file to use with EKS.
If an ingress is updated or service endpoints are changed, the ingress controller will update the corresponding Rancher load balancer to the changes in the ingress.
V2 of the metal and jazz services are out, and they now include the city each artist is from in the response.
In my case, kubectl is always using google's kubectl by gcloud tool, or there was most probably a conflict between Homebrew installed and Gcloud Installed kubectl.
As we can see in the above command output that our master node is not ready because as of now we have not deployed any pod.
Configure a Private Docker Registry on CentOS 7 For understanding Kubernetes (K8s) concepts and use it in your environment, we recommend that you should read Kubernetes in Action by Marko Luksa.
Download kubectl from the Tectonic Console, or from the Kubernetes release artifact site with the cURL tool.
As an administrator, you declare how you want the environment to look and kubernetes tries to make the real environment as close to your declaration as possible.
Kubeadm is one of the most common method used to deploy kubernetes cluster or in other words we can say it used to deploy multiple nodes on a kubernetes cluster.
In the current GA version, the OCI Container Engine for Kubernetes supports network block storage that can be shared across nodes with access permission RWOnce (meaning that only one can write, others can read only).
LTS system, where one system will act as Kubernetes Master Node and other two nodes will act as Slave node and will join the Kubernetes cluster.
