The containers in a Pod are automatically co-located and co-scheduled on the same physical or virtual machine in the cluster. The spec property includes any containers, storage volumes, or other pieces that Kubernetes needs to know about, as well as properties such as whether to restart the container if it fails. With this model a pod might hold multiple co-located containers that are tightly coupled and need to share resources.
Note that for the Pod, we define only nginx port 80. This time, the deployment should take place successfully, as the new security policy allows containers to run as any user, including the root user.
A pod's contents are always co-located, co-scheduled, and run in a shared context. Suited for backend services like databases, caches, etc. It is possible to create a pod with multiple containers inside it. Container dependencies and startup order Currently, all containers in a Pod are being started in parallel and there is no way to define that one container must be started after other container. If a node dies, the pods scheduled to that node are scheduled for deletion, after a timeout period. Also, more granular containers can be reused between teams.
kube - If the Kubelet or the container manager is restarted while waiting for processes to terminate, the termination will be retried with the full grace period. You can watch the video below: Creating the Kubernetes Manifest file Here is a simple manifest that creates 2 containers.
From there, as you can see, we have two values, v1 and Podmapped to two keys, apiVersion and kind. You can also specify more complicated structures by creating a key that maps to another map, rather than a string, as in: --- apiVersion: v1 kind: Pod metadata: name: rss-site labels: app: web In this case, we have a key, metadatathat has as its value a map with 2 more keys, name and labels. The labels key itself has a map as its value. You can nest these as far as you want to. Each list item under ports is itself a map that lists the containerPort and its value. Next we specify the metadata. The spec property includes any containers, storage volumes, or other pieces that Kubernetes needs to know about, as well as properties such as whether to restart the container if kubernetes create pod fails.

Instead, I could have fixed the repo so that Kubernetes could find what it was looking for, and it would have continued on as though nothing had happened. K8s, remember, manages container-based resources. For example, where we created a single instance of the Pod in the previous example, we might create a Deployment to tell Kubernetes to manage a set of replicas of that Pod — literally, a ReplicaSet — to make sure that a certain number of them are always available. Next we specify the kubernetes create pod. Finally, we get into the spec. You can find a full list of the in the. Templates are simply definitions of objects to be replicated — objects that might, in other circumstances, by created on their own.
