What is Kubernetes? is a technology that allows to orchestrate docker containers componenetes: control plane Node Scheduler kube-proxy kubelet etcd controller manager Cloud controller manager Api server notes for using kubernets requirements: docker install kubectl and kubernetes have docker installed to use or practice using minikube to start minikube running : sudo sysctl fs.protected_regular=0 sudo minikube start commands can now be executed [run as root] most used commands kubectl config get-contexts kubectl get ns [show pods] kubectl -n kube-system get pods [you can pass more commands like -o wide] kubectl delete pod "pod name" kubectl delete -f "file name" [delete the pods that the file creates] kubectl get pod "pod name" [to see the state of the pod, you can pass -o yaml and it will show all the yaml of the pod ] kubectl describe pod "pod name" kubectl get pvc kubectl delete pvc "pvc name" kubectl get sts kubectl delete sts "statefulset name" manifests [to understand review 01-pod....

Un playbook es un archivo donde se escribiran todas las tareas que quieres que se hagan con ansible es escrito en yml y es mas facil porque solo tendremos que ejecutarlo no tendremos que escribir cada comando y recordarlo. Primer paso crearemos una archivo llamado tareas.yml segundo paso escribiremos el siguiente codigo: --- - hosts: all name: creando un playbook become: true task: - name: instala vim apt: name=vim state=present - name: comando shell shell: echo hola - name: detiene servicio service: name=nginx state=stoppeda - name: start servicio service: name=nginx state=started – [En la variable hosts podemos especificar ip/dominio igual podemos colocar el nombre de los grupos a los que queremos que se les apliquen estos cambios]...
