Hyperion

[]

Description

hyperion creates a Cloud environment :

• Identical machine images creation is performed using Packer
• Orchestrated provisioning is performed using Terraform
• Applications managment is performed using Kubernetes

Kubernetes

Kubernetes master

• maintains the state of the Kubernetes server runtime
• API server
• Scheduler
• Registries (nodes, pod, service)
• Storage

Kubernetes nodes

• Represents the Host where containers are created
• Components : PODs, Kubelet, Proxy

Kubernetes components

• etcd : A highly available key-value store for shared configuration and service discovery.
• apiserver : Provides the API for Kubernetes orchestration.
• controller-manager : Enforces Kubernetes services.
• scheduler : Schedules containers on hosts.
• proxy : Provides network proxy services.
• kubelet : Processes a container manifest so the containers are launched according to how they are described.

Local

Usage

• Setup your Kubernetes configuration :

    $ export K8S_MASTER=x.x.x.x
    $ kubectl config set-cluster hyperion \
        --insecure-skip-tls-verify=true --server=${K8S_MASTER}
    $ kubectl config set-context hyperion --cluster=hyperion
    $ kubectl config use-context hyperion
  

• Check Kubernetes status :

    $ curl http://${K8S_MASTER}:8080/
    {
      "paths": [
         "/api",
         "/api/v1",
         "/api/v1beta3",
         "/healthz",
         "/healthz/ping",
         "/logs/",
         "/metrics",
         "/static/",
         "/swagger-ui/",
         "/swaggerapi/",
         "/ui/",
         "/version"
       ]
    }
  

• You could use the kubectl binary to manage your cluster :

    $ bin/kubectl version
    Client Version: version.Info{Major:"1", Minor:"0", GitVersion:"v1.0.3", GitCommit:"61c6ac5f350253a4dc002aee97b7db7ff01ee4ca", GitTreeState:"clean"}
    Server Version: version.Info{Major:"1", Minor:"0", GitVersion:"v1.0.3", GitCommit:"61c6ac5f350253a4dc002aee97b7db7ff01ee4ca", GitTreeState:"clean"}
  
    $ bin/kubectl get cs
    NAME                 STATUS    MESSAGE              ERROR
    controller-manager   Healthy   ok                   nil
    scheduler            Healthy   ok                   nil
    etcd-0               Healthy   {"health": "true"}   nil
  
    $ bin/kubectl get nodes
    NAME      LABELS    STATUS
    NAME          LABELS                               STATUS
    x.x.x.x       kubernetes.io/hostname=x.x.x.x       Ready
    x.x.x.x       kubernetes.io/hostname=x.x.x.x       Ready
  
    $ bin/kubectl cluster-info
    Kubernetes master is running at x.x.x.x:8080
  

• Creates namespaces :

    $ bin/kubectl -s ${K8S_MASTER}:8080 create -f namespaces/namespace-admin.json
    $ bin/kubectl -s ${K8S_MASTER}:8080 create -f namespaces/namespace-dev.json
    $ bin/kubectl -s ${K8S_MASTER}:8080 create -f namespaces/namespace-prod.json
  
    $ bin/kubectl -s ${K8S_MASTER}:8080 get namespaces
    NAME          LABELS             STATUS
    admin         name=admin         Active
    default       <none>             Active
    development   name=development   Active
    kube-system   name=kube-system   Active
    production    name=production    Active
  

Services

cAdvisor exposes a simple UI for on-machine containers on port 4194

For others services, see hyperion-services

Debug

Ping all hosts

$ ansible all -m ping -i <inventory>

Check connection to hosts

You could retrieve facts from hosts to check connections :

$ ansible all -m setup -a "filter=ansible_distribution*" -i <inventory>
