Couchbase en OpenShift 3

OpenShift es la plataforma PaaS de código abierto de Red Hat. OpenShift 3 proporciona una experiencia holística de ejecución de sus aplicaciones utilizando Docker y Kubernetes. Al estilo clásico de Red Hat, todo el trabajo se realiza en código abierto en OpenShift Origin. Esto también impulsa la próxima gran versión de OpenShift en línea y OpenShift Enterprise.

OpenShift 3 utilizando Docker y Kubernetes para la orquestación de contenedores hace que sea realmente sencillo hacer funcionar cualquier producto que tenga una imagen Docker con el mínimo esfuerzo. Este blog explica cómo empezar con Couchbase en OpenShift 3.

Primeros pasos con OpenShift 3

• Descargar la última Caja Vagrant (1,1 en el momento de escribir estas líneas) y Vagrantfile de: openshift.org/vm/. Cópialos en el mismo directorio.

  Vagrantfile está configurado para 2 GB de memoria y se puede actualizar si necesita ejecutar más contenedores. OpenShift Master, Node, Docker Registry y otros componentes se ejecutan dentro de la máquina virtual.

  Este blog fue escrito usando Vagrant 1.7.4 y VirtualBox 5.0.10r104061.

• Añade la Caja Vagrant:
  vagrant box add --name openshift3 openshift-bootstrap-1.1.box ==> box: Box file was not detected as metadata. Adding it directly... ==> box: Adding box 'openshift3' (v0) for provider: box: Unpacking necessary files from: file:///Users/arungupta/tools/openshiftv3/1.1/openshift-bootstrap-1.1.box ==> box: Successfully added box 'openshift3' (v0) for 'virtualbox'!

  vagrant box add --name openshift3 openshift-bootstrap-1.1.box ==> box: Box file was not detected as metadata. Adding it directly... ==> box: Adding box 'openshift3' (v0) for provider:     box: Unpacking necessary files from: file:///Users/arungupta/tools/openshiftv3/1.1/openshift-bootstrap-1.1.box ==> box: Successfully added box 'openshift3' (v0) for 'virtualbox'!

Descarga y configuración del cliente OpenShift 3

• Descargar Herramientas cliente Mac 64 bits (gem install rhc sólo para v2) de openshift.org/vm/ y extraerlos en un directorio. El listado se ve así:
  tar xzvf ~/Downloads/openshift-origin-v1.1-ac7a99a-darwin-amd64.tar.gz x ./ x ./oadm x ./kube-scheduler x ./kubelet x ./kube-apiserver x ./openshift x ./kube-controller-manager x ./kube-proxy x ./oc x ./kubectl
