Implementar el proxy de NetScaler CPX en Google Compute Engine

April 1, 2025

Contribución de:

Esta guía de implementación describe cómo puede implementar NetScaler CPX con Docker en Google Compute Engine (GCE) de Google Cloud con NetScaler ADM ejecutándose dentro de la red empresarial. En esta implementación, NetScaler CPX instalado en GCE equilibra la carga de dos servidores back-end, y NetScaler ADM proporciona soluciones de licencias y análisis.

NetScaler CPX es un proxy basado en contenedores que admite funcionalidad completa de capa 7, descarga SSL, múltiples protocolos y API NITRO. NetScaler ADM ofrece soluciones de gestión, licencias y análisis. Como servidor de licencias, NetScaler ADM proporciona derechos para instancias de NetScaler CPX que se ejecutan en las instalaciones o en la nube.

CPX y CPX Express son las mismas imágenes. Cuando licencia e instala la imagen CPX mediante NetScaler ADM, la imagen CPX en Docker App Store (versión 11 o 12) se convierte en una instancia CPX completa. Sin una licencia, la imagen CPX se convierte en una instancia CPX Express que admite 20 Mbps y 250 conexiones SSL.

Requisitos previos

2 GB de memoria y 1 vCPU dedicada a NetScaler CPX
Código abierto de Docker disponible en GCE
NetScaler ADM se ejecuta en las instalaciones con conexión a Internet o VPN a GCE

Note

Para obtener información sobre cómo implementar NetScaler ADM, consulte Implementación de NetScaler ADM.

Pasos de configuración

Debe realizar los siguientes pasos para configurar esta implementación.

Instala Docker en una VM de GCE.
Configure la comunicación de API remota con la instancia de Docker.
Instale la imagen de NetScaler CPX.
Cree una instancia CPX.
Licencia de NetScaler CPX a través de NetScaler ADM.
Configure los servicios de equilibrio de carga en NetScaler CPX y verifique la configuración.
1. Instale los servidores web NGINX.
2. Configure NetScaler CPX para el equilibrio de carga y verifique la distribución de la carga a ambos servicios web.

Paso 1: Instalar Docker en una VM de GCE

Desde GCE, cree una máquina virtual Linux Ubuntu. Luego, instale Docker en la máquina virtual utilizando los comandos que se muestran en el siguiente ejemplo:

  $ sudo curl –ssl https://get.docker.com/ | sh
  % Total % Received % Xferd Average Speed Time Time Time Current
  Dload Upload Total Spent Left Speed
  0 0 0 0 0 0 0 0 --:--:-- --:--:-- --:--:-- 0curl: (6) Could not resolve host: xn--ssl-1n0a
  100 17409 100 17409 0 0 21510 0 --:--:-- --:--:-- --:--:-- 21492
  apparmor is enabled in the kernel and apparmor utils were already installed

  If you would like to use Docker as a non-root user, you should now consider
  adding your user to the "docker" group with something like:

  sudo usermod -aG docker albert\_lee

  Remember that you will have to log out and back in for this to take effect.

  WARNING: Adding a user to the "docker" group will grant the ability to run
  containers which can be used to obtain root privileges on the
  docker host.
  Refer to https://docs.docker.com/engine/security/security/\#docker-daemon-attack-surface
  for more information.

Paso 2: Configurar la comunicación de API remota con la instancia de Docker

Abra el puerto 4243 para la comunicación API con la instancia de Docker. Este puerto es necesario para que NetScaler ADM se comunique con la instancia de Docker.

   **cd /etc/systemd/system**
   **sudo vi docker-tcp.socket**
   **cat docker-tcp.socket**

  **Description=Docker Socket for the API

  $ **sudo systemctl enable docker-tcp.socket**
  Created symlink /etc/systemd/system/sockets.target.wants/docker-tcp.socket → /etc/systemd/system/docker-tcp.socket.
   **sudo systemctl enable docker.socket**

Paso 3: instalar NetScaler CPX Image

Obtenga la imagen CPX de NetScaler desde Docker App Store. El CPX Express y CPX tienen la misma imagen. Pero, cuando licencia e instala la imagen CPX usando NetScaler ADM, la imagen se convierte en una instancia CPX completa con 1 Gbps de rendimiento. Sin una licencia, la imagen se convierte en una instancia CPX Express que admite 20 Mbps y 250 conexiones SSL.

Paso 4: crear una instancia de NetScaler CPX

Instale la imagen CPX de NetScaler en el host Docker. Abra puertos para servicios específicos, como se muestra en el siguiente ejemplo, y especifique una dirección IP para NetScaler ADM:

  bash-2.05b\# **CHOST=${1:-localhost}**
  bash-2.05b\# **echo | openssl s\_client -connect $CHOST:443 | openssl x509 -fingerprint -noout | cut -d'=' -f2**
  depth=0 C = US, ST = California, L = San Jose, O = NetScaler, OU = Internal, CN = Test Only Cert
  verify error:num=18:self signed certificate
  verify return:1
  depth=0 C = US, ST = California, L = San Jose, O = NetScaler, OU = Internal, CN = Test Only Cert

Paso 5: Licencia de NetScaler CPX a través de NetScaler ADM

Suponiendo que NetScaler ADM se ejecuta en las instalaciones, debería poder validar que NetScaler CPX se esté comunicando con NetScaler ADM y enviando información. Las siguientes imágenes muestran NetScaler CPX recuperando una licencia de NetScaler ADM.

Paso 6: Configurar los servicios de equilibrio de carga en NetScaler CPX y verificar la configuración

Primero, instale los servidores web NGINX en el host Docker. Luego, configure el equilibrio de carga en NetScaler CPX para equilibrar la carga de los dos servidores web y pruebe la configuración.

Instalar servidores web NGINX

Use los comandos que se muestran en el siguiente ejemplo para instalar servidores web NGINX.

  $ sudo docker pull nginx
  Using default tag: latest
  latest: Pulling from library/nginx
  Digest: sha256:41ad9967ea448d7c2b203c699b429abe1ed5af331cd92533900c6d77490e0268
