Implementar el proxy de NetScaler CPX en Google Compute Engine

March 21, 2024
Contribución de: 
C

En esta guía de implementación, se 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 la funcionalidad completa de capa 7, la descarga de SSL, varios protocolos y la API de NITRO. NetScaler ADM proporciona soluciones de administración, licencias y análisis. Como servidor de licencias, NetScaler ADM otorga derechos a 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 con NetScaler ADM, la imagen CPX en Docker App Store (versión 11 o 12) se convierte en una instancia CPX completa. Sin licencia, la imagen CPX se convierte en una instancia CPX Express que admite conexiones SSL de 20 Mbps y 250.

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

Nota

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.

  1. Instala Docker en una VM de GCE.

  2. Configure la comunicación de API remota con la instancia de Docker.

  3. Instale la imagen de NetScaler CPX.

  4. Cree una instancia CPX.

  5. Licencia de NetScaler CPX a través de NetScaler ADM.

  6. 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, crea una VM Linux Ubuntu. A continuación, instale Docker en la VM mediante 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

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

Paso 3: instalar NetScaler CPX Image

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

Paso 4: crear una instancia de NetScaler CPX

Instale la imagen de NetScaler CPX en el host de 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\*\*

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

Suponiendo que NetScaler ADM se ejecute localmente, debería poder validar que NetScaler CPX se está comunicando con NetScaler ADM y enviando información. En las siguientes imágenes se muestra a 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 de Docker. A continuación, 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
