Example of Creating an Application from a Template

This section illustrates how you can provision an application with a PostgreSQL container and a Tomcat container. The PostgreSQL container contains a form that collects data. The Tomcat container stores the data that is collected.


Verify that you have perfomed the following steps:

  • Deployed a virtual container host (VCH).
  • Have a vCenter Server Single Sign-On user account with vSphere administrator privileges, or a user account that has been granted the Management Portal Administrator role in vSphere Integrated Containers.
  • Created a project, assigned users to the project, and added the container host to the project.
  • Created a volume with the name webapp and network with name web.

Create an Application Template

Create an application template and add a PostgreSQL container and a Tomcat container to it.

Perform the following steps:

  1. In the management portal, navigate to Deployments > Applications and click +Application.
  2. On the Create a Template page, enter the application name Postgres-DB-Application and click Proceed.
  3. In the Edit Template page, click Add Container and add a postgres container. For the steps to create the postgres container, see Example of Provisioning a Single Container.
  4. In the Edit Template page, click Add Container. Add a tomacat container.
  5. Select the select the tutum/tomcat container and click Continue.
  6. On the Basic tab, configure the following settings for the container:
    1. Image. The image that you want to instantiate the container from. This displays registry.hub.docker.com/tutum/tomcat. Select latest under tags.
    2. Name. Enter tomcat.
    3. Command. Enter curl -o https://tomcat.apache.org/tomcat-6.0-doc/appdev/sample/sample.war.
  7. On the Network tab, configure the following settings:
    1. Port Bindings. Enter 8080 for Host Port and 80 for Container Port.
    2. Networks. Select web.
  8. On the Storage tab, in Volumes, enter webapp for Host and /usr/local/tomcat/webapps for Container.
  9. On the Policy tab, select Always as the Restart Policy.
  10. Click Add to add the container.
