How to configure the default web URL port for containers and applications in Container Station 3?

Release date: 2022-11-16

Container Station helps you centrally build, run, and manage Docker containers and Docker Compose applications on your QNAP device.

You can specify a default port for each container and application that Container Station uses to automatically generate a URL to directly access the service. You can configure or modify the default web URL port either at any time.

This tutorial will explain the process of configuring the default port and accessing the service with the generated URL.

Adding a Default Web URL Port

Creating a Container With a Default Web URL Port

  1. Container Station
  2. On the menu, go to Containers.
  3. Click Create.

    The Create Container window opens.

  4. In the Image field, specify the name and version tag for an existing container.
    Note:

    You must separate the name and version with a colon (:).

  5. Click Next.
  6. Configure the container settings.

    Setting

    Action

    Name

    Specify a container name that contains 2 – 64 characters, starts with a letter or number, and only contains the following characters:

    • Valid characters:: A–Z, a–z, 0–9

    • Valid special characters:: Hyphen (-), Underscore (_), or Period (.)

    Default web URL port

    Enable this setting and specify a port number.

    This should be the container port and not the published host port. For example, entering 80 for an NGINX container or 8080 for a Jenkins container.

    Note:

    The default web URL port is only used for the first connected network in the list.
  7. Click Next.
  8. Review the container settings and then click Finish.

Container Station creates the container and saves the default web URL port. You can now use the web shortcut link, see Accessing Services with a Web Shortcut Link.
