Deploying a Marketplace App

The Linode Marketplace allows you to easily deploy software on a Compute Instance using the Cloud Manager. See Get Started with Marketplace Apps for complete steps.

  1. Log in to the Cloud Manager and select the Marketplace link from the left navigation menu. This displays the Linode Create page with the Marketplace tab pre-selected.

  2. Under the Select App section, select the app you would like to deploy.

  3. Complete the form by following the steps and advice within the Creating a Compute Instance guide. Depending on the Marketplace App you selected, there may be additional configuration options available. See the Configuration Options section below for compatible distributions, recommended plans, and any additional configuration options available for this Marketplace App.

  4. Click the Create Linode button. Once the Compute Instance has been provisioned and has fully powered on, wait for the software installation to complete. If the instance is powered off or restarted before this time, the software installation will likely fail.

To verify that the app has been fully installed, see Get Started with Marketplace Apps > Verify Installation. Once installed, follow the instructions within the Getting Started After Deployment section to access the application and start using it.

Note
Estimated deployment time: MainConcept Plugins for FFmpeg should be fully installed within 5-10 minutes after the Compute Instance has finished provisioning.

Configuration Options

  • Supported distributions: Debian 11
  • Recommended plan: At minimum, we recommend a 16GB Shared CPU Compute Instance for MainConcept Plugins for FFmpeg.

MainConcept Plugins for FFmpeg Options

Limited Sudo User

You can fill out the following fields to automatically create a limited sudo user for your new Compute Instance. This account will be assigned to the sudo group, which provides elevated permissions when running commands with the sudo prefix.

  • Limited sudo user: Enter your preferred username for the limited user. No Capital Letters, Spaces, or Special Characters
  • SSH public key for the limited user: If you wish to login as the limited user through public key authentication (without entering a password), enter your public key here. See Creating an SSH Key Pair and Configuring Public Key Authentication on a Server for instructions on generating a key pair.
  • Disable root access over SSH: To block the root user from logging in over SSH, select Yes (recommended). You can still switch to the root user once logged in, and you can also log in as root through Lish.
Locating Your Sudo Password As Root
If you disable root access for your deployment and do not enter a valid SSH public key, you will need to login as the root user via the Lish console and locate the credentials file found at /root/.credentials to obtain the limited sudo user password.

Getting Started after Deployment

Logging In

Once all packages have finished installing, you can login to your instance to access MainConcept’s FFmpeg installation and plugins.

  1. Using the limited sudo user you created during deployment, login to your instance via SSH. Replace LIMITED_USER with your sudo user and 192.0.2.1 with the address of your Compute Instance:
    ssh LIMITED_USER@192.0.2.1
  2. Navigate to the mainconcept directory and view the installed packages:
    cd /opt/mainconcept/
    ls
  3. You should see the following:
    ffmpeg-omx  omx  sdk
