Login to DockerHub

To access our private DockerHub registry and Live Transcoder docker images, you must log in with your distinctive DockerHub access token.

Get the access token

You need to get your personal access token from the Customer Dashboard. It looks similar to this: dckr_pat_R6jqYHF9a7fMe37esO_aW8PfWfQ. Older tokens can look like this 4df2f492-6617-4b91-9301-9fbad09f43fd.

Login from host

On your host instance, run:

docker login --username comprimato

The username is comprimato. Once prompted, enter the DockerHub access token.

Get the docker-compose.yml

docker-compose.yml file contains instructions for Docker on how to run the Live Transcoder container. It also contains your license key so each license has its separate docker-compose.yml! You can download it from the Customer Dashboard.

On the Customer Dashboard, there is a WGET button that generates the wget terminal command that can download the docker-compose.yml to your host instance. Click on it to copy the command to the clipboard. If you can't see the button, please, scroll right while hovering above your license row; it's in the rightmost column.

Your wget command will look similar to this.

wget -O docker-compose.yml https://link-generated-for-you

Run it on the host instance to download your docker-compose.yml.

Alternatively, you can download it to your computer by clicking on the DOWNLOAD button and upload it to your host instance manually, e.g., using the scpcommand:

scp -i path/to/your-private-key.pem path/to/docker-compose.yml ec2-user@IP_ADDRESS:

Tip to distinguish between multiple Live Transcoder instances

If you plan to spawn multiple instances and would like to distinguish between them (e.g., names of NDI sources or in the Monitoring Dashboard), open the docker-compose.yml file and edit the hostname on the line hostname: transcoder0. Save the change and continue to the next step.

Optional: Alternative Way to Get the Docker Compose Template

To ensure there is no version mismatch in docker-compose.yml, you can extract the template directly from the Docker image metadata. Comprimato embeds the docker-compose information within a special image label in base64 format.

To retrieve it, run the following command:

docker inspect <image>:<tag> | jq -r ".[].Config.Labels.\"com.comprimato.docker.compose\"" | base64 -d

Important Notes:
After obtaining the docker-compose.yml template, be sure to update the following values before use:

1. Image with tag value – Ensure that the image field in the docker-compose.yml file reflects the correct <image>:<tag> you want to deploy.
2. TRC_LICENSE_KEY value – Set/copy your valid license key in the environment variables section of the docker-compose.yml file.

This method ensures that your docker-compose.yml is always aligned with the image version and properly configured for deployment.

Run the container!

Run the following command in the same directory as the docker-compose.yml file is located:

docker-compose up -d

Check that the Live Transcoder Docker container is running by a command:

docker ps

It should print output similar to this:

CONTAINER ID   IMAGE                               COMMAND        CREATED             STATUS         PORTS     NAMES
