Upgrade from Previous Versions

Upgrading the Genvid SDK from one version to another may include some manual steps. This page includes any steps required to update to version 1.26.0 from the last version. If you’re upgrading an older version of the SDK, start with any special upgrade instructions for your version found here.

General Upgrade Instructions

Upgrade the Genvid SDK

To set up the new SDK locally:

  1. Install the new SDK.

  2. Run the Python script to install the Genvid Toolbox.

    py install-toolbox.py
  3. Run the Genvid Bastion script to update your bastion.

    genvid-bastion reinstall --reconfigure -b {mybastion} -uml

Update Your Broadcast Website

If you used code from the samples we provide in your own project, note that we recently enforced a best practice concerning service discovery using consul in those samples. You should check again the samples and update your project accordingly. We invite you to use the consul health api instead of the catalog api to fetch the url of your services, since it is more likely that the url will point to a healthy service.

Update Your Game

To update your game without applying new features, just replace the old genvid.dll from the previous SDK with the one from the new SDK. The old plugins and integration should work as-is, with the exception of the specific upgrade instructions below.


Always follow the full upgrade path for the Genvid SDK version you’re using. For example: If you’re upgrading from version 1.6.0 to 1.10.0, start by upgrading from 1.6.0 to 1.7.0 then continue with each version.

See the full list of upgrade instructions for your specific version.

Upgrade the Javascript API

You should also upgrade the Genvid JavaScript API on your website.

Update Your Cluster

We strongly recommend keeping your old clusters as-is and creating a new one for the update.

To create a new cloud-based cluster, follow the standard instructions:

  1. Set up a new wingame AMI that matches the new version.
  2. Create new clusters.

To create a new local cluster, follow the standard instructions listed in the Initialize a Local Cluster section.

Once you have replaced all your clusters, you can remove the old SDK repositories from the Modules Section page.

Updating an Existing Cluster


Updating your cluster can replace all your instances and even erase your current configuration. We recommend not updating a live cluster. If you do, carefully check the changes before applying the plan.

You can update the module used to build your cluster by clicking on Reimport Module in the module section of your cluster infrastructure, then select the module new version and import it. Finally, click apply in the Terraform section.


Some changes can take time to propagate to AWS. This is especially true for IAM roles and policies, which could then create some conflicts when recreated. Re-applying the Terraform plan should fix the problem.

Update Genvid SDK Samples

Along with your own project, make sure you update any of the Genvid SDK samples you’ve previously installed.

Upgrade from 1.25.0 to 1.26.0

Changes to the Cluster-UI Settings

In the Encode -> Stream section of the Cluster-UI settings, we removed the dedicated field Video ID. We replaced it with a single field for all streaming services (YouTube, Twitch) and change the label to match the selected streaming service.

Table 1 New Field Labels
Twitch Channel
YouTube Video ID


To set the Consul key that used to be genvid/encode/stream/videoid you have to change it to genvid/encode/stream/channel.

Terraform variable cidr replaced by subnet_cidr_block_size in the Terraform settings.

In the Terraform settings, we replaced the variable cidr with subnet_cidr_block_size. This change fixes a known issue causing subnet collisions when updating clusters. The subnet IPs are now set to and this variable controls the cidr size.

For example, if you set subnet_cidr_block_size to 27, the subnet IPs will start at Other subnet IPs will be distributed proportionally across all availability zones.

Terraform variables Stage and Namespace removed.

We removed the Terraform variables Stage and Namespace from all Terraform modules.

AWS and Azure tag Name renamed genvid:cluster-name.

Terraform modules now allow users to define their own custom tags. To prevent clashes between Genvid default tags and user defined tags, we updated Genvid tags with the prefix genvid:.

In AWS, this causes the column Name to be empty. As a workaround, either add a column for the tag genvid:cluster-name in the EC2 console.

From the AWS Management Console:

  1. Click EC2.
  2. Click Instances.
  3. Click the settings button (gear icon).
  4. Select the tags you want columns for.

See the AWS documentation for more information about managing tags.

In Azure, the resources are still all available under the same resource group.

This will impact existing clusters only if they are updated.

Renamed 2 metrics sent by gvencode.

We renamed 2 metrics sent by gvencode due to typos in their names.

  • compostionssent is now compositionsent.
  • compostionssentsize is now compositionsizesent.

We didn’t update the names in the SDK documentation, as they were already correct there.

AWS and Azure indexed resources are now 0-based instead of 1-based.

Previously, resources that had names or identification that contained a number were 1-based. This yielded names like server-1, game-1, etc.

Starting with the release of 1.26.0, we changed the index to be 0-based. Identifiers will now start at 0: server-0, game-0, etc.

Updating Terraform modules found in previous versions.

You may run into an error if you’re updating a bastion server created from an earlier installation of Terraform. This error occurs when reimporting the new version of the module and running plan apply.

on main.tf.json line 118, in variable:
118:     "bastionid": {

The root module input variable "bastionid" is not set, and has no default
value. Use a -var or -var-file command line argument to provide a value for
this variable.

To fix this issue:

  1. Add a global variable named bastionid.
  2. Set the value of bastionid to the name of the bastion server you’re updating.
  3. Run plan apply.
