live-infrastructure

Awakening Church uses CloudFlare and Microsoft Azure to host nginx-rtmp configured for H.264/AAC HLS streaming running in Docker on CoreOS. This repositiory creates that infrastructure using Terraform. You can use this configuration to start your own copy of our live video transcoding system.

We use this system for 4 hours a week. Costs are estimated at about $5 per week. However, since Microsoft offers $5,000 per year in Azure credits to non-profits, including churches, this costs us nothing to run. Thanks Microsoft!

Usage

Gather the required Azure credentials. Install Terraform. Configure the required Terraform variables:

• azure_region Azure region, e.g. West US 2
• azure_tenant_id Azure Tenant ID
• azure_client_id Azure Client ID
• azure_client_secret Azure Client secret
• azure_storage_prefix Unique name for Azure storage, e.g. livevideoadventure
• cf_email CloudFlare Email
• cf_token CloudFlare API Token
• cf_domain CloudFlare Domain, e.g. awakeningchurch.com
• cors_http_origin Corresponds to CORS_HTTP_ORIGIN setting in awakening-nginx-rtmp
• publish_secret Corresponds to PUBLISH_SECRET setting in awakening-nginx-rtmp
• ssh_key_file File containing the public SSH key for the launched CoreOS instance

Check the plan:

terraform plan

Apply to launch the infrastructure:

terraform apply

We use these resources for a few hours. Once the broadcast is complete, we simply destroy the resources:

terraform destroy -force

Modifying Container Linux configuration

To modify the Container Linux configuration file, container-linux.yaml, install the Container Linux conifiguration transpiler. On macOS:

brew install coreos-ct

Then transpile container-linux.yaml into ignition.yaml with the command:

make
