This quickstart guide will help you get Blazer up and running with Container Apps on Crunchy Bridge. We recommend you start with the Container Apps Quickstart to get a general understanding of Container Apps.
Additional documentation for the Blazer Docker image can be found on the Blazer Docker GitHub page.

Blazer with Container Apps Quickstart
First ensure you have Container Apps enabled with
CREATE EXTENSION pgpodman;.
Next, find your cluster’s database URL to include as the
DATABASE_URL parameter when you run the container. You can find the URL in the Connection section of the cluster dashboard (choose the
application role), or by running
cb uri --role application <cluster name> on the command line.
Initialize the tables used by Blazer using your own value for
SELECT run_container('-dt -e DATABASE_URL="your-database-URL" docker.io/ankane/blazer rails db:migrate');
The initialization will run and its container will exit.
To start your Blazer app, run the following using your own value for
SELECT run_container('-dt -p 5433:8080/tcp -e DATABASE_URL="your-database-URL" docker.io/ankane/blazer');
Now you can visit your running Blazer app at your-host-URL:5433. You can find your Host URL in the Overview section of your cluster dashboard, or by running
cb info <cluster name>.
Configuring simple authentication for Blazer
By default, the above setup will create a public app that anyone who knows the URL can access. It is recommended that you setup authentication. You can set up basic authentication by setting the
BLAZER_PASSWORD values when you initiate the Container App:
SELECT run_container('-dt -p 5433:8080/tcp -e DATABASE_URL="your-database-URL" -e BLAZER_USERNAME="desired-username" -e BLAZER_PASSWORD="desired-password" docker.io/ankane/blazer');
