Missing devops-dojo-net Docker network causes container creation failures

[alanops]

Problem

The server attempts to connect scenario containers to a Docker network named 'devops-dojo-net' which may not exist.

Current Behavior

• Server runs: docker run ... --network devops-dojo-net ...
• If the network doesn't exist, container creation fails with: "network devops-dojo-net not found"
• The network is only created when docker-compose is running

Expected Behavior

• The server should ensure the network exists before starting containers
• Or handle the error gracefully and create the network if needed

Root Cause

In src/server/index.ts:

const args = ['run', '-it', '--rm', '--name', containerName, '--network', 'devops-dojo-net', imageName];

The network is defined in docker-compose.yml but the server doesn't verify its existence.

Solution

Options:

1. Create the network on server startup if it doesn't exist
2. Remove the network requirement and use default bridge
3. Add error handling to create network on-demand

Impact

• Scenarios fail to start if docker-compose hasn't been run
• Poor user experience with cryptic error messages
