Ubuntu 16.04, just installed the Hyperledger composer and all its prereqs. I created a PeerAdmin card, I started the Composer Playground locally.

Trying to follow this basic tutorial: https://hyperledger.github.io/composer/tutorials/playground-tutorial.html

Step2: Creating new business network I entered the name (tutorial-network), optional description, selected 'empty-business-network'. This is all the tutorial says that is required to Deploy this network, but my browser has the "Deploy" button grayed out.... not allowing me to deploy. I also tried entering Admin in the Network Admin Card Name. That didn't help. I couldn't figure out any other options below that would make the Deploy button clickable.

What am I missing?

Within Hyperledger Composer Playground there are 2 types of connections (e.g., hlfv1 and Web Browser). Each of those has "Deploy a new business network." Deploying a new business network from the hlfv1 connection section does not provide an enabled "Deploy" button. If you deploy a new business network from the Web Browser connection, the button is enabled.

Is your Fabric running? If is is not running, you will see the greyed out button.

You can run the command docker ps to see if your Development Fabric is running, and there should be 4 containers.

If you have restarted your machine it is likely the Fabric is not running. If you previously had no data on the Fabric, then you can just issue the startFabric.sh script frpom the fabricTools folder.
