Some tools to help use Google Cloud compute nodes.

Run sessionender as part of launching a new node that you intend to use interactively. It shuts the node down when the login tty has been idle for more than a configurable value (default is 15 minutes) to save money.
makecloudconfig assembles a single cloudconfig file for a GCP COS node out of a list of services. This makes it easy to pack a number of Docker containers into a single node. Presumably I could have used Kubernetes or docker compose or something similar to do this but this was easy, predictable and cheap.
gocloud tool to launch a GCP node without using gcloud. Smaller and faster than using gcloud but does so much less. How to use:
- make a configuration file in json format.
```
 {
 	"defaultzone": "your-preferred-zone",
 	"projectid": "your-gcp-project",
 	"instancetypes": {
 		"smallnodisk": {
 			"hardware": "e2-small",
 			"family": "your-favourite-image-family",
 			"userdatafile": "path-to-cloudconfig"
 		}
 	}
 }
```
- Make one:
```
 gocloud make smallnodisk myinstance
```
- I have some related tooling to provision the node. A bare node needs a useful cloudconfig file, a configured service account, etc.
- I use the mkconfig tool to setup a node from within the cloudconfig file.
- On MacOS, gocloud wants to read selected configuration that it will push to the GCP metadata service from the MacOS KeyChain. The gocloud show-meta subcommand will show if this is configured correctly.
