Create and delete Google Load Balancer components.

Pros:

• The tool wraps gcloud commands. This helps those who are familiar with gcloud commands and are referencing google cloud docs.

Cons/Limitations:

• The tool assumes that the source of truth is the configuration. It does not detect and will update and overwrite any manual changes that does not match the configuration.
• This is notably different from terraform which will perform a diff calculation, which can provide a diff in the plan.
• The gcloud compute [RESOURCE] update will not run if there are no attributes in the command, else gcloud reports an error.

Commands:

glb plan APP
glb up APP
glb down APP
glb show APP

APP is your app name. IE: demo

• External Load Balancer (Global)
• Internal Load Balancer (Region)

The tool creates these resources:

• firewall rule
• health check
• backend service
• url map
• target http proxy
• forwarding rule

If SSL is enabled it'll also create a

• target https proxy (associated with the same url map)
• forwarding rule (associated with the target https proxy)

The same url map is used because that's what shows up as a Load Balancer in the Google console.

gem install glb
