nebula-packet-global-deployment-example

A simple example that runs a Nebula manager with workers spread out across the world, the terraform output will return the manger_ip which you can connect to on port 80 with the username nebula and password nebula & a list of all workers which by default will run the example app on port 81.

Running instructions

1. clone the repo
2. cd into the repo folder
3. Change the run.tf (in repo root folder) to your variables
4. run terraform apply.

You now have a nebula cluster that includes a single manager and as many workers you gave it (default 9) spread out across packet regions (default 9 regions).

Requires:

• terraform 0.12.0 or higher
• PACKET_AUTH_TOKEN envvar set to your packet token
• a packet organization
• curl installed on the machine running terraform

Configuration variables :

• server_size - the size of the Nebula manager server - defaults to c1.small.x86
• server_region_device - the region where the nebula manager server will reside - defaults to ams1
• worker_count - the number of Nebula workers to create - defaults to 5
• worker_region_device - the regions where the workers will be deployed on - defaults to ["ams1","dfw2","ewr1","nrt1","sjc1"]
• worker_size - the size of the servers used in Nebula - note that at least 1GB is needed as it uses a RancherOS for simplicity sake - defaults to c1.small.x86
• PACKET_AUTH_TOKEN - the token used to connect to your packet account - needs to be declared as an envvar - required

Should you want to ssh to the devices for any reason (not needed for the system to work) you can do so with the private key & the root user for the manager and rancher user for the workers.

this can take 10-15 minutes for the manager to start as it has to install docker & docker-compose then download and run all containers, the initial boot of the workers is considerably faster but it might still be a couple of minutes after the terraform run completes.
