After you run terraform apply on this configuration, it will output the
floating IP address assigned to the exposed Docker node (which is the manager).
After your instance started, you can access the Swarm UI application on the
port 88. You will also get an IP address to a bastion which allows you to
connect using SSH.
First set the required environment variables for the OpenStack provider by sourcing the credentials file.
source openrc
Before starting this script, you need to generate an SSH key dedicated for this deployment:
ssh-keygen -f ~/.ssh/id_rsa.terraform
Afterwards run with a command like this:
terraform apply \
-var 'external_gateway=0229c96d-90e6-431f-bf44-563285a0e6d4'
Note: You will need to replace the external gateway id by your own network id used to get an external IP address. You may also need to change the "pool" variable to the name of this network.
