Create (if required), install the necessary prerequisites, and deploy a sample plumber application on a DigitalOcean virtual machine. This command is idempotent, so feel free to run it on a single server multiple times.
do_provision(droplet, unstable = FALSE, example = TRUE, ...)The DigitalOcean droplet that you want to provision (see analogsea::droplet()). If empty, a new DigitalOcean server will be created.
If FALSE, will install plumber from CRAN. If TRUE, will install the unstable version of plumber from GitHub.
If TRUE, will deploy an example API named hello to the server on port 8000.
Arguments passed into the analogsea::droplet_create() function.
Provisions a Ubuntu 16.04-x64 droplet with the following customizations:
A recent version of R installed
plumber installed globally in the system library
An example plumber API deployed at /var/plumber
A systemd definition for the above plumber API which will ensure that the plumber
API is started on machine boot and respawned if the R process ever crashes. On the
server you can use commands like systemctl restart plumber to manage your API, or
journalctl -u plumber to see the logs associated with your plumber process.
The `nginx`` web server installed to route web traffic from port 80 (HTTP) to your plumber process.
ufw installed as a firewall to restrict access on the server. By default it only
allows incoming traffic on port 22 (SSH) and port 80 (HTTP).
A 4GB swap file is created to ensure that machines with little RAM (the default) are able to get through the necessary R package compilations.
