Redfish Ruby Client

This repository contains source code for redfish_client gem that can be used to connect to Redfish services.

Add this line to your application's Gemfile:

gem "redfish_client"

And then execute:

$ bundle

Or install it yourself as:

$ gem install redfish_client

Minimal program that uses this gem would look something like this:

require "redfish_client"

root = RedfishClient.new("https://localhost:8000",
                         prefix: "/redfish/v1",
                         verify: false)
puts root
root.login("username", "password")
puts root.Systems
root.logout

Redfish service can return a 202 status when we request an execution of a long-running operation (e.g. updating firmware). We are expected to poll the monitor for changes until the job terminates.

Responses in Redfish client have a built-in support for this, so polling the service is rather painless:

# Start the async action
response = update_service.Actions["#UpdateService.SimpleUpdate"].post(
  field: "target", payload: { ... },
)
# Wait for the termination
response = update_service.wait(response)
# Do something with response

It is also possible to manually poll the response like this:

response = update_service.Actions["#UpdateService.SimpleUpdate"].post(
  field: "target", payload: { ... },
)
until response.done?
  # wait a bit
  response = update_service.get(response.monitor)
end

Response is also safe to (de)serialize, which means that the process that started the async operation and the process that will wait for it can be separate:

response = update_service.Actions["#UpdateService.SimpleUpdate"].post(
  field: "target", payload: { ... },
)
send_response_somewhere(response.to_h)

# Somewhere else
response = Response.from_hash(receive_response_from_somewhere)

After checking out the repo, run bin/setup to install dependencies. Then, run bundle exec rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To create new release, increment the version number, commit the change, tag the commit and push tag to the GitHub. Travis CI will pick from there on and create new release, publishing it on https://rubygems.org.
