Cloud resource keys

[minondoa]

Here are listed all the changes that we decided to make in the Meeting 2016-12-14

• in resources.conf change “cloud” to “cloud_provider” (ticket #6056)
• change the key “nodes” to “instances”, as in the number of instances (VMs) that will be created
• add a new value for the key “vm_communicartor” called “pk_ssh” (ticket #6051)
• we will consider changing the names for the keys “vm_communicator” to something that will reflect that it will be used for creating cloud resources
• remove the "fedcloud" value from the lrms
  • instead of "fedcloud", to encompass all of the clouds that use the rOCCI API, it's now going to be called "rocci", since the implementation would be the same

• add a new key called "cloud_connector" - depending on what protocol the cloud, the user chose, will be using the possible values will be:
  • “rocci”
  • “ec2” - “cloud_auth” is always “basic” (by default)

---

Depending on the cloud's protocol, some new keys will have to be added.

Values when using "rocci":

• “cloud_auth” - this will indicate what type of authentication the user will be using to access the cloud services. Its possible values will be:
  • “x509” - the user will use a x509 proxy certificate to identify himself
    • the user will have to run the command “drm4g id <resource_name>” init”
    • the user can specify the key “myproxy_server” if he knows what he's doing, but it won't be necessary since it's value will be set to “myproxy1.egee.cesnet.cz” by default
• “basic” - the user will use a previously created account to identify himself. In this case, two more keys will have to be specified:
  • “access_key” and “secret_key” (so the user must have an account with the provider he wishes to use)

Values when using "ec2":

• add a key called “billing” - to define what type of payment method you'll be using
  • “on-demand”
  • “on-spot”
  • “on-reserved”
    • we will try to get the information about the billing prices depending on what the user wants
• add a key called “region”
  • its values will be the same as the ones found in the ​Amazon Web Services web page
