Redfish Profile Simulator

About

Redfish Profile Simulator is a Python34 real simulator of the "simple monolithic server" feature profile.

• A simple, minimal Redfish Service
• For a monolithic Server
• Aligned with: OCP Remote Machine Management Spec feature set

Description

• Based on flask
• Initial resources are loaded from a catfish mockup into python dictionary structures
  • After that, data is read/patched... to the dictionaries
• Supports BasicAuth, as well as Redfish Session Auth (for one session, one user)
• Uses:
  • easy to add new URIs for testing a client
  • easy to tweak behavior or add bad responses to test a client
  • allows testing of authentication -- which current mockup servers dont do
  • easy to insert print statements in service to see if data coming across good..etc

Current Limitation:

• supports a single user/passwd and token
• the user/passwd is: root/password123456
• The authToken for Session Auth is: 123456SESSIONauthcode
• Supports only HTTP (not HTTPS)
• with redfishtool, use options: redfishtool.py -r127.0.0.1:5000 -u root -p password123456 -S Never

Usage

• python redfishProfileSimulatorMain.py [options]

• [Options]:

    -V,  --Version,--- the program version
    -h,  --help,   --- help
    -H<hostIP>,  --Host=<hostIp>   --- host IP address. dflt=127.0.0.1
    -P<port>,--Port=<port> --- the port to use. dflt=5000
    -p<profile_path>, --profile=<profile_path>   --- the path to the Redfish profile to use. dflt="SimpleOcpServerV1"
  

Implementation

• The simulation includes an http server, RestEngine, and dynamic Redfish datamodel.
• You can GET, PATCH,... to the service just like a real Redfish service.
• Both Basic and Redfish Session/Token authentication are supported
  • for a single user/passwd and token
  • the user/passwd is: root/password123456
  • The authToken for Session Auth is: 123456SESSIONauthcode
  • these can be changed by editing the redfishURSs.py file---will make dynamic later.
• The http service and Rest engine is built on Flask, and all code is Python 3.4+
• The data model resources are "initialized" from the SPMF "SimpleOcpServerV1" Mockup.
  • and stored as python dictionaries
  • then the dictionaries are updated with patches, posts, deletes.
• The program can be extended to support other mockup "profiles".
• By default, the simulation runs on localhost (127.0.0.1), on port 5000.
  • These can be changed with CLI options: -P -H | --port= --host=

Simple OCP Server V1 Mockup Description

• A Monolithic server:

  • One ComputerSystem
  • One Chassis
  • One Manager

• Provides basic management features aligned with OCP Remote Machine Management Spec 1.01:

  • Power-on/off/reset
  • Boot to PXE, HDD, BIOS setup (boot override)
  • 4 temp sensors per DCMI (CPU1, CPU2, Board, Inlet)
  • Simple Power Reading, and DCMI Power Limiting
  • Fan Monitoring w/ redundancy
  • Set asset tag and Indicator LED
  • Basic inventory (serial#, model, SKU, Vendor, BIOS ver…)
  • User Management
  • BMC management: get/set IP, version, enable/disable protocol

• What it does NOT have -- that the Redfish 1.0 model supports

  • No PSUs in model (RMM spec did not include PSUs)
  • No ProcessorInfo, MemoryInfo, StorageInfo, System-EthernetInterfaceInfo
  • No Tasks
  • JsonSchema and Registries collections left out (since that is optional)
  • No EventService--Remote Machine Management spec used basic PET alerts
  • Uses only the pre-defined privileges and roles

TO DO

Some limitations to be extended in current implementation

• Auth supports a single hard-coded username, password, and AuthToken, although the protocol is 100% compliant with respect to testing clients trying to authenticate
  • ex with basic auth, you have to use the hard coded user/password
  • ex with Session Auth, you just use the hard coded AuthToken
• adding and deleting users not implemented--has 3 or 4 users predefined
• accountService properties can be written, but failed logins, lockouts, etc is not implemented
• system log not implemented yet
