#This repo should be moved to https://gerrit.akraino.org/r/admin/repos/nc/tf

Instructions for installing airship+tungstenfabric using the Regional Controller and the TF Blueprint

  1. The Regional Controller should already be running somewhere (hopefully on a machine or VM dedicated for this purpose). See here_ for instructions on how to start the regional controller.

    .. _here: https://wiki.akraino.org/display/AK/Starting+the+Regional+Controller

  2. Clone the tf repository using

    
      #git clone https://gerrit.akraino.org/r/tf.git
      git clone https://github.com/gleb108/akraino-tf.git
    
  3. Regional Controller goes to the remote node by ssh, so it needs ssh private key. It can be provided as http URL. (It's not secure for production, it's only OK for the demo) Put ssh private key and script deploy.sh on some web server. Ssh public key must be writen to the .ssh/authorized_keys on remote node. Hint: python provisional web server can be used on the localhost. Use python3 -m http.server

  4. Edit the file setup-env.sh.

    Update all the environment variables define the ip addresses nodes, web server baseurl, etc Define where the Regional Controller is located, as well as the login/password to use (the login/password shown here are the built-in values and do not need to be changed if you have not changed them on the Regional Controller):

    
      export RC_HOST=<IP or DNS name of Regional Controller>
      export USER=admin
      export PW=admin123
    
  5. Generate yaml files from templates

       source setup-env.sh
       cat objects.yaml.env | envsubst > objects.yaml
       cat TF_blueprint.yaml.env | envsubst > TF_blueprint.yaml  
    
  6. Clone the api-server repository. This provides the CLI tools used to interact with the Regional Controller. Add the scripts from this repository to your PATH:

      git clone https://gerrit.akraino.org/r/regional_controller/api-server
      export PATH=$PATH:$PWD/api-server/scripts
    
  7. Load the objects defined in objects.yaml into the Regional Controller using:

      rc_loaddata -H $RC_HOST -u $RC_USER -p $RC_PW -A objects.yaml
    
  8. Load the blueprint into the Regional Controller using:

      rc_cli -H $RC_HOST -u $RC_USER -p $RC_PW blueprint create TF_blueprint.yaml
    
  9. Get the UUIDs of the edgesite and the blueprint from the Regional Controller using:

      rc_cli -H $RC_HOST -u $RC_USER -p $RC_PW blueprint list
      rc_cli -H $RC_HOST -u $RC_USER -p $RC_PW edgesite list
    

    These are needed to create the POD. You will also see the UUID of the Blueprint displayed when you create the Blueprint in step 8 (it is at the tail end of the URL that is printed). Set and export them as the environment variables ESID and BPID.

      export ESID=<UUID of edgesite in the RC>
      export BPID=<UUID of blueprint in the RC>
    
  10. Generate POD.yaml

   cat POD.yaml.env | envsubst > POD.yaml
  1. Create the POD using:

       rc_cli -H $RC_HOST -u $RC_USER -p $RC_PW pod create POD.yaml
    

    This will cause the POD to be created, and the deploy.sh workflow script to be run on the Regional Controller's workflow engine. This in turn will login to remote node by ssh and install airship+ tungstenfabric demo on it

  2. If you want to monitor ongoing progess of the installation, you can issue periodic calls to monitor the POD with:

          rc_cli -H $RC_HOST -u $RC_USER -p $RC_PW pod show $PODID
    

    where $PODID is the UUID of the POD. This will show all the messages logged by the workflow, as well as the current status of the workflow. The status will be WORKFLOW while the workflow is running, and wil change to ACTIVE if the workflow completes succesfully, or FAILED, if the workflow fails.
