Galaxy live build configuration

Recommended images

The OS image has to be available in the Tenant. Laniakea has been tested using CentOS 7.

CMDB configuration

The image details must be uploaded on CMDB (see section CMDB and CPR). The json file needs the following details:

image_id: is the ID of the image on the cloud platform, e.g. Openstack.
service: is the service ID, configured on CMDB.
image_name: is the name of the image that has to be used in the tosca template in the image field.

SSH on CMDB virtual machine and create the file cmdb-data/centos.json with the following content:

{
  "type": "image",
  "data": {
      "image_id": "<centos-image-id>",
      "image_name": "centos-7-vmi",
      "architecture": "x86_64",
      "type": "linux",
      "distribution": "centos",
      "version": "7",
      "service": "<service-id>"
  }
}

where centos-image-id is the image ID on the Cloud platform, while service-id is the service ID on CMDB.

To upload the image information on CMDB:

curl -X POST http://cmdb:<cmdb_crud_password>@localhost:5984/indigo-cmdb-v2 -H "Content-Type: application/json" -d@cmdb-data/centos.json

The image shuld now be available on CMDB with the name: centos-7-vmi.

Tosca template configuration

`Galaxy`

The TOSCA template of the Galaxy live build is located at /opt/laniakea-dashboard-config/tosca-templates/galaxy.yaml and is configured to exploit CentOS 7 as default image:

galaxy_server:
...
    # Guest Operating System properties
    os:
      properties:
        image: centos-7-vmi
...

If the images is uploaded on CMDB with a different name, the image field needs to be changed accordingly.

`Galaxy (elastic) cluser`

The Galaxy cluster TOSCA template is /opt/laniakea-dashboard-config/tosca-templates/galaxy-cluster.yaml. The Galaxy elastic cluster TOSCA template is /opt/laniakea-dashboard-config/tosca-templates/galaxy-elastic-cluster.yaml.

The image configuration is the same. There are two image fields, one for the fronte node:

lrms_server:
...
    # Front-End Guest Operating System properties
    os:
      properties:
        image: centos-7-vmi
...

and one for the worker node:

lrms_wn:
...
    # Worker Node Guest Operating System properties
    os:
      properties:
        image: galaxy-base
        #image: centos-7-vmi
