Flow of Operation using CLI commands

The equivalent of the previous section, using the CLI command rc_cli would be:

Enumerate the Machines


Assuming the machines to deploy on have not yet been made known to the RC, you would need to use the Node API to add them to the RC database.

Do this with the following API call, once per node:

Code Block
languagebash
themeRDark
$ cat > node.yaml <<EOF
name: nodename
description: a description of the node
hardware: <hardware profile UUID>
EOF
$ rc_cli -u admin -p abc123 node create node.yaml


Keep track of the UUID of each node that is returned from the API.

Create an Edge Site


Once the nodes are defined, you need to create an Edge Site (a cluster of nodes). Do this:

Code Block
languagebash
themeRDark
$ cat > es.yaml <<EOF
name: edgesitename
description: a description of the Edgesite
nodes: [ <list of node UUIDs> ]
regions: [ <list of region UUIDs> ]
EOF
$ rc_cli -u admin -p abc123 edgesite create es.yaml


Create/Verify the Blueprint


To get the UUID of the Blueprint, you would need to see which Blueprints are installed:

Code Block
languagebash
themeRDark
$ rc_cli -u admin -p abc123 blueprint list


If the Blueprint you want is missing, you may need to create it:

Code Block
languagebash
themeRDark
$ cat > blueprint.yaml <<EOF
blueprint: 1.0.0
name: my new blueprint
version: 1.0.0
description: description of the blueprint
yaml: ....
EOF
$ rc_cli -u admin -p abc123 blueprint create blueprint.yaml

...


Start the Deployment (Create the POD)

Start the deployment by creating a POD:

Code Block
languagebash
themeRDark
$ cat > pod.yaml <<EOF
name: my new POD
description: description of this POD
blueprint: 827cfe84-2e28-11e9-bb34-0017f20dbff8
edgesite: 2d3533e4-3dcb-11e9-9533-87ac04f6a7e6
EOF
$ rc_cli -u admin -p abc123 pod create pod.yaml



Make note of the UUID that is returned. You will need it to monitor the deployment.

Monitor the deployment by displaying the newly created POD. Note: the rc_cli command does not presently interface to the POD event API, so this will not be precisely equivalent to the curl calls shown above. This will return a list of events related to the POD similar to:

Code Block
languagebash
themeRDark
$ ./rc_cli -H rc -p admin123 pod show d72e1901-b9b3-4137-b217-fc3cae4575ac
