Quick Introduction

This quick cast shows how easy it is to install, bootstrap, and deploy a scale test environment.

Hello World

Let's create a virtual env on your local machine to bootstrap the installation, once installed you can move to the server node and call all your tasks from there

$ python3 -m venv --system-site-packages ~/directord
$ ~/directord/bin/pip install --upgrade pip setuptools wheel
$ ~/directord/bin/pip install directord

We need to create a catalog for bootstrapping. Let's assume we are installing directord in two machines:

  • directord-1 192.168.1.100 : directord server, a client

  • directord-2 192.168.1.101 : Only a client

For that we create a file

$ vi ~/directord-catalog.yaml

with the contents

directord_server:
  targets:
  - host: 192.168.1.100
  port: 22
  username: fedora

directord_clients:
  args:
    port: 22
    username: fedora
  targets:
  - host: 192.168.1.100
  - host: 192.168.1.101

We can now call directord to bootstrap the installation. Bootstrapping uses ssh to connect to the machines but after that ssh is no longer used. and you only need the ssh keys to connect your local machine to the machines you are installing into the server and client do not need shared keys between themselves.

To kickstart the bootstrapping you call directord with the catalog file you created and a catalog with the jobs required to bootstrap them.

$ ~/directord/bin/directord bootstrap \
                            --catalog ~/directord-catalog.yaml  \
                            --catalog ~/directord/share/directord/tools/directord-dev-bootstrap-zmq.yaml

Once that is ran you can now ssh to the server and issue all the commands from there

$ ssh fedora@192.168.1.100

First to make sure all the nodes are connected

$ sudo /opt/directord/bin/directord manage --list-nodes

Should show you

ID             EXPIRY  VERSION    HOST_UPTIME     AGENT_UPTIME
-----------  --------  ---------  --------------  --------------
directord-1    132.2   0.9.0      1:38:53.240000  0:00:00.051849
directord-2    131.69  0.9.0      1:39:25.780000  0:00:00.099533

Then we create our first orchestration job lets add a file called

$ vi helloworld.yaml

With the contents

- jobs:
  - ECHO: hello world

Then we call the orchestration to use it

$ sudo /opt/directord/bin/directord orchestrate helloworld.yaml

Should return something like:

Job received. Task ID: 9bcf31cb-7faf-4367-bf37-57c11b3f81dc

We use that task ID to probe how the job went or we can list all the jobs with"

$ sudo /opt/directord/bin/directord manage --list-jobs

That returns something like:

ID                                    PARENT_JOB_ID                           EXECUTION_TIME    SUCCESS    FAILED
------------------------------------  ------------------------------------  ----------------  ---------  --------
9bcf31cb-7faf-4367-bf37-57c11b3f81dc  9bcf31cb-7faf-4367-bf37-57c11b3f81dc              0.02          2         0

With the task id we can see how the job went:

$ sudo /opt/directord/bin/directord manage --job-info 9bcf31cb-7faf-4367-bf37-57c11b3f81dc

And voila here is our first orchestrated hello world:

KEY                   VALUE
--------------------  -------------------------------------------------------
ID                    9bcf31cb-7faf-4367-bf37-57c11b3f81dc
INFO                  test1 = hello world
                      test2 = hello world
STDOUT                test1 = hello world
                      test2 = hello world
