== Setting up for OpenStack deployments
|
|
In this document we will explain how one could setup their laptop for AgnosticD deployment with OpenStack.
|
|
If you are a Red Hatter, you can use link:rhpds.redhat.com[rhpds.redhat.com] to request access to our OpenStack cluster.
|
. Log in to link:https://rhpds.opentlc.com[https://rhpds.redhat.com] using your opentlc user.
|
. Go to *Services* -> *Catalogs* -> *Events Development* -> *Summit DEV OSP Sandbox*.
|
. Click *Order* -> *Submit*
|
|
NOTE: You will receive three emails indicating the status of the environment and instructions for accessing the environment.
|
In the third email you receive all information you need to login to the client machine that would have the rest of required information.
|
|
NOTE: You can use the VM as your ansible host or copy the files over to your laptop and work locally.
|
|
|
=== Configure your environment for running OpenStack Ansible
|
|
. Please make sure the file `/etc/ansible/hosts` doesn't exist or is empty, otherwise this default inventory file will cause problems later.
|
. Install `virtualenv` and `pip3` (On your laptop or on the clientVM):
|
+
|
[source, shell]
|
----
|
# on Linux
|
$ sudo yum install python3-pip python-virtualenv -y
|
# on Mac
|
$ brew install python pyenv-virtualenv
|
----
|
|
. Create virtualenv environment and download python requirements:
|
.. Create virtualenv and activate
|
+
|
[source, shell]
|
----
|
$ virtualenv openstack-ansible-2.9
|
|
##In Mac
|
$ pyenv virtualenv openstack-ansible-2.9
|
|
|
## In Mac, if you find the error " the error: error: pyenv: pip: command not found]", it could because you need pip3, in that case please do:
|
$ alias pip=pip3
|
$ pip install --upgrade pip
|
|
$ source openstack-ansible-2.9/bin/activate
|
|
## In Mac
|
$ source /Users/[USER]/.pyenv/versions/openstack-ansible-2.9/bin/activate
|
|
## ^replace [USER] with your username or the proper path
|
|
----
|
.. Install the python modules inside that virtualenv
|
*** On Mac
|
+
|
[source,shell]
|
----
|
$ pip3 install -r https://raw.githubusercontent.com/redhat-cop/agnosticd/development/ansible/configs/ocp4-disconnected-osp-lab/files/macos_requirements.txt
|
----
|
*** On Linux with Python 2
|
+
|
[source,shell]
|
----
|
(openstack-ansible-2.9) $ pip install -r https://raw.githubusercontent.com/redhat-cop/agnosticd/development/tools/virtualenvs/openstack-ansible-2.9-python2.txt
|
----
|
*** On Linux with python 3:
|
+
|
[source,shell]
|
----
|
(openstack-ansible-2.9) $ pip install -r https://raw.githubusercontent.com/redhat-cop/agnosticd/development/tools/virtualenvs/openstack-ansible-2.9-python3.txt
|
----
|
*** Multi-platform, latest modules (should work for all with both python2 and python3)
|
+
|
[source,shell]
|
----
|
(openstack-ansible-2.9) $ pip install -r https://raw.githubusercontent.com/redhat-cop/agnosticd/development/tools/virtualenvs/openstack-ansible-latest.txt
|
----
|
|
=== Getting your OpenStack Credentials
|
|
. Create the `~/.config/openstack/clouds.yaml` file on your laptop using the information provided in the final email.
|
+
|
[source,bash]
|
----
|
$ mkdir -p ~/.config/openstack
|
$ vim ~/.config/openstack/clouds.yaml
|
----
|
|
. Review your `~/.config/openstack/clouds.yaml`:
|
+
|
[source,bash]
|
----
|
cat ~/.config/openstack/clouds.yaml
|
clouds:
|
35eb-project:
|
auth:
|
auth_url: "http://169.47.17.15:5000/v3"
|
username: "35eb-user"
|
project_name: "35eb-project"
|
project_id: "1a79cf800ff94754bb495e2c1fd9d433"
|
user_domain_name: "Default"
|
password: "YOUR_TEMP_PASSWORD"
|
region_name: "regionOne"
|
interface: "public"
|
identity_api_version: 3
|
----
|
|
. Check that your credentials are working:
|
+
|
[source,bash]
|
----
|
$ openstack --os-cloud=GUID-project server list
|
+--------------------------------------+-----------+--------+------------------------------------------------+-------+---------+
|
| ID | Name | Status | Networks | Image | Flavor |
|
+--------------------------------------+-----------+--------+------------------------------------------------+-------+---------+

|
+--------------------------------------+-----------+--------+------------------------------------------------+-------+---------+
|
----
|
|
. Try to login to OpenStack UI: link:http://horizon.red.osp.opentlc.com/dashboard/auth/login/[]. You must use the credentials from `.config/openstack/clouds.yaml` to login to the UI.
|
|
=== Setting up AgnosticD and your development environment
|
|
. Clone the AgnosticD repository:
|
+
|
[source,bash]
|
----
|
git clone https://github.com/redhat-cop/agnosticd
|
----
|
|
. Create your `secret.yml` file *oustide the repository*, and edit it using the correct credentials based on your `clouds.yml` file:
|
+
|
[source,bash]
|
----
|
cat << EOF >> ~/secret.yml
|

|
|
# Do not create PROJECT, we already have one and want to use it
|
|
osp_project_create: false
|
|
EOF
|
----
|
|
. *First checkpoint*, make sure this secret file is correct by running the test-empty-config.
|
+
|
[source,bash]
|
----
|
cd agnosticd/ansible
|
|
ansible-playbook main.yml \
|
-e @configs/test-empty-config/sample_vars_osp.yml \
|
-e @~/secret.yml
|
----
|
|
. Copy the `sample_vars.yml` file and call it `my_vars.yml`
|
+
|
[source,bash]
|
----
|
cp configs/just-some-nodes-example/sample_vars_osp.yml \
|
configs/just-some-nodes-example/my_vars.yml
|
----
|
|
. Edit the `my_vars.yml` and change the `guid` value to something short and unique.
|
+
|
WARNING: Do not pick the same GUID as the one you got for access to the OSP cluster.
|
|
. *Second checkpoint*, Run the ansible-playbook command to deploy just-some-nodes-example
|
+
|
[source,bash]
|
----
|
ansible-playbook main.yml \
|
-e @configs/just-some-nodes-example/my_vars.yml \
|
-e @~/secret.yml
|
----
|
+
|
NOTE: If you are having python2 Vs. Python3 issues, Add `/usr/bin/python3.6` before the ansible-playbook command. For example: `/usr/bin/python3.6 ansible-playbook ansible/main.yml -e @configs/just-some-nodes-example/my_vars.yml -e@~/secret.yml`
|
|
|
. Check that the VM was installed and ssh into the box using the created key
|
+
|
[source,bash]
|
----
|
openstack --os-cloud=35eb-project server list
|
ssh -i /tmp/output_dir/${GUID}_infra_ssh_key.pem cloud-user@169.47.183.41
|
----
|
|
. You can now adapt `my_vars.yml` to your needs. Create different kind of instances, more security groups, etc.
|
|
=== Clean up
|
|
. Destroy the deployment:
|
+
|
[source,bash]
|
----
|
ansible-playbook destroy.yml \
|
-e @configs/just-some-nodes-example/my_vars.yml \
|
-e @~/secret.yml
|
----
