h2. Katello Dev box with pulp3:

Dev boxes are deployed with pulp3 by default, via an rpm installation

* vagrant up katello-dev-box

* vagrant ssh katello-dev-box

h2. Katello Dev box with pulp3 on master:

Dev boxes come installed and configured to use yum, docker and files on pulp3. 

To enable ansible collection content type, you need to perform the following steps on the devel box:

#  <pre>

#  sudo pip3 install pulp-ansible==0.7.0

#  sudo mv /usr/local/lib/python3.6/site-packages/pulp_ansibl* /usr/lib/python3.6/site-packages/

#  sudo -u pulp PULP_SETTINGS='/etc/pulp/settings.py' DJANGO_SETTINGS_MODULE='pulpcore.app.settings' python3-django-admin migrate --no-input

#  </pre>

#  In file ~/foreman/config/settings.plugins.d/katello.yaml, 

#  Add :ansible_collection: true to the dict of content types.

#  Restart foreman server and refresh smart proxy features.

h2. Updating to a New Pulp Version in master & nightly:

1.  Request build of new version from build team unless its already built: http://yum.theforeman.org/pulpcore/  (https://github.com/theforeman/pulpcore-packaging)

2.  Install new version locally on top of existing version with a pip3 install command, or use rpms if they are built

3.  Identify any installer changes, open installer PRs

4.  Identify katello updates:

* Updating pulp client gem bindings in katello.gemspec 

* re-record vcr cassettes

* Identify any katello code changes needed to fix test cases

* open katello PR with changes

5. Update katello-repos in https://github.com/theforeman/foreman-packaging to point to the new version

6. Update forklift to deploy with the new version: https://github.com/theforeman/forklift/blob/master/vagrant/config/versions.yaml

5. Update client binding rpms at foreman-packaging

h2. Installing on a smart proxy:  The old (ansible-based) way to deploy pulp3:

* vagrant up centos7-proxy-devel

* Install the following packages in your dev box: 

* checkout this forklift pr: https://github.com/theforeman/forklift/pull/980

* setup ansible-pulp:

<pre>

cd forklift

git clone https://github.com/pulp/ansible-pulp.git

cd ansible-pulp

ansible-galaxy install -r requirements.yml -p ./roles

ansible-galaxy install pulp.pulp_rpm_prerequisites -p ./roles

</pre>

* within forkflift run:

<pre>

ansible-playbook ./playbooks/katello_pulp3.yml -l centos7-katello-devel

</pre>

* if this fails, run on the capsule:

<pre>

rm -rf /usr/lib/python3.6/site-packages/setuptools* -rf

</pre>

 and re-run:

<pre>

ansible-playbook ./playbooks/katello_pulp3.yml -l centos7-katello-devel

</pre>

* Refresh the smart proxy: 

  1. login to katello/foreman

  2. navigate to infrastructure > smart proxies

  3. click 'refresh' in the list of actions beside your smart proxy

You're now rockin' Pulp3

*To revert to pulp2 on smart proxy:*

vi /etc/foreman-proxy/settings.d/pulpcore.yml 

set enabled to false

sudo systemctl restart foreman-proxy

Refresh features of proxy

h2. Reset the Katello Pulp 3 Dev Environment

From within the Foreman directory this will take care of it:

<pre>bundle exec rake katello:reset</pre>

To ONLY reset the pulp3 db (if you know what your doing):

<pre>

sudo systemctl stop pulpcore*

sudo su - postgres

dropdb pulp -p 7878

createdb pulp -p 7878

exit

cd /usr/local/lib/pulp/src/pulpcore/

sudo -u pulp PULP_SETTINGS='/etc/pulp/settings.py' DJANGO_SETTINGS_MODULE='pulpcore.app.settings' /usr/local/lib/pulp/bin/django-admin migrate --no-input

sudo -u pulp PULP_SETTINGS='/etc/pulp/settings.py' DJANGO_SETTINGS_MODULE='pulpcore.app.settings' /usr/local/lib/pulp/bin/django-admin reset-admin-password --password password

Copy /etc/httpd/conf.d/05-foreman-ssl.d/pulpcore.conf  from your dev box to proxy

sudo systemctl restart pulpcore*

</pre>

h2. Example for querying the Pulp 3 API in a development environment:

<pre>

curl https://`hostname`/pulp/api/v3/status/   --cert /etc/pki/katello/certs/pulp-client.crt  --key /etc/pki/katello/private/pulp-client.key

</pre>

Recommendation: try the pulp-cli: https://github.com/pulp/pulp-cli#katello
