Katello Dev box with pulp3:¶

• vagrant up katello-dev-box
• vagrant ssh katello-dev-box

Adding the yum plugin:

sudo yum install -y gcc make cmake bzip2-devel expat-devel file-devel glib2-devel libcurl-devel libmodulemd2-devel ninja-build libxml2-devel python36-devel python36-gobject rpm-devel openssl-devel sqlite-devel xz-devel zchunk-devel zlib-devel swig3
sudo pip3 install scikit-build nose
sudo pip3 install pulp-rpm==3.0.0
cd /usr/lib/python3.6/site-packages/pulpcore
sudo -u pulp PULP_SETTINGS='/etc/pulp/settings.py' DJANGO_SETTINGS_MODULE='pulpcore.app.settings' python3-django-admin migrate --no-input
sudo systemctl restart pulpcore-resource-manager pulpcore-content pulpcore-api pulpcore-worker@1 pulpcore-worker@2

Adding the certguard plugin:

sudo pip3 install pulp_certguard
sudo pip3 install python-dateutil
sudo pip3 install rhsm
sudo systemctl restart pulpcore*

• 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

• Enable Katello Applicability
1. Add the following to ~/foreman/config/settings.plugins.d/katello.yaml:

:katello_applicability: true

You should now see file, docker and yum as supported content type under pulpcore in the Services tab

Katello Dev box with pulp3 on master:¶

On a devel box provisioned with steps above, run :

sudo pip3 install scikit-build nose
sudo yum install -y gcc make cmake bzip2-devel expat-devel file-devel glib2-devel libcurl-devel libmodulemd2-devel ninja-build libxml2-devel python36-devel python36-gobject rpm-devel openssl-devel sqlite-devel xz-devel zchunk-devel zlib-devel swig3

sudo pip3 install "git+https://github.com/pulp/pulpcore.git" \
  "git+https://github.com/pulp/pulp_file.git" \
  "git+https://github.com/pulp/pulp_rpm.git" \
  "git+https://github.com/pulp/pulp_container.git" \
  "git+https://github.com/pulp/pulp-2to3-migration.git" 

cd /tmp
sudo -u pulp PULP_SETTINGS='/etc/pulp/settings.py'  /usr/local/bin/pulpcore-manager migrate

cd ~/foreman
bundle exec rails katello:reset

Add the following to your /etc/pulp/settings.py

AUTHENTICATION_BACKENDS = ['pulpcore.app.authentication.PulpNoCreateRemoteUserBackend']

REST_FRAMEWORK__DEFAULT_AUTHENTICATION_CLASSES = (
    'rest_framework.authentication.SessionAuthentication',
    'pulpcore.app.authentication.PulpRemoteUserAuthentication'
)

Updating to a New Pulp Version in master & nightly:¶

1. Install new version locally ontop of existing version with a pip3 install command
2. Identify any installer changes, open installer PRs
3. 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

4. Update client binding rpms at foreman-packaging
5. Request rpm builds email satellite6-build@redhat.com or open a pr ourselves: https://github.com/evgeni/pulpcore-packaging#build

Old (ansible-based) way to deploy pulp3:¶

• Install a katello dev environment with forklift
• Install the following packages in your dev box:
  

  sudo yum -y install https://people.redhat.com/iballou/libcomps-0.1.12-1.git.0.937a666.el7.x86_64.rpm

  
  

  sudo yum -y install https://people.redhat.com/iballou/python3-libcomps-0.1.12-1.git.0.937a666.el7.x86_64.rpm

• checkout this forklift pr if its not merged: https://github.com/theforeman/forklift/pull/980
• setup ansible-pulp:
  

  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
  

• within forkflift run:
  

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

• 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

• Known Issue: Can't seem to use pulp3 on the box since pulp-api.service fails to start.
  

  sudo chmod -R 777 /etc/pki/pulp/
  sudo systemctl restart pulpcore-api.service
  

• Reset the Katello Pulp 3 Dev Environment
  From within the Foreman directory:
  

  bundle exec rake katello:reset

Smart Proxy Setup:¶

• Install a smart proxy to point to your pulp3_dev box
• ssh into the smart proxy
• sudo mkdir /etc/httpd/conf.d/05-foreman-ssl.d
• sudo vi /etc/httpd/conf/httpd.conf
• Add IncludeOptional "/etc/httpd/conf.d/05-foreman-ssl.d/*.conf to the end of the file and save
• In forklift > Run ansible-playbook ./playbooks/katello_pulp3.yml -l centos7-proxy-devel

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

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