Installing Pulp 3 and getting all the services running can be challenging. To reduce the complexity of getting started with Pulp, the Pulp team created a single container image that has all necessary services to run Pulp 3.

The image is available under the pulp namespace on Dockerhub. This image includes the Ansible, Container, File, Maven, and RPM plugins. A new version is published every time there is a plugin update available. You can update your environment to the latest version of the container using docker pull.

If you experience any problems, check the Known Issues section for workarounds. If you have any questions, feel free to reach out to us on pulp-list@redhat.com or the #pulp channel on Freenode IRC.

You can use either podman or docker. If you use docker, substitute docker for podman in the following examples.

The following commands can be used to start Pulp 3.4.1 with podman 1.8.0, which is available on Fedora 31.

$ mkdir settings pulp_storage pgsql containers
$ echo "CONTENT_ORIGIN='http://$(hostname):8080'
ANSIBLE_API_HOSTNAME='http://$(hostname):8080'
ANSIBLE_CONTENT_HOSTNAME='http://$(hostname):8080/pulp/content'
TOKEN_AUTH_DISABLED=True" >> settings/settings.py

With SELinux

For systems with SELinux in enforcing mode, use the following command to start Pulp:

$ podman run --detach \
             --publish 8080:80 \
             --name pulp \
             --volume ./settings:/etc/pulp:Z \
             --volume ./pulp_storage:/var/lib/pulp:Z \
             --volume ./pgsql:/var/lib/pgsql:Z \
             --volume ./containers:/var/lib/containers:Z \
             --device /dev/fuse \
             pulp/pulp-fedora31

Without SELinux

For systems without SELinux in enforcing mode, use the following command to start Pulp:

$ podman run --detach \
             --publish 8080:80 \
             --name pulp \
             --volume ./settings:/etc/pulp \
             --volume ./pulp_storage:/var/lib/pulp \
             --volume ./pgsql:/var/lib/pgsql \
             --volume ./containers:/var/lib/containers \
             --device /dev/fuse \
             pulp/pulp-fedora31

In both cases, you will see the following output. The last line contains the container ID that you can use to execute commands inside the container.

Note that the container ID is unique to your deployment.

Use the container ID to reset the admin user’s password. podman also accepts the first part of the ID for convenience.

$ podman exec -it pulp bash -c 'pulpcore-manager reset-admin-password'
Please enter new password for user "admin":
Please enter new password for user "admin" again:
Successfully set password for "admin" user.

At this point, both the REST API and the content app are available on your host’s port 8080.

To start working with Pulp, check out the Workflows and Use Cases. For individual plugin documentation, see Pulp 3 Content Plugin Documentation.

Known Issues

Any known issues and workarounds are listed here.

Docker on CentOS 7

While using the version of Docker that is provided with CentOS 7, there is a known issue that will cause the following error to occur:

FATAL: could not create lock file "/var/run/postgresql/.s.PGSQL.5432.lock": No such file or directory

The version of Docker that is provided with CentOS 7 mounts tmpfs on /run. The Pulp Container recipe uses /var/run, which is a symlink to /run, and expects its contents to be available at container run time. This lack of availability causes the quick fail.

You can work around this by specifying an additional /run volume, which suppresses this behavior of the Docker run time. Docker will copy the image’s contents to that volume and the container will start as expected.
