Using Pulp 3 - Simpler and Faster

--- title: Using Pulp 3 - Simpler and Faster tags: Pulp, pulp-cli description: With the release of Pulp 3 in Dec 2019, Pulp underwent a complete technical overhaul. Pulp 3 has increased reliability and flexibility compared to earlier versions of Pulp. Over the last few months, there's been great focus on creating a Pulp 3 CLI. In this talk, Brian Bouterse will highlight Pulp 3 featureset through the brand new Pulp 3 CLI. --- ### Using Pulp 3 - Simpler and Faster Brian Bouterse Senior Principal Software Engineer bmbouter@redhat.com slides: https://hackmd.io/@pulp/rJx0Ymdud --- ## Agenda * What is Pulp? * What's new with Pulp3 * Basic Terminology * Show me the demos! * container * python * ansible * rpm --- ## What is Pulp? * Sync packages from public repositories * Organize and Share Packages * Approve and promote packages * Upload and distribute your own private packages --- ### Usage flow ![](https://pulp.plan.io/attachments/download/537381/pulp-overview.svg) --- ### What is Supported? ![](https://pulp.plan.io/attachments/download/537402/pulp_content_type_logos.png) --- ## New with Pulp3 3.0.0 released Dec 11, 2019 latest: 3.12.2 -- Apr 30, 2021 --- ### Improved Performance and Data Integrity Pulp 3 moves from MongoDB to PostgreSQL. :heart_eyes: :100: --- ### Faster Performance :clock230: On testing, synchronizing in Pulp 3 ranges from 2x to 8x faster than Pulp 2. --- ### Versioned Repositories :back: New ability to rollback safely to earlier versions. --- ### Disk Storage and Speed Solutions Select from multiple synchronization options for all content types to suit specific environmental requirements. --- ### Storage Options Can store data locally, or in the cloud with storage services like S3 and Azure. :cloud: --- ### Simplified Installation * Use the Ansible based installer * https://pulp-installer.readthedocs.io/en/latest/ * Or use pre-built containers * https://pulpproject.org/pulp-in-one-container/ * Or use the operator for k8s * https://github.com/pulp/pulp-operator --- ### Client bindings Make Pulp’s API language agnostic, requiring no customization. --- ### Better docs Browseable, auto-documented, OpenAPI. --- ### Better packaging Python’s PyPI replaces RPMs as the main packaging method, which allows for easy installation across Linux distributions. --- ### Plugin API Improvements to the Plugin API ensures compatibility with Pulp core and has led to an increasing list of Plugins. --- ## Migrating to Pulp3 * Use this migration plugin! * https://pulp-2to3-migration.readthedocs.io/en/latest/ Can migrate: docker, rpm, debian, and ISO content --- ## What is a Repository * A versioned set of packages/gems/containers/, aka content * These are typed, e.g. RPM, python, etc --- ## What is a Remote * Details about how to fetch content from other servers * These are typed --- ## What is a Distribution * Exposes a RepositoryVersion at a base path * e.g. 'mypath' at http://localhost:8080/pulp/content/ --- ## What is a Publication? * Creates metadata for a set of content * RPM, Python need this * Container and Ansible don't --- ## Today's Demo * Using the single container * https://pulpproject.org/pulp-in-one-container/ * With the pulp-cli * https://github.com/pulp/pulp-cli --- ### Pulling down the container `podman pull pulp/pulp` Or a specific version: `podman pull pulp/pulp` --- ### Create settings files ``` mkdir pulp cd pulp 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 ``` --- ### Start the container with SELinux * Running on port 8080 * http only (currently) * Usable with either `podman` or `docker` commands ``` 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 ``` --- ### Start the container *without* SELinux ``` 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 ``` --- ### Assign an admin password `podman exec -it pulp bash -c 'pulpcore-manager reset-admin-password'` --- ### Installing pulp-cli `pip install pulp-cli` https://github.com/pulp/pulp-cli --- ### Point pulp-cli at your container `pulp config create` `pulp config edit` 1. Point to "http://localhost:8080" 2. Add username, password --- ### Showing Container logs: `podman logs -f pulp` --- ### Status check `pulp status` --- ### Tasking Things * `pulp task list --state=running` * `pulp task list --state=failed` * `pulp task cancel --href /pulp/api/v3/tasks/15b8608b-724a-4182-acc3-bb5eb13a8b18/` --- ### Clean up orphans `pulp orphans delete` --- ### Interactive shell `pulp shell` --- ### CLI Niceties * Autocompletion * --help` on all commands --- ### API Documentation API Documentation: http://localhost:8080/pulp/api/v3/docs/ --- ### Container Overview Pulp3 is a registry supporting any client that adheres v2 regitry API: * `docker`/`podman` * `push`, `pull`, `tag` features * https://docs.pulpproject.org/pulp_container/ --- ### Container Demo * Showing off with http, but https fully supported * Showing off without RBAC, but RBAC fully supported --- ### Allow podman to use insecure Add snippet to `/etc/containers/registries.conf` ``` [[registry]] location = "localhost:8080" insecure = true ``` --- ### Login `podman login localhost:8080 --tls-verify=false` --- ### Tag an Image `podman tag pulp localhost:8080/asdf/pulp:latest` --- ### Push an Image `podman push localhost:8080/asdf/pulp:latest` --- ### Pull an Image `podman pull localhost:8080/asdf/pulp:latest` --- ### Pull Through Caching podman <-> pulp <-> docker/quay --- ### Listing Pushes `pulp container repository --type push list` --- ### Listing Distibutions `pulp container distribution list` --- ### Python Overview * Able to sync from PyPI * `pip` compatible, `twine` compatible (soon) * Integration with Bandersnatch * https://pulp-python.readthedocs.io/ --- ### Python Demo * Create a repository * Create a remote * Sync from PyPI --- ### Create a Repository `pulp python repository create --name pypi` --- ### PyPI mirroring `pulp python remote create --name full-pypi --url https://pypi.org/` --- ### Sync Specific Packages `pulp python remote create --name allowed-pypi --url https://pypi.org/ --includes '["shelf-reader", "numpy"]'` --- ### Use Package Filters `pulp python remote update --name allowed-pypi --package-types '["bdist_wheel"]' --prereleases False` --- ### List Remotes `pulp python remote list` --- ### Sync! `pulp python repository sync --name pypi --remote allowed-pypi` --- ### Create Publication `pulp python publication create --repository pypi` --- ### Publish Automatically `pulp python repository update --name pypi --autopublish` --- ### Go live `pulp python distribution create --name my-pypi --base-path my-pypi --publication <HREF>` --- ### Install with Pip `pip install -i http://localhost:8080/pulp/content/my-pypi/simple/ numpy` --- ### Have pip always use Pulp Edit `pip.conf` ``` cat <<EOT >> $VIRTUAL_ENV/pip.conf [global] index-url = http://localhost:8080/pulp/content/my-pypi/simple/ EOT ``` `pip install shelf-reader` --- ### Ansible Overview * Sync's content from: * galaxy.ansible.com * cloud.redhat.com * https://docs.pulpproject.org/pulp_ansible/ --- ### Create an Ansible Repository `pulp ansible repository create --name myrepo` --- ### Create an Ansible Remote `pulp ansible remote -t collection create --name basic --url https://galaxy.ansible.com --requirements-file ~/Documents/Presentations/container_demo/basic.yml` --- ### Create an Ansible Distribution `pulp ansible distribution create --name mydistro --base-path foo --repository myrepo` --- ### View it through the Galaxy API http://localhost:8080/pulp_ansible/galaxy/foo/api/v3/collections/ --- ### Sync content using the Remote into the Repo `pulp ansible repository sync --name myrepo --remote basic` --- ### Installing using the CLI 1.
