PulpV3GapAnalysis¶

Content Tab¶

Content -> Red Hat Repositories¶

Katello knows the content URLs from candlepin, matches on the CDN, presents them to the user, the user selects them

• Katello creates a Repo tracking this in Pulp with client certificates and CA certificate
• Katello specifies custom options from the 'Custom Repo Creation Page' but these use cases are covered in that section

Katello deletes a Repository

Content -> Products¶

Content -> Products -> New Product (used for things like CentOS, SLES, etc)¶

All data here is stored only in Katello since this is a Product not a Repository and Pulp doesn't have a concept of a Product
Sync Plans will not be handled inside of Pulp

Content -> Products -> {product_name} -> Repositories¶

The user selects a type and content-specific fields are shown.

Publish Settings¶

• Checksum: (choice) Default, sha256, sha1 <----- for all repodata including primary.xml

Content -> Products -> {product_name} -> Repositories -> {repository_name}¶

This displays a created repository.

Katello allows the user to upload a package

• Receives the data from the user, sends it to Pulp

• Relies on Pulp to fully parse the metadata and create the unit <------- REQUIREMENT: must have Pulp determine all metadata

• Associates the the unit with the repository

Katello Reads a content Summary on this page

Content -> Products -> {product_name} -> Repositories -> {repository_name} -> Select Action -> Sync Now¶

Katello tells the remote associated with the repository to sync

Content -> Products -> {product_name} -> Repositories -> {repository_name} -> Select Action -> Advaced Sync¶

Katello can peroform an 'Advnaced Sync':

Optimized Sync - Normal sync, presented

Complete Sync - force-full on sync and force-full on publish <--------------------- GAP because we don't have force-full

Validate Content Sync - performs a checksum validation on all packages

• True Purpose: Validate existing downloaded content and redownload if the file(s) are missing or corrupt, redownload them. <-------- GAP

Content -> Products -> {product_name} -> Repositories -> {repository_name} -> Select Action -> Republish Repository Metadata¶

Republishes the metadata.

• Katello would create a new Publication and update the Distribution

Content -> Products -> {product_name} -> Repositories -> {repository_name} -> Select Action -> Delete a Repository¶

Deletes a repository

Content -> Products -> {product_name} -> Repositories¶

This is the index view of all repositories

Repsitories in Katello can have the same name, but Pulp enforces a unique name on repositories globally <--------- GAP

Katello takes a Product ID which resolves to a set of repos. Katello fetches this set of repos. For each repo we need to fetch:

• name (str)

• type (str), e.g. 'yum'

• sync status, e.g. 'Not synced, Pending, Error' <------------------------- GAP this would require a second call to load the data per Remote

• Content Summary, e.g. 2 packages, 5 errata, etc. Similarly for other types.

Katello can trigger a sync of one or more Repositories at once.

• Trigger the sync on one or more Remotes as independant calls

Katello can trigger a delete of one or more Repositories at once.

• Trigger the delete call to Pulp as independant calls

Search/Filtering of the list of Repositories, for Repository attributes

• content_type: the type of content

• content_view_id: the id of the content View <-------- not in Pulp anywhere currently

• ignore_global_proxy <--------- GAP area, not currently in Pulp, but probably should be

• name

• product

• redhat <---------- Anything added from Red Hat "Products" page in Katello gets Red Hat.

Search/Filtering of the list of Repositories, for content units

• distribution_arch:

• distribution_bootable <----------- if Katello can detect if it has a vmlinuz init.rd it knows the distribution is bootable. Detected at the end of every sync.

• distribution_family

• distribution_uuid

• distribution_variant

• distribution_version

NOTE: Must not have to make a call for each item in a list page. Must be able to make one call.

Content -> Products -> {product_name} -> Repositories -> {repository_name} -> Packages¶

Lists packages in a repository (the latest repository version)

Removing packages from the repository

• Can remove n packages from the repository
• Republish, Redistribute the repository

Content -> Content Credentials¶

Content -> Content Credentials -> GPG Keys¶

GPG keys can be created and stored by Katello
Pulp3 recommendation is to use pulp_file to hold the GPG keys hosted for clients to receive

Content -> Content Credentials -> SSL Certificate (GAP. This whole section is a GAP b/c Pulp doesn't "host" SSL certs, you have to manually install them on the filesystem first)¶

Stores SSL certificates for use by Pulp at sync time as CA cert, client cert, or client key

• name
• value

Supports updating them
Support deleting them
Support searching them (name, organization_id)
SSL Certs are per-product, so Katello needs some way to restrict the set of available SSL certs for the current "product"

Content -> Sync Plans¶

Sync plans will not be handled by Pulp 3, Katello/Foreman will handle scheduling.

Content -> Sync Status¶

Show the most-recent sync status from dynflow data. That data is populated by task status results from Pulp, which needs to contain at a minimum:

• start time
• create time
• end time
• state
• progress reports
• fatal errors
• non-fatal errors

Content -> Lifecycle¶

Content -> Lifecycle Environments¶

Creates a lifecycle environment

• Does not involve Pulp

Content -> Lifecycle Environments -> {name} -> Details¶

Each lifecycle environment has a 'Registry Name Pattern'. <------- GAP (specific to Docker only)

• Likely going to be on the Distributor

• Katello would use the template to produce a concrete value to set on the Distributor

• Important to ensure that two Distribution don't both receive the same concrete values

Content -> Lifecycle Environments -> {name} -> Content Views¶

Filterable by:

• composite
• label
• name
• organization_id

Content -> Lifecycle Environments -> {name} -> Yum Repositories¶

Content will come from CV section on Yum Repositories

Content -> Lifecycle Environments -> {name} -> Errata¶

Content will come from CV section on Errata

Content -> Lifecycle Environments -> {name} -> Packages¶

Content will come from CV section on Packages

Content -> Lifecycle Environments -> {name} -> Puppet Modules¶

Content will come from CV section on Puppet Modules

Content -> Lifecycle Environments -> {name} -> Container Image Tags¶

Content will come from CV section on Container Image Tags

Content -> Lifecycle Environments -> {name} -> OSTree Branches¶

Content will come from CV section on OSTree Branches

Content -> Content Views¶

Content -> Activation Keys¶

Content -> Content Types¶

Content -> Deb Packages¶

Content -> Container Image Tags¶

Content -> Errata¶

Content -> Files¶

Content -> OSTree Branches¶

Content -> Packages¶

Content -> Puppet Modules¶

Hosts -> Content Hosts¶

Non UI things¶

• the API endpoint that clients upload their enabled repos
• the API endpoint that clients upload their package profiles
• the API endpoint that clients register
• the API endpoint that clients unregister
• speed throttling and other global settings?
• Errata mailer
• smart proxy page/details

Terminology¶

Candlepin Manifest - Defines Products, Subscriptions, and a Content Sets
Product - A collection of repositories. A repository can only belong to one product
Repository Set - Has a name, Label, and URL of the form: /content/rhel/server/7/$RELVER/$BASEARCH/os/
