ISO Plugins¶

ISO Type¶

The ISO Plugins only have one type, the ISO. The ISO type’s ID is iso. The following is a descripton of the ISO unit type that is used by the ISO plugins. The unit key is a combination of fields that can be used to uniquely identify an ISO. ISOs have no additional metadata.

Unit Key¶

The unit key for the ISO type is an ordered list of name, checksum, and size. Each of these attributes is described below.

name: This is the filename of the ISO.
checksum: This is the SHA-256 checksum of the ISO file.
size: This is the size in bytes of the ISO file.

Metadata¶

ISOs have no additional metadata outside of the unit key.

ISO Importer¶

The ISO Importer can be used to sync an ISO repository with an upstream feed. The ISO Importer ID is iso_importer.

An ISO repository is a fairly basic type of repository. It should be accessible via feed, and there should be a file named PULP_MANIFEST available by appending /PULP_MANIFEST to the feed. For example, if the feed is http://example.com/iso_repository, the ISO Importer will look for the manifest at http://example.com/iso_repository/PULP_MANIFEST.

The manifest should be a CSV file with one row per ISO and these three columns, in order: name, checksum, and size. The CSV file should not have a header row. The name should be the filenames of the ISO, and the ISO should be accessible by appending the name to the feed. The checksum should be the SHA-256 checksum of the ISO, and the size column should represent the size of the ISO in bytes. Here is an example PULP_MANIFEST file:

example-1.0.iso,f02d5a72cd2d57fa802840a76b44c6c6920a8b8e6b90b20e26c03876275069e0,127346
example-1.1.iso,c7fbc0e821c0871805a99584c6a384533909f68a6bbe9a2a687d28d9f3b10c16,564830

This file can be generated by a script such as:

#!/usr/bin/env bash

for file in $@
do
  echo $file,`sha256sum $file | awk '{ print $1 }'`,`stat -L -c '%s' $file`
done

If the above script is named script.sh it can be run in the directory with the isos with: ./script.sh *.iso > PULP_MANIFEST.

Configuration Parameters¶

The following configuration parameters are all optional, and can be used to determine the behavior of the ISO importer.

feed: This should be a string that represents the URL to an upstream ISO repository that you would like this importer to be able to synchronize with. This parameter is optional because it is valid to create an ISO importer that does not synchronize with an upstream feed, but is rather used to contain uploaded ISOs, or ISOs that are copied from other repositories. This parameter becomes required if any of the other parameters are provided.
max_speed: This should be a numerical value, or a string that can be interpreted as a numerical value, representing the maximum speed that the importer should be allowed to transfer ISOs at when synchronizing with feed. It should be specified in units of bytes per second.
max_downloads: This should be an integer, or a string that can be interpreted as an integer, representing the maximum number of concurrent downloads that should be performed when synchronizing with feed. This parameter defaults to 5.
proxy_password: A string representing the password that should be used to authenticate with the proxy server specified in proxy_host. This parameter is required if the proxy_username is provided.
proxy_port: An integer, or a string that can be interpreted as an integer, representing the port that should be used when connecting to proxy_host.
proxy_host: A string representing the URL of the proxy server that should be used when synchronizing with feed. This parameter is required if any of the other proxy setting are provided.
proxy_username: A string representing the username that should be used to authenticate with the proxy server at proxy_host. This parameter is required if the proxy_password is provided.
remove_missing: This is a boolean value, or a string “True” or “False”. If set to “True”, the importer will remove any ISOs that are currently in the local Pulp repository that are not found in the manifest at feed. If “False”, missing ISOs will not be removed. This parameter defaults to False.
ssl_ca_cert: This is a string representing the SSL certificate authority certificate that should be used to validate the server responding at feed. It should be provided in PEM format.
ssl_client_cert: This is a string representing the SSL client certificate that should be used to authenticate the importer to the upstream repository at feed. It should be provided in PEM format. This parameter is required if the ssl_client_key is provided.
ssl_client_key: This is a string representing the private key for ssl_client_cert. It should be provided in PEM format.
ssl_validation: This is a boolean that indicates whether we should verify the remote feed against the given ssl_ca_cert.
validate: This is a boolean value, or a string “True” or “False”. If set to “True”, the importer will check the downloaded ISOs’ file sizes and checksums against the expected values in the manifest when downloading from feed. If “False”, no validation will be performed. This parameter defaults to True.

ISO Distributor¶

The ISO Distributor can be used to publish available ISOs in an ISO repository over http or https. It is distinct from the export_distributor. The ISO Distributor ID is iso_distributor.

Configuration Parameters¶

The following configuration parameters can be used to determine the behavior of the ISO Distributor. Both configuration parameters are required.

serve_http: This is a boolean value, or a string “True” or “False”. If set to True, the distributor will publish the ISO repository over plain HTTP, port 80. If False, it will not be published over plain HTTP.
serve_https: This is a boolean value, or a string “True” or “False”. If set to True, the distributor will publish the ISO repository over SSL protected HTTP, port 443. If False, it will not be published over HTTPS.
ssl_auth_ca_cert: If the distributor is configured with an authorization CA certificate and the repository protection WSGI app is enabled, the distributed repository will become a protected repository. The given CA certificate will be used to verify the clients’ entitlement certificates. If this certificate is not provided, the repository will be an unprotected repository.

relative_url The path at which the repository will be served, relative to the root configured in /etc/httpd/conf.d/pulp_rpm.conf. The default root is /pulp/isos.
