YAML to bundle URL:
# BasicBrooklynCatalog.collectCatalogItemsFromItemMetadataBlock turns the YAML
into instances of {{CatalogBundle}}.
# CatalogUtils.installLibraries turns each {{CatalogBundle}} into a
{{BasicManagedBundle}}.
# OsgiArchiveInstaller.makeLocalZipFileFromInputStreamOrUrl passes the bundle's
URL to {{ResourceUtils}}.
> Catalog libraries: externalized config for basic-auth credentials in url (via
> YAML)
> -----------------------------------------------------------------------------------
>
> Key: BROOKLYN-421
> URL: https://issues.apache.org/jira/browse/BROOKLYN-421
> Project: Brooklyn
> Issue Type: Bug
> Affects Versions: 0.10.0
> Reporter: Aled Sage
>
> A customer wants to use YAML catalog items, where the library bundles are
> retrieved from their Nexus repo using basic-auth. They want the nexus
> credentials to be stored in an externalized credential store. They want the
> credentials to be able to contain special characters (e.g. "@") that are not
> valid in a URL.
> Building up to this, here is what we currently support...
> Either of the catalog items below is valid (i.e. the credentials can be
> encoded in the url; the library can be supplied either as a string or as a
> map (where the map currently takes keys of "url", "name" and "version")):
> {noformat}
> brooklyn.catalog:
> id: simple-example
> version: "1.0"
> itemType: template
> libraries:
> - url: https://myuser:[email protected]/mybundle.jar
> item:
> ...
> brooklyn.catalog:
> id: simple-example
> version: "1.0"
> itemType: template
> libraries:
> - https://myuser:[email protected]/mybundle.jar
> item:
> ...
> {noformat}
> For usernames / passwords with special characters, these need to be escaped
> before adding to the url. For example, for username "[email protected]", the
> url would be
> {{https://myuser%40mydomain.com:[email protected]/mybundle.jar}}.
> For externalized config, one can use the example below:
> {noformat}
> brooklyn.catalog:
> id: simple-example
> version: "1.0"
> itemType: template
> libraries:
> - $brooklyn:formatString:
> - https://%s:%[email protected]/mybundle.jar
> - $brooklyn:external("myprovider", "username")
> - $brooklyn:external("myprovider", "password")
> item:
> ...
> {noformat}
> However, this requires that the externalised config stores the username and
> password in its url-escaped form (rather than as the raw password).
> It also means that the password is embedded in the url, which is potentially
> logged or persisted.
> ---
> We could fix the first of these problems (i.e. credentials store can just
> supply the raw username/password) by adding DSL support for
> {{$brooklyn:escapeUrl}}. One could write something like:
> {noformat}
> brooklyn.catalog:
> id: simple-example
> version: "1.0"
> itemType: template
> libraries:
> - $brooklyn:formatString:
> - https://%s:%[email protected]/mybundle.jar
> - $brooklyn:escapeUrl:
> - $brooklyn:external("myprovider", "username")
> - $brooklyn:escapeUrl:
> - $brooklyn:external("myprovider", "password")
> item:
> ...
> {noformat}
> ---
> Alternatively (as well?) we could supply the basic-auth credentials as an
> explicit configuration option. The advantage of this is that we should be
> able to keep it as the DSL "deferred supplier" so not persist the password.
> For example, something like the YAML below:
> {noformat}
> brooklyn.catalog:
> id: simple-example
> version: "1.0"
> itemType: template
> libraries:
> - url: https://nexus.example.com/mybundle.jar
> basicAuth:
> username: $brooklyn:external("myprovider", "username")
> password: $brooklyn:external("myprovider", "password")
> item:
> ...
> {noformat}
> However, this is fiddly to implement. Looking at the code path for where it
> eventually loads the bundle over http(s):
> {noformat}

> have the {{CatalogBundle}} object - after that, we only have the URL string.
> So that is a lot of methods that would need to change!
