[Pulp-list] Pulp 3.15 content only server

[Mike DePaulo]

Hi Bin,

Using the Pulp3 Ansible Installer, we do not support a read-only server
like you want. The installer could be extended to support it, as pulp 3
does support it, but we do not currently support it and overcoming #7 below
would be time-consuming.

The closest you can do with the current installer (or 3.15's installer) is:
1. Run pulp_content and pulp_webserver against this server.
2. You would configure pulp_webserver to talk only to that pulp_content
instance by leaving pulp_content_bind at its default of "127.0.0.1:24816"
for this host (or use a unix domain socket).
3. You'd have to point to another pulp_api server (pulp_api_bind) and redis
(pulp_settings.redis_host).

Additionally, with manual configuration you can accomplish what you want:
4. Manually install & configure the redis instance to be a replica. See our
pulp_redis role on how to install it and how to configure it to listen on
the network: it is relatively simple to read & understand. You should
actually do this before running pulp_content and pulp_webserver.
5. When running the installer against this host, pulp_settings.redis_host
defaults to `localhost`, which is what you'd want instead of pointing to
another pulp_redis server (contradicts #3).
6. After running the installer, manually adjust the apache/nginx config
files (nginx.conf & pulp-vhost.conf) placed by pulp_webserver to not talk
to any pulp-api server. pulp_webserver's  pulp_content_bind variable
defaults to localhost, which makes things easier.)
7. After running the installer, manually adjust the webserver snippets from
plugins (e.g., pulp_container.conf) to not talk to any API server.

See
https://docs.pulpproject.org/pulp_installer/customizing/#separate-servers-for-each-and-every-service
for a different example of multiple hosts, each host having a roles lists &
variables.
