How to mimic Satellite decision what Capsule is used for Remote Execution?

Solution Verified - Updated

Environment

Red Hat Satellite 6.11 or newer

Issue

  • Trying to run Remote Execution of some Host(s) registered via Capsules, unexpected Capsule is sometimes selected for connecting to the Host(s). Is there a way to understand the decision behind that?

Resolution

Create file /usr/share/gems/gems/foreman_remote_execution-*/lib/tasks/explain_proxy_selection.rake with a specified content:

curl https://raw.githubusercontent.com/adamruzicka/foreman_remote_execution/88b44de1fd1f00fe88f1402acf7a06077203ecbc/lib/foreman_remote_execution/tasks/explain_proxy_selection.rake > explain_proxy_selection.rake

mv explain_proxy_selection.rake /usr/share/gems/gems/foreman_remote_execution-*/lib/tasks/

Then run:

# foreman-rake foreman_remote_execution:explain_proxy_selection PROVIDER=SSH HOST=host.fqdn

PROVIDER=SSH is the way of connecting to the system, wither plain SSH or Ansible, and host.fqdn is the Host's FQDN.

Example output showing what Satellite/Capsule will be used by what strategy and why:

# foreman-rake foreman_remote_execution:explain_proxy_selection HOST=pmoravec-rhel7.gsslab.redhat.com PROVIDER=SSH
=> Host pmoravec-rhel7.gsslab.redhat.com
==> Strategy subnet
 no proxies available using this strategy

==> Strategy fallback
 strategy is disabled

==> Strategy global
 1) pmoravec-caps612.gsslab.redhat.com - 0 tasks
 2) pmoravec-sat612.gsslab.redhat.com - 1 tasks

==> Strategy registered_through
 1) pmoravec-sat612.gsslab.redhat.com - 1 tasks

As of now, SSH job would use proxy pmoravec-sat612.gsslab.redhat.com, determined by strategy global.
