Red Hat Satellite engineering is moving the tracking of its product development work on Satellite to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "Satellite project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs will be migrated starting at the end of May. If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "Satellite project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/SAT-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Og Maciel 2015-07-23 20:30:20 UTC 
Description of problem:

The issue is related to trying to provision a new Docker container by going directly to the Red Hat registry (akin to going straight to Docker Registry hub). Once you've gone through the new container wizard, the provisioning process fails with no indication in the UI as to what has happened. In /var/log/messages one sees:

Jul 23 16:11:52 ibm-x3250m4-06 docker: v1 ping attempt failed with error: Get https://registry.access.redhat.com:/v1/_ping: dial tcp 10.4.164.31:0: connection refused. If this private registry supports only HTTP or HTTPS with an unknown CA certificate, please add `--insecure-registry registry.access.redhat.com:` to the daemon's arguments. In the case of HTTPS, if you have access to the registry's CA certificate, no need for the flag; simply place the CA certificate at /etc/docker/certs.d/registry.access.redhat.com:/ca.crt


Version-Release number of selected component (if applicable):

* Satellite 6.1.1. SNAP 13

How reproducible:


Steps to Reproduce:
1. Create a new container Registry pointing at http://registry.access.redhat.com
2. Create a new Docker compute resource (I used my own satellite for this using the instructions from the official Satellite 6.1 User Guide (Chapter 8) 
3. Create a new Docker container, choosing the Registry option from the Wizard and selecting the Red Hat registry

Actual results:

Once you have gone through the wizard, and click the Submit button, nothing happens

Expected results:

Comment 1 Og Maciel 2015-07-23 20:35:01 UTC 
Interesting that if one uses https and not http, then the above scenario works. Since this is something different from what used to work before, I'm asking DEV for help to determine if this needs to be changed to a DOCs issue or release notes?
Comment 6 Jay Greguske 2016-04-06 13:01:27 UTC 
Not sure who Jeff is, but passing the buck to Chris Bredesen! The public volume we use for serving out docker content is only available over https, but I don't know the reason why. https is a good idea in general, but maybe Chris can explain the business reasons better than I.
Comment 7 Chris Bredesen 2016-04-06 17:46:21 UTC 
You should not be able to talk to a registry with modern Docker clients over HTTP without --insecure-registry. Why are we trying to do this? It isn't clear to me from my first read of this BZ....

Comment 9 Bryan Kearney 2017-01-13 19:44:45 UTC 
This is an older bug which I do not envision being addressed in the near term. I am closing this out. If you believe doing so is an issue, please feel free to re-open and provide additional business information. Thank you.
