Photon RPM OSTree: 4 Querying for commit, file and package metadata
Danut Moraru edited this page Sep 17, 2015

12 revisions
There are several ostree and rpm-ostree commands that list file or package data based on either the Commit ID, or Refspec. If Refspec is passed as a parameter, it's the same as passing the most recent commit ID (head) for that branch.
For a host that is freshly installed, there is only one commit in the history for the only branch.
root@photon-host-def [ ~ ]# ostree log photon/tp2/x86_64/minimal
commit 2940e10c4d90ce6da572cbaeeff7b511cab4a64c280bd5969333dd2fca57cfa8
Date: 2015-08-20 22:27:43 +0000
Version: 1.0_tp2_minimal
This commit has no parent; if there was an older commit, it would have been listed too. We can get the same listing (either nicely formatted or raw variant data) by passing the Commit ID. Just the first several hex digits will suffice to identify the commit ID.

This command lists the file relations between the original source Linux Photon filetree and the deployed filetree. The normal columns include file type type (regular file, directory, link), permissions in chmod octal format, userID, groupID, file size, file name.

By default only the top folders are listed, but -R will list recursively. Let's list all which related files.
root@photon-host-cus1 [ /ostree/repo ]# ostree ls photon/tp2/x86_64/minimal -R | grep which

To diff the current /etc configuration versus default /etc (from the base image), this command will show the Modified, Added and Deleted files:

As expected, there is an rpm-ostree command that lists the packages for a commit or a branch, extracted from RPM database:

We are able to use the query option of rpm to make sure the newly added packages have been installed properly. The files list should match the previous file mappings. Let's check package which.

The RPM database is not writable any longer. The idea is that preparing the packages should be done via server tree composition and deployment at host should bring them installed into a read-only directory and recorded into the read-only RPM database.
To prove that, installing with tdnf will return an error.
root@photon-host-def [ ~ ]# tdnf install --nogpgcheck openjdk
