Docker container lifecycle management (mgt=docker, mkdocker, rmdocker,
lsdocker) was added in 2015-2016 as an experiment targeting Docker API
v1.22 on Ubuntu only. Documentation and man pages were deliberately
removed in 2019 (PRs #6222 and #6324) with the original developer's
approval, noting that "the interface of Docker has become very simple
right now, so there is no value for xCAT to offer such functions."
The plugin was still being shipped but has had no functional code changes
since April 2016, was never listed as a valid mgt value in Schema.pm,
and no user ever filed an issue about it.
Removed:
- xCAT-server/lib/xcat/plugins/docker.pm (1,142 lines)
- xCAT/postscripts/setupdockerhost
- xCAT-server/share/xcat/scripts/setup-dockerhost-cert.sh
- xCAT-test/autotest/testcase/dockercommand/ (test cases)
- Docker attribute definitions in Schema.pm
- Client symlinks (mkdocker, rmdocker, lsdocker)
- Usage entries and dockerhost cert handling in credentials.pm
- Docker attribute documentation in man7 pages
The "Running xCAT in Docker" documentation (dockerized_xcat/) is
retained as it documents containerizing xCAT itself, not the removed
mgt=docker feature.
Closes#7518
* Fixes in xdcpmerge.sh
Two fixes:
1. The grep pattern when finding duplicate usernames is missing ":" at the end. So, for example user "test" would also match "test2, etc.". Adding the ":" delimiter fixes the issue.
2. Another issue happens when the file to be merged is a superset of the files on the nodes. For example, if a new user is added and entire passwd file (that is otherwise identical) is sent to be merged. In this case, the $filebackup.nodups file, i.e. the original file with duplicates removed, becomes empty and the condition "if [ -s "$filebackup.nodups" ]" does not execute. Then the merged file ends up being original file with the merge file fully appended, clearly not what was intended.
This is solved by changing the condition to check for file existence "-a" rather then for size. Additionally, I also turn the logic around so that the duplicates are removed from the merge file and then added to the original file. I think this makes logic a bit cleaner and also ensures that existing entries are not reordered or changed in any way.
* Streamlining previous commit
Adjustment to previous commit, streamlining and simplifying logic. Once $mergefile.nodups is created, just concatenate it the original file.
* Update to xdcpmerge
No need to copy $filebackup to $curfile, they are the same.
