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
* Fix silent failure when site.master is not set (#6157)
Hardware control commands (rpower, rinv, etc.) silently return no output
and exit 0 when site.master is empty. The original fix (#6074) was
reverted (#6158) because it warned per-node with the wrong hostname.
Check once in plugin_command before dispatching to plugins, so the error
appears exactly once with the correct command name.
* Also reject empty site.master, not only undef
The else branch handles a rare case where XS libraries (Sys::Virt,
Net::SNMP) crash without setting $@. This IS a plugin bug, so keep
that label and the debug hint. Only the common case (die with $@)
gets the clean passthrough.
When a plugin dies during request processing, xcatd wrapped the error
in a misleading "plugin bug" message that hid the real cause (e.g.
"No space left on device"). Now passes through the actual error from
the eval, making the output useful for any failure, not just disk full.
Fixes#2719
This commit adds an early return to xcatconfig settunnables function.
This function set parameters at
/proc/sys/net/ipv4/neigh/default/gc_thresh1
/proc/sys/net/ipv4/neigh/default/gc_thresh2
/proc/sys/net/ipv4/neigh/default/gc_thresh3
And set sysctl attributes by writing to /etc/sysctl.d/ and
/etc/sysctl.conf
These are tunning network parameters for running on production
and should not affect the overall function for testing purposes.

On Debian-based systems, /etc/sysctl.conf doesn't exist and
/etc/sysctl.d/ directory is used instead. Modified xcatconfig
to prefer /etc/sysctl.d/99-xcat.conf when the directory exists,
falling back to /etc/sysctl.conf for backward compatibility.
- detect provisioning when updateing status to installing/netbooting
- consistent message format "xcat.updatestatus - ($node): changing status=($status)" (no need to log the time as syslog has the timestamp)
* site cache when run plugin does not work very well
- using cache from plugin when getNodesAttribs/getNodeAttribs (pass it into DB process from plugin process)
- Site cache is a whole hash, so to use cache when by the hash is there, instead of the specified key is there.
It is because that there might be no key defined in site table.
* with XCATBYPASS, to populate site hash before scan_plugins. Then only 1 query for site table to do whole things.
* cache site when init plugins on service nodes
* missing to comment the old codes query from xCAT DB process
