#249 Look into and possibly patch unit files for imagefactoryd

Closed: Fixed 7 years ago Opened 7 years ago by tflink.

We use imagefactory to build the images that we use on the Taskotron workers and distribute those images. When we last rebooted qa12, imagefactoryd didn't start up and it doesn't seem to want to be enabled:

# systemctl status imagefactoryd
● imagefactoryd.service
   Loaded: loaded (/usr/lib/systemd/system/imagefactoryd.service; static; vendor preset: disabled)
   Active: active (running) since Wed 2018-02-07 12:15:11 UTC; 13s ago
  Process: 32038 ExecStart=/usr/bin/imagefactoryd (code=exited, status=0/SUCCESS)
 Main PID: 32041 (imagefactoryd)
    Tasks: 11 (limit: 7372)
   CGroup: /system.slice/imagefactoryd.service
           └─32041 /usr/bin/python /usr/bin/imagefactoryd

Figure out if we need to change how we're enabling the imagefactoryd service to start on boot or if we may need to send a patch upstream so that it can be enabled to start on boot.

imagefactoryd.service file is not a proper service file. I've reported this issue to the upstream ( https://github.com/redhat-imaging/imagefactory/issues/417 ).

Apart from that, proposed fix is to do following in our ansible play:

diff --git a/roles/taskotron/imagefactory/tasks/main.yml b/roles/taskotron/imagefactory/tasks/main.yml
+ - name: allow imagefactoryd.service to be enabled
+    blockinfile:
+    path: /etc/systemd/system/imagefactoryd.service
+    block: |
+      [Unit]
+      Requires=libvirtd.service
+      After=libvirtd.service
+
+      [Service]
+      Type=forking
+      ExecStart=/usr/bin/imagefactoryd
+      ExecStop=/usr/bin/killall imagefactoryd
+      PIDFile=/var/run/imagefactoryd.pid
+      LOCKFile=/var/lock/subsys/imagefactoryd
+
+      [Install]
+      WantedBy=multi-user.target

The indentation is off. It shouldn't work as it is currently written. See ansible-doc blockinfile for examples.

Please use a standard file for this that you just copy over (stored in files/). Or is there a reason to use blockinfile instead?

Please include the link to the bug as a comment above the task (something like "This is a workaround for: <buglink>". The name will now probably be something like "fix issues in imagefactoryd.service`, since we now fix several things.

Please try changing LOCKFile to a proper name (and test whether it works).

Please note you'll need to call daemon-reload if the service file was changed, before you try to enable it. See buildmaster-configure/tasks/main.yml for inspiration.

I was hoping you wouldn't notice... I was too lazy to do a proper git diff, so I just "made it by hand" :)
