STILL can't launch Docker in 6b8

[dtempleton]

I have followed the threads about issues with getting Docker to start in beta 8.  I had it running in beta 7 with gfjardim's dockerMan plugin. 

 

Following various threads, I removed all of the dockerMan plugin parts, and deleted the btrf subvolumes, eg:

http://lime-technology.com/forum/index.php?topic=34980.0

and pducharmes' instruction for removing btrf subvolumes that I can't find now.

 

Then I restarted in beta8.  Then I installed the beta8 version of dockerMan.

https://raw.githubusercontent.com/gfjardim/dockers/beta8/dockerMan/dockerMan.plg

(I don't see dockerMan on the extension page)

 

Trying to install the dockerMan again shows:

/usr/local/sbin/plugin install https://raw.githubusercontent.com/gfjardim/dockers/beta8/dockerMan/dockerMan.plg 2>&1 2>&1
plugin: installing: https://raw.githubusercontent.com/gfjardim/dockers/beta8/dockerMan/dockerMan.plg
plugin: not reinstalling same version

 

 

 

 

pushing "start" on the Extentions:Docker page of the webgui does nothing, while running the equivalent /etc/rc.d/rc.docker in terminal gives this error:

 

root@Tower:/etc/rc.d# rc.docker start
Creating new image file for Docker:  size: 4G
fallocate: : open failed: No such file or directory
Not starting Docker: failed to create image file

 

Trying the Docker extension again the syslog shows a similar error:

Sep  3 11:38:27 Tower php: /etc/rc.d/rc.docker start
Sep  3 11:38:27 Tower php: Creating new image file for Docker:  size: 4G 
Sep  3 11:38:27 Tower php: Not starting Docker: failed to create image file 

 

I have a btrfs cache drive (256G) that is (or was) the home of my docker install and apps, but I don't see how to specify that target now.

 

Thanks for any help

You don't have to install anything in beta8, just point it to a docker.img  and select the size in GB's.  All your dockers will be stored in that img file.

Wait what? So a single monolithic img? For all containers?  Not one per container?

where is this docker.img file - non existeng on my system

Absolutely.  The Docker Start page defaults to /mnt/disk1/docker.img but this doesn't exist and the path is greyed out in the field. 

 

Oh!  I pointed this field to /mnt/cache/docker.img and it made a nice 4GB image for me, and Docker listed as 'started'.  Lemme play with that for a bit.

 

non-intuitive, I think.

i guessed so and tried it 1st but the greyed out field is not editable in my system

turned out its my browser 's noscript that blocked me

On mine it wasn't editable but you could type the correct path over it.
