[TKLDev] Problems using TKLDev on Docker or OpenStack
Hello, i am trying to use tkldev for creating new products.
First, i used the tkldev Docker's image (from: spam filter) but i got the following error:
root@9ec4e2bbb35f products/core# make
deck /turnkey/fab/bootstraps/wheezy build/bootstrap
Traceback (most recent call last):

To obtain this error, i followed this steps: pastebin.com/eYeAtE8M from the tkldev guide (redacted for the spam filter).

Reply 1Hi Geoffroy
Reply 2Firstly sorry about the problems you've had with the spam filter. Thanks for persisting. FWIW I have tweaked your account settings a little and hopefully you shouldn't have further issues posting. Please do not hesitate to email if you get stuck again (jeremy AT turnekylinux.org).
With regards to your issues with the Docker image, my suspicion is that we should probably pull the Docker build of TKLDev (and the LXC and OpenVZ builds too). I have just done a little research and it seems that currently all Linux containerised Debian Wheezy based builds (including TurnKey Docker, LXC and OpenVZ builds) have issues doing many sorts of mounts inside the container. It appears that there are workarounds and recent versions of Docker have patched this but it's outside the scope of TKL to provide those sort of fixes (or even documentation IMO - although if you'd like to pursue that then please feel free to do so and preferably share! :).
TBH I'm not sure what this will mean for future TKL builds, but I guess that's pretty much irrelevant to your current situation... Long story short, it appears that TKLDev does not work properly containerised...! Actually off on a tangenet, my research suggests that AuFS support does not exist in mainline kernel anymore and is being added by Debian and Ubuntu (and no other distros that I could find). As all containers rely on the host kernel this will probably never work (without serious tweaking of the host kernel). We may need to reconsider the use of AuFS in TKLDev and switch to something else... Anyway I digress...
With regards to point 1 of your second post, there is general acknowledgement that the OpenStack build needs some tweaking (see Issue #254). As an OpenStack user, if you have anything to add to that then it would be greatly appreciated. Also if you are interested in using OpenStack images then this thread is probably of value to you and especially the commit linked to in this post.
As to the error though, TBH I'm not quite sure...!? Can you please confirm that you have done the initial setup completely - i.e.:
cd /usr/local/sbin wget https://raw.githubusercontent.com/turnkeylinux-apps/tkldev/master/overlay/usr/local/sbin/tkldev-setup chmod +x tkldev-setup ./tkldev-setup
To bypass this error i tried to use the OpenStack image (from: spam filter) and came accross 2 problems:
I think i am doing something wrong but i didn't find any clues or info on the actual errors. So if anyone managed to use tkldev on OpenStack or Docker can you give me the correct steps.
Thanks - Geoffroy
