If you look on the hosts, do you see the /usr directory there? I don't see how this would be Buidlah's fault. All of the directories in the contianer, are setup automatically other then /etc? Although I would bet the only content in /etc/ is the /etc/resolv.conf. This really looks like their is no image at all.
@rhatdan - thanks for the comment. Yes, I can see the host has everything alright. Here is the full dump:

What does the mount command show as the lower directory for the contianer? Is there any content in it. It looks to me like the lowerdir is a scratch directory.
@rhatdan - lower is empty. In fact except merged
, all others - lower, work, diff and link are all empty!
Again, without knowing too much internals of buildah, I can say that this behavior is consistent with the scenario when the parent container (quay.io/biuldah/stable) was invoked without the volume mount of /var/lib/containers
. If you can assert that this is expected behavior under such circumstances then it is fine by me, and will have to deal it with minishift as to why the prescribed volume mount is not being honored. At this point, I am unsure of it. Please advise!
No what is supposed to happen, is the alpine image is supposed to populate the /var/lib/containers that you volume mounted in and then these other directories are mounton .
@rhatdan - thanks for your help as always! I have further done some work on the failing system, and have this observation. Though it is not a direct continuation of the previous diagnosis, I hope this brings some clues!
Did these in two identical boxes:
buildah --debug pull alpine 2> 1
buildah --debug from --name foo alpine 2> 2
buildah --debug mount foo 2> 3
passing system:
/var/lib/containers/storage/overlay/b788d08d19e2088bf63f52e2960ac6f41070210d28bea92624b90124a72adb14/merged

[root@g1 foo]
nothing!
the debug log of the mount command in the failing case shows an additional section as follows:
time="2019-08-28T14:43:22Z" level=debug msg="overlay: mount_data=nodev,metacopy=on,lowerdir=/var/lib/containers/storage/overlay/l/BDHSVFIXVDKG4RPQGFRBQKFXLY,upperdir=/var/lib/containers/storage/overlay/e74a02a55ea5c8708a6d051e5ac79d32db8c3875a3a93a635144dff40350e86d/diff,workdir=/var/lib/containers/storage/overlay/e74a02a55ea5c8708a6d051e5ac79d32db8c3875a3a93a635144dff40350e86d/work"
and its lowerdir
contain everything what we wanted!

Does this sound anything interesting, and does it provide additional clues? thanks!
btw, @rhatdan - just wanted to update you on my latest finding: with quay.io/buildah/stable:v1.9.0
I see both the above issues are resolved, issue is with the latest (I did not bisect to see precisely the breaking version though).
thanks for your help!
Ok so this is with the quay.io/buildah/latest? @TomSweeneyRedHat PTAL
@gireeshpunathil Can you try:

I think the only change here over yours is I went with Podman and added the `--device /dev/fuse:rw' With that change in play, I'm seeing the /usr dir in my container. Holler if I missed a step in your testing.
@TomSweeneyRedHat Nice catch, I forget about /dev/fuse, I wonder if we should make this a default?
@TomSweeneyRedHat - thanks. But it does not work!

Oh, yes I keep forgetting the seccomp rules in docker are stricter then in podman, basically Docker blocks all mount commands, even though bind mounts are safe. Although --privileged should have removed that.

Weird these all work fine for me. @giuseppe Any ideas? Is fusermount3 supposed to be in the container?
further info: last good build: v1.9.0
, first bad build: v1.9.1
. I could do a git bisect
, but unfortunately bit difficult to follow the build procedure. Is it documented somewhere, or can someone share it for me to follow? thanks!
@gireeshpnathil I'm not 100% sure of the build procedure that you're looking for? I use ./release.sh to create the initial commit then massage things by hand from there.
@rhatdan actually did both. 1.9.0 at: https://github.com/containers/buildah/pull/1676 1.9.1 at https://github.com/containers/buildah/pull/1716
if you search the closed PR's for the word "bump" you should see all of them. Is that what you're looking for?
Tagging @lsm5 in case he's thoughts.
@TomSweeneyRedHat - sorry if I confused you! my idea is:
git bisect
until I get a good build.v1.9.0
So, I am looking for a procedure on how to build the buildah execubale. I tried to follow the steps in the travis CI
, but looks like it has a lot of steps due to the fact that it has to spawn a container, download secrets ... etc.
@gireeshpunathil the confusion is probably all on my end, I've only had one cup of tea today, I'm way behind schedule!
After you've used git bisect
to determine the commit id that you want, can you do a bunch of git hackery? Setup a sandbox ala: https://github.com/containers/buildah/blob/master/install.md#installation-from-github and then:
git checkout -b test_branch {commitid}
make
make install
Apologies for the delay, was actually working to circumvent this issue back in my project. But now I have some updates:
I wasn't greatly successful with git bisect
: the image version v1.9.0
is just a month old, but in github commits, even if I traverse months together, I am uable to find a one that works on this machine!
then I took a different approach. I placed latest buildah
binary into v1.9.0
quay image and tested. It worked! Similarly, I placed the buildah
from v1.9.0
into the latest quay image, and it failed!
So the bottom line for me is that it is not buildah
, but something else in the image that is decisive.
And I zeroed down onto fuse-overlayfs
. If I manually upgrade it from a working image, it starts to fail. Here is the full dump:

Is there anything I can do? are there any debug options for this tool? thanks again!
ok, more findings: this time I am able to do git bisect
successfully, on the fuse-overlayfs
component. I hope we can continue conversation here, as these are very closely related projects? Let me know if that is not the case.
This commit https://github.com/containers/fuse-overlayfs/commit/35949df0bbbf507937f0ddafdb3557234531211e is the point of failure. Without knowing anything about the fuse
logic I cannot make any comments; but a wild guess is that fuse_buf_copy
did not seem to have happen under some unforeseen circumstances, due to which we see the merged
folder empty.
I have the full build environment and the failing system handy with me; so if you have any proposals on debug statements, patches, printfs etc. I am happy to follow it!
Copying @giuseppe to in case if he knows.
I did further debugging, and found that
makes the difference. If I comment that, the issue is resolved!
the documentation for this flag says:
Indicates that writeback caching should be enabled. This means that individual write request may be buffered and merged in the kernel before they are send to the filesystem.
This feature is disabled by default.
how do we know my kernel has the support for the writeback cache, and if yes, it works well?
If I were to suspect the libfuse
module on the host, this is what I have:
good system:
[root@g1 ~]# yum list installed | grep fuse
fuse.x86_64 2.9.2-11.el7 @Local-Base
fuse-libs.x86_64 2.9.2-11.el7 @Local-Base
glusterfs-fuse.x86_64 3.12.2-47.2.el7 installed
bad system:

fuse-libs.x86_64 2.9.2-11.el7 @base
glusterfs-fuse.x86_64 3.12.2-18.el7 @base
The only difference is in the glusterfs
, that too in the minor versios.
And that, did not yield any updates:
[root@h1 mount]# yum update glusterfs-fuse.x86_64

could you try disabling the writeback cache with?
[storage]
[storage.options]
mountopt = "writeback=0"
in your ~/.config/containers/storage.conf
file if running as rootless, or /etc/containers/storage.conf
when running as root in a container as in your use case?
alternatively, could you check if this fuse-overlayfs patch solves the issue:
diff --git a/main.c b/main.c

@giuseppe - this is the head of my /etc/containers/storage.conf
, the last line is my addition, based on your advice. Pasting it here to see if the syntax looks good to you or not as it did not work as expected. Also, do we need to do any refresh
? like `sysctl stop | start on some services?
the patch your provided works, many thanks!!! so that means the underlying host does not need any changes, if this change is going upstream? If so, what could have happened wrong with these systems? could you be so kind to please explain a bit, for my understanding?
thanks again!
@gireeshpunathil yes the conf file looks correctly.
libfuse checks whether some features are available and informs the FUSE program (fuse-overlayfs in this case) what can be requested. fuse-overlayfs didn't check for it, and assumed writeback is always supported, which from your bug report seems to not be the case.
PR opened here: https://github.com/containers/fuse-overlayfs/pull/117
thanks all for the help, really appreciated!!
I will watch out for a release being cut out of #117 , any rough estimate on the dates?
can some one advise me which buildah
release this fix was incorporated into? the reason why I ask is, I don't see the intended behavior with latest buildah releases. cc @rhatdan @TomSweeneyRedHat @giuseppe
Based on the log of differences between 0.6 and 0.7 (https://github.com/containers/fuse-overlayfs/compare/v0.6...v0.7), it should have been in 0.7.
@gireeshpunathil as @nalind pointed out, it's in the latest release. That being said, other than cloning and building fuse-overlayfs from GitHub, I'm not sure where you could get a rpm yet. @giuseppe or @lsm5 do you have any pointers?
Based on the log of differences between 0.6 and 0.7 (v0.6...v0.7), it should have been in 0.7.
@nalind - thanks, will check on that.
I actually meant buildah release or buildah container image that has this (good) version of fuse-overlay
@gireeshpunathil Buildah doesn't ship fuse-overlayfs. It is shipped separately.
What distro are you using? fuse-overlayfs 0.7 is already on Fedora 30/31 stable
@giuseppe - ah, thanks for the information. Will check on that.
So basically we should be good if I do:
yum update && yum install fuse-overlayfs
prior to the sequences in my first comment I guess?
@gireeshpunathil I'd go with yum update && yum update fuse-overlayfs
, then rpm -qa | grep overlayfs
, and verify the version.
@TomSweeneyRedHat - thanks. My main question (I acknowledge that did not come good) was whether we update fuse-overlayfs
on the host, or inside the (buildah) container?
@gireeshpunathil ah! Should only be on the host side that you will need to update fuse-overlayfs on, the container should be fine.
thanks @TomSweeneyRedHat for the clarification!
Failing case: missing mount binding to the parent container
Passing case: mount binding enabled to the parent container
So far so good. Now I converted this cli invocation into a tekton pipeline as follows (only the task steps are shown that is most relevant here)
The image
gireeshpunathil/foo
is essentially a thin layer on top ofquay.io/buildah/stable
.This works as expected with
minikube
. (just like second case above)This fails in minishift (just like first case above)
With my limited experience with
minishift
, I believe this has something to do with either:As I am not very sure about the root cause, and as the issue is manifesting as a buildah command failure, I am raising it here. Please advise, thanks in advance!
Additional info - queried from the faulty container:
excerpt from strace:
So! /usr and and many other system folders are missing! how this could be!
All other required info for the bug tracker (system information etc.) are precisely the same as in https://github.com/containers/buildah/issues/1814, so not duplicating here.
