in container: bind mount permission denied

[aminebizid]

I get this error
failed to solve: failed to mount /tmp/buildkit-mount123570778: [{Type:bind Source:/root/.local/share/img/runc/native/snapshots/snapshots/8 Options:[ro rbind]}]: permission denied

when running

running img build -t amine/api .

using this Dockerfile

FROM ttadockerregistry.azurecr.io/aspnetcore-build:2.0 AS build-env
WORKDIR /app

# Copy csproj and restore as distinct layers
COPY *.csproj ./
RUN dotnet restore

# Copy everything else and build
COPY . ./
RUN dotnet publish -c Release -o out

# Build runtime image
FROM ttadockerregistry.azurecr.io/aspnetcore:2.0
WORKDIR /app
COPY --from=build-env /app/out .
ENTRYPOINT ["dotnet", "api.dll"]

what is your ubuntu version can you also output img version, thanks!

[aminebizid]

uname -or
4.13.0-1016-azure GNU/Linux

img version
img:
version : v0.4.4
git hash : 3e14a5b
go version : go1.10.2
go compiler : gc
platform : linux/amd64

[jessfraz]

are you running it with sudo because it looks like it is trying to use /root/.local/share/img/runc/native/snapshots/snapshots/8 as the state dir which implies root... you shouldnt need sudo

I'm running into k8s with an ubuntu:14.04 image
Do I need to create a user?

[aminebizid]

when using a non root I get this

mg build -t test .
nsenter: cannot change root filesystem propagation: Permission denied

[jessfraz]

why not use the image I push?

yeah it won't work _inside_ a container unprivileged til the patches are merged upstream... you need CAP_SYS_ADMIN and to turn off seccomp and apparmor in the container for now. or the easiest way is to just run as privileged. The patches are outlined here: https://github.com/genuinetools/img#goals

I'm want to run img inside a VSTS agent container running in k8s and using

Linux agent-deployment-6d5f8c7fc8-56jbc 4.13.0-1016-azure #19-Ubuntu SMP Thu May 3 17:29:51 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

[jessfraz]

Yes you can do that, the easiest way is to run the container as privileged.
