modify layers
by Hendrik Haddorp 10 Jun '20

10 Jun '20

Hi, is there a way to modify the layers of an image? For example I would like to change some file attributes in an image without duplicating the data and not changing anything else in the structure of my image. I assume this can not be done with buildah but could it be done using some underlying libraries, like maybe https://github.com/containers/image ? thanks, Hendrik

Debugging performance on WSL2
by Dominic 07 Jun '20

07 Jun '20

Hello, I've been using podman and buildah for a while on native Ubuntu and it's been great. With the release of WSL2 I'm trying to start building containers on Windows, but I'm running into some performance issues. Running something like: buildah copy $container . /srv in my project root takes maybe a second or two on native linux and minutes on my WSL2 system. Windows task manager doesn't show high resource utilization from any particular process during this time. Any ideas on how I can debug this? -- Thank you, Dominic

Running buildah in OCP
by Dmitry Misharov 02 Jun '20

02 Jun '20

Hi, I was trying to build an image with the new registry.redhat.io/rhel8/buildah in OCP 4.3 and no luck. I read this article https://developers.redhat.com/blog/2019/08/14/best-practices-for-running-bu… but it seems it's not applicable for running buildah inside and OCP container. For example I cannot mount /dev/fuse or use overlay storage driver without mounting host directories. So is there a way to use buildah in OCP withoud cluster admin privileges? -- Dmitry Misharov Senior Quality Engineer, Red Hat Management QE Red Hat

run GUI app inside container
by /dev /local/ca 27 Apr '20

Can I install an Linux app in a buildah container, that when launched runs a GUI, and have that GUI displayed on the host OS/desktop? Any instructions/examples on how to do this would be helpful. For starters, the chrome browser for example. - Host OS: RHEL 8.x - buildah container: running latest RHEL UBI 8.x

running a container based on buildah image on docker host
by svinz82＠gmail.com 29 Jul '19

29 Jul '19

Hi, I build an image with Buildah and I can run a container with Podman based on this image without any problems. Now I need to run a container based on this image with Docker and it fails. I get this error: /usr/bin/docker-current: Error response from daemon: oci runtime error: container_linux.go:235: starting container process caused "exec: \"/bin/bash\": stat /bin/bash: no such file or directory". Are there some incompatibility with Docker or do I need to add something when I build my image to get this image running on a docker host? Bellow you can find the script I used to build my image: #!/bin/bash # start new container from scratch newcontainer=$(buildah from scratch) scratchmnt=$(buildah mount ${newcontainer}) # install the packages yum install --nogpgcheck --installroot ${scratchmnt} rpm bash coreutils ansible shadow-utils --releasever 7 --setopt=tsflags=nodocs --setopt=override_install_langs=en_US.utf8 -y # Clean up yum cache if [ -d "${scratchmnt}" ]; then rm -rf "${scratchmnt}"/var/cache/yum fi #create user and group buildah run ${newcontainer} groupadd -g 10000 somegroup buildah run ${newcontainer} useradd -u 10200 -g somegroup someuser # configure container label, entrypoint, default user and default working directory buildah config --label name=el7-ansible ${newcontainer} buildah config --cmd /bin/bash ${newcontainer} buildah config --user someuser ${newcontainer} buildah config --workingdir /etc/ansible ${newcontainer} # commit the image buildah unmount ${newcontainer} buildah commit ${newcontainer} el7-ansible #some cleanup buildah rm ${newcontainer}

Welcome!

Welcome to the Buildah mailing list! This list is for your questions, concerns or comments about the Buildah project (https://github.com/containers/buildah) The list will also be used by the maintainers when there are announcements of interest to the community. What is Buildah? Buildah is an Open Source project on GitHub that provides a command line tool which can be used to create a container image or a working container. The container images can be built from 'scratch', by using Buildah command line instructions, or by using an industry standard Dockerfile. Buildah can create and use both the Open Containers Initiative (OCI) or the traditional upstream Docker container image format. A container root file system can be mounted for manipulation and then the updated contents can be used to create a new image. Buildah also offers the ability to remove and rename containers and container images. Buildah has a web site (https://www.buildah.io) devoted to blogs and announcements for the project along with tutorials and slides from talks that the maintainers have made at a variety of conferences. Buildah has a sister project, Podman, which manages everything in the Kubernetes universe such a pods, containers, container images and container volumes. Podman has it's own website (https://www.podman.io) that you can check out for more information. Discussions about issues with Buildah on this list are welcomed, but to get those issues solved, you'll need to raise and issue in GitHub (https://github.com/containers/buildah.io/issues) We're happy to have join our community and look forward to your contributions!
