buildah - a tool which facilitates building OCI container images
Note: this package is in alpha, but is close to being feature-complete.
The buildah package provides a command line tool which can be used to
- create a working container, either from scratch or using an image as a starting point
- create an image, either from a working container or via the instructions in a Dockerfile
- images can be built in either the OCI image format or the traditional upstream docker image format
- mount a working container's root filesystem for manipulation
- unmount a working container's root filesystem
- use the updated contents of a container's root filesystem as a filesystem layer to create a new image
- delete a working container or an image
Installation notes
Prior to installing buildah, install the following packages on your linux distro:
- make
- golang (Requires version 1.8.1 or higher.)
- bats
- btrfs-progs-devel
- bzip2
- device-mapper-devel
- git
- go-md2man
- gpgme-devel
- glib2-devel
- libassuan-devel
- ostree-devel
- runc
- skopeo-containers
In Fedora, you can use this command:
dnf -y install \
make \
golang \
bats \
btrfs-progs-devel \
device-mapper-devel \
glib2-devel \
gpgme-devel \
libassuan-devel \
ostree-devel \
git \
bzip2 \
go-md2man \
runc \
skopeo-containers
Then to install buildah follow the steps in this example:
mkdir ~/buildah
cd ~/buildah
export GOPATH=`pwd`
git clone https://github.com/projectatomic/buildah ./src/github.com/projectatomic/buildah
cd ./src/github.com/projectatomic/buildah
make
make install
buildah --help
buildah uses runc to run commands when buildah run is used, or when buildah build-using-dockerfile
encounters a RUN instruction, so you'll also need to build and install a compatible version of
runc for buildah to call for those cases.
