Installation Instructions

System Requirements

Kernel Version Requirements

To run Buildah on Red Hat Enterprise Linux or CentOS, version 7.4 or higher is required. On other Linux distributions Buildah requires a kernel version of 4.0 or higher in order to support the OverlayFS filesystem. The kernel version can be checked with the 'uname -a' command.

runc Requirement

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. If Buildah is installed via a package manager such as yum, dnf or apt-get, runc will be installed as part of that process.

Package Installation

Buildah is available on several software repositories and can be installed via a package manager such as yum, dnf or apt-get on a number of Linux distributions.

Installation from GitHub

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 (Requires version 1.0 RC4 or higher.)
  • skopeo-containers

Fedora

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 on Fedora 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
  sudo make install
  buildah --help

RHEL, CentOS

In RHEL and CentOS 7, ensure that you are subscribed to rhel-7-server-rpms, rhel-7-server-extras-rpms, and rhel-7-server-optional-rpms, then run this command:

 yum -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

The build steps for Buildah on RHEL or CentOS are the same as Fedora, above.

Ubuntu

In Ubuntu zesty and xenial, you can use these commands:

  apt-get -y install software-properties-common
  add-apt-repository -y ppa:alexlarsson/flatpak
  add-apt-repository -y ppa:gophers/archive
  apt-add-repository -y ppa:projectatomic/ppa
  apt-get -y -qq update
  apt-get -y install bats btrfs-tools git libapparmor-dev libdevmapper-dev libglib2.0-dev libgpgme11-dev libostree-dev libseccomp-dev libselinux1-dev skopeo-containers go-md2man
  apt-get -y install golang-1.8

Then to install Buildah on Ubuntu 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
  PATH=/usr/lib/go-1.8/bin:$PATH make runc all TAGS="apparmor seccomp"
  sudo make install install.runc
  buildah --help

Debian

To install the required dependencies, you can use those commands, tested under Debian GNU/Linux amd64 9.3 (stretch):

gpg --recv-keys 0x018BA5AD9DF57A4448F0E6CF8BECF1637AD8C79D
gpg --export 0x018BA5AD9DF57A4448F0E6CF8BECF1637AD8C79D >> /usr/share/keyrings/projectatomic-ppa.gpg
echo 'deb [signed-by=/usr/share/keyrings/projectatomic-ppa.gpg] http://ppa.launchpad.net/projectatomic/ppa/ubuntu zesty main' > /etc/apt/sources.list.d/projectatomic-ppa.list
apt update
apt -y install -t stretch-backports libostree-dev golang
apt -y install bats btrfs-tools git libapparmor-dev libdevmapper-dev libglib2.0-dev libgpgme11-dev libseccomp-dev libselinux1-dev skopeo-containers go-md2man

The build steps on Debian are otherwise the same as Ubuntu, above.
