Nalin Dahyabhai 9049b6108c Test writing while selecting metadata formats
Add a test helper for examining image metadata and checking their types,
and add tests that use it to verify that after writing either Docker v2
or OCI v1 images, that the manifest and configuration blobs that we
stored for them successfully decode as the correct data types.

buildah - a tool for building OCI images

Go Report Card Travis

Note: this package is in alpha.

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
  • 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
  • device-mapper-devel
  • gpgme-devel
  • libassuan-devel
  • git
  • bzip2
  • go-md2man
  • skopeo-containers

In Fedora, you can use this command:

 dnf -y install \ 
    make \ 
    golang \ 
    bats \ 
    btrfs-progs-devel \ 
    device-mapper-devel \ 
    gpgme-devel \ 
    libassuan-devel \ 
    git \ 
    bzip2 \
    go-md2man \
    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
