Podman Installation Instructions

Installing packaged versions of Podman

MacOS

Podman is a tool for running Linux containers. You can do this from a MacOS desktop as long as you have access to a linux box either running inside of a VM on the host, or available via the network. You need to install the remote client and then setup ssh connection information.

Remote Client

The Mac client is available through Homebrew:

brew install podman

Windows

Podman is a tool for running Linux containers. You can do this from a Windows desktop as long as you have access to a linux box either running inside of a VM on the host, or available via the network. You need to install the remote client and then setup ssh connection information in the podman-remote.conf file. Podman can also be run in the Windows Subsystem for Linux system, check out the link below to see a description of how this is done.

Linux Distributions

Amazon Linux 2

The Kubic project provides updated packages for CentOS 7 which can be used unmodified on Amazon Linux 2.

sudo curl -L -o /etc/yum.repos.d/devel:kubic:libcontainers:stable.repo https://download.opensuse.org/repositories/devel:/kubic:/libcontainers:/stable/CentOS_7/devel:kubic:libcontainers:stable.repo
sudo yum -y install yum-plugin-copr
sudo yum -y copr enable lsm5/container-selinux
sudo yum -y install podman

Arch Linux & Manjaro Linux

sudo pacman -S podman

If you have problems when running Podman in rootless mode follow the instructions here

CentOS

Podman is available in the default Extras repos for CentOS 7 and in the AppStream repo for CentOS 8 and Stream. Even though the available version often lags behind the latest upstream release, it’s still the preferable build for production environments.

sudo yum -y install podman

The Kubic project provides updated packages for CentOS 7, 8 and Stream. These packages haven’t been through the official Red Hat QA process and may not be preferable for production environments.

# CentOS 7
sudo curl -L -o /etc/yum.repos.d/devel:kubic:libcontainers:stable.repo https://download.opensuse.org/repositories/devel:/kubic:/libcontainers:/stable/CentOS_7/devel:kubic:libcontainers:stable.repo
sudo yum -y install podman

# CentOS 8
sudo dnf -y module disable container-tools
sudo dnf -y install 'dnf-command(copr)'
sudo dnf -y copr enable rhcontainerbot/container-selinux
sudo curl -L -o /etc/yum.repos.d/devel:kubic:libcontainers:stable.repo https://download.opensuse.org/repositories/devel:/kubic:/libcontainers:/stable/CentOS_8/devel:kubic:libcontainers:stable.repo
sudo dnf -y install podman
sudo dnf -y update

# CentOS Stream
sudo dnf -y module disable container-tools

sudo dnf -y install podman
sudo dnf -y update

Debian

The podman package is available in the Bullseye (testing) branch, which will be the next stable release (Debian 11) as well as Debian Unstable/Sid.

# Debian Testing/Bullseye or Unstable/Sid
sudo apt-get update
sudo apt-get -y install podman

If you would prefer newer (though not as well-tested) packages, the Kubic project provides packages for Debian 10 and newer. The packages in Kubic project repos are more frequently updated than the one in Debian’s official repositories, due to how Debian works. The build sources for the Kubic packages can be found here.

CAUTION: On Debian 11 and newer, including Debian Testing and Sid, we highly recommend you use Buildah, Podman and Skopeo ONLY from EITHER the Kubic repo OR the official Debian repos. Mixing and matching may lead to unpredictable situations including installation conflicts.

Building from scratch

Build and Run Dependencies

Required

Fedora, CentOS, RHEL, and related distributions you should try to run make package-install which will install dependencies, build the source, produce rpms for the current platform and install them in the end.

sudo yum install -y \
  btrfs-progs-devel \
  conmon \
  containernetworking-cni \
  device-mapper-devel \
  git \
  glib2-devel \
  glibc-devel \
  glibc-static \
  go \
  golang-github-cpuguy83-md2man \
  gpgme-devel \
  iptables \
  libassuan-devel \
  libgpg-error-devel \
  libseccomp-devel \
  libselinux-devel \
  make \
  pkgconfig \
  runc \
  containers-common

Debian, Ubuntu, and related distributions:

sudo apt-get install \
  btrfs-tools \
  git \
  golang-go \
  go-md2man \
  iptables \
  libassuan-dev \
  libbtrfs-dev \
  libc6-dev \
  libdevmapper-dev \
  libglib2.0-dev \
  libgpgme-dev \
  libgpg-error-dev \
  libprotobuf-dev \
  libprotobuf-c0-dev \
  libseccomp-dev \
  libselinux1-dev \
  libsystemd-dev \
  pkg-config \
  runc \
  uidmap

On openSUSE Leap 15.x and Tumbleweed:

sudo zypper -n in libseccomp-devel libgpgme-devel

On Manjaro (and maybe other Linux distributions):

Make sure that the Linux kernel supports user namespaces:

> zgrep CONFIG_USER_NS /proc/config.gz
CONFIG_USER_NS=y

If not, please update the kernel. For Manjaro Linux the instructions can be found here: https://wiki.manjaro.org/index.php/Manjaro_Kernels

After that enable user namespaces:

sudo sysctl kernel.unprivileged_userns_clone=1

To enable the user namespaces permanently:

echo 'kernel.unprivileged_userns_clone=1' > /etc/sysctl.d/userns.conf

Building missing dependencies

If any dependencies cannot be installed or are not sufficiently current, they have to be built from source. This will mainly affect Debian, Ubuntu, and related distributions, or RHEL where no subscription is active (e.g. Cloud VMs).

golang

Be careful to double-check that the version of golang is new enough (i.e. go version), version 1.12.x or higher is supported. If needed, golang kits are available at https://golang.org/dl/. Alternatively, go can be built from source as follows (it’s helpful to leave the system-go installed, to avoid having to bootstrap go:

export GOPATH=~/go
git clone https://go.googlesource.com/go $GOPATH
cd $GOPATH
git checkout tags/go1.12.17  # optional
cd src
./all.bash
export PATH=$GOPATH/bin:$PATH

conmon

The latest version of conmon is expected to be installed on the system. Conmon is used to monitor OCI Runtimes. To build from source, use the following:

git clone https://github.com/containers/conmon
cd conmon
export GOCACHE="$(mktemp -d)"
make
sudo make podman

runc

The latest version of runc is expected to be installed on the system. It is picked up as the default runtime by Podman. Version 1.0.0-rc4 is the minimal requirement, which is available in Ubuntu 18.04 already. To double-check, runc --version should produce at least spec: 1.0.1, otherwise build your own:

git clone https://github.com/opencontainers/runc.git $GOPATH/src/github.com/opencontainers/runc
cd $GOPATH/src/github.com/opencontainers/runc
make BUILDTAGS="selinux seccomp"
sudo cp runc /usr/bin/runc

CNI plugins

Setup CNI networking

A proper description of setting up CNI networking is given in the cni README.

A basic setup for CNI networking is done by default during the installation or make processes and no further configuration is needed to start using Podman.

Add configuration

sudo mkdir -p /etc/containers
sudo curl -L -o /etc/containers/registries.conf https://raw.githubusercontent.com/projectatomic/registries/master/registries.fedora
sudo curl -L -o /etc/containers/policy.json https://raw.githubusercontent.com/containers/skopeo/master/default-policy.json

Optional packages

Fedora, CentOS, RHEL, and related distributions:

(no optional packages)

Debian, Ubuntu, and related distributions:

apt-get install -y \
  libapparmor-dev

Get Source Code

First, ensure that the go version that is found first on the $PATH is higher than 1.12.x. Instruction above will help you compile newer version of Go if needed. Then we can build Podman:

git clone https://github.com/containers/podman/
cd podman
make BUILDTAGS="selinux seccomp"
sudo make install PREFIX=/usr

Build Tags

Otherwise, if you do not want to build Podman with seccomp or selinux support you can add BUILDTAGS="" when running make.

make BUILDTAGS=""
sudo make install

Podman supports optional build tags for compiling support of various features. To add build tags to the make option the BUILDTAGS variable must be set, for example:

make BUILDTAGS='seccomp apparmor'

Build Tag	Feature	Dependency
apparmor	apparmor support	libapparmor
exclude_graphdriver_btrfs	exclude btrfs	libbtrfs
exclude_graphdriver_devicemapper	exclude device-mapper	libdm
libdm_no_deferred_remove	exclude deferred removal in libdm	libdm
seccomp	syscall filtering	libseccomp
selinux	selinux process and mount labeling
systemd	journald logging	libsystemd

Note that Podman does not officially support device-mapper. Thus, the exclude_graphdriver_devicemapper tag is mandatory.

Vendoring - Dependency Management

This project is using go modules for dependency management. If the CI is complaining about a pull request leaving behind an unclean state, it is very likely right about it. After changing dependencies, make sure to run make vendor to synchronize the code with the go module and repopulate the ./vendor directory.

Static build

It is possible to build a statically linked binary of Podman by using the officially provided nix package and the derivation of it within this repository. The builds are completely reproducible and will create a x86_64/amd64 stripped ELF binary for glibc.

Nix

To build the binaries by locally installing the nix package manager:

curl -L https://nixos.org/nix/install | sh
git clone https://github.com/containers/podman.git && cd podman
nix build -f nix/
./result/bin/podman --version

Ansible

An Ansible Role is also available to automate the installation of the above statically linked binary on its supported OS:

sudo su -
mkdir -p ~/.ansible/roles
cd ~/.ansible/roles
git clone https://github.com/alvistack/ansible-role-podman.git podman
cd ~/.ansible/roles/podman
pip3 install --upgrade --ignore-installed --requirement requirements.txt
molecule converge
molecule verify

Configuration files

registries.conf

Man Page: registries.conf.5

/etc/containers/registries.conf

registries.conf is the configuration file which specifies which container registries should be consulted when completing image names which do not include a registry or domain portion.

Example from the Fedora `containers-common` package

cat /etc/containers/registries.conf
# This is a system-wide configuration file used to
# keep track of registries for various container backends.
# It adheres to TOML format and does not support recursive
# lists of registries.

# The default location for this configuration file is /etc/containers/registries.conf.

# The only valid categories are: 'registries.search', 'registries.insecure',
# and 'registries.block'.

[registries.search]
registries = ['docker.io', 'registry.fedoraproject.org', 'quay.io', 'registry.access.redhat.com', 'registry.centos.org']

# If you need to access insecure registries, add the registry's fully-qualified name.
# An insecure registry is one that does not have a valid SSL certificate or only does HTTP.
[registries.insecure]
registries = []


# If you need to block pull access from a registry, uncomment the section below
# and add the registries fully-qualified name.
#
[registries.block]
registries = []

mounts.conf

/usr/share/containers/mounts.conf and optionally /etc/containers/mounts.conf

The mounts.conf files specify volume mount directories that are automatically mounted inside containers when executing the podman run or podman build commands. Container process can then use this content. The volume mount content does not get committed to the final image.

Usually these directories are used for passing secrets or credentials required by the package software to access remote package repositories.

For example, a mounts.conf with the line “/usr/share/rhel/secrets:/run/secrets”, the content of /usr/share/rhel/secrets directory is mounted on /run/secrets inside the container. This mountpoint allows Red Hat Enterprise Linux subscriptions from the host to be used within the container.

Note this is not a volume mount. The content of the volumes is copied into container storage, not bind mounted directly from the host.

Example from the Fedora `containers-common` package:

cat /usr/share/containers/mounts.conf
/usr/share/rhel/secrets:/run/secrets

seccomp.json

/usr/share/containers/seccomp.json

seccomp.json contains the whitelist of seccomp rules to be allowed inside of containers. This file is usually provided by the containers-common package.

The link above takes you to the seccomp.json

policy.json

/etc/containers/policy.json

Man Page: policy.json.5

Example from the Fedora `containers-common` package:

cat /etc/containers/policy.json
{
    "default": [
        {
            "type": "insecureAcceptAnything"
        }
    ],
    "transports":
        {
            "docker-daemon":
                {
                    "": [{"type":"insecureAcceptAnything"}]
                }
        }
}
