Podman compiling from source
This post is a draft.
Podman newset version in couple of quick steps
As the title says, if you need newest version of podman, you have to build from source. However, you don’t have to build all the necessary 3rd party elements from source (such as go)
1.0 Installation of go
wget https://go.dev/dl/go1.21.3.linux-amd64.tar.gz
when follow installtion from
2.0 conmon
download, chmod +x, rename and copy to usr local bin
wget https://github.com/containers/conmon/releases/download/v2.1.9/conmon.amd64
chmod +x conmon.amd64
mv conmon.amd64 conmon
sudo mv conmon /usr/local/bin
2.1 instal from source
git clone https://github.com/containers/conmon
cd conmon
export GOCACHE="$(mktemp -d)"
make PREFIX=/usr
sudo make podman PREFIX=/usr
3.0 runc / crun
i’ll be using crun, since it is newer, and recommended now
wget https://github.com/containers/crun/releases/download/1.12/crun-1.12-linux-amd64
chmod +x crun-1.12-linux-amd64
mv crun-1.12-linux-amd64 crun
sudo mv crun /usr/local/bin
4.0 add config files for podman
copy and paste command from the tutorial
5.x needed deps to build podman
for buildeps seccomp (only seccomp)
make
gcc
libbtrfs-dev
pkg-config
libseccomp-dev
libdevmapper-dev
libgpgme-dev
uidmap
(for systemd - socket activation)
libsystemd-dev
https://github.com/rootless-containers/slirp4netns/releases/download/v1.2.2/slirp4netns-x86_64
https://github.com/containers/fuse-overlayfs/releases/download/v1.13/fuse-overlayfs-x86_64 - for rootless
5.0 podman from source
clone podman repo then checkout to newest tag version (e.g. git checkout v4.7.1)
git clone https://github.com/containers/podman/
cd podman
make -j4 BUILDTAGS="seccomp systemd" PREFIX=/usr
sudo make install BUILDTAGS="seccomp systemd" PREFIX=/usr
next: enable socket service:
systemctl status --user podman.socket
systemctl enable --user podman.socket
systemctl start --user podman.socket
systemctl status --user podman.socket
do setup cni networking: (config jsons): https://podman.io/docs/installation#setup-cni-networking
Errors:
Error response from daemon: plugin type=“bridge” failed (add): failed to find plugin “bridge” in path [/usr/local/libexec/cni /usr/libexec/cni /usr/local/lib/cni /usr/lib/cni /opt/cni/bin] ➜ gitea sudo apt install c ➜ gitea sudo apt install containernetworking-plugins -y
for buildx support:
sudo apt install catatonit
and run this at the end:
export DOCKER_HOST=unix://$XDG_RUNTIME_DIR/podman/podman.sock

make BUILDTAGS="seccomp" PREFIX=/usr
sudo BUILDTAGS="seccomp" PREFIX=/usr make install
sudo make uninstall BUILDTAGS="seccomp systemd" PREFIX=/usr
podman another storage
put file in $HOME/.config/containers/storage.conf
https://raw.githubusercontent.com/containers/storage/main/storage.conf
podman and docker-compose, docker alias
For zsh, open ~/.zshrc and put:
alias docker=podman
export DOCKER_HOST=unix://$XDG_RUNTIME_DIR/podman/podman.sock
podman system service
podman 4.7.1 contains command for generating socket:
podman system service
however, it looks like it is removed in podman 4.8
they say it was deprecated in favor of quadlets:
https://github.com/containers/podman/discussions/20218
https://www.redhat.com/sysadmin/quadlet-podman
https://docs.podman.io/en/latest/markdown/podman-system-service.1.html - should be deprecated in docs
update: it is not removed just only not compiled with flag systemd
podman systemd confg files
