This affects containers which use chroot (like archlinux:base) and thus pacman operations fail within the container (i.e. installing packages which execute post-install scripts). You can identify such issues if when building with podman you get errors like below during build: ... could not change the root directory (Operation not permitted) error: command failed to execute correctly ...
from the command line temporarily with --cap-add sys_chroot when you execute podman-build(1).
Set the driver according to the filesystem in use for the storage location (see containers-storage.conf(5) § STORAGE_TABLE).
Podman is able to run images built for different CPU architecture than the host using the Wikipedia:binfmt_misc system. To enable it, install qemu-user-static and qemu-user-static-binfmt.
get hostname resolution between containers running install podman-dnsname
If you have enabled buildkit in docker, the integration will not work.
Alpine Linux uses the musl libc implementation instead of the glibc libc implementation used by most Linux distributions. Because Arch Linux uses glibc, there are a number of functional differences between an Arch Linux host and an Alpine Linux container that can impact the performance and correctness of software. A list of these differences is documented in https://wiki.musl-libc.org/functional-differences-from-glibc.html.
use the full registry path in the Containerfile or Dockerfile.
The slirp4netns package is installed as a dependency to run Podman in a rootless environment.
If Podman uses the netavark network backend (see containers.conf(5)) then it is required to install aardvark-dns to have name resolution in rootless containers.
Install the podman package.
Additionally if you want to build container images look at Buildah.
/usr/share/containers/. You must copy necessary files to /etc/containers before editing
configure the network bridge interface used by Podman, see /etc/cni/net.d/87-podman.conflist
First, check the value of kernel.unprivileged_userns_clone by running: $ sysctl kernel.unprivileged_userns_clone
In order for users to run rootless Podman, a subuid(5) and subgid(5) configuration entry must exist for each user that wants to use it.
usermod --add-subuids 100000-165535 --add-subgids 100000-165535
