====== Podman Install ======

**General Information**

Podman is an OCI (open container initiative) compliant container client and fully docker compatible.

Podman allows you to run and perform all of the docker-cli commands without running a docker daemon.

----

====== Install ======

Installing podman, the drop in replacement for docker cli.

===== Ubuntu 19.04 ====

Install the pre-req and add the PPA
<code bash>
sudo apt -y install software-properties-common
sudo add-apt-repository -y ppa:projectatomic/ppa
</code>

Install podman
<code bash>
sudo apt install podman
</code>

----

====== Configure ======

Add dockerhub as a default location to search for short named containers.
<code bash>
sudo vim /etc/containers/registries.conf

[registries.search]
registries = ["docker.io"]
</code>

----

====== Run ======

Since podman does not use a daemon, you can simply inspect/build/run containers and images.

Containers can also be run with non-root privileges.

The containers use storage at:
  * Running as normal user: ~/.local/containers/
  * Running as root/with sudo: /var/lib/containers/
