Podman
is an open-source, Linux-based tool designed to build, run and deploy containers.
Podman
is developed by the
CoreOs
team by keeping Docker in mind so that people familiar with
Docker
can quickly adopt podman.
Podman
containers are OCI(Open Containers Initiative) based and
similar
to
Docker
.
Podman
containers run as a
rootless
that provides additional
security
over docker containers.
All
docker
commands
which developers are familiar with also
exist
in
podman
.
If you have
existing
scripts that run on a
Docker
, all you need to do is create a docker
alias
for podman, and all your scripts should
work
.
(alias docker=podman)
In general,
docker
pulls
the images from
dockerhub
whereas
podman
pulls the images from the
RedHat
repo.
Podman
is very well
integrated
with
RedHat's openshift
enterprise application offering.
