# Podman Hello World image
# New home
## Overview
The contents of the hello iamge have been moved to a dedicated repository:
https://github.com/containers/PodmanHello
This directory contains the Containerfile and bash script necessary to create the
"hello" podman image housed on quay.io under the Podman account in a public
repository. The image is public and can be pulled without credentials.
# Warning
Using this image is helpful to:
* Prove that basic Podman operations are working on the host.
* Shows that the image was pulled from the quay.io container registry.
* Container creation was successfully accomplished. (`podman ps -a`)
* The created container was able to stream output to your terminal.
## Directory Contents
The contents of this directory contain:
* ./Containerfile
* ./podman_hello_world.c
## Sample Usage
To simply run the image:
```
podman run quay.io/podman/hello
!... Hello Podman World ...!

```
To build the image yourself, copy the files from this directory into
a local directory and issue these commands:
```
podman build -t myhello .
podman run myhello
```
## Potential Issues:
The image runs as a rootless user with the UID set to `1000`.
If the /etc/subuid and /etch/subgid values are not set appropriately to run as a
rootless user on the host, an error like this might be raised:
```
Copying blob acab339ca1e8 done
ERRO[0002] Error while applying layer: ApplyLayer exit status 1 stdout: stderr: potentially insufficient UIDs or GIDs available in user namespace (requested 0:12 for /var/spool/mail): Check /etc/subuid and /etc/subgid: lchown /var/spool/mail: invalid argument

```

## THANKS!
Many Thanks to @afbjorklund for a great discussion during the
first revision of this container image that resulted in moving
from using bash to using C, and the ensuing changes to the
Containerfile.
Also many thanks to @mairin for the awesome ASCII art!
**DO NOT DELETE THIS DIRECTORY! Legacy tests depend on it.**
