# Sharing Images
|
|
|
|
## Requirements
|
|
|
|
Have at least one image locally (run `podman image ls` to confirm).<br>
|
|
If you don't have images locally, run simply `podman pull httpd`.
|
|
|
|
## Objectives
|
|
|
|
1. Choose an image and create an archive out of it
|
|
2. Check the archive size. Is it different than the image size? If yes, what's the difference? If not, why?
|
|
3. Copy the generated archive to a remote host
|
|
4. Load the image
|
|
5. Verify it was loaded and exists on the remote host
|
|
|
|
## Solution
|
|
|
|
```
|
|
# Save image as an archive
|
|
podman save -o httpd.tar httpd
|
|
|
|
# Check archive and image sizes
|
|
du -sh httpd.tar # output: 143MB
|
|
podman image ls | grep httpd # output: 149MB
|
|
# The archive is obviously smaller than the image itself (6MB difference)
|
|
|
|
# Copy the archive to a remote host
|
|
rsync -azc httpd.tar USER@REMOTE_HOST_FQDN:/tmp/
|
|
|
|
# Load the image
|
|
podman load -i /tmp/httpd.tar
|
|
|
|
# Verify it exists on the system after loading
|
|
podman image ls
|
|
```
