Hello,
We build our image based on the Dockerfile with something like
podman build -t sles15-sp6-v73 sles15-sp6-v73
and run it with
podman run -d -p 2022:22 ....sles15-sp6-v73
Building means that based on the Dockerfile we install the software
which should be come up on container start. This works all fine.
When we now add, install or configure something in addition in
the running container, all this gets lost on killing the container
and restart it again with 'podman run...'
Is it somehow possible to write this modified container to an image and
start this again, and not the image which was build with the Dockerfile?
Thanks
matthias

Hi Paul,
After reading the above page and the help of different podman sub
commands, I was able to clone (commit) our container. See the recording
of the various commands below. And the resulting container can be
started fine, SSH'ed into and the software (PostgreSQL server, our
application server, etc.) seems to run fine.
As always, new questions remain:
1)
Why is the old container not found by its image name
"localhost/sles15-sp6-v73:latest"?
2)
What are these 57 (!) repositories with the name "<none>"? Can I just
remove them with "podman rmi ...." based on their IMAGE ID?
3)
I expect that I could also clone (commit) "localhost/sles15-sp6-v73-000"
later to "localhost/sles15-sp6-v73-001", ... , true?
Thanks
matthias
