When playing a kube YAML file, it can be desirable to be able to build
an image on the fly. This is good for development of an image and YAML
files and somewhat mocks what compose does.

Add the --userns flag to podman pod create and keep

e2e test failures are rife with messages like:
Expected 1 to equal 0
These make me cry. They're anti-helpful, requiring the reader
to dive into the source code to figure out what those numbers
mean.
Solution: Go tests have a '.Should(Exit(NNN))' mechanism. I
don't know if it spits out a better diagnostic (I have no way
to run e2e tests on my laptop), but I have to fantasize that
it will, and given the state of our flakes I assume that at
least one test will fail and give me the opportunity to see
what the error message looks like.
THIS IS NOT REVIEWABLE CODE. There is no way for a human
to review it. Don't bother. Maybe look at a few random
ones for sanity. If you want to really review, here is
a reproducer of what I did:
cd test/e2e
! positive assertions. The second is the same as the first,
! with the addition of (unnecessary) parentheses because
! some invocations were written that way. The third is BeZero().
perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.To\(Equal\((\d+)\)\)/Expect($1).Should(Exit($2))/' *_test.go
perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.To\(\(Equal\((\d+)\)\)\)/Expect($1).Should(Exit($2))/' *_test.go
perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.To\(BeZero\(\)\)/Expect($1).Should(Exit(0))/' *_test.go
! Same as above, but handles three non-numeric exit codes
! in run_exit_test.go
perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.To\(Equal\((\S+)\)\)/Expect($1).Should(Exit($2))/' *_test.go
! negative assertions. Difference is the spelling of 'To(Not)',
! 'ToNot', and 'NotTo'. I assume those are all the same.
perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.To\(Not\(Equal\((0)\)\)\)/Expect($1).To(ExitWithError())/' *_test.go
perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.ToNot\(Equal\((0)\)\)/Expect($1).To(ExitWithError())/' *_test.go
perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.NotTo\(Equal\((0)\)\)/Expect($1).To(ExitWithError())/' *_test.go
! negative, old use of BeZero()
perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.ToNot\(BeZero\(\)\)/Expect($1).Should(ExitWithError())/' *_test.go
Run those on a clean copy of main branch (at the same branch
point as my PR, of course), then diff against a checked-out
copy of my PR. There should be no differences. Then all you
have to review is that my replacements above are sane.
UPDATE: nope, that's not enough, you also need to add gomega/gexec
to the files that don't have it:
perl -pi -e '$_ .= "$1/gexec\"\n" if m!^(.*/onsi/gomega)"!' $(grep -L gomega/gexec $(git log -1 --stat | awk '$1 ~ /test\/e2e\// { print $1}'))
UPDATE 2: hand-edit run_volume_test.go
UPDATE 3: sigh, add WaitWithDefaultTimeout() to a couple of places
UPDATE 4: skip a test due to bug #10935 (race condition)

Reason: to catch errors before they surface in RHEL.
One of the Ubuntus is specially crafted to run with cgroups v1
and runc. Although this isn't quite the same as RHEL, it's as
close as we can come in our CI environment, and I suspect it
would have caught #10234 (a regression).
Sorry, team.
Also: play kube limits test: skip on all rootless, not just
rootless+fedora. There was a complicated and unnecessary
check in there for Fedora.
Also: workaround for bug #10248, a spurious error message on
the first invocation of rootless podman on Ubuntu.Old

Add support for secretRef and secretKeyRef to allow env vars to be set
from a secret. As K8S secrets are dictionaries the secret value must
be a JSON dictionary compatible with the data field of a K8S secret
object. The keys must consist of alphanumeric characters, '-', '_'
or '.', and the values must be base64 encoded strings.

In K8S the pod creation fails if an env var reference a non existing
config map key. It can be marked as optional, but per default it is
mandatory. Podman on the other hand always treat such references as
optional.
Rework envVarsFrom() and envVarValue() to additionaly return an error
and add support for the optional attribute in configMapRef and
configMapKeyRef.

When kube play fails to create a volume, it should say which volume had
the problem so the user doesn't have to guess. For the following pod
spec:
apiVersion: v1
kind: Pod
metadata:
name: mypod
spec:
containers:
- name: myfrontend
image: nginx
volumeMounts:
- mountPath: "/var/www/html"
name: mypd
volumes:
- name: mypd
hostPath:
path: /var/blah
podman will now report:
Error: failed to create volume "mypd": error in parsing HostPath
in YAML: error checking path "/var/blah": stat /var/blah: no such
file or directory

In k8s a persistent volume claim (PVC) allow pods to define a volume
by referencing the name of a PVC. The PVC basically contains criterias
that k8s then use to select which storage source it will use for the
volume.
Podman only provide one abtracted storage, the named volumes, and
create them if they don't exists yet. So this patch simply use a
volume with the name of the PVC.

Replace the simple map of names to paths with a map of names to a struct
to allow passing more parameters. Also move the code to parse the volumes
to its own file to avoid making the playKubePod() function overly complex.

volume types.

Having play kube start the pod is not always appropriate, one might
for example like to have the pod running as a set of systemd services.
Add a `start` option to the command line and API to control if the pod
should be started or not; it defaults to true for backward
compatibility.

Followon to #7965 (mirror registry). mirror.gcr.io doesn't
cache all the images we need, and I can't find a way to
add to its cache, so let's just use quay.io for those
images that it can't serve.
Tools used:
skopeo copy --all docker://docker.io/library/alpine:3.10.2 \
docker://quay.io/libpod/alpine:3.10.2
...and also:
docker.io/library/alpine:3.2
docker.io/library/busybox:latest
docker.io/library/busybox:glibc
docker.io/library/busybox:1.30.1
docker.io/library/redis:alpine
docker.io/libpod/alpine-with-bogus-seccomp:label
docker.io/libpod/alpine-with-seccomp:label
docker.io/libpod/alpine_healthcheck:latest
docker.io/libpod/badhealthcheck:latest
Since most of those were new quay.io/libpod images, they required
going in through the quay.io GUI, image, settings, Make Public.

Previously, using an invalid image name would produce an error like
this:
Error: error encountered while bringing up pod test-pod-0: invalid reference format
This message didn't specify that there was an problem with an image
name, and it didn't specify which image name had a problem if there were
multiple. Now the error reads:

Currenly if a user specifies the name or ID of an external storage
container, we report an error to them.
buildah from scratch
working-container-2
podman rm working-container-2
Error: no container with name or ID working-container-2 found: no such container
Since the user specified the correct name and the container is in storage we
force them to specify --storage to remove it. This is a bad experience for the
user.
This change will just remove the container from storage. If the container
is known by libpod, it will remove the container from libpod as well.
The podman rm --storage option has been deprecated, and removed from docs.
Also cleaned documented options that are not available to podman-remote.
