Merge pull request #6851 from rhatdan/mount
Add podman image mount
2020-07-29 04:30:01 -04:00
Ed Santiago 409d07a181 System tests: add environment, volume tests
Tests for #7094, in which symlinks in a volume would
cause chown errors and nonrunnable containers.

Tests for environment variable precedence, now
include --env-host and proxy settings

Fix a bug caught by covscan in helpers.t ('source'
path would fail if path included spaces).

Fix podman-run man page: it was incorrect in stating
precedence between in-image environment and --env-host.

Fixes: #7099

Add podman image mount
There are many use cases where you want to just mount an image
without creating a container on it. For example you might want
to just examine the content in an image after you pull it for
security analysys.  Or you might want to just use the executables
on the image without running it in a container.

The image is mounted readonly since we do not want people changing
images.

Cleanup handling of podman mount/unmount
We should default to the user name unmount rather then the internal
name of umount.

Also User namespace was not being handled correctly. We want to inform
the user that if they do a mount when in rootless mode that they have
to be first in the podman unshare state.

Ashley Cui d419856009 Fix & add notes regarding problematic language in codebase
Podman is committed to inclusivity, a core value of open source. Historically, there have been technology terms that are problematic and divisive, and should be changed. We are currently taking time to audit our repository in order to eliminate such terminology, and replace it with more inclusive terms. We are starting where we can, with our own code, comments, and documentation. However, such terms may be used in dependencies, and must be used in our repositories at the current moment for compatibility. Podman will change these terms in our repo as soon as new and better terminology is available to us via our dependencies.

Joseph Gooch 0b1c1ef461 Implement --sdnotify cmdline option to control sd-notify behavior
--sdnotify container|conmon|ignore
With "conmon", we send the MAINPID, and clear the NOTIFY_SOCKET so the OCI
runtime doesn't pass it into the container. We also advertise "ready" when the
OCI runtime finishes to advertise the service as ready.

With "container", we send the MAINPID, and leave the NOTIFY_SOCKET so the OCI
runtime passes it into the container for initialization, and let the container advertise further metadata.
This is the default, which is closest to the behavior podman has done in the past.

The "ignore" option removes NOTIFY_SOCKET from the environment, so neither podman nor
any child processes will talk to systemd.

This removes the need for hardcoded CID and PID files in the command line, and
the PIDFile directive, as the pid is advertised directly through sd-notify.

Mark Stosberg 8d69f5178b docs: recommend alternatives to podman inspect
podman inspect is problematic because there can be naming clashes. Also,
it only inspects a couple of types of objects and the docs for it didn't
help discover that several more types could be inspected as well.

To address both concerns, we deprecate `podman inspect` and update the
docs to point to to the recommend alternatives.

podman: add new cgroup mode split
2020-06-29 10:53:41 -04:00
Matthew Heon 3601b96600 Allow empty host port in --publish flag
I didn't believe that this was actually legal, but it looks like
it is. And, unlike our previous understanding (host port being
empty means just use container port), empty host port actually
carries the same meaning as `--expose` + `--publish-all` (that
is, assign a random host port to the given container port). This
requires a significant rework of our port handling code to handle
this new case. I don't foresee this being commonly used, so I
optimized having a fixed port number as fast path, which this
random assignment code running after the main port handling code
only if necessary.

Fixes #6806

podman: add new cgroup mode split
When running under systemd there is no need to create yet another
cgroup for the container.

With conmon-delegated the current cgroup will be split in two sub
cgroups:

- supervisor
- container

The supervisor cgroup will hold conmon and the podman process, while
the container cgroup is used by the OCI runtime (using the cgroupfs
backend).

Ed Santiago c6090c290e Docs: consistency between man / --help
New functionality in hack/man-page-checker: start cross-
referencing the man page 'Synopsis' line against the
output of 'podman foo --help'. This is part 1, flag/option
consistency. Part 2 (arg consistency) is too big and will
have to wait for later.

flag/option consistency means: if 'podman foo --help'
includes the string '[flags]' in the Usage message,
make sure the man page includes '[*options*]' in its
Synopsis line, and vice-versa. This found several
inconsistencies, which I've fixed.

While doing this I realized that Cobra automatically
includes a 'Flags:' subsection in its --help output
for all subcommands that have defined flags. This
is great - it lets us cross-check against the
usage synopsis, and make sure that '[flags]' is
present or absent as needed, without fear of
human screwups. If a flag-less subcommand ever
gets extended with flags, but the developer forgets
to add '[flags]' and remove DisableFlagsInUseLine,
we now have a test that will catch that. (This,
too, caught two instances which I fixed).

I don't actually know if the new man-page-checker
functionality will work in CI: I vaguely recall that
it might run before 'make podman' does; and also
vaguely recall that some steps were taken to remedy
that.
