baude ba65301c95 podman-remote create|run
add the ability to create and run containers via the podman-remote
client.

we now create an intermediate layer from the the create/run cli flags.
the intermediate layer can be converted into a createconfig or into a
varlink struct.  Once transported, the varlink struct can be converted
back to an intermediate layer and then to a createconfig.

remote terminals are not supported yet.

rootless: use a single user namespace
simplify the rootless implementation to use a single user namespace
for all the running containers.

This makes the rootless implementation behave more like root Podman,
where each container is created in the host environment.

There are multiple advantages to it: 1) much simpler implementation as
there is only one namespace to join.  2) we can join namespaces owned
by different containers.  3) commands like ps won't be limited to what
container they can access as previously we either had access to the
storage from a new namespace or access to /proc when running from the
host.  4) rootless varlink works.  5) there are only two ways to enter
in a namespace, either by creating a new one if no containers are
running or joining the existing one from any container.

Containers created by older Podman versions must be restarted.

baude 5e86acd591 display logs for multiple containers at the same time
add the ability for users to specify more than one container at a time
while using podman logs.  If more than one container is being displayed,
podman will also prepend a shortened container id of the container on
the log line.

also, enabled the podman-remote logs command during the refactoring of
the above ability.

Merge pull request #2633 from edsantiago/default_default
Usage messages: deduplicate '(default true)' et al
2019-03-15 06:22:46 -07:00
Ed Santiago 8f82edbcb3 Usage messages: deduplicate '(default true)' et al
Remove hardcoded '(default: true)' strings from bool flags,
and '(default this-or-that)' from string flags.

First because it's unmaintainable duplication that would cause
confusion should someone ever change the default and not notice
the message.

Second, because cobra[1] already prints '(default XXXX)' for
all options with non-false non-nil default. So in each of
these cases, current podman help behavior is:

    $ podman login --help
    ...
       --tls-verify  Require HTTPS ... (default: true) (default true)

This PR eliminates that duplication.

 [1] actually spf13/pflag/flag.go

The only nontrivial one of these is start.go, where the default
for sigProxy depends on the --attach flag. Solution: change
the command-line default to false, and implement the new
conditional default in logic. Bonus: removed unnecessary
check, because now if sigProxy is set without --attach,
we can guarantee that it was done by the user. But please
pay close scrutiny to this particular section in case
there's something I missed.

Disable -t (type) when the type is implicit through the subcommand.

baude ca1e76ff63 Add event logging to libpod, even display to podman
In lipod, we now log major events that occurr.  These events
can be displayed using the `podman events` command. Each
event contains:

* Type (container, image, volume, pod...)
* Status (create, rm, stop, kill, ....)
* Timestamp in RFC3339Nano format
* Name (if applicable)
* Image (if applicable)

The format of the event and the varlink endpoint are to not
be considered stable until cockpit has done its enablement.
