Arnaud Porterie ba6adc5f46 Merge pull request #24646 from anusha-ragunathan/use-volume-plugins
Remove use of exec-root in plugins due to socket pathname limits.
2016-07-18 16:28:22 +00:00
Sebastiaan van Stijn 64a8317a5a Improve flag help consistency, and update docs
This adds the `--live-restore` option to the documentation.

Also synched usage description in the documentation
with the actual description, and re-phrased some
flag descriptions to be a bit more consistent.

Anusha Ragunathan 21ecd5a93d Remove use of exec-root in plugins due to socket pathname limits.
Unix sockets are limited to 108 bytes. As a result, we need to be
careful in not using exec-root as the parent directory for pluginID
(which is already 64 bytes), since it can result in socket path names
longer than 108 bytes. Use /tmp instead. Before this change, setting:
- dockerd --exec-root=/go/src/github.com/do passes
- dockerd --exec-root=/go/src/github.com/doc fails
After this change, there's no failure.

Also, write a volume plugins test to verify that the plugins socket
responds.

Michael Crosby a894aec8d8 Add --oom-score-adjust to daemon
This adds an `--oom-score-adjust` flag to the daemon so that the value
provided can be set for the docker daemon's process.  The default value
for the flag is -500.  This will allow the docker daemon to have a
less chance of being killed before containers do.  The default value for
processes is 0 with a min/max of -1000/1000.

-500 is a good middle ground because it is less than the default for
most processes and still not -1000 which basically means never kill this
process in an OOM condition on the host machine.  The only processes on
my machine that have a score less than -500 are dbus at -900 and sshd
and xfce( my window manager ) at -1000.  I don't think docker should be
set lower, by default, than dbus or sshd so that is why I chose -500.

Brian Goff dfd9187305 Implement plugin restore after daemon restart
This ensures that:

- The in-memory plugin store is populated with all the plugins
- Plugins which were active before daemon restart are active after.
  This utilizes the liverestore feature when available, otherwise it
  manually starts the plugin.

Tibor Vass f37117045c plugins: experimental support for new plugin management
This patch introduces a new experimental engine-level plugin management
with a new API and command line. Plugins can be distributed via a Docker
registry, and their lifecycle is managed by the engine.
This makes plugins a first-class construct.

For more background, have a look at issue #20363.

Documentation is in a separate commit. If you want to understand how the
new plugin system works, you can start by reading the documentation.

Note: backwards compatibility with existing plugins is maintained,
albeit they won't benefit from the advantages of the new system.

Tonis Tiigi 534a90a993 Add Swarm management backend
As described in our ROADMAP.md, introduce new Swarm management API
endpoints relying on swarmkit to deploy services. It currently vendors
docker/engine-api changes.

This PR is fully backward compatible (joining a Swarm is an optional
feature of the Engine, and existing commands are not impacted).

Michael Crosby 3020081e94 Merge pull request #23213 from crosbymichael/restore-option
Add --live-restore flag
2016-06-13 20:57:19 -07:00
Michael Crosby d705dab1b1 Add --live-restore flag
This flags enables full support of daemonless containers in docker.  It
ensures that docker does not stop containers on shutdown or restore and
properly reconnects to the container when restarted.

This is not the default because of backwards compat but should be the
desired outcome for people running containers in prod.

Jhon Honce 55a367d2fe Ignore SIGPIPE events, resolves #19728
Using golang 1.6, is it now possible to ignore SIGPIPE events on
stdout/stderr.  Previous versions of the golang library cached 10
events and then killed the process receiving the events.

systemd-journald sends SIGPIPE events when jounald is restarted and
the target of the unit file writes to stdout/stderr. Docker logs to stdout/stderr.

This patch silently ignores all SIGPIPE events.
