Addition of "--shm-size" to which size of /dev/shm is changed #16168

NIWAHideyuki · 2015-09-09T06:43:34Z

Addition of "--shm-size" to which size of /dev/shm is changed.
It relates to #2606 , #3505 and #4981.

fix #2606
fix #3505
fix #4981

Optional "--shm-size=" was added to the run sub-command.
The size of /dev/shm in the container can be changed when container is made.
Being able to specify is a numerical value that applies number, b, k, m, and g.
The default value is 64MB, when this option is not set.
It deals with both native and lxc drivers.

Looks like you need to run gofmt -s -w on your changes.
Also tests would be helpful.

bastih · 2015-09-11T09:21:12Z

Can we have this for docker build as well?

NIWAHideyuki · 2015-09-14T06:25:58Z

The size of shm is specified into "run and create".
I would like to try "build" next.

bastih · 2015-09-14T20:11:51Z

That would be awesome, we are currently using a custom build just to adjust shared memory during build time so we can run a program that needs more than the default amount of shared memory. Would be lovely to remove our hard-coded customizations.

lets do run and create for now, design lgtm moving to code review

I have to run a bash script in /dev/shm, but the server said 'Permission denied'.
When I use mount command, the result is:
shm on /dev/shm type tmpfs (rw,nosuid,nodev,noexec,relatime,size=1048576k)
My question is how to make /dev/shm have exec permission?
Thanks.

我修改了源代码，把NOEXEC去掉了，可以了。
建议下一版能提供NOEXEC的开关。

@lifubang - currently not possible - https://github.com/docker/docker/blob/master/daemon/container_operations_unix.go#L1048 - raise a separate issue if you can't find one already. Issues aren't a support request forum.

Remove old code for increase shm by runtime. Need to use docker v1.10.0 or newer for it (moby/moby#16168)

--shm-size=512m is not working for me as build args, either as run args.

I have tried lot's of way to set this value and I am completely stuck finding no way to configure it for using with gitlab.

I have started this issue, I post it here because it's a bit related to what I am trying to achieve : https://gitlab.com/gitlab-org/omnibus-gitlab/issues/1381
