neutron failed to deploy in ubuntu binary

I believe this is fixed with using the shared flag in systemd. I believe Sam has a patch to modify the docs to resolve this problem.

Yes, I saw that patchset today

Thank you for your reply.

Hi Steven, how this fix problem in ubuntu where there is no systemd? I cherry-pick Sam's change. it make no difference for me. :(

Try to run the container manually
<pre>
docker start neutron_dhcp_agent
Error response from daemon: Cannot start container 73f4ec8885377419c1694ab77dea494c1f23a88cf4bc300a87aa0304ff94b135: Path /run/netns is mounted on /run but it is not a shared mount.
Error: failed to start containers: neutron_dhcp_agent
</pre>

sudo grep shared /proc/self/mountinfo
342 335 0:17 / /run rw,relatime shared:1 - tmpfs none rw
163 342 0:4 / /run/docker/netns/default rw shared:2 - nsfs nsfs rw

OK, I found a workaround for my problem. Before running deployment. I should run this command first.

 sudo mkdir -p /run/netns && sudo mount -o rw,relatime -t tmpfs tmpfs /run/netns && sudo mount --make-rshared /run

@Sam Yaple, this seems more reliable than simply run "mount --make-shared /run". do you think it is a good idea to incorporate this into the ubuntu playbook? Do you want me to upate the document?

OK, my apology. My way of doing thing is not stable either. Sometimes work, sometimes not.

One small comment: I'm using
- Ubuntu source
- All-in-one
and I also have this problem.
