./launcher start app hangs

support

Hi all,

this morning I switched form Mandrill to Mailgun. I followed the instructions in the blog post including Step 5. Spring Cleaning. All went fine and dandy until I tried to start the app with

./launcher start app

Problem: nothing happens. The shell hangs and my site is unreachable. If I Ctrl + c and run docker ps I see a discourse/discourse:1.0.17 image running, see below.

CONTAINER ID        IMAGE                        COMMAND                CREATED             STATUS              PORTS               NAMES
a3fce921de40        discourse/discourse:1.0.17   "/bin/sh -c 'md5sum    5 minutes ago       Up 5 minutes                            sick_goodall

Could the empty PORTS value be the problem? If so, how do I set it (I’m a Docker beginner)?

Any help is greatly appreciated as my site is currently down… :sadpanda:

command being "/bin/sh -c 'md5sum is a big concern … @mpalmer this really smells like it is this commit I am rolling it back for now:

https://github.com/discourse/discourse_docker/commit/21729b1bf284e487137c5c39957558834fc7bf9e

That change is reverted can you try rebuilding again?

Yes, that did it!

Thanks a million for the quick reply!

Just a followup to this, I’ve put together another PR that should fix this issue whilst still generating predicable MAC addresses.
