Bootstrapping fails - trying to install postgress in /shared?

Hi, I’ve successfully got docker up and running on a Centos 7 VM, and am following the instructions at

The server is a clean install, minimal install with updates applied via yum.

Everything seems to work fine until I get to the bootstrap section, then this piece of ugliness shows up:

[root@docker01 discourse]# ./launcher bootstrap app
which: no in (/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin)
cd /pups && git pull && /pups/bin/pups --stdin
   ee8fdfb..4203610  master     -> origin/master

Location of failure: /pups/lib/pups/exec_command.rb:105:in `spawn'
exec failed with the params "mkdir -p /shared/postgres_run"

From what I’m reading, it seems to be attempting to install postgres in /shared - I’m new to docker so I assume it’s trying to install in that subdirectory of the docker jail. Sorry for using old-guy terminology - been running servers for years but never played with docker before.

Help greatfully received!


ok… not sure which fixed it, but I both a) rebooted, and b) made the shared/postgres directory

Now it’s bootstrapping, and seems to be ok.

Strange. Will update if any more problems, but I think I’m over the hump.
