I’ve never had a problem running Discourse on CentOS in the past, but I’m suddenly unable to build it for some reason on a new CentOS 7.3 EC2 instance. While building, the errors begin with: I, [2017-03-02T05:29:38.051256 #13] INFO -- : > cd /var/www/discourse && chown -R discourse /var/www/discourse chown: cannot access '/var/www/discourse/app/assets/javascripts/discourse/helpers/max-usernames.js.es6': No such file or directory chown: cannot access '/var/www/discourse/lib/locale_file_walker.rb': No such file or directory …and the build fails with: FAILED -------------------- Pups::ExecError: cd /var/www/discourse && chown -R discourse /var/www/discourse failed with return # Location of failure: /pups/lib/pups/exec_command.rb:108:in `spawn' exec failed with the params {"cd"=>"$home", "hook"=>"web", "cmd"=>["gem update bundler", "chown -R discourse $home"]} Although not my usual approach, I followed the supported directions and continued to get identical errors. Here are the supported steps I’ve used on CentOS 7.3 with Docker 1.13.1 (build 092cba3) to reproduce the errors: mkdir /var/discourse git clone https://github.com/discourse/discourse_docker.git /var/discourse cd /var/discourse ./discourse-setup

Does Discourse on CentOS 7.3 help you at all?

[图片] codinghorror: As usual I suspect Docker issues. Notorious under Red Hat or clones. What filesystem is being used? docker info and all that. Hmm. All my Dockerfiles play well with CentOS, but maybe that’s because I develop against RHEL-type distros exclusively. [图片] mpalmer: Does Discourse on CentOS 7.3 help you at all? Maybe. This didn’t show up when I searched, but looks promising. What does “ftype” refer to? My dump and fsck values are both 0. cat /etc/fstab: UUID=ef6ba050-6cdc-416a-9380-c14304d0d206 / xfs defaults 0 0 This is the officially-supported AMI on AWS, by the way.

[图片] DanielMarquard: All my Dockerfiles play well with CentOS Do you ever do a chmod, chown, or similar in your Dockerfile? Most dockerfiles I’ve seen do absolutely everything as root, so they don’t hit this particular bug. [图片] DanielMarquard: What does “ftype” refer to? It’s a filesystem-creation-time option. According to the source post: [图片]Bootstrap fails on CentOS 7 On newer docker verision (1.13?) with docker info you can see support d_type = false So what does docker info have to say on your system?

[图片] mpalmer: Do you ever do a chmod, chown, or similar in your Dockerfile? Nope. [图片] mpalmer: So what does docker info have to say on your system? My docker info shows that d_type support is not enabled.

The best practice for using CentOS with EC2 is to use the officially-supported AMIs, so I’m not sure I have control over that. At least one of the issues in that post referenced a fix, but I’m running the latest Docker build from their official Yum repository, so I assume that either that fix isn’t apparent in my build or I’m running into an unresolved issue.

[图片] DanielMarquard: The best practice for using CentOS with EC2 is to use the officially-supported AMIs, so I’m not sure I have control over that. Time to report a bug against that AMI, then. [图片] DanielMarquard: At least one of the issues in that post included a fix The two issues linked to in this post were #9572 (filed in 2014 and not XFS specific) and #27358 which was acknowledged as not a Docker bug (and which led to the change to make it obvious in docker info that Supports d_type: false). [图片] DanielMarquard: I’m running into an unresolved issue This is not a bug in Docker. You are running a configuration that does not work, and absent some changes to the kernel, cannot work. Your options are as previously described in this post.

[图片] mpalmer: Time to report a bug against that AMI, then. I’ll reach out to my account manager at Amazon tomorrow. Thanks for the help.

I’ve already included solutions in my original post, anything stopped you from doing that?
