FreeBSD and Docker

[o***@hushmail.com]

Hi!

Attempting to install the Discourse discussion forum (https://github.com/discourse/discourse) on my DigitalOcean FreeBSD VPS. Discourse requires Docker, however nothing happens when I try `wget -qO- https://get.docker.com/ | sh` (https://github.com/discourse/discourse/blob/master/docs/INSTALL-cloud.md).

What am I doing wrong?

Thanks!

O.D.

did you try getting that file first?
as it is! maybe you could issue; wget https://get.docker.com/
once downloaded, try running the file; sh <filename>

Postgres, Redis and Ruby are available though, so I don't think it'd be impossible to get the RoR side of things working for Discourse.

True that. I managed to install the bundle but now during migration https://github.com/discourse/discourse/blob/master/db/migrate/20120921162512_add_meta_data_to_forum_threads.rb gives me:

== 20120921162512 AddMetaDataToForumThreads: migrating ========================
-- execute("CREATE EXTENSION IF NOT EXISTS hstore")
rake aborted!
StandardError: An error has occurred, this and all later migrations canceled:

PG::InvalidParameterValue: ERROR: version to install must be specified
: CREATE EXTENSION IF NOT EXISTS hstore/usr/home/www/myapp/vendor/bundle/ruby/2.2.0/gems/activerecord-4.1.10/lib/active_record/connection_adapters/postgresql/database_statements.rb:128:in `async_exec'

Docker or not, it's still odd that the migration should fail like this. I'm using PostgreSQL 9.4.

Hello again,

Thanks to Edho Arief from the OpenBSD mailinglists it appears I was simply missing the postgresql-contrib package.

Many thanks!

I'd go for a Linux environment if I was going to use Docker.

Aside from that, in general I break it down into steps first when trying to debug a problem. Remove the -q for a start to suppress warnings. The wget fails because of an invalid certificate on the site, try:

$ cd /tmp
$ wget --no-check-certificate https://get.docker.com -O temp.sh

That'll get you the install script in /tmp/temp.sh.

But the script deliberately looks for linux variants and will abort when you run it on freebsd... my understanding was Docker relies on Linux kernalisms fairly heavily (I don't know how far you get with linux compat in freebsd).

What are you doing wrong? You are trying to run docker on FreeBSD. Docker
is a containerization technology built for Linux. It uses LXC (which is
Linux Containers) for older Kernels or docker specific bits which are now
part of the modern Linux kernel 3.10+. Docker is basically FreeBSD Jails,
with a few more features and a lot more security issues. Stay away from
docker for a while till they fix all the security issues in it or look at
Rocket from the CoreOS team.

I have not looked into Discourse, but any application that requires Docker
is not worth using at this point. I am sure there must be a way to install
it without using Docker. You can get hints of how someone gets apps working
inside a Docker container by looking at the DockerFile if you go looking at
https://registry.hub.docker.com. This is a build file for a containers. If
you just cannot get Discourse working on FreeBSD, then by all means switch
to a Linux install instead. Make sure it is not centos as it will not have
the update Kernel drivers for better Docker support.

It's surely possible to run a "jail equivalent" of the Docker

Discourse is not exactly _requiring_ Docker - there has been
a prepackaged Docker "instance" of all the components you need
to run Discourse, not more, not less. It should be possible to
run Discourse the "traditional" way - using native FreeBSD
technology.

That is the final advice. :-)

Docker is for Linux, Jails is for FreeBSD. It's somewhat comparable
to a "pre-packaged VM image", more or less (probably less).

Oh, and doing things like

# wget http://getsomething.example.com | sudo bash

is definitely _not_ the way you want to install software on FreeBSD.
It rather seems to be a new Linuxism that has emerged during the
recent years. :-)

That's not a Linuxism; in fact, that's a "hipsterism". But that's another
question.

Well, I wouldn't say it's entirely impossible to get a Docker
implementation running on FreeBSD, but probably it won't work
1:1 with all imaginable software - I conclude this from the
concept of being able to run Linux applications on FreeBSD
using our Linux ABI, which works for _many_ applications, but
not for _all_ of them, especially not for those relying on
Linux kernel mechanisms that the ABI doesn't provide a proper
"translation" for. In those cases it's probably easier to use
native FreeBSD solutions: install the ported application into
a Jail. Yes, I know, Docker is much more than Jail in terms
of functionality...

Hmmmmm .... interesting read. One of the reasons I am migrating to *BSD
is the presumed absence of malevolent gov't involvement (*cough* SELinux
*cough*), I thought the BSD's were mostly/entirely free from such, no ?

Pretty sure that there aren't any NSA agents in deep cover who have
managed to become FreeBSD committers -- not that I have any way of
telling for sure of course.

Certainly FreeBSD relies on openness as the best guarantee that the OS
we're shipping is free from backdoors, trojans and the like. You've got
access to the source code and the build system so you can (in principle)
review everything you build and dyke out anything you don't like. Of
course, it's a tall order to expect everyone to have the skills to be
able to do that. Consequently, internally we're strongly advocating a
culture of routine code-review before making any commits, but
particularly to any sensitive areas of the kernel.

Cheers,

Matthew

To the contrary to OpenBSD which allegedly had that sort of trouble:

Hello everyone!

Thanks a lot for your input.

Any chance I could use something like overlayfs / zfs like the author claims?

https://meta.discourse.org/t/is-there-any-way-to-install-discourse-without-docker/16977

Do sign up and give your feedback. There used to be a FreeBSD thread @ meta.discourse.org but it just got deleted.

Many thanks!

I also inquired about docker a while back (last fall some time), mostly
out of curiosity. I notice it is only available for 10.1 & higher, &
only ZFS. Any polans for 9.3R, & maybe non-ZFS :-) ?
