One of the great things about FreeBSD is the poudriere tool. With it, you can create your own set of customized packages for installation on your server. Today, I will be installing packages in a FreeBSD 9.2 jail. Although I am installing in a jail, the same steps apply to any FreeBSD 9.2 host.

In this post, I will cover how to deliver the packages produced by poudriere. I have already written about building custom package with poudriere. In this post, I’ll show you how to deliver those packages over http (via nginx) and how to install them.

I will start by configuring nginx to deliver

I will continue by configuring the empty system I created using ezjail.

nginx deliver

These steps are carried out on your poudriere server.

I installed nginx with this command:

pkg install nginx

My nginx file looks like this:

worker_processes  1;

events {
    worker_connections  1024;
}


http {
    include       mime.types;
    default_type  application/octet-stream;

    sendfile        on;
    keepalive_timeout  65;

    server {
        listen       10.10.0.5:80;
        server_name  slocum.example.org;

         root /usr/local/www/nginx-default/;

        location /logs/ {
            root      /poudriere/data/;
            autoindex on;
            index     index.html index.htm;
        }

        location /packages/ {
            root      /poudriere/data;
            autoindex on;
            index     index.html index.htm;
        }

        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   /usr/local/www/nginx-dist;
        }
    }

}

The listen directive specifies an IP address because this host has multiple. The location directives seen above point to pathnames determined when setting up poudriere. You can see how I did that in my previous post.

You should enable ngnix by adding this to /etc/rc.conf:

nginx_enable="YES"

Then you can start ngnix with this command:

# service nginx start
Performing sanity check on nginx configuration:
nginx: the configuration file /usr/local/etc/nginx/nginx.conf syntax is ok
nginx: configuration file /usr/local/etc/nginx/nginx.conf test is successful
Starting nginx.

Now you should be able to view your build and your packages using the /log and /packages directories in your browser.

/etc/resolv.conf

In my newly created jail, there is nothing configured. My first step is setting up /etc/resolv.conf so DNS works. I added this to the file:

search example.com
nameserver 10.55.11.1

Your values must reflect your environment. Only you can decide what goes in your file.

Installing pkg

I am using FreeBSD 9.2, thus, I must install pkg by hand. I installed from the FreeBSD package servers with this command:

# pkg
The package management tool is not yet installed on your system.
Do you want to fetch and install it now? [y/N]: y
Bootstrapping pkg please wait
_http._tcp.pkg.FreeBSD.org
Installing pkg-1.2.7... done
If you are upgrading from the old package format, first run:

  # pkg2ng
Usage: pkg [-v] [-d] [-l] [-N] [-j |-c ] [-C ] [-R ]  []

Global options supported:
	-d             Increment debug level
	-j             Execute pkg(8) inside a jail(8)
	-c             Execute pkg(8) inside a chroot(8)

	-v             Display pkg(8) version
	-N             Test if pkg(8) is activated and avoid auto-activation

Configuring pkgng

The previous step installed /usr/local/etc/pkg.conf, but the contents are not needed for what we are going to do. So I removed that file.

On FreeBSD 9.2, you must set this value in /etc/make.conf to ensure that the new pkg is used, as opposed to the older commands:

WITH_PKGNG=             yes

I then specified our custom FreeBSD repository by first issuing this command:

mkdir /etc/pkg

and then creating /etc/pkg/FreeBSD.conf with this contents:

FreeBSD: {
   url: "pkg+http://slocum.example.org/packages/releng_9_2-HEAD-bacula",
   mirror_type: "srv",
   signature_type: "none",
   fingerprints: "/usr/share/keys/pkg",
   enabled: true
}

where slocum.example.org is the server which hosts your custom packages.

Installing the packages

Now you should be able to do this:

# pkg upgrade
Updating repository catalogue
digests.txz                                   100% 1188     1.2KB/s   1.2KB/s   00:00    
packagesite.txz                               100% 8920     8.7KB/s   8.7KB/s   00:00    
Incremental update completed, 18 packages processed:
18 packages updated, 0 removed and 0 added.
Nothing to do

An install looks like this:

# pkg install bash
Updating repository catalogue
The following 1 packages will be installed:

	Installing bash: 4.3.0_1

The installation will require 6 MB more space

0 B to be downloaded

Proceed with installing packages [y/N]: y
Checking integrity... done
[1/1] Installing bash-4.3.0_1...Updating /etc/shells
 done

If you install a package, all dependencies will also be installed. For example:

 # pkg install joe
Updating repository catalogue
digests.txz                                 100% 1292     1.3KB/s   1.3KB/s   00:00    
packagesite.txz                             100% 9708     9.5KB/s   9.5KB/s   00:00    
Incremental update completed, 20 packages processed:
0 packages updated, 0 removed and 2 added.
The following 2 packages will be installed:

	Installing aspell: 0.60.6.1_4
	Installing joe: 3.7_2,1

The installation will require 6 MB more space

1 MB to be downloaded

Proceed with installing packages [y/N]: y
aspell-0.60.6.1_4.txz                       100%  794KB 793.7KB/s 793.7KB/s   00:00    
joe-3.7_2,1.txz                             100%  315KB 315.3KB/s 315.3KB/s   00:00    
Checking integrity... done
[1/2] Installing aspell-0.60.6.1_4... done
[2/2] Installing joe-3.7_2,1... done

It’s fantastic.

Hope this helps.
