Seneca-Specific SOP
This SOP is specific to the environment at Seneca CDOT since it refers to specific hosts, configurations, and tools. It is intended solely as a reference for the OSTEP team at CDOT, but the content may be useful to readers in other contexts.

Intro

This page covers how one can manage the various needed parts of a complete release process. This includes the other SOP pages containing file configurations and/or quick command line references for the following procedures:

Setting up environment
Building packages
Signing packages
Creating repositories
Composing images

Setting up environment

Follow the instructions on Chris's blog post: http://blog.chris.tylers.info/index.php?/archives/272-Acessing-the-armv6hl-Koji-Buildsystem.html

For Fedora 21 or later, you need to enable MD5 verification before using koji commands (according to here):

export OPENSSL_ENABLE_MD5_VERIFY=1

Building Packages

Koji-Follow Source Code and Configuration SOPs

http://zenit.senecac.on.ca/wiki/index.php/Koji_Follow

How-To-Run

ssh <your_username>@japan
sudo kojiadmin
screen -xr follow
python ~/koji-follow.py ~/koji-follow.conf > ~/logs/kfo.log 2> ~/logs/kfe.log

Post Commands

Repo analysis:

repoclosure --arch=armv6hl --arch=noarch --repofrompath=v6,http://japan.proximity.on.ca/repos/f20-build/latest/armv6hl/ -r v6 | tee /tmp/reporeport.log

Sign, Mash, and Rsync Together!

Prerequisites

Must setup passphraseless logins from root@japan to all users in the script
Must have a working mash configuration: See mash below
Must have a configured sigul user with access to the signing key
Make sure that any externally called scripts are in the correct locations

Running pidora-update.py

ssh japan
run as root: pidora-smr
script location /root/pidora-update/pidora-update.py

Usage: pidora-smr [options]

Options:
  -h, --help            show this help message and exit
  -i, --info            check machine status and configuration
  -a, --all             sign, mash, rsync
  -s, --sign            sign all packages in listed tag
  -m, --mash            start a mash run
  -r, --rsync           perform a rsync of the mash repos
  -f, --force           can force some options
  -l, --list-unsigned   list unsigned rpms
  --pidora=PIDORA       specify version of pidora = 18, 19
  --auto                enables logging and emails logs
  --koji-tag=KOJITAG    specify the koji tag to sign
  --email=email@senecacollege.ca
                        specify the email to send logs to
  --sigul-user=USER  specify the user for sigul
  --sigul-host=HOSTNAME
                        specify the host for sigul
  --mash-user=USER      specify the user for mash
  --mash-host=HOSTNAME
                        specify the host for mash
  --rsync-user=USER
                        specify the user for rsync
  --rsync-host=HOSTNAME
                        specify the host for rsync
  --log-dir=/var/log/pidora-smr/
                        specify a logging directory
  --log-file=output     specify a log file name

All the configurations in the script can be changed with the command line options

- Can change the user to access: sigul, mash, and rsync

- Can change the host which runs: sigul, mash, and rsync

- Can change which koji tag will be used for signing

- Can change the version of pidora to ssign, mash, rsync

Examples runs

Check which hosts can connect successfully
- Also shows default configurations

Get a list of unsigned packages
- Can check a single tag with --koji-tag=<tag-name>


pidora-smr --list-unsigned --pidora 18
pidora-smr --list-unsigned --pidora 19
pidora-smr --list-unsigned --pidora 20

Using the default configuration, start a sign, mash, rsync


pidora-smr --all --pidora 20

Change sigul user


pidora-smr --all --sigul-user=oatley --pidora 20

Run sign, mash, or sync separately, instead of together with the --all option


pidora-smr --sign --pidora 20
pidora-smr --mash --pidora 20
pidora-smr --rsync --pidora 20

Changing the configurations with command line options
- Sign using a different user, on a single koji tag


pidora-smr --sign --koji-tag=f18-updates-testing --pidora 20

Changing Default Configurations

Can view all default configurations with the following command:


pidora-smr --info

Modify the script with a text editor

- Change any of the variables listed below:

sigulhost = england.proximity.on.ca
siguluser = user

Mash Command Line Execution

/usr/local/bin/mashrun-pidora-18

Rsync to Pidora 18 Repositories

ssh pidorapr@pidora.ca
~/bin/rsync-japan

Composing Images

~~Before you can attempt to run a compose you should check to make sure that the following packages are installed:~~

~~anaconda~~

~~lorax~~

Because livemedia-tools is not stable software for creating pidora images we have a modified version of livemedia-creator that works well however this software is currently out of date, so we have decided to keep using this version of livemedia to produce future images. You can accessing our custom version of livemedia which is located on the host machine cal-7-2 within a chroot log onto the host machine iraq.proximity.on.ca then ssh into the compose node host machine cal-7-2.

ssh user@iraq.proximity.on.ca
ssh root@cal-7-2

Note if you restart or the node is shutdown you will need to bind mount /proc, /dev, /sys to f17v6/proc, f17v6/dev, f17v6/sys with the following command before you chroot.
mount -o bind /proc/ f17v6/proc
mount -o bind /dev/ f17v6/dev
mount -o bind /sys/ f17v6/sys

chroot into the armv6hl directory on the arm device.

chroot /root/f17v6

cd into the livemedia directory or where ever your kickstart file is located.

cd /livemedia/f20

Run the provided Livemedia-Creator command provided below to start the compose process.

Example Livemedia-Creator Command

livemedia-creator --make-disk --no-virt --image-only --keep-image --ks=pidora-f20.ks

Estimated time for compilation (15mins)

Example Kickstart File

Pidora 18 kickstart: http://zenit.senecac.on.ca/wiki/index.php/Pidora_kickstart

Package List File

Pidora 2014 Package List kickstart: http://zenit.senecac.on.ca/wiki/index.php/Pidora-2014-Packagelist-kickStart

command details

-h, --help For more info on commands
--make-disk Build a disk image
--no-virt Use Anaconda's image install instead of virt-install
--image-only Exit after creating disk image.
--ks KS Kickstart file defining the install.

Example Post Script Execution

You may have more than one %post section, which can be useful for cases where some post-installation scripts need to be run in the chroot and others that need access outside the chroot.

%post section is required to be closed with a corresponding %end

Post Section Options

command details

--nochroot
Allows you to specify commands that you would like to run outside of the chroot environment.

--interpreter /usr/bin/python
Allows you to specify a different scripting language, such as Python. Replace /usr/bin/python with the scripting language of your choice.

--erroronfail
If the post-installation script fails, this option will cause an error dialog to be displayed and will halt installation. The error message will direct you to where the cause of the failure is logged.

--log=

Example Post Installation Script "Creating/Modifying the fstab"

cat << EOF > /etc/fstab
LABEL="rootfs" / ext4 defaults,noatime 1 1
LABEL="boot" /boot vfat noauto,comment=systemd.automount 1 2
EOF

Preparing The Final Image

When you have a successful disk image ready the boot partition needs to be reformatted with a vfat filesystem type, the Raspberry Pi will only boot with a vfat boot partition. This can be done manually or by using the script provided below. The final image's rootfs also needs to be resized to minimize the size of file system, there is also a script provided to do this.

all the preparation scripts are located in /var/tmp/ directory along with the disk*.img file created by livemedia-creator.
~~Note these scripts work best if you copy them to your host machine and run them locally.~~ If you choose todo so you will need to scp the disk_image to your host machine.

Vfat Reformating Script

This script copies the boot partition to a temporary folder then reformat's that partition to vfat from ext4 it also removes the swap partition that is created by live-media-creator the swap partition is created during the firstboot process by the user.

Pidora 2014 Reformating Boot Partition Script: http://zenit.senecac.on.ca/wiki/index.php/Pidora-2014-Reformating-Boot-Script

Example usage

revfat disk_image.img

Checking The Partition FStype

After executing the revfat script your partition layout should look similar to this:

fdisk -l disk_image.img

         Device Boot      Start         End      Blocks   Id  System
diskz9llIY.img1   *        2048      104447       51200    c  W95 FAT32 (LBA)
diskz9llIY.img2          104448     6248447     3072000   83  Linux

Shrinking The Image

Script to take an SD card image (such as for a Raspberry Pi) with a dos disklabel and two partitions (boot vfat and rootfs extX), and shrink it so that the rootfs (2nd partition) is as short as possible plus a small free space allowance.

Pidora 2014 Shrink Script: http://zenit.senecac.on.ca/wiki/index.php/Pidora-2014-Shrink-Script
