AutoBuilder Cluster Setup

autobuilder cluster setup

As root

• Install base OS with minimal target
• Add pokybuild user (uid=6000, or for older clusters 1006)
• Add pokybuild user to "users" group (gid 100) [if "users" group does not exist, create it]
• If a "kvm" group does not exist, add it to /etc/group and ensure /dev/kvm gid is set to "kvm" and is mode 660. Add pokybuild user to group "kvm" group
• Install the requirements from http://www.yoctoproject.org/docs/current/yocto-project-qs/yocto-project-qs.html
• git clone --single-branch http://git.yoctoproject.org/git/poky /root/poky (in /root for historical reasons, should change in the future)
• Install http://downloads.yoctoproject.org/releases/yocto/yocto-{latest release}/toolchain/x86_64/poky-glibc-x86_64-core-image-sato-core2-64-toolchain-{relver}.sh to /opt/poky
• Add startup scripts to create tap devs and start vncserver, in /etc/rc.local, /etc/init.d/boot.local, or as systemd unit files, should perform the following
  • cd /root/poky/scripts/; ./runqemu-gen-tapdevs 6000 100 32 /opt/poky/sysroots/x86_64-pokysdk-linux/
  • /bin/su - pokybuild -c "/usr/bin/vncserver"
• Disable or edit firewall rules to allow all connections to the tap devices. This allows sanity tests to connect to booted images.
• Install nfs-utils or nfs-common, add Domain to /etc/idmapd.conf, fstab entry, mount NAS

As pokybuild

• Set up buildset-config, either:
  • Add ssh key to clone production yocto-autobuilder
  • git clone http://git.yoctoproject.org/git/yocto-autobuilder && cd yocto-autobuilder && git remote add prod git@git.yoctoproject.org:yocto-autobuilder-production && git fetch prod && git checkout -b yoctoio prod/yoctoio
• or:
  • edit one of the several examples included in repo e.g. cp -r buildset-config.controller buildset-config

• update config/autobuilder.conf and yocto-worker/buildbot.tac
• Start the worker
  • touch ~/yocto-autobuilder/.setupdone
  • . yocto-autobuilder-setup
  • ./yocto-start-autobuilder worker
