Now that I’ve got CentOS 7 installed on my Raspberry Pi 3 I can make RPM builds available for this platform as well. The CentOS build has a few minor differences from the Debian/Raspbian builds and I took the opportunity to streamline the instructions a bit.
The Chef client is packaged with Omnibus, which builds the application and all of its runtime dependencies with the Omnibus-Toolchain. Omnibus is built with Ruby, so the instructions need to start with building Ruby. These instructions follow the Installing CentOS 7.6 on a Raspberry Pi 3, so the CentOS machine is ready for use.
There are several steps that need to be done before we get started. As the
root user update to ensure the latest packages are installed and install the prerequisites for building Ruby and Omnibus-Toolchain.
yum update yum install -y autoconf automake bison flex gcc gcc-c++ gdbm-devel gettext git kernel-devel libffi-devel libyaml-devel m4 make ncurses-devel openssl-devel patch readline-devel rpm-build wget zlib-devel
omnibus user for performing the builds.
Let’s add the
omnibus user to the
wheel group so they have permissions to manage the directories, this will make it easier to do the build with a single script rather than switching between the
usermod -aG wheel omnibus
visudo command and uncomment the following line:
%wheel ALL=(ALL) NOPASSWD: ALL
You can now
sudo su - omnibus and continue without changing users.
If you have previously-installed Chef and omnibus-toolchain packages (perhaps following these instructions), you’ll need to uninstall those and clear out the directories.
sudo systemctl stop chef-client sudo yum remove chef omnibus-toolchain -y sudo rm -rf /opt/chef /opt/omnibus-toolchain
echo 'gem: --no-document' >> ~/.gemrc
rbenv and add it to our
git clone https://github.com/rbenv/rbenv.git ~/.rbenv cd ~/.rbenv && src/configure && make -C src export PATH="$HOME/.rbenv/bin:$PATH" eval "$(rbenv init -)"
ruby-build plugin to make it easier to manage different Ruby versions.
mkdir plugins git clone https://github.com/rbenv/ruby-build.git "$(rbenv root)"/plugins/ruby-build rbenv install 2.6.3 rbenv global 2.6.3 eval "$(rbenv init -)"
Omnibus CentOS Raspberry Pi 3 Patch
CentOS provides packages for the Raspberry Pi 3 platform, but the arch is
armv7l. Omnibus does not have proper support for this yet, but the following patch has been submitted. You will need to patch your
lib/omnibus/packagers/rpm.rb in your
omnibus gem provided by bundler accordingly.
Now that Ruby is installed, let’s build and install the Omnibus-Toolchain as the
cd git clone https://github.com/chef/omnibus-toolchain.git cd omnibus-toolchain bundle install --without development --path=.bundle
lib/omnibus/packagers/rpm.rb patch to
Now you can build and install the RPM.
sudo mkdir /opt/omnibus-toolchain sudo mkdir /var/cache/omnibus sudo chown omnibus:omnibus -R /opt/omnibus-toolchain sudo chown omnibus:omnibus -R /var/cache/omnibus bundle exec omnibus build omnibus-toolchain -l internal sudo rm -rf /opt/omnibus-toolchain sudo rpm -Uvh ~/omnibus-toolchain/pkg/omnibus-toolchain*el7.armv7hl.rpm
omnibus-toolchain installed, we can reset our
PATH and build Chef as the
cd export PATH="/opt/omnibus-toolchain/bin:$PATH" wget https://github.com/chef/chef/archive/v14.12.9.tar.gz tar -xzf v14.12.9.tar.gz cd chef-14.12.9/omnibus/ bundle install --without development --path=.bundle
lib/omnibus/packagers/rpm.rb patch to
Now you can complete the Chef build.
sudo mkdir /opt/chef sudo chown omnibus:omnibus -R /opt/chef bundle exec omnibus build chef -l internal
This usually takes a 2 hours on this limited ARM machine.
Installing Chef 14.12.9
Once the builds have completed we can delete the working build directory.
sudo rm -rf /opt/chef
Now Chef 14.12.9 can be installed.
sudo rpm -Uvh ~/chef-14.12.9/omnibus/pkg/chef_14.12.9*el7.armv7hl.rpm
Using the new Chef build
From your workstation, you can now
knife bootstrap the machine with the ARM build on it and register it with your Chef Server. If you are working with a previously Chef-managed box, you can run
chef-client and the machine will continue to use its previous configuration.
