Preparing a build environment
To create builds you will need a build user (omnibus-build:omnibus-build in our example).
Preparing the build machine requires sudo access.
Ubuntu 12.04, 14.04
# Get the latest OS updates
sudo apt-get update
sudo apt-get upgrade
# Set up the firewall to only allow inbound SSH traffic
sudo apt-get install ufw
sudo ufw allow ssh
sudo ufw enable
# Check for SSH password logins, they should be disabled; The command below should return no results
grep '^[^#]*PasswordAuthentication' /etc/ssh/sshd_config
sudo service ssh reload
# Install dependencies
sudo apt-get install ruby1.9.1 ruby1.9.1-dev git build-essential cmake
sudo gem install --no-ri --no-rdoc bundler
# Create the build user
sudo adduser --gecos 'Omnibus Build' --disabled-password omnibus-build
# Create build directories for use by the build user
sudo mkdir -p /opt/gitlab /var/cache/omnibus
sudo chown omnibus-build:omnibus-build /opt/gitlab /var/cache/omnibus
Then, as the build user (omnibus-build):
# Login as omnibus-build user
sudo su - omnibus-build
# Clone the omnibus repo
git clone https://gitlab.com/gitlab-org/omnibus-gitlab.git
# Install gem dependencies for omnibus-ruby
cd omnibus-gitlab
bundle install --path .bundle --binstubs
# Do a build (and take a break from the computer)
bin/omnibus build project gitlab
Debian 7.4
the steps to build gitlab with omnibus on Debian 7.4 are equal to the ones to build on Ubuntu 12.04
Centos 6.5
# Update OS packages
sudo yum update
# Set up the firewall to only allow inbound SSH traffic
sudo lokkit -s ssh
# Check for SSH password logins; they should be disabled
grep '^[^#]*PasswordAuthentication' /etc/ssh/sshd_config
sudo service sshd reload
sudo yum groupinstall 'Development Tools'
# Install RedHat Software Collections to get Ruby 1.9.3
sudo yum install centos-release-SCL
sudo yum install ruby193 ruby193-ruby-devel
# Create the build user
sudo adduser -c 'Omnibus Build' omnibus-build
# Create build directories for use by the build user
sudo mkdir -p /opt/gitlab /var/cache/omnibus
sudo chown omnibus-build:omnibus-build /opt/gitlab /var/cache/omnibus
As the build user (omnibus-build):
# Enable Ruby 1.9.3 from Software Collections
echo 'exec scl enable ruby193 bash' >> .bash_profile
# Start a new login shell so we do not have to log out and in
# this one time
bash --login
# Clone the omnibus repo
git clone https://gitlab.com/gitlab-org/omnibus-gitlab.git
# Install gem dependencies for omnibus-ruby
cd omnibus-gitlab
bundle install --path .bundle --binstubs
# Do a build (and take a break from the computer)
bin/omnibus build project gitlab
Centos 7
As an administrator (or root):
yum update
sudo systemctl enable firewalld
sudo systemctl start firewalld
sudo firewall-cmd --list-all
# Check for SSH password logins; they should be disabled
grep '^[^#]*PasswordAuthentication' /etc/ssh/sshd_config
sudo systemctl reload sshd
sudo yum groupinstall 'Development Tools'
sudo yum install ruby ruby-devel cmake
sudo gem install bundler --no-ri --no-rdoc
# Create the build user
sudo adduser -c 'Omnibus Build' omnibus-build
# Create build directories for use by the build user
sudo mkdir -p /opt/gitlab /var/cache/omnibus
sudo chown omnibus-build:omnibus-build /opt/gitlab /var/cache/omnibus
As the build user (omnibus-build):
# Clone the omnibus repo
git clone https://gitlab.com/gitlab-org/omnibus-gitlab.git
# Install gem dependencies for omnibus-ruby
cd omnibus-gitlab
bundle install --path .bundle --binstubs
# Do a build (and take a break from the computer)
bin/omnibus build project gitlab
Usage
Build
You create a platform-specific package using the build project command:
$ bin/omnibus build project gitlab
The platform/architecture type of the package created will match the platform
where the build project command is invoked. So running this command on say a
MacBook Pro will generate a Mac OS X specific package. After the build
completes packages will be available in pkg/.
Clean
You can clean up all temporary files generated during the build process with
the clean command:
$ bin/omnibus clean
Adding the --purge purge option removes ALL files generated during the
build including the project install directory (/opt/gitlab) and
the package cache directory (/var/cache/omnibus/pkg):
$ bin/omnibus clean --purge
Help
Full help for the Omnibus command line interface can be accessed with the
help command:
$ bin/omnibus help
