Support for ruby 2.5 (Ubuntu 18.04)

[carlnordenfelt]

I'm trying to install the aws-codedeploy-agent on Ubuntu 18.04.
Ubuntu 18.04 comes with ruby 2.5.1

./install auto
I, [2018-05-02T15:39:46.472855 #4588]  INFO -- : Starting Ruby version check.

ruby --version
ruby 2.5.1p57 (2018-03-29 revision 63029) [x86_64-linux-gnu]

I followed the advice and create a symlink from ruby2.4 => ruby2.5 and re-ran installation:

ln -sf /usr/bin/ruby2.5 /usr/bin/ruby2.4

./install auto

At this point I rather desperately created a symlink between ruby2.5 and ruby2.3 without actually expecting it to work and as I suspected, no luck, same error.

ln -sf /usr/bin/ruby2.5 /usr/bin/ruby2.3

Any suggestions other than trying to install ruby2.4 via rvm which I have also tried and failed (don't have the logs from that attempt)?

I've trudged along a little bit with this and found that installing it from git appears to work on a clean Ubuntu 18.04 instance (AMI ID: ami-0b91bd72)

git clone https://github.com/aws/aws-codedeploy-agent.git
gem install bundler
gem install rake
cd aws-codedeploy-agent
bundle install
rake clean && rake

At least it builds and the tests passes.
I haven't actually started the agent because I have no configuration but the error message is promising

bin/codedeploy-agent start
error: The config file /opt/codedeploy-agent/conf/codedeployagent.yml does not exist or is not readable

Hi @carlnordenfelt,

I was able to get aws-codedeploy-agent running on Ubuntu Bionic working using your idea to install the gems using bundler. Here is a snippet of what I used. I haven't had a chance to do a codedeploy release yet, so I can't verify if all the Lifecycle hooks work fine.

# Install aws-codedeploy-agent and required gems
sudo apt-get install -y git
codedeploy_git_url='https://github.com/aws/aws-codedeploy-agent.git'
git clone "$codedeploy_git_url"
sudo gem install bundler
sudo mv aws-codedeploy-agent /opt/codedeploy-agent
cd /opt/codedeploy-agent
bundle install --system

# Setup permissions
sudo chown -R root.root /opt/codedeploy-agent
sudo chmod 644 /opt/codedeploy-agent/conf/codedeployagent.yml
sudo chmod 755 /opt/codedeploy-agent/init.d/codedeploy-agent
sudo chmod 644 /opt/codedeploy-agent/init.d/codedeploy-agent.service

# Create symlink to match ./install setup
sudo mkdir -p /etc/codedeploy-agent
sudo ln -s /opt/codedeploy-agent/conf /etc/codedeploy-agent/conf

# Move init scripts
sudo mv /opt/codedeploy-agent/init.d/codedeploy-agent /etc/init.d/codedeploy-agent
sudo mv /opt/codedeploy-agent/init.d/codedeploy-agent.service \
        /lib/systemd/system/codedeploy-agent.service

# Delete RHEL init info since this is for Ubuntu Bionic
sudo sed -i.bak '2,8d' /etc/init.d/codedeploy-agent && \
sudo rm -f /etc/init.d/codedeploy-agent.bak

# Enable init.d scripts to start at boot
sudo /etc/init.d/codedeploy-agent start && echo ''
sudo /usr/sbin/update-rc.d codedeploy-agent defaults
sudo /usr/sbin/update-rc.d codedeploy-agent enable

installing 2.4 via rvm only partially works, it fails later with

@salmonte your script worked perfect without any modifications for my Ubuntu 18.04 in AWS, even confirmed codedeploy was able to deploy to the instance afterward and the lifecycle hooks worked fine for me.

+1 on this request

Would anyone happened that errors are not shown in the deployments?

I've noticed that it only copies folders properly in the "files" section of the appspec.yml file. Files are incorrectly marked as folders, and unreadable.

After 2 days of testing I managed to make it work in a clean installation of Ubuntu 18 with rvm:

(sudo su)
gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 7D2BAF1CF37B13E2069D6956105BD0E739499BDB

\curl -sSL https://get.rvm.io | bash -s stable --ruby=2.3.0

echo 'source /usr/local/rvm/scripts/rvm' >> /etc/profile
echo 'source /usr/local/rvm/scripts/rvm' >> ~/.bashrc
exec $SHELL

ruby -v

gem install bundler

cd /opt
git clone https://github.com/aws/aws-codedeploy-agent.git codedeploy-agent
cd codedeploy-agent
bundle install
rake clean && rake

cp /opt/codedeploy-agent/init.d/codedeploy-agent /etc/init.d/
systemctl daemon-reload
systemctl start codedeploy-agent
systemctl enable codedeploy-agent

Another idea to get codedeploy-agent running on Ubuntu 18.04 (bionic):

# remove ruby 2.5/rake if installed
apt purge libruby ruby rake

# add repositories for xenial and xenial-updates
cat << EOF > /etc/apt/sources.list.d/xenial.list
deb http://archive.ubuntu.com/ubuntu/ xenial main
deb http://archive.ubuntu.com/ubuntu/ xenial-updates main
EOF

# priorise ruby/rake from xenial repository
cat << EOF > /etc/apt/preferences.d/ruby-xenial
Package: ruby
Pin: release v=16.04, l=Ubuntu
Pin-Priority: 1024

Package: rake
Pin: release v=16.04, l=Ubuntu
Pin-Priority: 1024
EOF

# install ruby and dependent packages
apt update
apt install ruby gdebi-core

# download and run codedeploy-agent installer
curl -o /tmp/codedeploy-installer https://aws-codedeploy-eu-west-1.s3.amazonaws.com/latest/install
chmod +x /tmp/codedeploy-installer
/tmp/codedeploy-installer auto

# delete installer script
rm -f /tmp/codedeploy-installer

# create systemd service file and enable it
mv /etc/init.d/codedeploy-agent.service /lib/systemd/system/codedeploy-agent.service
systemctl enable codedeploy-agent.service

This approach ensures that your system is receiving security updates for ruby, and this won't break anything (unless any of your applications require ruby >= 2.4). Also, this uses "official" stable releases of the AWS CodeDeploy agent.

Trying to setup the codedeploy-agent on a new 18.04 image using rodrigodev94's method, and the GPG server is returning connection timed out. Are there options to install it without needing to validate the keys? Or just confirmation that they key agent here isn't failing?

I created fake package (ruby2.3) and modify install script to workaround this issue:

# Ruby 2.5
sudo apt -y install ruby

# Ruby 2.3 (fake)
sudo apt -y install equivs
cd /tmp
equivs-control ruby2.3.control
perl -pi -e 's{^Package.*}{Package: ruby2.3}' ruby2.3.control
equivs-build ruby2.3.control
sudo dpkg -i ruby2.3_1.0_all.deb

# AWS CodeDeploy (us-east-1)
cd /tmp
wget https://aws-codedeploy-us-east-1.s3.amazonaws.com/latest/install
perl -pi -e "s{\\['2.4', '2.3', '2.2', '2.1', '2.0'\\]}{['2.5', '2.4', '2.3', '2.2', '2.1', '2.0']}" install
chmod 755 install
sudo ./install auto
