Add: Update ploy publish to include systemd files

[c-badilla-manta]

Description of Changes

This change adds support for the creation of deb packages compatible with the systemd service manager.

To publish a deb package for systemd, you have to add the following new fields to the .ploy_publisher.ymlfile.

• systemd_files: a list of paths where the systemd .service file is located
• mnt_log_path (optional): This configuration is to declare where the service logs will be located. By default:/mnt/SERVICE_NAME
  Example:

systemd_files:
  - ../service-a/init/service-a.service
mnt_log_path: /mnt/service-a

Testing

Setup

1. Clone the ploy code in a ubuntu server
2. Run the following script to install the dependencies

gpg --keyserver hkp://keyserver.ubuntu.com --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 7D2BAF1CF37B13E2069D6956105BD0E739499BDB
curl -sSL https://get.rvm.io | bash -s stable
source ~/.zshrc
rvm pkg install openssl
rvm install 2.4.1 --with-openssl-dir=$HOME/.rvm/usr
bash --login
rvm use 2.4.1
gem install bundler:2.2.17
bundle install

3. Comment lines 14->16 in lib/ploy/publisher.rb file, to avoid publishing packages to S3.

Systemd

1. Configure the .ploy_publisher.yml file adding the two new options:

• systemd_files: a list of paths where the systemd .service file is located
• mnt_log_path (optional): This configuration is to declare where the service logs will be located
  Example:

upstart_files:
  - ../service-a/init/service-a
systemd_files:
  - ../service-a/init/service-a.service
mnt_log_path: /mnt/service-a

2. Execute the ploy publish command:

env RUBYLIB=./lib bundle exec bin/ploy publish PATH_TO_PLOY_PUBLISHER_YML

3. The deb package will be stored in the current path.
4. Copy the deb package to a ubuntu server with systemd service manager.
5. Install the package with the following command

sudo dpkg -i DEB_PACKAGE

6. Verify that the service is running:

systemctl status SERVICE_NAME

Upstart

1. Configure the .ploy_publisher.yml file without the two new options:

• systemd_files: a list of paths where the systemd .service file is located
• mnt_log_path (optional): This configuration is to declare where the service logs will be located
  Example:

upstart_files:
  - ../service-a/init/service-a

2. Execute the ploy publish command:

env RUBYLIB=./lib bundle exec bin/ploy publish PATH_TO_PLOY_PUBLISHER_YML

3. The deb package will be stored in the current path.
4. Copy the deb package to a ubuntu server with upstart service manager.
5. Install the package with the following command

sudo dpkg -i DEB_PACKAGE

6. Verify that the service is running:

service SERVICE_NAME status
