This directory contains everything to build a deb package that bundles a Spring Boot app that starts a web server.

####

Executable scripts:

  create-new-project.sh - This script can be used to create a new deb package project similar to this project that uses a different name (than fs-spring-boot-kamal). Output will be placed inside 'out' directory.

  build.sh - This script builds the deb package. If the above script is used, go to the corresponding directory inside out directory to find a copy of this build.sh script.

####

To create a new deb package project that uses 'mycompany-myapp' as the name, run the following command:

  ./create-new-project.sh mycompany  mycompany-myapp

  The newly generated project files will be found inside the out directory.

####

To build, run the following command:

  ./build.sh

  Note that the Spring Boot application has not been bundled with this. You need to build it seperately and put it in the correct directory (run build.sh for further details).

####

To install the build deb package run the following commands replacing the package.deb with the correct name of the deb file.

  cp package.deb /tmp
  cd /tmp
  apt install ./package.deb

The above "apt install" will download dependencies if needed. Otherwise, dpkg command can just be used to install or upgrade the package:

  dpkg -i package.deb

After installing the package, update the configuration file /etc/fs-spring-boot-kamal/application.yaml .

Enable service to start at boot time:

  systemctl enable fs-spring-boot-kamal

Start service:

  systemctl start fs-spring-boot-kamal

View service log:

  journalctl -u fs-spring-boot-kamal -f

  (Press CTRL+C to terminate log viewing)

Access the service:

  http://server-ip-or-hostname:8085/

  (Instead of 8085, use the port configured in application.yaml file)
