Setup Ansible

To get started, follow the installation guide to setup ansible on your machine.

Setup Stack Orchestrator

This playbook will install Docker and Stack Orchestrator (laconic-so) on the machine if they aren't already present.

Run the following commands in the stack-orchestrator-setup directory.

On Local Host

To setup stack orchestrator and docker locally, execute the setup-laconic-so.yml Ansible playbook:

LANG=en_US.utf8 ansible-playbook setup-laconic-so.yml --user $USER -kK

On Remote Host

To run the playbook on a remote host:

• Create a new hosts.ini file:

  cp ../hosts.example.ini hosts.ini
  

• Edit the hosts.ini file to run the playbook on a remote machine:

  [deployment_host]
  <host_name> ansible_host=<target_ip> ansible_user=<ssh_user> ansible_ssh_common_args='-o ForwardAgent=yes'
  

  • Replace <host_name> with the alias of your choice
  • Replace <target_ip> with the IP address or hostname of the target machine
  • Replace <ssh_user> with the SSH username (e.g., dev, ubuntu)

• Verify that you are able to connect to the host using the following command

  ansible all -m ping -i hosts.ini -k
  
  # Expected output:
  
  # <host_name> | SUCCESS => {
  #  "ansible_facts": {
  #      "discovered_interpreter_python": "/usr/bin/python3.10"
  #  },
  #  "changed": false,
  #  "ping": "pong"
  # }
  

• Execute the setup-laconic-so.yml Ansible playbook for setting up stack orchestrator and docker on a remote machine:

  LANG=en_US.utf8 ansible-playbook setup-laconic-so.yml  -i hosts.ini  --extra-vars='{ "target_host": "deployment_host"}' --user $USER -kK
  

Verify Installation

• After the installation is complete, verify if $HOME/bin is already included in your PATH by running:

  echo $PATH | grep -q "$HOME/bin" && echo "$HOME/bin is already in PATH" || echo "$HOME/bin is not in PATH"
  

  If the command outputs "$HOME/bin is not in PATH", you'll need to add it to your PATH.

• To add $HOME/bin to your PATH, run the following command:

  export PATH="$HOME/bin:$PATH"
  

• To make this change permanent, add the following line to your shell configuration file (~/.bashrc or ~/.zshrc, depending on your shell):

  # For bash users
  echo 'export PATH="$HOME/bin:$PATH"' >> ~/.bashrc
  source ~/.bashrc
  
  # For zsh users
  echo 'export PATH="$HOME/bin:$PATH"' >> ~/.zshrc
  source ~/.zshrc
  

• Once the PATH is set, verify the installation by running the following commands:

  # Check version of docker
  docker --version
  
  # Check version of docker compose
  docker compose version
  
  # Check version of Stack Orchestrator
  laconic-so version
