stack-orchestrator-setup

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

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