Walkthrough

This update introduces a comprehensive Ansible setup for configuring DigitalOcean Droplets, automating the installation of software and services, including SSH, NVM, Node.js, Yarn, Go, Docker, and a custom application. It features a sample inventory file, configuration templates for Docker, Go, and Yarn services, and a README guide detailing the execution of the playbook.

Changes

Files Change Summary
ansible/.gitignore Added inventory.ini to ignore list
ansible/example_inventory.ini Introduced sample configuration for hosting settings, including SSH, paths, user, and API tokens
ansible/main.yml Created playbook for setting up DigitalOcean Droplets, installing dependencies, and configuring services
ansible/readme.md Added instructions for running the Ansible playbook, including cloning the repository and setting up the inventory file
ansible/templates/docker.j2 Introduced PostgreSQL Docker container configuration template
ansible/templates/go.j2 Added a systemd unit file configuration template for a Go server
ansible/templates/server-config.j2 Introduced configuration settings template for different environments (dev, production)
ansible/templates/yarn.j2 Created a systemd unit file configuration template for Yarn service

Poem

In the land of code, where servers bloom,
Ansible scripts cast away the gloom.
With Droplets and Docker, all in sync,
Resolute thrives, though nodes may blink.
SSH keys and Yarn's new song,
In this realm, nothing goes wrong.
🐰✨

Tips

Chat

There are 3 ways to chat with CodeRabbit:

  • Review comments: Directly reply to a review comment made by CodeRabbit. Example:
    • I pushed a fix in commit <commit_id>.
    • Generate unit testing code for this file.
    • Open a follow-up GitHub issue for this discussion.
  • Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
    • @coderabbitai generate unit testing code for this file.
    • @coderabbitai modularize this function.
  • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
    • @coderabbitai generate interesting stats about this repository and render them as a table.
    • @coderabbitai show all the console.log statements in this repository.
    • @coderabbitai read src/utils.ts and generate unit testing code.
    • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
    • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

`10-10`: **Consider using environment variables for sensitive information.**

Storing API tokens directly in configuration files can be a security risk. Consider using environment variables instead.
[security]
```ini
digital_ocean_api_token="{{ lookup('env', 'DO_API_TOKEN') }}"

For better syntax highlighting and readability, please add the yaml language specifier to the fenced code block.

`92-161`: **Review the usage of variables and consider using `become_user`.**

A few suggestions:

1. Please define the `user_home` variable, as it is used in this task.
2. Note that the `ansible_user` variable is a built-in Ansible variable that represents the current user.
3. Consider using `become_user` instead of `become` to run commands as a specific user instead of root.

---

`250-255`: **Break down the long command for better readability.**

Consider breaking down the long command into multiple steps for better readability and maintainability. For example:

```yaml
- name: Load NVM
  shell: . {{ user_home }}/.nvm/nvm.sh
  args:
    executable: /bin/bash

- name: Use Node.js version 18
  shell: nvm use 18
  args:
    executable: /bin/bash

- name: Start frontend server in a detached screen session
  shell: screen -dmS yarn_session yarn start
  args:
    chdir: "{{ user_home }}/resolute/frontend"
    executable: /bin/bash

Good job using screen to run the command in a detached session.

2-56: Review the usage of variables and ensure that the required module is installed.

A few reminders and questions:

  1. Make sure to keep the digital_ocean_api_token secret and not commit it to the repository.
  2. Please define the user, ssh_key_name, and ssh_file_path variables, as they are used in this task.
  3. Ensure that the digital_ocean_droplet module is installed, as it is not a built-in Ansible module.

174-206: Define the go_version and user_home variables.

Please define the go_version and user_home variables, as they are used in this task.

223-249: LGTM!

The changes in this task look good to me. Good job using ansible_user to run commands as the current user.


257-288: LGTM!

The changes in this task look good to me. Good job using ansible_user to copy files as the current user and become to run Docker commands as root.


289-339: Define the user_home and path variables and consider using become_user.

Please define the user_home and path variables, as they are used in this task.

Also, consider using become_user instead of become to run Go commands as a specific user instead of root. For example:

- name: Run go get
  shell: go get ./...
  args:
    chdir: "{{ user_home }}/resolute/server"
  environment:
    HOME: "{{ user_home }}"
    PATH: "{{ path }}"
    GOPATH: "{{ user_home }}/go"
  become_user: "{{ ansible_user }}"

200-200: Remove trailing spaces.

Please remove the trailing spaces at the end of line 200 to fix the yamllint warning.

-          export GOROOT=/usr/local/go 
+          export GOROOT=/usr/local/go

Likely invalid or redundant comment.
