How to deploy a Rails 7.1 app with Postgres and Kamal on a single server

I think you have looked at the tutorial from Mr. Heinemeier Hansson at least once or twice and have a similar setup.

rails new kamal_pg --css tailwind --skip-test --database=postgresql

cd kamal_pg

Things I believe

This is a collection of the things I believe about software development. I have worked for years building backend and data processing systems, so read the below within that context.

Clonando um sistema com rsync

Tava precisando migrar um sistema da Amazon para a Digital Ocean, e para clonar o sistema todo, usei rsync.

Conectei na máquina a ser migrada/clonada e mandei o seguinte comando:

sudo rsync --numeric-ids -aHAXSve ssh \
    --exclude={"/dev/*","/proc/*","/sys/*","/tmp/*","/run/*","/mnt/*","/media/*","/lost+found"} \
    / root@NewServer:/destination/directory

Debugging Gitlab CI jobs locally

You can find a bunch of articles about debugging Gitlab CI jobs locally. My top results from google:

• [SmallTips] Running GitLab CI Runner Locally | AkitaOnRails.com
• How to: Debug GitLab CI Builds Locally | Substrakt
• Debugging Gitlab CI pipelines locally – Campfire Code – Medium

But in all that articles the described way is to install Docker and gitlab-runner executable, run gitlab-runner exec docker JOB_NAME_FROM_GITLAB_CI_YML after that in your repo.

I don't like this approach because I want a simpler way to run appropriate gitlab-runner executable and don't

Retromods

What is a mod?

A mod is a set of code and assets that changes or augments the way a game is run. Examples of mods are:

• Music and sound packs that replace the original game music and sound.
• Graphics packs that replace the original game graphics.
• Level packs that change or replace the original game levels.
• Achievements that are awarded to the players when they complete tasks in the game.
