# kamal-demo

How does Kamal work?

## Motivation

* It's cool.

* I want simplicity.

* How to go fast?

* Ideas from Pieter Levels (digital nomad with lots of startups)

  * Two login styles

    * Login via email, creates accounts, sends magic link,

      session token is nearly infinite

    * Oauth2 login (login with Gmail)

  * SQLite

* Django VPS

  * Login with magic links

  * Run SQLite db (good backups)

  * Easy deployment with something like Kamal

# My experience

1. Install kamal alias from instructions.

2. Missing docker.

3. Install Docker Desktop from docker.com

4. `kamal init`

5. Starting to configure in `config/deploy.yml`

6. Tried `kamal deploy`. Failed at registry login.

7. Created personal access token on Docker Hub.

8. Tried `kamal deploy` again. Timed out on server at 192.168.0.1. Shocker.

9. Tried `kamal build push`. Failed to find a Dockerfile.

10. Pulled Django Dockerfile from ChatGPT.

11. Tried `kamal build push`. Builder failed to find Dockerfile.

12. Commit `Dockerfile`.

13. Missing `requirements.txt`. Created simple one and committed.

14. `kamal build push` failed to deliver image to Docker Hub. Failed with: #16 ERROR: failed to push mblayman/kamal-demo:a3ef52a9f9b3d19f49f9814cb4ccb636328bdd1a: push access denied, repository does not exist or may require authorization: server message: insufficient_scope: authorization failed

15. In Docker Hub, make `kamal-demo` repository.

16. Still failed to push image to Docker Hub.

17. Install `kamal` using `gem install`.

18. `kamal build push` succeeded.

19. Reported https://github.com/basecamp/kamal/issues/919

# Kamal notes

* Traefik container - proxy that enables zero-downtime deploys

  (switches applications seemlessly when deploying)

* What's up with the permissions on directories? What should root-owned vs not?

* If using the top-level `volumes` key, where can we create the volume host directory?
