Self-hosting template for Koalati

Want to spin up your own instance of Koalati internally on your own server?

This repository contains everything you need to get started.

To learn more about Koalati's hosted service versus self-hosting, check out our Self-Hosting page.

Getting started

Before you get started, make sure that Docker is installed on your server/machine and that you are familiar with the way Docker works.

Then, follow the steps below:

  1. Clone this repository:
    git clone https://github.com/koalatiapp/hosting.git koalati
  2. Move into the newly created koalati directory:
    cd koalati
  3. Run the initialization script and follow instructions:
    bash initialize-environment.sh
  4. Start the server via docker-compose:
    docker-compose up -d

Once the server is up, you should be able to start using Koalati! Open https://localhost in your browser (or whichever other hostname you configured), and your own instance of Koalati should be up and running.

If you run into SSL certificate issues in your browser, check out the Troubleshooting section for an easy fix.

However, there's one last thing you should know about: self-hosted instances of Koalati are in invitation-only mode by default.

This means visitors cannot sign up unless they have been invited by an existing user.

To create that first user, use the create-user command:

docker-compose exec php bin/console app:security:create-user

And voilà! You now have your own instance of Koalati!

Updating your Koalati installation

Every once in a while, you'll want to update your self-hosted instance of Koalati to get the latest features, improvements and bugfixes.

To do that, first make sure your KOALATI_VERSION variable is set to latest in the .env file.

Then, make sure your hosting configs are up to date:

git pull

Finally, run the following commands to update:

docker-compose down --remove-orphans
docker-compose pull php
docker-compose pull caddy
docker-compose pull tools-service
docker-compose up -d

Self-hosting specific changes

To learn about self-hosting specific changes, check out our self-hosting documentation on Koalati's main repository.

Security

  • Invitation-only mode is enabled by default.
    • This is done as a security measure to prevent people discovering your internal Koalati instance and abusing it.
    • If your internal Koalati instance is protected via some other security measure (VPN, .htpasswd, etc.), you may disable this mode.

Troubleshooting

⚠️ Untrusted SSL certificate issues

If you have a TLS trust issues when running Koalati on your local machine, you can copy the self-signed certificate from Caddy and add it to the trusted certificates by running the command for your OS below from within the koalati directory.

You may have to restart your browser after running the command for this change to take effect.

Mac

docker cp $(docker compose ps -q caddy):/data/caddy/pki/authorities/local/root.crt /tmp/root.crt && sudo security add-trusted-cert -d -r trustRoot -k /Library/Keychains/System.keychain /tmp/root.crt

Linux

docker cp $(docker compose ps -q caddy):/data/caddy/pki/authorities/local/root.crt /usr/local/share/ca-certificates/root.crt && sudo update-ca-certificates

Windows

docker compose cp caddy:/data/caddy/pki/authorities/local/root.crt %TEMP%/root.crt && certutil -addstore -f "ROOT" %TEMP%/root.crt

⚠️ Docker Compose hangs without outputting anything

This is a common issue with docker-compose on VPS with limited resources.

First, run the following command:

cat /proc/sys/kernel/random/entropy_avail

If the output is less than 1000, that is almost certainly why it's hanging.

If that's the case for you, you can fix the issue by simply installing haveged on your VPS:

apt install haveged

Thanks to Phillip Elm's suggestion on StackOverflow for this fix.

Advanced configurations

If you feel adventurous, you can open and edit your .env and docker-compose.yaml files as you see fit to configure your Koalati environment to your liking.

For example, you could:

  • Disable Caddy's automatic HTTPS configuration by changing the SERVER_NAME variable.
  • Run Koalati on a different port by editing the docker-compose.yaml.
  • Use an external MySQL database instead of using the Docker-managed one.
  • Run the tools service externally on a more scalable infrastructure for improved performance.
