Polis DigiFinland Tools

Set of deploy scripts, settings files, custom patches, translations and utilities for running Polis experiment deployments for DigiFinland.

Initialization

1. Clone this repository.

   git clone git@github.com:polis-digifinland-tools/polis-digifinland-tools.git
   

   Optionally, set autocrlf if you encounter issues with line endings:

   git config --global core.autocrlf true
   

2. Add polis.local entry to your local DNS or hosts file:

   127.0.0.1 	polis.local
   

3. Copy digifinland-example.env to a new file called digifinland-dev.env and edit variables to match your environment.

Quickstart to get local environment up with Docker Compose

1. Patch Polis codebase:

   ./scripts/patch-polis-codebase.sh
   

2. Edit env variables in digifinland-dev.env file.

3. Build and start containers with Docker Compose:

   ./scripts/docker-compose_build-and-deploy.sh dev
   

4. Browse to https://polis.local

Database setup

Container

Docker Compose deployment uses Postgres service defined in docker-compose-digifinland.yml. Default database initialization & migration SQL scripts are run on the first startup.

Database on host for minikube (optional)

If you like to use minikube and skaffold for testing Kubernetes deployment locally, either install database on your host or create a new StatefulSet deployment running database container based on polis/server/Dockerfile-db. To use database from host, install Postgres 13.7 and use a suitable test DB dump. Note that newer Postgres versions are not supported by Polis yet. Example configurations assume that database service is running at host.docker.internal:5432.

Patching Polis codebase

To patch Polis submodule with DigiFinland customizations and settings, run patch script before building images or running docker compose.

This fetches latest working Polis version from origin/edge branch and adds custom configs and patches.

./scripts/patch-polis-codebase.sh

Docker Compose

Setup nginx as local loadbalancer (optional)

By default, configuration uses nginx container in a way it is used in the original codebase.

You can also use nginx on your host and setup load balancing proxy with example site configurations provided in the nginx directory.

Run dev env with Docker Compose

After patching, build and start all containers. Script takes env identifier (dev) as argument.

./scripts/docker-compose_build-and-deploy.sh dev

Stop and remove containers

Takes env identifier (dev) as argument.

./scripts/docker-compose_stop.sh dev

Minikube & Skaffold

Kubernetes configuration files are in ./manifests directory. See skaffold.yaml for artifacts and build config.

Starts local Minikube cluster with metrics and ingress addons, and starts ingress tunnel:

./scripts/k8s_start-local-minikube.sh

Builds and deploys containers using Skaffold:

skaffold run

Alternatively, to use image pruning, you can run:

skaffold dev --no-prune=false --cache-artifacts=false

Building and pushing images

Builds and pushes images to artifact registry.

Example:

./scripts/docker_images-build-and-push.sh example.com/project/repository tag-name
