Running Kubernetes Cluster Locally

Install the following:

• Docker
• Helm
• Haskell Stack

Once you've enabled kubernetes, initialize helm by running

helm init

Follow the steps defined here to install the ingress controller. (Mandatory steps, as well as the helm steps will work fine.)

Next, pull the base image that you'll use to build the repo with the following:

docker pull fpco/stack-build:lts-13.9

The tag lts-13.9 should match the resolver in the stack.yaml, so adjust accordingly. Be aware, this will take a while... go get a coffee or something.

Build the application image with:

stack --docker setup
stack --docker install
docker build -t website:v1 .

The first time running the install will also take a while.

Edit the helm values file with:

cp charts/website/values.example.yaml charts/website/values.yaml

Edit the charts/website/values.yaml file with whatever credentials you see fit. Specifically the following:

• ingress.hosts
• admin.email
• admin.password
• postgresql.postgresqlUsername
• postgresql.postgresqlPassword
• postgresql.postgresqlDatabase

If you changed the name of the image when you built it, replace that too under image.repository and image.tag.

Add the following line into your /etc/hosts file. Replace the url with whatever you used for the ingress.hosts value.

127.0.0.1 structuredrants.local

Build the helm dependencies with:

helm dependencies update charts/website

Run the application with:

helm install charts/website

Feel free to check the status of the deployment with

kubectl get pods -w

Once all the pods are in a ready state, use the application by visiting the domain you used in the ingress.hosts value in your browser.

Running Tests

For the tests to work, you'll need a local installation of Postgres.

After installing Postgres, run the following.

createuser homestead --password secret --superuser
createdb website
createdb website_test

If you use different credentials, update the config/test-settings.yml file with whatever credentials you used.

Afterwards, you can run the tests simply by running

stack test
