How to install Dockup

Follow these steps, and you should be all good with a dockup installation where you can deploy serveral staging sites loadbalanced by traefik. You need a working google kubernetes cluster. Ensure that you are able to connect to it using kubectl

Step 1: Get helm working

> helm init
> kubectl create serviceaccount --namespace kube-system tiller
> kubectl create clusterrolebinding tiller-cluster-rule --clusterrole=cluster-admin \
    --serviceaccount=kube-system:tiller
> kubectl patch deploy --namespace kube-system tiller-deploy \
    -p '{"spec":{"template":{"spec":{"serviceAccount":"tiller"}}}}'

This helm + tiller installation is to get you started asap. If you need more control over security, please open a github issue with your requirements, we would be more than happy to help out.

Step 2: Elevate your credentials for assigning roles

> kubectl create clusterrolebinding yuva-cluster-admin-binding \
    --clusterrole=cluster-admin --user=<your-email-used-for-gke>

Step 3: Add these helm charts as repository

Now add codemancers chart repository to your helm config

helm repo add dockup https://helm-charts.getdockup.com

Time to time, its advised to update helm repository caches

helm repo update

Installing dockup

After adding a new helm repository, install dockup as helm package

> helm install --name=dockup dockup/dockup

The above commands installs postgresql required by dockup

You need to have traefik or nginx ingress in order to expose dockup to external world. Also, its recommended to set custom values in yaml file, say dockup.yaml and then install dockup.

> helm install -f dockup.yaml --name=dockup dockup/dockup

Installing db-pool

Db-pool is used to create a farm of pre-poulated databases which can be connected to dockup deployments. This saves time when it comes to spinning up new testing sites.

> helm install --name=db-pool dockup/db-pool

The above commands installs postgresql required by db-pool, and mysql. Currently db-pool only supports managing of mysql databases.

Its recommended to set all these values in yaml file, say db-pool.yaml and then install it

> helm install -f db-pool.yaml --name=db-pool dockup/db-pool

Installing dockup agent

After adding a new helm repository, install dockup as helm package

> helm install --name=dockup-agent dockup/agent

The above commands installs postgresql required by dockup

You need to have traefik or nginx ingress in order to expose dockup to external world. Also, its recommended to set custom values in yaml file, say agent.yaml and then install dockup.

> helm install -f agent.yaml --name=dockup-agent dockup/agent

GKE pull secrets

In order to pull images from private GCP registry, you need to download API credentials for service account, and encode them, and provide it to the agent chart. GCP credentials consist of project_id, private_key_id, private_key etc. Download that file, and base64 encode that file. Once encoded, create docker auth.

export json_key=$(echo _json_key:$(cat path-to-api-json) | base64)
printf '{"auths": {"gcr.io":{"auth":"%s"}}}' $json_key | base64

Take the output of second line and feed it to this helm chart as pullSecretBase64. Now agent should be able to pull images from your private repository.
