Phabricator

Phabricator is a collection of open source web applications that help software companies build better software. Phabricator is built by developers for developers. Every feature is optimized around developer efficiency for however you like to work. Code Quality starts with an effective collaboration between team members.

TL;DR;

$ helm install stable/phabricator

Introduction

This chart bootstraps a Phabricator deployment on a Kubernetes cluster using the Helm package manager.

It also packages the Bitnami MariaDB chart which is required for bootstrapping a MariaDB deployment for the database requirements of the Phabricator application.

Bitnami charts can be used with Kubeapps for deployment and management of Helm Charts in clusters. This chart has been tested to work with NGINX Ingress, cert-manager, fluentd and Prometheus on top of the BKPR.

Prerequisites

• Kubernetes 1.4+ with Beta APIs enabled
• PV provisioner support in the underlying infrastructure

Installing the Chart

To install the chart with the release name my-release:

$ helm install --name my-release stable/phabricator

The command deploys Phabricator on the Kubernetes cluster in the default configuration. The configuration section lists the parameters that can be configured during installation.

Tip

: List all releases using helm list

Uninstalling the Chart

To uninstall/delete the my-release deployment:

$ helm delete my-release

The command removes all the Kubernetes components associated with the chart and deletes the release.

Note

:

For Phabricator to function correctly, you should specify the phabricatorHost parameter to specify the FQDN (recommended) or the public IP address of the Phabricator service.

Optionally, you can specify the phabricatorLoadBalancerIP parameter to assign a reserved IP address to the Phabricator service of the chart. However please note that this feature is only available on a few cloud providers (f.e. GKE).

To reserve a public IP address on GKE:

$ gcloud compute addresses create phabricator-public-ip

The reserved IP address can be associated to the Phabricator service by specifying it as the value of the phabricatorLoadBalancerIP parameter while installing the chart.

Specify each parameter using the --set key=value[,key=value] argument to helm install. For example,

$ helm install stable/phabricator --name my-release \
  --set phabricatorUsername=admin,phabricatorPassword=password,mariadb.mariadbRootPassword=secretpassword \

The above command sets the Phabricator administrator account username and password to admin and password respectively. Additionally, it sets the MariaDB root user password to secretpassword.

Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart. For example,

$ helm install --name my-release -f values.yaml stable/phabricator

Tip

: You can use the default values.yaml

Rolling VS Immutable tags

It is strongly recommended to use immutable tags in a production environment. This ensures your deployment does not change automatically if the same tag is updated with a different image.

Bitnami will release a new chart updating its containers if a new version of the main container, significant changes, or critical vulnerabilities exist.

Persistence

The Bitnami Phabricator image stores the Phabricator data and configurations at the /bitnami/phabricator path of the container.

Persistent Volume Claims are used to keep the data across deployments. There is a known issue in Kubernetes Clusters with EBS in different availability zones. Ensure your cluster is configured properly to create Volumes in the same availability zone where the nodes are running. Kuberentes 1.12 solved this issue with the Volume Binding Mode.

See the Configuration section to configure the PVC or to disable persistence.

Ingress with Reverse Proxy and cert-manager

You can define a custom ingress rule for Phabricator with TLS certificates auto-generated by cert-manager as follows:

$ helm install stable/phabricator --name my-release \
  --set ingress.enabled=true \
  --set ingress.certManager=true \
  --set ingress.hosts[0].name=phabricator.example.com \
  --set ingress.tls[0].hosts[0]=phabricator.example.com \
  --set phabricatorHost=example.com

Everything looks great but requests over https will cause asset requests to fail. Assuming you want to use HTTPS/TLS you will need to set the base-uri to an https schema.

$ export POD_NAME=$(kubectl get pods -l "app.kubernetes.io/name=phabricator,app.kubernetes.io/instance=my-release" -o jsonpath="{.items[0].metadata.name}")
$ kubectl exec $POD_NAME /opt/bitnami/phabricator/bin/config set phabricator.base-uri https://phabricator.example.com

Upgrading

To 7.0.0

Backwards compatibility is not guaranteed. The following notables changes were included:

• Labels are adapted to follow the Helm charts best practices.
• The parameters persistence.phabricator.storageClass, persistence.phabricator.accessMode, and persistence.phabricator.size switch to persistence.storageClass, persistence.accessMode, and persistence.size.
• The way of setting the ingress rules has changed. Instead of using ingress.paths and ingress.hosts as separate objects, you should now define the rules as objects inside the ingress.hosts value, for example:

ingress:
  hosts:
  - name: phabricator.local
    path: /

To 3.0.0

Backwards compatibility is not guaranteed unless you modify the labels used on the chart's deployments. Use the workaround below to upgrade from versions previous to 3.0.0. The following example assumes that the release name is opencart:

$ kubectl patch deployment opencart-opencart --type=json -p='[{"op": "remove", "path": "/spec/selector/matchLabels/app"}]'
$ kubectl delete statefulset opencart-mariadb --cascade=false
