## Prerequisites:
|
|
|
|
In order to run the Postgres operator locally in minikube you need to install the following tools:
|
|
|
|
* [minikube](https://github.com/kubernetes/minikube/releases)
|
|
* [kubectl](https://kubernetes.io/docs/tasks/tools/install-kubectl/#install-kubectl-binary-via-curl)
|
|
|
|
Note that you can also use built-in Kubernetes support in the Docker Desktop
|
|
for Mac to follow the steps of this tutorial. You would have to replace
|
|
`minikube start` and `minikube delete` with your launch actionsfor the Docker
|
|
built-in Kubernetes support.
|
|
|
|
## Local execution
|
|
|
|
```bash
|
|
git clone https://github.com/zalando-incubator/postgres-operator.git
|
|
cd postgres-operator
|
|
|
|
minikube start
|
|
|
|
# start the operator; may take a few seconds
|
|
kubectl create -f manifests/configmap.yaml # configuration
|
|
kubectl create -f manifests/operator-service-account-rbac.yaml # identity and permissions
|
|
kubectl create -f manifests/postgres-operator.yaml # deployment
|
|
|
|
# create a Postgres cluster
|
|
kubectl create -f manifests/minimal-postgres-manifest.yaml
|
|
|
|
# connect to the Postgres master via psql
|
|
# operator creates the relevant k8s secret
|
|
export HOST_PORT=$(minikube service acid-minimal-cluster --url | sed 's,.*/,,')
|
|
export PGHOST=$(echo $HOST_PORT | cut -d: -f 1)
|
|
export PGPORT=$(echo $HOST_PORT | cut -d: -f 2)
|
|
export PGPASSWORD=$(kubectl get secret postgres.acid-minimal-cluster.credentials -o 'jsonpath={.data.password}' | base64 -d)
|
|
psql -U postgres
|
|
|
|
# tear down cleanly
|
|
minikube delete
|
|
```
|
|
|
|
We have automated starting the operator and submitting the `acid-minimal-cluster` for you:
|
|
```bash
|
|
cd postgres-operator
|
|
./run_operator_locally.sh
|
|
```
|
|
|
|
## Running and testing the operator
|
|
|
|
The best way to test the operator is to run it in [minikube](https://kubernetes.io/docs/getting-started-guides/minikube/).
|
|
Minikube is a tool to run Kubernetes cluster locally.
|
|
|
|
### Configuration Options
|
|
|
|
The operator can be configured with the provided ConfigMap (`manifests/configmap.yaml`).
