<h1>Postgres Operator UI</h1>
|
|
|
|
The Postgres Operator UI provides a graphical interface for a convenient
|
|
database-as-a-service user experience. Once the operator is set up by database
|
|
and/or Kubernetes (K8s) admins it's very easy for other teams to create, clone,
|
|
watch, edit and delete their own Postgres clusters. Information on the setup
|
|
and technical details can be found in the [admin docs](administrator.md#setting-up-the-postgres-operator-ui).
|
|
|
|
## Create a new cluster
|
|
|
|
In the top menu select the "New cluster" option and adjust the values in the
|
|
text fields. The cluster name is composed of the team plus given name. Among the
|
|
available options are [enabling load balancers](administrator.md#load-balancers-and-allowed-ip-ranges),
|
|
[volume size](user.md#increase-volume-size),
|
|
[users and databases](user.md#manifest-roles) and
|
|
[pod resources](cluster-manifest.md#postgres-container-resources).
|
|
|
|
|
|
|
|
On the left side you will see a preview of the Postgres cluster manifest which
|
|
is applied when clicking on the green "Create cluster" button.
|
|
|
|
## Cluster starting up
|
|
|
|
After the manifest is applied to K8s the Postgres Operator will create all
|
|
necessary resources. The progress of this process can nicely be followed in UI
|
|
status page.
|
|
|
|
|
|
|
|
|
|
|
|
Usually, the startup should only take up to 1 minute. If you feel the process
|
|
got stuck click on the "Logs" button to inspect the operator logs. If the logs
|
|
look fine, but the UI seems to got stuck, check if you are have configured the
|
|
same [cluster name label](https://github.com/zalando/postgres-operator/blob/master/ui/manifests/deployment.yaml#L45) like for the
|
|
[operator](https://github.com/zalando/postgres-operator/blob/master/manifests/configmap.yaml#L13).
|
|
|
|
From the "Status" field in the top menu you can also retrieve the logs and queue
|
|
of each worker the operator is using. The number of concurrent workers can be
|
|
[configured](reference/operator_parameters.md#general).
|
|
|
|
|
|
|
|
Once the startup has finished you will see the cluster address path. When load
|
|
balancers are enabled the listed path can be used as the host name when
|
|
connecting to PostgreSQL. But, make sure your IP is within the specified
|
|
`allowedSourceRanges`.
|
|
|
|
|
|
|
|
## Update and delete clusters
|
|
|
|
Created clusters are listed under the menu "PostgreSQL clusters". You can get
|
|
back to cluster's status page via the "Status" button. From both menus you can
|
|
choose to edit the manifest, [clone](user.md#how-to-clone-an-existing-postgresql-cluster)
|
|
or delete a cluster.
|
|
|
|
|
|
|
|
Note, that not all [manifest options](reference/cluster_manifest.md) are yet
|
|
supported in the UI. If you try to add them in the editor view it won't have an
|
|
effect. Use `kubectl` commands instead. The displayed manifest on the left side
|
|
will also show parameters patched that way.
|
|
|
|
When deleting a cluster you are asked to type in its namespace and name to
|
|
confirm the action.
