= Installing Strimzi

Using the xref:proc-product-downloads-{context}[download files], install Strimzi with the Custom Resource Definitions (CRDs) and RBAC configuration required for deployment.

In this task you create namespaces in the cluster for your deployment.
Use namespaces to separate functions.

.Prerequisites

* Installation requires a Kubernetes account with cluster admin credentials.

.Procedure

. Log in to the Kubernetes cluster using an account that has cluster admin privileges.

. Create a new `kafka` namespace for the Strimzi Kafka Cluster Operator.
+
[source, shell, subs=+quotes ]
----
kubectl create ns kafka
----

. Modify the installation files to reference the `kafka` namespace where you will install the Strimzi Kafka Cluster Operator.
+
NOTE: By default, the files work in the `myproject` namespace.
+
* On Linux, use:
+

[source, shell, subs=+quotes]
----
sed -i 's/namespace: .\*/namespace: kafka/' install/cluster-operator/*RoleBinding*.yaml
----
+
* On Mac, use:
+
[source, shell, subs=+quotes]
----
sed -i '' 's/namespace: .\*/namespace: kafka/' install/cluster-operator/*RoleBinding*.yaml
----

. Create a new `my-kafka-project` namespace where you will deploy your Kafka cluster.
+
[source, shell, subs=+quotes ]
----
kubectl create ns my-kafka-project
----

. Edit the `install/cluster-operator/060-Deployment-strimzi-cluster-operator.yaml` file and set the `STRIMZI_NAMESPACE` environment variable to the namespace `my-kafka-project`.
+
[source, yaml, subs=+quotes ]
----
# ...
env:
- name: STRIMZI_NAMESPACE
  value: my-kafka-project
# ...
----

. Deploy the CRDs and role-based access control (RBAC) resources to manage the CRDs.
+
[source, shell, subs=+quotes ]
----
kubectl create -f install/cluster-operator/ -n kafka
----

. Give permission to the Cluster Operator to watch the `my-kafka-project` namespace.
+
--
[source, shell, subs=+quotes]
----
kubectl create -f install/cluster-operator/020-RoleBinding-strimzi-cluster-operator.yaml -n my-kafka-project
----
[source, shell, subs=+quotes]
----
kubectl create -f install/cluster-operator/031-RoleBinding-strimzi-cluster-operator-entity-operator-delegation.yaml -n my-kafka-project
----

+
The commands create role bindings that grant permission for the Cluster Operator to access the Kafka cluster.
