 The Kerberos Agent is an isolated and scalable video (surveillance) management agent with a strong focus on user experience, scalability, resilience, extension and integration. Next to the Kerberos Agent, Kerberos.io provides many other tools such as [Kerberos Factory](https://github.com/kerberos-io/factory), [Kerberos Vault](https://github.com/kerberos-io/vault) and [Kerberos Hub](https://github.com/kerberos-io/hub) to provide additional capabilities: bring your own cloud, bring your own storage, central overview, live streaming, machine learning etc.

+Once installed you can find your Kerberos Agent configration at `/var/snap/kerberosio/common`. Run the Kerberos Agent as following.
+

+# Deployment with Terraform
+
+If you are using Terraform as part of your DevOps stack, you might utilise it to deploy your Kerberos Agents. Within this deployment folder we have added an example Terraform file `docker.tf`, which installs the Kerberos Agent `docker` container on a remote system over `SSH`. We might create our own provider in the future, or add additional examples for example `snap`, `kubernetes`, etc.
+
+For this example we will install Kerberos Agent using `docker` on a remote `linux` machine. Therefore we'll make sure we have the `TelkomIndonesia/linux` provider initialised.
+
+     terraform init
+
+Once initialised you should see similar output:
+
+    Initializing the backend...
+
+    Initializing provider plugins...
+    - Reusing previous version of telkomindonesia/linux from the dependency lock file
+    - Using previously-installed telkomindonesia/linux v0.7.0
+
+Go and open the `docker.tf` file and locate the `linux` provider, modify following credentials accordingly. Make sure they match for creating an `SSH` connection.
+
+    provider "linux" {
+        host     = "x.y.z.u"
+        port     = 22
+        user     = "root"
+        password = "password"
+    }
+
+Apply the `docker.tf` file, to install `docker` and the `kerberos/agent` docker container.
+
+    terraform apply
+
+Once done you should see following output, and you should be able to reach the remote machine on port `80` or if configured differently the specified port you've defined.
+
+    Do you want to perform these actions?
+    Terraform will perform the actions described above.
