# Installation and setup
Constellation runs entirely in your cloud environment and can be controlled via a dedicated [command-line interface (CLI)](../reference/cli.md) or a [Terraform provider](../workflows/terraform-provider.md).
## Prerequisites
Make sure the following requirements are met:
* Your machine is running Linux, macOS, or Windows
* You have admin rights on your machine
* [kubectl](https://kubernetes.io/docs/tasks/tools/) is installed
* Your CSP is Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform (GCP), or STACKIT
## Install the Constellation CLI
:::tip
If you prefer to use Terraform, you can alternatively use the [Terraform provider](../workflows/terraform-provider.md) to manage the cluster's lifecycle.
:::

## Set up cloud credentials
Constellation makes authenticated calls to the CSP API. Therefore, you need to set up Constellation with the credentials for your CSP.
:::tip
If you don't have a cloud subscription, you can also set up a [local Constellation cluster using virtualization](../getting-started/first-steps-local.md) for testing.
:::
### Required permissions
<Tabs groupId="csp">
<TabItem value="aws" label="AWS">
To set up a Constellation cluster, you need to perform two tasks that require permissions: create the infrastructure and create roles for cluster nodes. Both of these actions can be performed by different users, e.g., an administrator to create roles and a DevOps engineer to create the infrastructure.
To [create the IAM configuration](../workflows/config.md#creating-an-iam-configuration) for Constellation, you need the following permissions:
```json
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": [
"ec2:DescribeAccountAttributes",
"iam:AddRoleToInstanceProfile",
"iam:AttachRolePolicy",
"iam:CreateInstanceProfile",
"iam:CreatePolicy",
"iam:CreateRole",
"iam:DeleteInstanceProfile",
"iam:DeletePolicy",
"iam:DeletePolicyVersion",
"iam:DeleteRole",
"iam:DetachRolePolicy",
"iam:GetInstanceProfile",
"iam:GetPolicy",
"iam:GetPolicyVersion",
"iam:GetRole",
"iam:ListAttachedRolePolicies",
"iam:ListInstanceProfilesForRole",
"iam:ListPolicyVersions",
"iam:ListRolePolicies",
"iam:PassRole",
"iam:RemoveRoleFromInstanceProfile",
"sts:GetCallerIdentity"
],
"Resource": "*"
}
]
}
```
The built-in `AdministratorAccess` policy is a superset of these permissions.
To [create a Constellation cluster](../workflows/create.md), see the permissions of [main.tf](https://github.com/edgelesssys/constellation/blob/main/terraform/infrastructure/iam/aws/main.tf).
The built-in `PowerUserAccess` policy is a superset of these permissions.
Follow Amazon's guide on [understanding](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies.html) and [managing policies](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies_managed-vs-inline.html).
</TabItem>
<TabItem value="azure" label="Azure">
The following [resource providers need to be registered](https://learn.microsoft.com/en-us/azure/azure-resource-manager/management/resource-providers-and-types#register-resource-provider) in your subscription:
* `Microsoft.Attestation`
* `Microsoft.Compute`
* `Microsoft.Insights`
* `Microsoft.ManagedIdentity`
* `Microsoft.Network`
By default, Constellation tries to register these automatically if they haven't been registered before.
To [create the IAM configuration](../workflows/config.md#creating-an-iam-configuration) for Constellation, you need the following permissions:
* `*/register/action` \[1]
* `Microsoft.Authorization/roleAssignments/*`
* `Microsoft.Authorization/roleDefinitions/*`
* `Microsoft.ManagedIdentity/userAssignedIdentities/*`
* `Microsoft.Resources/subscriptions/resourcegroups/*`
The built-in `Owner` role is a superset of these permissions.
To [create a Constellation cluster](../workflows/create.md), you need the following permissions:
* `Microsoft.Attestation/attestationProviders/*`
* `Microsoft.Compute/virtualMachineScaleSets/*`
* `Microsoft.Insights/components/*`
* `Microsoft.ManagedIdentity/userAssignedIdentities/*`
* `Microsoft.Network/loadBalancers/*`
* `Microsoft.Network/loadBalancers/backendAddressPools/*`
* `Microsoft.Network/networkSecurityGroups/*`
* `Microsoft.Network/publicIPAddresses/*`
* `Microsoft.Network/virtualNetworks/*`
* `Microsoft.Network/virtualNetworks/subnets/*`
* `Microsoft.Network/natGateways/*`
The built-in `Contributor` role is a superset of these permissions.
Follow Microsoft's guide on [understanding](https://learn.microsoft.com/en-us/azure/role-based-access-control/role-definitions) and [assigning roles](https://learn.microsoft.com/en-us/azure/role-based-access-control/role-assignments).
1: You can omit `*/register/Action` if the resource providers mentioned above are already registered and the `ARM_SKIP_PROVIDER_REGISTRATION` environment variable is set to `true` when creating the IAM configuration.

<TabItem value="stackit" label="STACKIT">
Constellation on STACKIT requires a User Access Token (UAT) for the OpenStack API and a STACKIT service account.
The UAT already has all required permissions by default.
The STACKIT service account needs the `editor` role to create STACKIT LoadBalancers.
Look at the [STACKIT documentation](https://docs.stackit.cloud/stackit/en/getting-started-in-service-accounts-134415831.html) on how to create the service account and assign the role.

### Authentication
You need to authenticate with your CSP. The following lists the required steps for *testing* and *production* environments.
:::note
The steps for a *testing* environment are simpler. However, they may expose secrets to the CSP. If in doubt, follow the *production* steps.
:::
<Tabs groupId="csp">
<TabItem value="aws" label="AWS">
**Testing**
You can use the [AWS CloudShell](https://console.aws.amazon.com/cloudshell/home). Make sure you are [authorized to use it](https://docs.aws.amazon.com/cloudshell/latest/userguide/sec-auth-with-identities.html).
**Production**
Use the latest version of the [AWS CLI](https://aws.amazon.com/cli/) on a trusted machine:
```bash
aws configure
```
Options and first steps are described in the [AWS CLI documentation](https://docs.aws.amazon.com/cli/index.html).
</TabItem>
<TabItem value="azure" label="Azure">
**Testing**
Simply open the [Azure Cloud Shell](https://docs.microsoft.com/en-us/azure/cloud-shell/overview).
**Production**
Use the latest version of the [Azure CLI](https://docs.microsoft.com/en-us/cli/azure/) on a trusted machine:
```bash
az login
```
Other options are described in Azure's [authentication guide](https://docs.microsoft.com/en-us/cli/azure/authenticate-azure-cli).
</TabItem>
<TabItem value="gcp" label="GCP">
**Testing**
You can use the [Google Cloud Shell](https://cloud.google.com/shell). Make sure your [session is authorized](https://cloud.google.com/shell/docs/auth). For example, execute `gsutil` and accept the authorization prompt.
**Production**
Use one of the following options on a trusted machine:
* Use the [`gcloud` CLI](https://cloud.google.com/sdk/gcloud)
```bash
gcloud auth application-default login
```
This will ask you to log-in to your Google account and create your credentials.
The Constellation CLI will automatically load these credentials when needed.
* Set up a service account and pass the credentials manually
Follow [Google's guide](https://cloud.google.com/docs/authentication/production#manually) for setting up your credentials.
</TabItem>
<TabItem value="stackit" label="STACKIT">
You need to authenticate with the infrastructure API (OpenStack) and create a service account (STACKIT API).
1. [Follow the STACKIT documentation](https://docs.stackit.cloud/stackit/en/step-1-generating-of-user-access-token-11763726.html) for obtaining a User Access Token (UAT) to use the infrastructure API
2. Create a configuration file under `~/.config/openstack/clouds.yaml` (`%AppData%\openstack\clouds.yaml` on Windows) with the credentials from the User Access Token
```yaml
clouds:
stackit:
auth:
auth_url: https://keystone.api.iaas.eu01.stackit.cloud/v3
username: REPLACE_WITH_UAT_USERNAME
password: REPLACE_WITH_UAT_PASSWORD
project_id: REPLACE_WITH_STACKIT_PROJECT_ID
project_name: REPLACE_WITH_STACKIT_PROJECT_NAME
user_domain_name: portal_mvp
project_domain_name: portal_mvp
region_name: RegionOne
identity_api_version: 3
```
3. [Follow the STACKIT documentation](https://docs.stackit.cloud/stackit/en/getting-started-in-service-accounts-134415831.html) for creating a service account and an access token
4. Assign the `editor` role to the service account by [following the documentation](https://docs.stackit.cloud/stackit/en/getting-started-in-service-accounts-134415831.html)
5. Create a configuration file under `~/.stackit/credentials.json` (`%USERPROFILE%\.stackit\credentials.json` on Windows)
```json
{"STACKIT_SERVICE_ACCOUNT_TOKEN":"REPLACE_WITH_TOKEN"}
```
