Quickstart

In this quickstart we'll set up Infra to manage single sign-on to Kubernetes:

  • Install Infra CLI
  • Deploy Infra
  • Connect a Kubernetes cluster
  • Create a user and grant them view (read-only) access to the cluster

Prerequisites

1. Install Infra CLI

macOS
brew install infrahq/tap/infra

You may need to perform brew link if your symlinks are not working.

brew link infrahq/tap/infra
Windows
scoop bucket add infrahq https://github.com/infrahq/scoop.git
scoop install infra
Linux
# Ubuntu & Debian
echo 'deb [trusted=yes] https://apt.fury.io/infrahq/ /' | sudo tee /etc/apt/sources.list.d/infrahq.list
sudo apt update
sudo apt install infra
# Fedora & Red Hat Enterprise Linux
sudo dnf config-manager --add-repo https://yum.fury.io/infrahq/
sudo dnf install infra

2. Deploy Infra

Deploy an Infra to your Kubernetes cluster via helm:

helm repo add infrahq https://helm.infrahq.com/
helm repo update
helm install infra infrahq/infra

Next, find the hostname for Infra server you just deployed:

kubectl get service infra-server -o jsonpath="{.status.loadBalancer.ingress[*]['ip', 'hostname']}" -w

Note: It may take a few minutes for the LoadBalancer to be provisioned for the Infra server

Login to the Infra server using the hostname above and follow the prompt to create your admin account:

infra login <INFRA_SERVER_HOSTNAME> --skip-tls-verify

3. Connect your first Kubernetes cluster

Generate an access key:

infra keys add connector

Next, use this access key to connect your first cluster via helm. Note: this can be the same cluster used to install Infra in step 2.

Prepare your values:

  • connector.config.name: choose a name for this cluster
  • connector.config.server: the same hostname used for infra login
  • connector.config.accessKey: the key created above via infra keys add

Install the Infra connector via helm:

helm upgrade --install infra-connector infrahq/infra \
  --set connector.config.name=example-cluster \
  --set connector.config.server=<INFRA_SERVER_HOSTNAME> \
  --set connector.config.accessKey=<ACCESS_KEY> \
  --set connector.config.skipTLSVerify=true

| Note: it may take a few minutes for the cluster to connect. You can verify the connection by running infra destinations list

4. Add a user and grant access to the cluster

Next, add a user:

infra users add [email protected]

| Note: Infra will provide you a one-time password. Please note this password for step 5.

Grant this user read-only access to the Kubernetes cluster you just connected to Infra:

infra grants add [email protected] example-cluster --role view

5. Login as the example user and access the cluster:

Use the one-time password in the previous step to log in as the user. You'll be prompted to change the user's password since it's this new user's first time logging in.

infra login <INFRA_SERVER_HOSTNAME> --skip-tls-verify

Next, view this user's cluster access. You should see the user has view access to the example-cluster cluster connected above:

infra list

Lastly, switch to this Kubernetes cluster and verify the user's access:

infra use example-cluster

# Works since the user has view access
kubectl get pods -A

# Does not work
kubectl create namespace test-namespace

Congratulations, you've:

  • Installed Infra
  • Connected your first cluster
  • Created a user and granted them view access to the cluster
