Scheduler pods are in CrashLoopBackOff or Error state. This is because the setup is not complete.

5) Initialize the Configuration

First, download the initializer.yaml file.

wget https://raw.githubusercontent.com/cloudforet-io/charts/master/examples/initializer.yaml -O initializer.yaml

And execute the following command.

helm install cloudforet-initializer cloudforet/spaceone-initializer -n spaceone -f initializer.yaml

or

helm install cloudforet-initializer cloudforet/spaceone-initializer -n spaceone -f https://raw.githubusercontent.com/cloudforet-io/charts/master/examples/initializer.yaml

For more information about the initializer, please refer the spaceone-initializer.

6) Set the Helm Values and Upgrade the Chart

Complete the initialization, you can get the system token from the initializer pod logs.

# check pod name
kubectl logs initialize-spaceone-xxxx-xxxxx -n spaceone

...
TASK [Print Admin API Key] *********************************************************************************************
"{TOKEN}"

FINISHED [ ok=23, skipped=0 ] ******************************************************************************************

FINISH SPACEONE INITIALIZE

First, copy this TOKEN, then Create the values.yaml file and paste it to the TOKEN.

console:
  production_json:
    # If you don't have a service domain, you refer to the following 'No Domain & IP Access' example.
    CONSOLE_API:
      ENDPOINT: https://console.api.example.com       # Change the endpoint
    CONSOLE_API_V2:
      ENDPOINT: https://console-v2.api.example.com    # Change the endpoint

global:
  shared_conf:
    TOKEN: '{TOKEN}'                                    # Change the system token

For more advanced configuration, please refer the following the links.

After editing the values.yaml file, upgrade the helm chart.

helm upgrade cloudforet cloudforet/spaceone -n spaceone -f values.yaml
kubectl delete po -n spaceone -l app.kubernetes.io/instance=cloudforet

7) Check the status of the pods

kubectl get pod -n spaceone

If all pods are in Running state, the setup is complete.

8) Ingress and AWS Load Balancer

In Kubernetes, Ingress is an API object that provides a load-balanced external IP address to access Services in your cluster. It acts as a layer 7 (HTTP/HTTPS) reverse proxy and can route traffic to other services based on the requested host and URL path.

For more information, see What is an Application Load Balancer? on AWS and ingress in the Kubernetes documentation.

Prerequisite

Install AWS Load Balancer Controller
AWS Load Balancer Controller is a controller that helps manage ELB (Elastic Load Balancers) in a Kubernetes Cluster. Ingress resources are provisioned with Application Load Balancer, and service resources are provisioned with Network Load Balancer.
Installation methods may vary depending on the environment, so please refer to the official guide document below.

How to set up Cloudforet ingress

1) Ingress Type
Cloudforet provisions a total of 3 ingresses through 2 files.

  • Console : Ingress to access the domain
  • REST API : Ingress for API service
    • console-api
    • console-api-v2

2) Console ingress
Setting the ingress to accerss the console is as follows.

cat <<EOF> spaceone-console-ingress.yaml
---
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: console-ingress
  namespace: spaceone
  annotations:
    alb.ingress.kubernetes.io/listen-ports: '[{"HTTP": 80}]'
    alb.ingress.kubernetes.io/scheme: internet-facing
    alb.ingress.kubernetes.io/target-type: ip
    alb.ingress.kubernetes.io/load-balancer-attributes: idle_timeout.timeout_seconds=600
    alb.ingress.kubernetes.io/healthcheck-protocol: HTTP
    alb.ingress.kubernetes.io/success-codes: 200-399
    alb.ingress.kubernetes.io/load-balancer-name: spaceone-console-ingress # Caution!! Must be fewer than 32 characters.
spec:
  ingressClassName: alb
  defaultBackend:
    service:
      name: console
      port:
        number: 80
EOF

# Apply ingress
kubectl apply -f spaceone-console-ingress.yaml

If you apply the ingress, it will be provisioned to AWS Load Balancer with the name spaceone-console-ingress. You can connect through the provisioned DNS name using HTTP (80 Port).

3) REST API ingress
Setting the REST API ingress for the API service is as follows.

cat <<EOF> spaceone-rest-ingress.yaml
---
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: console-api-ingress
  namespace: spaceone
  annotations:
    alb.ingress.kubernetes.io/listen-ports: '[{"HTTP": 80}]'
    alb.ingress.kubernetes.io/scheme: internet-facing
    alb.ingress.kubernetes.io/target-type: ip
    alb.ingress.kubernetes.io/load-balancer-attributes: idle_timeout.timeout_seconds=600
    alb.ingress.kubernetes.io/healthcheck-protocol: HTTP
    alb.ingress.kubernetes.io/success-codes: 200-399
    alb.ingress.kubernetes.io/load-balancer-name: spaceone-console-api-ingress # Caution!! Must be fewer than 32 characters.
spec:
  ingressClassName: alb
  defaultBackend:
    service:
      name: console-api
      port:
        number: 80
---
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: console-api-v2-ingress
  namespace: spaceone
  annotations:
    alb.ingress.kubernetes.io/listen-ports: '[{"HTTP": 80}]'
    alb.ingress.kubernetes.io/scheme: internet-facing
    alb.ingress.kubernetes.io/target-type: ip
    alb.ingress.kubernetes.io/load-balancer-attributes: idle_timeout.timeout_seconds=600
    alb.ingress.kubernetes.io/healthcheck-protocol: HTTP
    alb.ingress.kubernetes.io/success-codes: 200-399
    alb.ingress.kubernetes.io/load-balancer-name: spaceone-console-api-v2-ingress
spec:
  ingressClassName: alb
  defaultBackend:
    service:
      name: console-api-v2-rest
      port:
        number: 80
EOF

# Apply ingress
kubectl apply -f spaceone-rest-ingress.yaml

REST API ingress provisions two ALBs. The DNS Name of the REST API must be saved as console.CONSOLE_API.ENDPOINT and console.CONSOLE_API_V2.ENDPOINT in the values.yaml file.

4) Check DNS Name
The DNS name will be generated as http://{ingress-name}-{random}.{region-code}.elb.amazoneaws.com. You can check this through the kubectl get ingress -n spaceone command in Kubernetes.

kubectl get ingress -n spaceone

NAME                     CLASS   HOSTS   ADDRESS                                                                      PORTS   AGE
console-api-ingress      alb     *       spaceone-console-api-ingress-xxxxxxxxxx.{region-code}.elb.amazonaws.com      80      15h
console-api-v2-ingress   alb     *       spaceone-console-api-v2-ingress-xxxxxxxxxx.{region-code}.elb.amazonaws.com   80      15h
console-ingress          alb     *       spaceone-console-ingress-xxxxxxxxxx.{region-code}.elb.amazonaws.com          80      15h

Or, you can check it in AWS Console. You can check it in EC2 > Load balancer as shown in the image below.

spaceone-console-ingress-alb

5) Connect with DNS Name
When all ingress is ready, edit the values.yaml file, restart pods, and access the console.

console:
  production_json:
    # If you don't have a service domain, you refer to the following 'No Domain & IP Access' example.
    CONSOLE_API:
      ENDPOINT: http://spaceone-console-api-ingress-xxxxxxxxxx.{region-code}.elb.amazonaws.com
    CONSOLE_API_V2:
      ENDPOINT: http://spaceone-console-api-v2-ingress-xxxxxxxxxx.{region-code}.elb.amazonaws.com

After applying the prepared values.yaml file, restart the pods.

helm upgrade cloudforet cloudforet/spaceone -n spaceone -f values.yaml
kubectl delete po -n spaceone -l app.kubernetes.io/instance=cloudforet

Now you can connect to Cloudforet with the DNS Name of spaceone-console-ingress.

  • http://spaceone-console-ingress-xxxxxxxxxx.{region-code}.elb.amazonaws.com

Advanced ingress settings

How to register an SSL certificate
We will guide you through how to register a certificate in ingress for SSL communication.
There are two methods for registering a certificate. One is when using ACM(AWS Certificate Manager), and the other is how to register an external certificate.

How to register an ACM certificate with ingress
If the certificate was issued through ACM, you can register the SSL certificate by simply registering acm arn in ingress.

First of all, please refer to the AWS official guide document on how to issue a certificate.

How to register the issued certificate is as follows. Please check the options added or changed for SSL communication in existing ingress.

Check out the changes in ingress.
Various settings for SSL are added and changed. Check the contents of metadata.annotations.
Also, check the added contents such as ssl-redirect and spec.rules.host in spec.rules.

How to register an SSL/TLS certificate
Certificate registration is possible even if you have an external certificate that was previously issued. You can register by adding a Kubernetes secret using the issued certificate and declaring the added secret name in ingress.

Create SSL/TLS certificates as Kubernetes secrets. There are two ways:

1. Using yaml file
You can add a secret to a yaml file using the command below.

kubectl apply -f <<EOF> tls-secret.yaml
apiVersion: v1
data:
  tls.crt: {your crt}   # crt
  tls.key: {your key}   # key
kind: Secret
metadata:
  name: tls-secret
  namespace: spaceone
type: kubernetes.io/tls

2. How to use the command if a file exists
If you have a crt and key file, you can create a secret using the following command.

kubectl create secret tls tlssecret --key tls.key --cert tls.crt

Add tls secret to Ingress
Modify ingress using registered secret information.

ingress-nginx settings
Using secret and tls may require setup methods using ingress-nginx. For more information, please refer to the following links:
