eva server Installation guide

Why use Helm?

Helm can make deployments easier and repeatable because all resources for an application are deployed by running one command:

$ helm install <chart>

With Helm, configuration settings are kept separate from the manifest formats. You can edit the configuration values without changing the rest of the manifest.

Configuration settings are in a values.yaml file. You update the runtime parameters in that file to deploy each application instance differently.

You can use single commands for installing, upgrading, and deleting eva releases. More information about Helm at https://helm.sh/.

Description

This chapter describes the design and governance for the eva 4 helm charts.

These helm charts are designed to be a lightweight way to configure, package and deploy eva admin and eva instance resources onto Kubernetes clusters, both for a single installation and multicluster installation. These charts are currently tested against the following versions:

eva application: 4.1.0
Helm: 3.5.0
Kubernetes: 1.22
Istio: 1.11.7

The GitLab repository for these charts is eva4-helm-repository. Following is a description of repository each folder:

eva-admin-charts

- eva-admin-saas-resources: a chart to deploy the components for eva admin SaaS.
- eva-admin-rabbitmq: a chart to deploy the rabbitmq cluster operator and cert manager for rabbitmq.
- keycloak: contains the keycloak-values.yaml file to use with helm installation to deploy a keycloak.
- minio: contains the values.yaml file to use with helm installation to install Minio.
- eva-admin-rabbitmq-server: a chart to deploy the rabbitmq messaging topology operator and rabbitmq resources.

  - eva-core: a chart to deploy the core components for eva admin.
  - eva-envoy-config: a chart to deploy eva-decrypt-filter and eva-envoy-filter resources.
eva-configuration-charts:
- eva-organization: chart to launch a job to create a new organization for the instance.
- eva-instance-config-server-post: chart to run configurations jobs, where:
  - instance-default-config-job: apply the default configuration for an instance.
  - instance-honeypot-config-job: apply the honeypot configuration for an instance.
- eva-environment: chart to launch a job to create or update an environment for the instance.

Important eva 4 helm charts configuration

eva deployment with Helm requires very little configuration to get started, but there are several components which must be considered before the installation:

NodeSelector

If the application environment is based on multi-node pool architecture, uncomment the nodeSelector section with the specific label into chart Values.yaml files, and check if the label has been added on node pools.

If there is no node selection constraint, comment the nodeSelector section into values.yaml files.

PullSecret

If the application environment uses a private container registry with authentication, uncomment the imagePullSecret section with the specific name chart values.yaml files.

If login information is not requiring, comment the imagePullSecret section into values.yaml files.

Redis and MongoDB

If the application environment uses a mongodb or/and redis as a service in the cloud, it will be mandatory to provide the configuration data of these cloud services into redis and mongo section of eva-admin-base-resources, eva-admin-server, eva-instance-base-resources, eva-instance-server and eva-enviroment values.yaml files.

Remember include the redis cidr range into eva-admin-saas-resources and eva-instance-saas-resources values.yaml.

Single Installation

For a single server cluster, set true the single_installation option into enabled_components in eva-instance-base-resources, eva-instance-saas-resources and eva-instance-server values.yaml files.

Usernames, service name and passwords

The following charts are not meant to be executed as they are - They contain fields such as passwords, usernames and service names (Found as [YOUR-SERVICE], 'password-in-plain-text', etc). Please read carefully and make the proper substitutions for each of them.

Wait before executing the post config charts

During the admin cluster installation, keep in mind these tips:

Before executing eva-admin-rabbitmq-config chart, it must be validated that eva-rabbitmq-server pod has been successfully deployed.
Before executing eva-config-server-post chart, it must be validated that eva-config-server pod has been successfully deployed.
Before executing eva-admin-keycloak-realm-post chart, it must be validated that keycloak has been successfully installed.

Admin Charts

eva-admin-base-resources

eva-admin-base-resources allows you set base components for eva admin application. You can activate the section for pull secret if you need use authentication to container Registry. Also, it's possible to configure nodeSelector option for the deployment.

The following namespaces are deployed: eva-admin, minio and keycloak. Also, eva-gateway and eva-gateway-internal are installed.

The code below is the eva-admin-base-resources Values.yaml:

## @Section Admin Config Server Global info 
## Used to SPRING_CLOUD_CONFIG_LABEL
admin_instance_name: "admin-1"
 ## Used to SPRING_CLOUD_CONFIG_PROFILE
admin_config_server_profile: "default"

## @Section Admin Redis 
redis_host: "172.30.0.20"
## This password is not in base64 encoded
redis_pass: "password-in-clear-text"
redis_port: 6379
redis_ssl: false
redis_cachetype: "redis"
      
## @Section TLS: configures SSL certificates.
## These passwords are in base64 encoded
eva_tls:
  crt: ***
  key: ***
  
keycloak_tls:
  crt: ***
  key: ***
 
## @Section Pull Secrets
## If no value specified for section pull secret, neither the 
## secret nor the deployments will use authentication to Container Registry.
# imagePullSecrets: 
#   name: "containerregistrysecret"
#   configjson: "***"

eva-admin-saas-resources

Remember, eva-admin-saas-resources must only be used in eva-cloud installations, and this section should be ignored on eva-server installations.

It allows you set SaaS components for eva admin application, network policies, load balancer components and Istio Addons like, Prometheus, Grafana and Kiali. You can choose to deploy optional Istio tunning components. To do this, set true istio_tunning in the enabled_components section in values.yaml file. In addition, you can deploy Prometheus with a pvc, setting true prometheus_with_pvc in the enabled_components section as detailed below:

## @Section Optional Components
enabled_components:
  istio_tunning: "true"
  prometheus_with_pvc: "true"

This chart also allows to change the image tag version of each component, and container registry name. You can activate the section for pull secret if you need use authentication to container registry. Also, it's possible to configure nodeSelector option for the deployment. Do this with Values.yaml customization.

Remember: once installed this chart, the ingress spreading to GKE can be delayed for 5 to 10 minutes.

The code below is the eva-admin-saas-resources Values.yaml:

## Admin Name (without double quotes)
## admin_dns_output.value.public_dns_records.general.name - Use only the url prefix 
## For this chart is the base domain name for grafana, kiali, prometheus and tracing
admin_name: [YOUR-SERVICE]-env-admin

## @Section Optional Components
enabled_components:
  ## Set true to deploy extra config to Prometheus, Kiali and Tracing Istio 
  istio_tunning: "true"
  ## Set true to deploy Prometheus with persistence
  prometheus_with_pvc: "true"

Configuration Charts

Configuration charts consists of several charts to apply configuration changes to a set elements in both admin and instances cluster. Each chart has a purpose.

eva-instance-config-server-post

Remember: Before creating a new instance, eva-instance-config-server-post chart has been released into admin cluster to apply configuration changes for an instance.

This chart executes two jobs to apply configurations changes for an instance:

instance-default-config-job: apply the default configuration for an instance.
instance-honeypot-config-job: apply the honeypot configuration for an instance.

The code below is the eva-instance-config-server-post Values.yaml:

## Instance Name
## Used to label in *-config-data.json
instance_name: "[YOUR-SERVICE]-env-instance2"
## Used to profile in *-config-data.json

Instance Charts

eva-instance-base-resources

eva-instance-base-resources allows you set base components for eva instance application. You can activate the section for pull secret if you need use authentication to container Registry. Also, it's possible to configure nodeSelector option for the deployment.

Remember: for a single server installation, set true single_installation in enabled_components into optional section in eva-instance-base-resources Values.yaml file.

The namespace eva is created and eva-gateway id deployed only if not single installation. The code below is the eva-instance-base-resources Values.yaml:

eva-instance-saas-resources

Remember, eva-admin-saas-resources must only be used in eva-cloud installations, and this section should be ignored on eva-server installations.

It allows you set SaaS components for eva instance application, network policies, load balancer components and Istio Addons like, Prometheus, Grafana and Kiali. You can choose to deploy optional Istio tunning components. To do this, set true istio_tunning in the enabled_components section in values.yaml file. In addition, you can deploy Prometheus with a pvc, setting true prometheus_with_pvc in the enabled_components section as detailed below.

## @Section optional components
## Set true to deploy optional components.

Usage

Admin Cluster

Once you have installed or checked the dependencies needed onto system (review the section Supported Configurations for this), execute in order, the following commands to deploy ADMIN charts for the eva admin cluster:

Install eva-admin-base-resources chart.

helm upgrade --install eva-admin-base-resources .

Additionally, install the eva-admin-saas-resources chart if you're installing an eva-cloud solution. Once installed, the ingress spreading to GKE can be delayed for 5 to 10 minutes.

Remember, eva-admin-saas-resources must only be used in eva-cloud installations, and the following command should be ignored on eva-server installations.

helm upgrade --install eva-admin-saas-resources .

2. Install eva-admin-rabbitmq chart.

 helm upgrade --install eva-admin-rabbitmq .

3. In this step, execute the following commands to install the codecentric/keycloak chart archive. You can isntall min.io with PVC or Google GCS. Read the files comments to know how to configure each. Run the next commands to install a minio on admin cluster using the Helm package manager

helm repo add codecentric https://codecentric.github.io/helm-charts
helm repo update
with PVC
helm upgrade --install -n minio -f minio\eva-minio-values.yaml minio minio/minio --version 7.0.2
with GCS
helm upgrade --install -n minio -f minio\eva-minio-values.yaml minio minio/minio --version 7.0.2 --set-file gcsgateway.gcsKeyJson=minio/gcsKey.json

4. In this step, execute the following commands to install the Minio chart archive:

helm repo add minio https://helm.min.io/
helm repo update
helm upgrade --install -n minio -f minio\eva-minio-values.yaml minio minio/minio --version 7.0.2

5. Install eva-admin-rabbitmq-server chart:

 helm upgrade --install eva-admin-rabbitmq-server .

6. Before executing, make sure that eva-rabbitmq-server pod is deployed successfully. Install eva-admin-rabbitmq-config chart:

 helm upgrade --install eva-admin-rabbitmq-config .

7. Install eva-admin-config-server chart:

 helm upgrade --install eva-admin-config-server .

8. Before executing, make sure that eva-config-server pod is deployed successfully. Install eva-admin-config-server-post chart:

 helm upgrade --install eva-admin-config-server-post .

9. We'll need to setup clever-system user in our keycloak, so install the eva-admin-keycloak-realm-post chart:

  helm upgrade --install eva-admin-keycloak-realm-post .

10. Install eva-admin-server chart:

 helm upgrade --install eva-admin-server .

Admin Configurations

Remember: before installing an instance, it is mandatory execute eva-instance-config-server-post chart into Admin cluster to apply configuration changes for an instance.

 helm upgrade --install eva-instance-config-server-post .

Remember: once the eva-instance-config-server-post chart has been released into admin cluster and before launching the instance charts, the next task is to register a new instance.

 helm upgrade --install eva-register-instance .

Instance Cluster

Once you have installed the admin cluster, execute in order, the following commands to deploy an eva INSTANCE helm charts for an eva instance cluster:

1. Install eva-instance-base-resources chart:

 helm upgrade --install eva-instace-base-resources .

Additionally, install the eva-admin-saas-resources chart if you're installing an eva-cloud solution. Once installed, the ingress spreading to GKE can be delayed for 5 to 10 minutes.

Remember, eva-admin-saas-resources must only be used in eva-cloud installations, and the following command should be ignored on eva-server installations.

 helm upgrade --install eva-instance-saas-resources .

2. Install eva-admin-rabbitmq chart

 helm upgrade --install eva-admin-rabbitmq .

Instance Configurations

Finally, execute the next commands to register and configure an organization and an environment for an instance:

helm upgrade --install eva-organization .
helm upgrade --install eva-environment .

Testing the charts

To debug templates, use the following options with the commands to have the server render the templates, and return the resulting manifest file:

helm upgrade --install eva-admin-base-resources . --dry-run --debug

To render chart templates locally and display the output, use the following command:

helm template .

To examine the chart for issues, use the following command:

helm lint .
