Installation

Install Otomi with Helm

Add the Otomi repository

helm repo add otomi https://otomi.io/otomi-core
helm repo update

See helm repo for command documentation.

Minimal configuration**

cluster:
k8sVersion: "1.23" # currently 1.18, 1.19, 1.20, 1.21, 1.22 and 1.23 are supported
name: # the name of your cluster
provider: # choose between aws, azure, google, digitalocean or custom

Custom values

To view the required values.yaml file with detailed comments, view and download the chart's latest values.yaml. Run the following command to view all the values (which might be overwhelming):

helm show values otomi/otomi

To test wether the input values are correct run the following command:

helm template -f values.yaml otomi/otomi

Install the Chart

Install the chart with the following command:

helm install -f values.yaml otomi otomi/otomi

Monitoring the chart install

The chart deploys a Job (otomi) in the default namespace. Monitor the chart install using kubectl:

# get the status of the job
kubectl get job otomi -w
# watch the helm chart install status:
watch helm list -Aa

Or view detailed info about kubernetes resources with k9s

Installing from source

As an alternative, you can also clone the otomi-core source code from the Github and install otomi using the chart source code.

Download source

git clone https://github.com/redkubes/otomi-core.git
cd otomi-core

Install

Now customize the values.yaml file.

Use the following command to install the chart with the name my-otomi-release (a custom name that you choose).

helm install -f values.yaml my-otomi-release chart/otomi

Uninstalling Otomi

helm uninstall my-otomi-release

Doing a Helm uninstall will only remove the job used to deploy Otomi. It will not remove all the installed components. If you would like to do a complete uninstall, we advise to first clone the otomi/values repository (to secure the configuration) and then uninstall using Otomi CLI.

Optional Configuration

You can optionally configure Otomi to use an external IDP (Azure AD), use an external Key Management Service (KMS) provider for SOPS and use a DNS zone in combination with LetsEncrpt certificates. Below you can find detailed instructions on how to set up Azure AD as an external IDP and configure KMS. We will soon add more instructions for other IDPs, such as Amazon Incognito, Google Identity, and Okta.

Use DNS and Let's Encrypt

By default, Otomi uses the public IP address of the load balancer for nameresolving using nip.io. To use DNS with LetsEncrypt, follow these instructions:

To install Otomi with DNS and Let's Encrypt, use the following values:

otomi:
hasExternalDNS: true

# Configure cert-manager
apps:
cert-manager:
issuer: letsencrypt
stage: staging # defaults to 'production' when commented out

# Configure DNS
dns:
# domainFilters: []
# zoneIdFilters: []
# provider: # provide one of the following below: aws|azure|google
# aws:
# # next two keys are optional for explicit access with an iam role
# # (if no metadata exists with implicit role access to manage dns)
# accessKeySecret: ''
# secretAccessKey: ''
# # region is always needed
# region: eu-central-1
# role: '' # optional ARN, may be set explicitly if no metadata can be accessed
# azure:
# aadClientId: ''
# aadClientSecret: ''
# tenantId: '' # optional
# subscriptionId: '' # optional
# google:
# serviceAccountKey: ''
# project: ''

Use Azure AD as IDP

The authentication of brokered identities through Azure AD requires a service principal with certain Azure AD API permissions. An app registration needs to be created with the following API permissions:

API / Permission nameTypeDescription
Microsoft Graph / emailDelegatedView users' email address
Microsoft Graph / openidDelegatedSign users in
Microsoft Graph / profileDelegatedView users' basic profile
Microsoft Graph / User.ReadDelegatedSign in and read user profile

And the following token configurations:

ClaimDescriptionToken typeOptional settings
family_nameProvides the last name, surename, or family nameID-
given_nameProvides the first or "give" name of the userID-
groupsOptional formatting for group claimsID, Access, SAMLDefault
upnAn identifier for the user that can be used ...IDDefault

Note that the group type should be set to 'security groups'.

At the 'Authentication' tab you should be able to set the following callback URL§s and enable that both "Access tokens" and "ID tokens" are issued and public client flows are allowed:

  • https://keycloak.<dns-zone-name>/realms/master/broker/otomi-idp/endpoint
  • https://keycloak.<dns-zone-name>

To install Otomi with Azure Active Directory as IdP instead of (default) Keycloak, use the following values:

oidc:
clientID: ""
clientSecret: ""
issuer: ""
# IDP group id used to identify global admin
adminGroupID: ""
# IDP group id used to identify team admin
teamAdminGroupID: ""
note

otomi-idp is the default KeyCloak alias (shown as login title). To use another alias, add the following to the chart values:

apps:
keycloak:
idp:
alias: <your-alias>

Use KMS to manage keys for encryption

If you would like the secrets in the values repository to be encrypted, you will have to setup an account with your Key Management Service (KMS) provider. It is needed by sops, the tool used for encryption.

Find quickstart documentation below on how to setup KMS access per supported provider:

Follow the instructions of the provider of your choosing and jot down the credentials obtained for the next steps.

To install Otomi with SOPS/KMS, use the following values:

kms:
sops:
provider: "" # provider can be one of aws|azure|google|vault
# aws:
# keys: ''
# accessKey: ''
# secretKey: ''
# region: ''
# azure:
# keys: ''
# tenantID: ''
# clientID: ''
# clientSecret: ''
# google:
# keys: ''
# accountJson: ''
# project: ''
# vault:
# token: ''

But you can also enable SOPS/KMS after installing Otomi using Otomi Console.
