Why Devtron takes GitOps Configuration?

Devtron uses GitOps and stores configurations in git; Git Credentials can be entered at Global Configuration > GitOps which is used by Devtron for configuration management and storing desired state of the application configuration. In case GitOps is not configured, Devtron cannot deploy any application or charts.

Areas impacted by GitOps are:

• Deployment Template, click here to learn more.

• Charts, click here to learn more.

Overview

Once installed Devtron has one built-in admin user with super-admin privileges that has complete access to the system. It is recommended to use admin user only for initial and global configuration and then switch to local users or configure SSO integration.

Only users with super-admin privileges have access to create SSO configuration. Devtron uses dex for authenticating a user against the identity provider.

To add/edit SSO configuration please go to the left main panel -> Select Global Configurations -> Select SSO Login Services

Supported SSO Providers

LDAP GitHub OpenID Connect Google Microsoft OpenShift

Dex implements connectors that target specific identity providers, for each connector configuration user must have created account for the corresponding identity provider and registered an app for client key and secret. For examples see

• https://dexidp.io/docs/connectors/

• https://dexidp.io/docs/connectors/google/

1. Create new SSO Configuration

Login as a user with super-admin privileges and go to Global Configurations -> SSO Login Services and click on any Identity Provider and fill the configuration.

Add valid devtron application URL where it is hosted.

Fill correct redirect URL or callback URL from which you have registered with the identity provider in the previous step along with the client id and client secret shared by the identity provider.

Only single SSO login configuration can be active at one time. Whenever you create or update any SSO config, it will be activated and used by the system and previous configurations will be deleted.

Except for the domain substring, URL and redirectURI should be the same as in the screenshots.

Select Save to create and activate SSO login.

2. Update SSO Configuration

SSO configuration can be changed by the user at any later point in time by updating the configuration and clicking on the Save button at the bottom right. In case of configuration change all users will be logged out of the system and will have to login again.

3. Configuration Payload

• type : oidc or any platform name such as (google, gitlab, github etc)

• name : identity provider platform name

• id : identity provider platform unique id in string. (refer to dexidp.io)

• config : user can put connector details into this key. platforms may not have same structure but commons are clientID, clientSecret, redirectURI.

• hostedDomains : domains authorized for SSO login.

Container registries are used to store images built by the CI Pipeline. Here you can configure the container registry you want to use for storing images.

When configuring an application, you can choose which registry and repository it should use in the App Configuration > Docker Build Config section.

Add Container Registry configuration:

Go to the Container Registry section of Global Configuration. Click on Add container registry.

You will see below the input fields to configure the container registry.

• Name

• Registry type

  • ecr

    • AWS region

    • Access key ID

    • Secret access key

  • docker hub

    • Username

    • Password

  • Others

    • Username

    • password

• Registry URL

• Set as default

Name

Provide a name to your registry, this name will be shown to you in Docker Build Config as a drop-down.

Registry type

Here you can select the type of the Registry. We are supporting three types- docker hub, ecr and others. You can select any one of them from the drop-down. By default, this value is ecr. If you select ecr then you have to provide some information like- AWS region, Access Key, and Secret Key. If you select docker hub then you have to provide Username and Password. And if you select others then you have to provide the Username and Password.

Registry URL

Select any type of Registry from the drop-down, you have to provide the URL of your registry. Create your registry and provide the URL of that registry in the URL box.

Registry Type: ECR

To add an Amazon Elastic Container Registry (ECR), select the ECR Registry type. Amazon ECR is an AWS-managed container image registry service. The ECR provides resource-based permissions to the private repositories using AWS Identity and Access Management (IAM). ECR allows both Key-based and Role-based authentications.

Before you begin, create an IAM user, and attach only ECR policy ( AmazonEC2ContainerRegistryFullAccess ) if using Key-based auth. Or attach the ECR policy ( AmazonEC2ContainerRegistryFullAccess) to the cluster worker nodes IAM role of your Kubernetes cluster if using Role-based access.

To set this ECR as the default registry hub for your images, select [x] Set as default registry.

Select Save.

To use the ECR container image, go to the Applications page and select your application, and then select App Configuration > Docker Build Config.

Registry Type- Docker Hub

You have to provide the below information if you select the registry type as Docker Hub.

• Username

Give the username of the docker hub account you used for creating your registry in.

• Password

Give the password/token corresponding to your docker hub account.

Registry Type Others:

You have to provide the below information if you select the registry type as others.

• Username

Give the username of your account, where you have created your registry in.

• Password

Give the password corresponding to the username of your registry.

Set as default:

If you enable the Set as default option, then this registry name will be set as default in the Container Registry section inside the Docker build config page. This is optional. You can keep it disabled.

Advance Registry Url connection options:

• If you enable the Allow Only Secure Connection option, then this registry allows only secure connections.

• If you enable the Allow Secure Connection With CA Certificate option, then you have to upload/provide private CA certificate (ca.crt).

• If the container registry is insecure (for eg : SSL certificate is expired), then you enable the Allow Insecure Connection option.

Now click on Save to save the configuration of the Container registry.

Note:

You can use any registry which can be authenticated using docker login -u <username> -p <password> <registry-url>. However these registries might provide a more secured way for authentication, which we will support later. Some popular registries which can be used using username and password mechanism:

• Google Container Registry (GCR) : JSON key file authentication method can be used to authenticate with username and password. Please follow link for getting username and password for this registry. Please remove all the white spaces from json key and wrap it in single quote while putting in password field.

• Google Artifact Registry (GAR) : JSON key file authentication method can be used to authenticate with username and password. Please follow link for getting username and password for this registry. Please remove all the white spaces from json key and wrap it in single quote while putting in password field.

• Azure Container Registry (ACR) : Service principal authentication method can be used to authenticate with username and password. Please follow link for getting username and password for this registry.

Integrating With External Container Registry

If you want to use a private registry for container registry other than ecr, this will be used to push image and then create a secret in same environment to pull the image to deploy. To create secret, go to charts section and search for chart ‘dt-secrets’ and configure the chart. Provide an App Name and select the Project and Environment in which you want to deploy this chart and then configure the values.yaml as shown in example. The given example is for DockerHub but you can configure similarly for any container registry that you want to use.

name: regcred
type: kubernetes.io/dockerconfigjson
labels:
 test: chart
secrets:
 data:
   - key: .dockerconfigjson
     value: '{"auths":{"https://index.docker.io/v1/":{"username":"<username>","password":"<password>}}}'

The name that you provide in values.yaml ie. regcred is name of the secret that will be used as imagePullSecrets to pull the image from docker hub to deploy. To know how imagePullSecrets will be used in the deployment-template, please follow the documentation.

The Global configuration provides a feature of Cluster & Environment in which you can add your Kubernetes clusters and environment.

Select the Cluster & Environment section of global configuration and click on Add Cluster to add your cluster.

Add Cluster:

To add a cluster on devtron, you must have superadmin access.

Navigate to the Global Configurations → Clusters and Environments on devtron and click on Add Cluster. Provide the below informations to add your kubernetes cluster:

1. Name

2. Kubernetes Cluster Info

   • Server URL

   • Bearer token

3. Prometheus Info

   • Prometheus endpoint

     • Basic

       • Username

       • Password

     • Anonymous

   • TLS Key

   • TLS Certificate

1. Name

Give a name to your cluster inside the name box.

2. Kubernetes Cluster Info

Provide your kubernetes cluster’s credentials.

• Server URL

Provide the endpoint/URL of your kubernetes cluster.It is recommended to use a self-hosted URL instead of cloud hosted. Self-hosted URL will provide the following benefits.

(a) Disaster Recovery - It is not possible to edit the server-url of a cluster. So if you're using an eks url, For eg- *****.eu-west-1.elb.amazonaws.com it will be a tedious task to add a new cluster and migrate all the services one by one. While using a self-hosted url For eg- clear.example.com you can just point to the new cluster's server url in DNS manager and update the new cluster token and sync all the deployments.

(b) Easy cluster migrations - Cluster url is given in the name of the cloud provider used, so migrating your cluster from one provider to another will result in waste of time and effort. On the other hand, if using a self-hosted url migrations will be easy as the url is of single hosted domain independent of the cloud provider.

• Bearer token

Provide your kubernetes cluster’s Bearer token for authentication purposes so that Devtron is able to communicate with your kubernetes cluster and can deploy your application in your kubernetes cluster.

Get the server url and generate the bearer token by running the following command:

Please ensure that kubectl and jq are installed on the bastion on which you’re running the command.

3. Prometheus Info

Prometheus is a powerful solution to provide graphical insight into your application behavior. If you want to see your application matrix against your applications deployed in kubernetes, install Prometheus in your kubernetes cluster. The below inputs are required to configure your prometheus into Devtron’s tool.

• Prometheus endpoint

Provide the URL of your prometheus. Prometheus supports two types of authentication Basic and Anonymous. Select the authentication type for your Prometheus setup.

• Basic

If you select the basic type of authentication then you have to provide the Username and Password of prometheus for authentication.

• Anonymous

If you select Anonymous then you do not have to provide any username and password for authentication.

• TLS Key & TLS Certificate

TLS key and TLS certificate both options are optional, these options are used when you use a custom URL, in that case, you can pass your TLS key and TLS certificate.

K8s Version

on saving or update a cluster there is a call to fetch k8s version, it will store corresponding to cluster on db. used in listing api's and app detail page for grafana url.

Check the below screenshots to know how it looks like If you select the Basic authentication type

If you select the Anonymous authentication type

Now click on Save Cluster to save your cluster information.

Note:

Your kubernetes cluster gets mapped with the Devtron when you save your kubernetes cluster Configuration. Now the agents of devtron will be installed on your cluster so that the components of devtron can communicate to your cluster. When the agent starts installing on your cluster, you can check the status of the agents in the Cluster & Environment tab also.

Click on Details to check what got installed inside the agents. A new window will be popped up displaying all the details about these agents.

Add Environment

Once you have added your cluster in Cluster & Environment, you can add the environment also. Click on Add Environment, a window will be opened. Give a name to your environment in the Environment Name box and provide a namespace corresponding to your environment in the Namespace input box. Now choose if your environment is for Production purposes or for Non-production purposes. Production and Non-production options are only for tagging purposes. Click on Save and your environment will be created.

You can update an already created environment, Select and click on the environment which you want to update. You can only change Production and Non-production options here.

Note

You can not change the Environment name and Namespace name.

This is used to assign user to a particular group and user inherits all the permissions granted to this group. The Permission groups section contains a drop-down of all existing groups on which you have access. This is optional field and more than one groups can be selected for a user.

The advantage of the groups is to define a set of privileges like create, edit, or delete for the given set of resources that can be shared among the users within the group. Users can be added to an existing group to utilize the privileges that it grants. Any access change to group is reflected immediately in user access.

You can select the group which you are creating in the Group permissions section inside Add users.

1. Add new Group

Go to Global configurations -> Authorization -> Permission group and click on Add Group to create a new group.

Enter the Group Name and Description.

2. Create permission Group

Devtron includes predefined helm charts that cover the majority of use cases. For any use case not addressed by the default helm charts, you can upload your own helm chart and use it as a custom chart in Devtron.

• Who can upload a custom chart - Super admins

• Who can use the custom chart - All users

A super admin can upload multiple versions of a custom helm chart.

Prerequisites

1. A valid helm chart, which contains Chart.yaml file with name and version fields.

2. Image descriptor template file - .image_descriptor_template.json.

3. Custom chart packaged in the *.tgz format.

1. How to create a helm chart

2. Create the image descriptor template file - .image_descriptor_template.json

It's a GO template file that should produce a valid JSON file upon rendering. This file is passed as the last argument in helm install -f myvalues.yaml -f override.yaml command.

Place the .image_descriptor_template.json file in the root directory of your chart.

You can use the following variables in the helm template (all the placeholders are optional):

The values from the CD deployment pipeline are injected at the placeholder specified in the .image_descriptor_template.json template file.

For example:

To create a template file to allow Devtron to only render the repository name and the tag from the CI/CD pipeline that you created, edit the .image_descriptor_template.json file as:

3. Package the custom chart in the *.tgz format

Before you begin, ensure that your helm chart includes both Chart.yaml (with name and version fields) and .image_descriptor_template.json files.

The helm chart to be uploaded must be packaged as a versioned archive file in the format - <helm-chart-name>-vx.x.x.tgz.

The above command will create a my-custom-chart-0.1.0.tgz file.

Uploading a custom chart

A custom chart can only be uploaded by a super admin.

• On the Devtron dashboard, select Global Configurations > Custom charts.

• Select Import Chart.

• Choose Select tar.gz file... and upload the packaged custom chart in the *.tgz format.

The chart is being uploaded and validated. You may also Cancel upload if required.

Validation

The uploaded archive will be validated against:

• Supported archive template should be in *.tgz format.

• Chart.yaml must include the name and the version number.

• image_descriptor_template.json file should be present and the field format must match the format listed in the image builder template section.

The following are the validation results:

View the custom charts

All users can view the custom charts.

To view a list of available custom charts, go to Global Configurations > Custom charts page.

• The charts can be searched with their name, version, or description.

Use the custom chart in an application

Info:

This documentation consists of the Global Configurations available in Devtron.

Parts of the Documentation

This documentaion consist of authorizations available in Devtron

Parts of the documentaion

Like any enterprise product, Devtron supports fine grained access control to the resources based on

1. Type of action allowed on the Devtron resources (Create Vs View)

2. Sensitivity of the data (Editing image Vs Editing memory)

Access can be added to the User either directly or via Groups.

Role-based Access Levels

Devtron supports 5 levels of access:

1. View: User with view only access has the least privilege. This user can only view combination of environments, applications and helm charts on which access has been granted to the user. This user cannot view sensitive data like secrets used in applications or charts.

2. Build and Deploy: In addition to view privilege mentioned in above, user with build and deploy permission can build and deploy the image of permitted applications and helm charts to permitted environments.

3. Admin: User with admin access can create, edit, delete and view permitted applications in permitted projects.

4. Manager: User with manager access can do everything that an admin type user can do, in addition they can also give and revoke access of users for the applications and environments of which they are manager.

5. Super Admin: User with super admin privilege has unrestricted access to all Devtron resources. Super admin can create, modify, delete and view any Devtron resource without any restriction; its like Superman without the weakness of Kryptonite. Super Admin can also add and delete user access across any Devtron resource, add delete git repository credentials, container registry credentials, cluster and environment.

3. Select an Expiration date for the token(7 days, 30 days, 60 days, 90 days, custom and no expiration) To select a custom expiration date, select Custom from the drop-down. This will pop-up a calender from where you can select your custom expiration date for the API token.

4. Assign permissions to the token. To generate a token with super admin permission, select super admin permission. Or select specific permission if you want to generate a token with a specific role over a particular Devtron app or Helm app or chart group.

5. Now click on Generate Token.

A pop-up window will appear over the screen from where you can copy the API token.

Use API Token

Once devtron api token has been generated, you can use this token to hit devtron apis using any api testing tool like Jmeter, postman, citrus. Using postman here.

Open postman. Enter the request URL with POST method and under HEADERS, enter the API token as shown in the image below.

Now, under body, provide the api payload as shown below and click on Send.

As soon as you click on send, the create application api will be triggered and a new devtron app will be created as you mentioned in the payload.

Update API Token

To set a new expiration date or to make changes in permissions assigned to the token, we need to update the API token. To update the API token, click over the token name or click on the edit icon.

Delete API Token

To delete an API token, click on the delete icon. Any applications or scripts using this token will no longer be able to access the Devtron API.

Hurray! Your Devtron stack is completely setup. Let's get started by deploying a simple application on it.

This is a sample Nodejs application which we are going to deploy using Devtron. For a detailed step-wise procedure, please have a look at the link below -

Getting Started with Deploying application through devtron

External links allow you to connect to the third-party Monitoring Tools within your Devtron dashboard for seamlessly monitoring/debugging/logging/analyzing your applications. The Monitoring Tool is available as a bookmark at various component levels, such as application, pods, and container.

Use case

To monitor/debug an application using a specific Monitoring Tool (such as Grafana, Kibana, etc.), you may need to navigate to the tool's page, then to the respective app/resource page.

External links take you directly to the tool's page, which includes the context of the application, environment, pod, and container.

Prerequisites

Before you begin, configure an application in the Devtron dashboard.

• Super admin access*

• Monitoring tool URL

*External links can only be added/managed by a super admin, but other users can access the configured Monitoring tools on their app's page.

Add an external link

1. On the Devtron dashboard, select Global Configurations from the left navigation pane.

2. Select External links.

1. Select Add link.

2. On the Add link page, enter the following fields:

Note: To add multiple links, select + Add another at the top-left corner.

Select Save.

Access an external link

The users (admin and others) can access the configured external link from the App details page.

Manage external links

On this page, the configured external links can be filtered/searched, as well as edited/deleted.

Select Global Configurations > External links.

• Filter and search the links based on the tool's name or a user-defined name.

• Edit a link by selecting the edit icon next to an external link.

• Delete an external link by selecting the delete icon next to a link. The bookmarked link will be removed in the clusters for which it was configured.
