In this section, we describe on how you can install Helm Dashboard by Devtron without any integrations. Integrations can be added later using Devtron Stack Manager.

If you want to install Devtron on Minikube, Microk8s, K3s, Kind, refer this section.

Before you begin

Install Helm if you have not installed it.

Add Helm Repo

helm repo add devtron https://helm.devtron.ai

Update Helm Repo

helm repo update devtron

Install Helm Dashboard by Devtron

Note: This installation command will not install CI/CD integration. For CI/CD, refer install Devtron with CI/CD section.

Run the following command to install Helm Dashboard by Devtron:

helm install devtron devtron/devtron-operator \
--create-namespace --namespace devtroncd

Install Multi-Architecture Nodes (ARM and AMD)

To install Devtron on clusters with the multi-architecture nodes (ARM and AMD), append the Devtron installation command with --set installer.arch=multi-arch.

Devtron Dashboard

Run the following command to get the dashboard URL:

kubectl get svc -n devtroncd devtron-service -o jsonpath='{.status.loadBalancer.ingress}'

You will get the result something as shown below:

[test2@server ~]$ kubectl get svc -n devtroncd devtron-service -o jsonpath='{.status.loadBalancer.ingress}'
[map[hostname:aaff16e9760594a92afa0140dbfd99f7-305259315.us-east-1.elb.amazonaws.com]]

The hostname aaff16e9760594a92afa0140dbfd99f7-305259315.us-east-1.elb.amazonaws.com as mentioned above is the Loadbalancer URL where you can access the Devtron dashboard.

You can also do a CNAME entry corresponding to your domain/subdomain to point to this Loadbalancer URL to access it at a custom domain.

Devtron Admin credentials

When you install Devtron for the first time, it creates a default admin user and password (with unrestricted access to Devtron). You can use that credentials to log in as an administrator.

After the initial login, we recommend you set up any SSO service like Google, GitHub, etc., and then add other users (including yourself). Subsequently, all the users can use the same SSO (let's say, GitHub) to log in to Devtron's dashboard.

The section below will help you understand the process of getting the administrator credentials.

For Devtron version v0.6.0 and higher

Username: admin Password: Run the following command to get the admin password:

kubectl -n devtroncd get secret devtron-secret \
-o jsonpath='{.data.ADMIN_PASSWORD}' | base64 -d

kubectl -n devtroncd get secret devtron-secret \
-o jsonpath='{.data.ACD_PASSWORD}' | base64 -d

Note: If you want to uninstall Devtron or clean Devtron helm installer, refer our uninstall Devtron.

Upgrade

To use the CI/CD capabilities with Devtron, you can Install the Devtron with CI/CD or Devtron with CI/CD along with GitOps (Argo CD).

You can configure Devtron by using configuration files. Configuration files are YAML files which are user-friendly. The configuration allows you to quickly roll back a configuration change if necessary. It also aids cluster re-creation and restoration.

There are two ways you can perform configurations while setting up Devtron dashboard:

• Installation Configurations

• Override Configurations

You can also setup ingress while setting up Devtron dashboard. Refer here for ingress setup.

kubectl -n devtroncd get installers installer-devtron -o jsonpath='{.status.sync.status}'

pod=$(kubectl -n devtroncd get po -l app=inception -o jsonpath='{.items[0].metadata.name}')&& kubectl -n devtroncd logs -f $pod

cd devtron-installation-script/
kubectl delete -n devtroncd -f yamls/
kubectl -n devtroncd patch installer installer-devtron --type json -p '[{"op": "remove", "path": "/status"}]'

Still facing issues, please reach out to us on Discord.

In this section, we describe the steps in detail on how you can install Devtron with CI/CD integration.

Prerequisites

Once ingress setup for devtron is done and you want to run Devtron over https, you need to add different annotations for different ingress controllers and load balancers.

1. Nginx Ingress Controller

In case of nginx ingress controller, add the following annotations under service.annotations under nginx ingress controller to run devtron over https.

(i) Amazon Web Services (AWS)

If you are using AWS cloud, add the following annotations under service.annotations under nginx ingress controller.

(ii) Digital Ocean

If you are using Digital Ocean cloud, add the following annotations under service.annotations under nginx ingress controller.

2. AWS Application Load Balancer (AWS ALB)

In case of AWS application load balancer, add following annotations under ingress.annotations to run devtron over https.

3. Azure Application Gateway

In case of AWS application load balancer, the following annotations need to be added under ingress.annotations to run devtron over https.

For an Ingress resource to be observed by AGIC (Application Gateway Ingress Controller) must be annotated with kubernetes.io/ingress.class: azure/application-gateway. Only then AGIC will work with the Ingress resource in question.

Note: Make sure NOT to use port 80 with HTTPS and port 443 with HTTP on the Pods.

To uninstall Devtron, run the following command:

This command will remove all the namespaces related to Devtron (devtroncd, devtron-cd, devtron-ci etc.).

Reference

Overview

The Kubernetes client by Devtron is a very lightweight dashboard that can be installed on arm64/amd64-based architectures. It comes with the features such as Kubernetes Resources Browser and Cluster Management that can provide control and observability for resources across clouds and clusters.

Devtron Kubernetes client is an intuitive Kubernetes Dashboard or a command line utility installed outside a Kubernetes cluster. The client can be installed on a desktop running on any Operating Systems and interact with all your Kubernetes clusters and workloads through an API server. It is a binary, packaged in a bash script that you can download and install by using the following set of commands.

By installing Devtron Kubernetes Client, you can access:

Here are a few advantages of using Devtron Kubernetes Client:

• Managing Kubernetes Resources at scale: Clusters vary on business and architectural needs. Organizations tend to build smaller clusters for more decentralization. This practice leads to the creation of multiple clusters and more nodes. Managing them on a CLI requires multiple files, making it difficult to perform resource operations. But with the Devtron Kubernetes Client, you can gain more visibility into K8s resources easily.

• Unifying information in one place: When information is scattered across clusters, and you have to type commands with arguments to fetch desired output, the process becomes slow and error-prone. Without a single point of configuration source, the configurations of different config. files diverge, making them even more challenging to restore and track. The Devtron Kubernetes Client unifies all the information and tools into one interface to perform various contextual tasks.

• Accessibility during an outage for troubleshooting: As the Devtron Kubernetes Client runs outside a cluster, you can exercise basic control over their failed resources when there is a cluster-level outage. The Client helps to gather essential logs and data to pinpoint the root cause of the issue and reduce the time to restore service.

• Avoiding Kubeconfig version mismatch errors: With the Devtron Kubernetes Client, you can be relieved from maintaining the Kubeconfig versions for the respective clusters (v1.16 - 1.26 i.e, current version) as the Devtron Kubernetes Client performs self kubeconfig version control. Instead of managing multiple kubectl versions manually, it eliminates the chances of errors occurring due to the mismatch in configuration.

Install Devtron Kubernetes Client

• Download the bash script using the below URL: https://cdn.devtron.ai/k8s-client/devtron-install.bash

• To automatically download the executable file and to open the dashboard in the respective browser, run the following command:

Note: Make sure you place Devtron-install.bash in your current directory before you execute the command.

• Devtron Kubernetes Client opens in your browser automatically.

Note: You do not need to have a super admin permission to add a cluster if you install Devtron Kubernetes Client. You can add more than one cluster.

Kubernetes Resource Browser

Kubernetes Resource Browser provides a graphical user interface for interacting and managing all your Kubernetes (k8s) resources across clusters. It also helps you to deploy and manage Kubernetes resources and allows pod operations such as:

• View real-time logs

• Check manifest and edit live manifests of k8s resources

• Executable via terminal

• View Events

• Or, delete a resource

With Kubernetes Resource browser, you can also perform the following:

• Check the real-time health status

• Search for any workloads

• Manage multiple clusters and change cluster contexts

• Deploy multiple K8s manifests through Create UI option.

• Perform resource grouping at the cluster level.

Note: You do not need to have a super admin permission to access Kubernetes Resource Browser if you install Devtron Kubernetes Client.

Cluster Management

With the Devtron Kubernetes Client, you can manage all your clusters running on-premises or on a cloud. It is a cluster and cloud agnostic platform where you can add as many clusters as you want, be it a lightweight cluster such as k3s/ microk8s or cloud managed clusters like Amazon EKS.

It enables you to observe and monitor the cluster health and real-time node conditions. The Cluster management feature provides a summary of nodes with all available labels, annotations, taints, and other parameters such as resource usage. In addition to that, it helps you to perform node operations such as:

• Debug a node

• Cordon a node

• Drain a node

• Taint a node

• Edit a node config

• Delete a node

Some Peripheral Commands

• In case if you close the browser by mistake, you can open the dashboard by executing the following command. It will open the dashboard through a port in the available web browser and store the Kubernetes client's state.

• To stop the dashboard, you can execute the following command:

• To update the Devtron Kubernetes Client, use the following command. It will stop the running dashboard and download the latest executable file and open it in the browser.

In certain cases, you may want to override default configurations provided by Devtron. For example, for deployments or statefulsets you may want to change the memory or CPU requests or limit or add node affinity or taint tolerance. Say, for ingress, you may want to add annotations or host. Samples are available inside the directory.

To modify a particular object, it looks in namespace devtroncd for the corresponding configmap as mentioned in the mapping below:

apiVersion, kind, metadata.name in the multiline string is used to match the object which needs to be modified. In this particular case it will look for apiVersion: extensions/v1beta1, kind: Ingress and metadata.name: devtron-ingress and will apply changes mentioned inside update: as per the example inside the metadata: it will add annotations owner: app1 and inside spec.rules.http.host it will add http://change-me.

Once we have made these changes in our local system we need to apply them to a Kubernetes cluster on which Devtron is installed currently using the below command:

Run the following command to make these changes take effect:

Our changes would have been propagated to Devtron after 20-30 minutes.

Recommended Resources for Production use

The overall resources required for the recommended production overrides are:

The production overrides can be applied as pre-devtron installation as well as post-devtron installation in the respective namespace.

Pre-Devtron Installation

If you want to install a new Devtron instance for production-ready deployments, this is the best option for you.

Create the namespace and apply the overrides files as stated above:

After files are applied, you are ready to install your Devtron instance with production-ready resources.

Post-Devtron Installation

If you have an existing Devtron instance and want to migrate it for production-ready deployments, this is the right option for you.

In the existing namespace, apply the production overrides as we do it above.

Host URL is the domain address at which your devtron dashboard can be reached.

Add Host URL

To add host URL, go to the Host URL section of Global Configurations.

On the Host URL page:

• Enter the host URL in the Host URL field.

• Or, you can select auto-detect from your browser.

• Next, click Update.

A global configuration allows you to easily share common configuration between multiple repositories without copy/pasting it to these repositories.

Before you start creating an application, we recommend to provide basic information in different sections of Global Configurations available in Devtron.

Regular backups for Devtron PostgreSQL and ArgoCD are crucial components of a disaster recovery plan, as they protect against potential data loss due to unforeseen circumstances. This documentation provides instructions on how to take backups of Devtron and store them either on AWS S3 or Azure containers.

1. Go to the devtron chart store and search for devtron-backups chart.

1. Select the devtron-backups and click Configure & Deploy.

2. Now follow either of the options described below according to your Cloud provider.

AWS S3 Backup

To store Devtron backups on AWS S3, please follow these steps:

1. Create an S3 bucket to store the Devtron backup, you can configure the bucket to delete all the objects older than 15/30 days.

2. Create a user with sufficient permissions to push to the S3 bucket created in step 1.

3. Obtain the access key and secret access key for the created user.

4. Configure the devtron-backups chart for AWS S3 by selecting the appropriate options:

1. Deploy the chart, and the Devtron backup will be automatically uploaded to the AWS S3 bucket at the scheduled intervals.

Azure Containers Backup

To store Devtron backups on Azure Containers, please follow these steps:

1. Create a storage account in Azure.

2. Within the storage account, create two containers for the Devtron backup.

3. Navigate to Security + Networking > Access Key section in Azure and copy the Access Key:

1. Configure the devtron-backups chart for Azure Containers by providing the Access Key:

1. Before deploying the backup chart, ensure that AWS.enabled is set to false. This will ensure that Devtron backup will be automatically uploaded to the configured Azure containers on the scheduled intervals.

By following these steps, you can ensure that your Devtron data is securely backed up and protected against any potential data loss, enabling you to recover quickly in case of emergencies.

Configure Secrets

For Helm installation this section refers to secrets section of values.yaml.

Configure the following properties:

Configure ConfigMaps

For Helm installation this section refers to configs section of values.yaml.

Configure the following properties:

Configure Resources

Devtron provides ways to control how much memory or CPU can be allocated to each Devtron microservice. You can adjust the resources that are allocated to these microservices based on your requirements. The resource configurations are available in following sizes:

Small: To configure the small resources (e.g. to manage less than 10 apps on Devtron ) based on the requirements, append the Devtron installation command with -f https://raw.githubusercontent.com/devtron-labs/devtron/main/charts/devtron/resources-small.yaml.

Configure Overrides

For Helm installation this section refers to customOverrides section of values.yaml. In this section you can override values of devtron-cm which you want to keep persistent. For example:

You can configure the following properties:

Storage for Logs and Cache

AWS SPECIFIC

While installing Devtron and using the AWS-S3 bucket for storing the logs and caches, the below parameters are to be used in the ConfigMap.

NOTE: For using the S3 bucket it is important to add the S3 permission policy to the IAM role attached to the nodes of the cluster.

The below parameters are to be used in the Secrets :

AZURE SPECIFIC

While installing Devtron using Azure Blob Storage for storing logs and caches, the below parameters will be used in the ConfigMap.

GOOGLE CLOUD STORAGE SPECIFIC

While installing Devtron using Google Cloud Storage for storing logs and caches, the below parameters will be used in the ConfigMap.

To convert string to base64 use the following command:

Note:

1. Ensure that the cluster has read and write access to the S3 buckets/Azure Blob storage container mentioned in DEFAULT_CACHE_BUCKET, DEFAULT_BUILD_LOGS_BUCKET or AZURE_BLOB_CONTAINER_CI_LOG, or AZURE_BLOB_CONTAINER_CI_CACHE.

2. Ensure that the cluster has read access to AWS secrets backends (SSM & secrets manager).

We can use the --set flag to override the default values when installing with Helm. For example, to update POSTGRESQL_PASSWORD and BLOB_STORAGE_PROVIDER, use the install command as:

Configuration of Blob Storage

Blob Storage allows users to store large amounts of unstructured data. Unstructured data is a data that does not adhere to a particular data model or definition, such as text or binary data. Configuring blob storage in your Devtron environment allows you to store build logs and cache.

In case, if you do not configure the Blob Storage, then:

• You will not be able to access the build and deployment logs after an hour.

• Build time for commit hash takes longer as cache is not available.

• Artifact reports cannot be generated in pre/post build and deployment stages.

You can configure Blob Storage with one of the following Blob Storage providers given below:

Note: You can also use the respective following command to switch to another Blob Storage provider. As an example, If you are using MinIO Storage and want to switch to Azure Blob Storage, use the command provided on the Azure Blob Storage tab to switch.

Secrets

ConfigMaps

Dashboard Configurations

Authorization section describes how to authenticate and authorize access to resources, also managing role-based access levels in Devtron.

Access can be granted to a user via:

• SSO Login Services

• User Permissions

• Permission Groups

• API Tokens

Once Devtron is installed, it has a built-in admin user with super admin privileges with unrestricted access to all Devtron resources. We recommended to use a user with super admin privileges for initial and global configurations only and then switch to local users or configure SSO integration.

Only users with super-admin privileges can create SSO configuration. Devtron uses Dex for authenticating a user against the identity provider.

To add/edit SSO configuration, go to the SSO Login Services section of Global Configurations.

Supported SSO Providers

Below are the SSO providers which are available in Devtron. Select one of the SSO providers (e.g., GitHub) to configure SSO:

Google GitHub GitLab Microsoft LDAP OpenID Connect OpenShift

Dex implements connectors that target specific identity providers for each connector configuration. You must have a created account for the corresponding identity provider and registered an app for client key and secret.

Refer the following documents for more detail.

• https://dexidp.io/docs/connectors/

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

1. Create new SSO Configuration

Make sure that you have a super admin access.

• Go to the Global Configurations → SSO Login Services and click any SSO Provider of your choice.

• In the URL field, enter the valid Devtron application URL where it is hosted.

• For providing redirectURI or callbackURI registered with the SSO provider, you can either select Configuration or Sample Script.

• Provide the client ID and client Secret of your SSO provider (e.g. If you select Google as SSO provider, then you must enter $GOOGLE_CLIENT_ID and $GOOGLE_CLIENT_SECRET in the client ID and client Secret respectively.)

• Select Save to create and activate SSO Login Service.

Note:

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

• Except for the domain substring, URL and redirectURI remains same.

2. Update SSO Configuration

You can change SSO configuration anytime by updating the configuration and click Update. Note: In case of configuration change, all users will be logged out of Devtron and will have to login again.

3. Configuration Payload

• type : Any platform name such as (Google, GitLab, GitHub etc.)

• name : Identity provider platform name

• id : Identity provider platform which is a unique ID in string. (Refer to dexidp.io

• config : User can put connector details for this key. Platforms may not have same structure but common configurations are clientID, clientSecret, redirectURI.

• hostedDomains : Domains authorized for SSO login.

Next Steps

After configuring an SSO for authentication, you need to add users in Devtron, else your users won't be able to log in via SSO.

In case you have enabled auto-assign permissions in Microsoft or LDAP, relevant permission groups must also exist in Devtron for a successful login.

External Links allow you to connect to the third-party applications within your Devtron dashboard for seamlessly monitoring/debugging/logging/analyzing your applications. You can select from the pre-defined third-party applications such as Grafana to link to your application for quick access.
