Just-in-time Access Controller

Just-in-time Access Controller enables users to request just-in-time (JIT) access to Kubernetes resources.

Description

The JIT Access Controller provides a mechanism for requesting and granting temporary, on-demand access to resources in Kubernetes clusters.

Getting Started

To get started, add the helm repository and install the chart.

Install helm repository:

helm repo add itsthatdude https://itsthatdude.github.io/helm-charts/`

Install the chart

kubectl create namespace jit-access-system
helm install jit-access itsthatdude/jit-access -n jit-access-system

See the Getting Started guide for more information

Development

Prerequisites

• go version v1.24.6+
• docker version 17.03+.
• kubectl version v1.11.3+.
• Access to a Kubernetes v1.11.3+ cluster.

To Deploy on the cluster

Build and push your image to the location specified by IMG:

make docker-build docker-push IMG=<some-registry>/jit-access:tag

NOTE: This image ought to be published in the personal registry you specified. And it is required to have access to pull the image from the working environment. Make sure you have the proper permission to the registry if the above commands don’t work.

Install the CRDs into the cluster:

make install

Deploy the Manager to the cluster with the image specified by IMG:

make deploy IMG=<some-registry>/jit-access:tag

NOTE: If you encounter RBAC errors, you may need to grant yourself cluster-admin privileges or be logged in as admin.

Create instances of your solution You can apply the samples (examples) from the config/sample:

kubectl apply -k config/samples/

NOTE: Ensure that the samples has default values to test it out.

To Uninstall

Delete the instances (CRs) from the cluster:

kubectl delete -k config/samples/

Delete the APIs(CRDs) from the cluster:

make uninstall

UnDeploy the controller from the cluster:

make undeploy

Project Distribution

Following the options to release and provide this solution to the users.

By providing a bundle with all YAML files

Build the installer for the image built and published in the registry

make build-installer IMG=<some-registry>/jit-access:tag

NOTE: The makefile target mentioned above generates an 'install.yaml' file in the dist directory.
This file contains all the resources built with Kustomize, which are necessary to install this project without its dependencies.

Using the installer

Users can just run kubectl apply -f <URL for YAML BUNDLE> to install the project, i.e.:

kubectl apply -f https://raw.githubusercontent.com/<org>/jit-access/<tag or branch>/dist/install.yaml

By providing a Helm Chart

Build the chart using the optional helm plugin

kubebuilder edit --plugins=helm/v2-alpha

See that a chart was generated under 'dist/chart', and users can obtain this solution from there

NOTE: If you change the project, you need to update the Helm Chart using the same command above to sync the latest changes. Furthermore, if you create webhooks, you need to use the above command with the '--force' flag and manually ensure that any custom configuration previously added to 'dist/chart/values.yaml' or 'dist/chart/manager/manager.yaml' is manually re-applied afterwards.
