OpenShift Connector

Overview

OpenShift Connector extension provides an end-to-end developer experience for Red Hat® OpenShift®. Using this extension:

Developers can easily create, deploy and live debug container applications running on OpenShift.
Run local instance of OpenShift 4.9.0 using Red Hat CodeReady Containers.

Supported OpenShift Clusters

Developer Sandbox

The extension allows users free access to the Developer Sandbox for Red Hat OpenShift. From Add Cluster View, users will be redirected to the dev sandbox instance. The sandbox provides you with a private OpenShift environment in a shared, multi-tenant OpenShift cluster that is pre-configured with a set of developer tools.

Local instance of OpenShift

This extension can work with local or remote OpenShift clusters.

To provision local instance of OpenShift cluster, developers can use the following options:

Red Hat CodeReady Containers - run single node local OpenShift 4.x cluster

Public cloud providers

To install OpenShift Container Platform 4 in the public cloud, in your datacenter or on your laptop please visit Red Hat Hybrid Cloud console. Here are different scenarios to try OpenShift:

Red Hat OpenShift Cluster Manager - This 60-day, self-supported trial lets you install and run Red Hat OpenShift Container Platform on infrastructure you manage.
Red Hat OpenShift Dedicated - Red Hat OpenShift Dedicated is a fully managed service of Red Hat OpenShift on Amazon Web Services (AWS) and Google Cloud.
Microsoft Azure Red Hat OpenShift - Azure Red Hat OpenShift is a fully-managed service of Red Hat OpenShift on Azure, jointly engineered, managed and supported by Microsoft and Red Hat.

Core Concepts

Project: A project is your source code, tests, and libraries organized in a separate single unit
Application: An application is a program designed for end users. An application consists of multiple microservices or components that work individually to build the entire application. Examples of applications: e-Shop, Hotel Reservation System, Online Booking
Component: A component is a set of Kubernetes resources which host code or data. Each component can be run and deployed separately. Examples of components: Warehouse API Backend, Inventory API, Web Frontend, Payment Backend
Service: A service is software that your component links to or depends on. Examples of services: MariaDB, MySQL
Devfile: A devfile is a portable YAML file containing the definition of a component and its related URLs, storages and services.

Commands and Features

The extension supports a number of commands to interact with OpenShift clusters and resources. The commands are accessible via the command palette (Cmd+Shift+P ⌘⇧P on macOS or Ctrl+Shift+P ⌃⇧P on Windows and Linux), Visual Studio Code View title buttons and tree context menus.

Commands Available in OpenShift Application Explorer View

Commands for a Component

Components can be in one of 3 states:

no context - When there is no context folder associated with the component in the workspace.

Components in different states have different set of commands available.

Commands for a `pushed` Component

New URL - Expose Component to the outside world. The URLs that are generated using this command, can be used to access the deployed Components from outside the Cluster. Push the component to reflect the changes on the cluster.
New Storage - Create Storage and mount to a Component. Push the component to reflect the changes on the cluster.
Describe - Describe the given Component in terminal window or inside a webview editor.

Link Component - Link Component to another Component.
Link Service - Link Component to a Service.
Unlink - Unlink Component from Component/Service.
Open in Browser - Open the exposed URL in default browser.
Push - Push the source code to a Component.
Watch - Watch for changes, update Component on change.
Undeploy - Undeploys a Component from the cluster. The component still resides in the local config.
Debug - Debug local Java, Node.js and Python Component.
Test - Run test for the Component in cluster.
Reveal in Explorer - Show Component's context folder in Explorer view
Delete - Delete existing Component from the cluster and removes the local config also.

Commands for a `not pushed` Component

New URL - Expose Component to the outside world. The URLs that are generated using this command, can be used to access the deployed Components from outside the Cluster.
New Storage - Create Storage and mount to a Component. Push the component to reflect the changes on the cluster.
Describe - Describe the given Component in terminal window or inside a webview editor.
Push - Push the source code to a Component.
Delete - Delete existing Component the local configuration and remove context from workspace.

Commands for a `no context` Component

Describe - Describe the given Component in terminal window or inside a webview editor.
Import - If the component was created using old version of the extension (<=0.0.23), users can use the Import action to migrate to latest version and import the metadata changes.
Delete - Delete existing Component from the cluster.

Commands for a URL in a Component

Delete - Delete a URL from a Component.
Open URL - Open the specific URL in Browser.
Describe - Describe the given URL for the Component in terminal window.

Commands for a Storage

Delete - Delete a Storage from a Component.

Commands for a Service

Describe - Describe a Service Type for a selected Component
Delete - Delete a Service from an Application

NOTE: Currently we support creation of one component per folder. Multiple components from a folder might be supported in future releases.

Running OpenShift Locally

The extension provides a view to run local instance of OpenShift. To open the view use Add OpenShift Cluster button from OpenShift: Application Explorer view title.

The view guides you through the steps required to create and start OpenShift 4 single node cluster on your workstation using Red Hat CodeReady Containers:

Download & Configure Red Hat CodeReady Containers
Set Virtual Machine parameters: number of CPUs and memory limit
Setup Red Hat CodeReady Containers
Run Red Hat CodeReady Containers commands to setup/start the cluster

The view provides following options to control cluster's state:

Start cluster
Stop cluster
Open OpenShift Developer Console for cluster
Refresh cluster's state

Debug Support

OpenShift: Debug command simplifies the way to start debugging for OpenShift Components pushed to a cluster. It supports following devfile components: Node.js, Java and Python (including Django)

Debug Node.js Component

Default Visual Studio Code installation includes JavaScript/TypeScript Language Support and Debugger Extensions required to debug a Node.js Component. That means new OpenShift: Debug command can be used without installing any additional extensions.

Debug Java Component

To debug a Java Component, Java Language Support and Java Debugger Extensions are required. OpenShift Connector extension will prompt the user to install missing extension(s) before it starts Debugger for a Java Component.

Breaking Changes Between Previous Releases

Updating from release `0.0.23` or earlier

The Components created with previous versions(<=0.0.23) will no longer be visible in OpenShift Application Explorer view.
The Extension will prompt the user to specify the context folder when creating new Components and then add selected folder to workspace.
New Component, Url and Storage objects are created locally in context folder and not immediately pushed to the cluster.

Please follow the migration guide to resolve any possible issues.
