2.0.0 of odo has been released!

What's new​

Changes to the default deployment method​

Devfile is a file format that is used as odo's new deployment engine. Starting from 2.0.0 onwards, Source-to-Image (S2I) is no longer the default deployment method. S2I is still supported and can now be accessed with the --s2i flag from the command-line.

Learn how to deploy your first devfile using devfiles from our Devfile tutorial.

Example on how to download a starter project and deploy a devfile:

$ odo create nodejs --starter
Validation
 ✓  Checking devfile existence [22411ns]
 ✓  Checking devfile compatibility [22492ns]
 ✓  Creating a devfile component from registry: DefaultDevfileRegistry [24341ns]
 ✓  Validating devfile component [74471ns]

Starter Project
 ✓  Downloading starter project nodejs-starter from https://github.com/odo-devfiles/nodejs-ex.git [479ms]

Please use `odo push` command to create the component with source deployed

$ odo push

Validation
 ✓  Validating the devfile [132092ns]

Creating Kubernetes resources for component nodejs
 ✓  Waiting for component to start [5s]

Applying URL changes
 ✓  URL http-3000: http://http-3000-nodejs-foobar.myproject.example.com/ created

Syncing to component nodejs
 ✓  Checking files for pushing [1ms]
 ✓  Syncing files to the component [868ms]

Executing devfile commands for component nodejs
 ✓  Executing install command "npm install" [4s]
 ✓  Executing run command "npm start" [2s]

Pushing devfile component nodejs
 ✓  Changes successfully pushed to component

Deploying a custom Kubernetes controller with odo​

With the release of 2.0.0 deploying operators is now out of experimental mode.

Learn how to deploy your first Kubernetes custom controller from our installation guide.

Example on how to deploy your first Operator:

$ odo catalog list services
  Operators available in the cluster
  NAME                          CRDs
  etcdoperator.v0.9.4           EtcdCluster, EtcdBackup, EtcdRestore

$ odo service create etcdoperator.v0.9.4/EtcdCluster

odo debug is no longer in technical preview​

The odo debug command is no longer in technical preview.

Learn how to debug your component via the CLI or VSCode.
