Developer Preview FAQ

Overview

During the {product-title} (Next Gen) Developer Preview, consult the following sections for frequently asked questions and current usage considerations during the preview period.

Product

HOW IS THE NEXT GEN DEVELOPER PREVIEW DIFFERENT THAN OPENSHIFT ONLINE?

{product-title} currently runs on the {product-title} 2.X platform. The Next Gen Developer Preview brings {product-title} 3, built on Docker and Kubernetes, to the public cloud in a multi-tenant environment. Learn more.

WHAT HAPPENS TO MY OPENSHIFT ONLINE (V2) ACCOUNT WHEN NEXT GEN (V3) GOES INTO PRODUCTION?

At this time, the current (v2) and next generation (v3) platforms will be available in parallel. As the {product-title} (Next Gen) platform matures, we will publish a sunset plan for the current (v2) offering and provide you with adequate time to migrate your applications to the new platform.

WHAT ARE THE RESOURCE LIMITS DURING THE DEVELOPER PREVIEW?

Each user can create a single project with up to 2 GiB memory, 4 CPU cores, and 2 x 1 GiB persistent volumes. For more detailed limits, see the Settings tab on your project’s Overview page in the web console.

HOW LONG WILL I HAVE ACCESS TO THE ENVIRONMENT?

You will have access to the {product-title} (Next Gen) Developer Preview environment for 30 days, at which point your account will expire.

WHAT HAPPENS WHEN MY ACCOUNT EXPIRES?

Your account, applications, and data will be permanently deleted to free up resources for other users when your account expires. This means that you will no longer be able to log in to the web console, authenticate using the {product-title} CLI tools, or access your applications and related data.

CAN I CREATE A NEW ACCOUNT AFTER MY ACCOUNT EXPIRES?

If you are interested in trying the {product-title} (Next Gen) Developer Preview again, just complete the registration form after your account expires and we will provision a fresh set of resources for you as soon as they become available.

WHAT LANGUAGES AND DATABASE SERVICES ARE SUPPORTED?

The {product-title} (Next Gen) Developer Preview currently supports a number of developer languages and database services, including JBoss Middleware services.

See the OpenShift features page for the list of available languages and services.

CAN USERS RUN IMAGES FROM DOCKER HUB OR PUSH THEIR OWN IMAGES TO THE REGISTRY?

Yes, but with a few caveats. For security reasons, no images that run processes as root are allowed. Additionally, any Dockerfile VOLUME instruction must be mounted with either a persistent volume claim (PVC) or an emptyDir at this time. See more considerations.

CAN I RUN PRODUCTION SERVICES ON THE DEVELOPER PREVIEW?

The Developer Preview is a time bound environment which can be used for prototyping or experimenting. We recommend that users do not deploy any production workloads. However, you can deploy a copy of your production workload to see how it performs in the environment.

Pricing

HOW AM I BILLED?

During our Developer Preview period, {product-title} (Next Gen) is FREE!

ARE PAID PLANS AVAILABLE FOR OPENSHIFT (NEXT GEN)?

Not at this time. {product-title} (Next Gen) will offer paid tiers when the offering becomes generally available.

Operations

WHAT IS YOUR SLA?

During our Developer Preview period, we do not offer a Service Level Agreement (SLA).

HOW CAN I FIND OUT ABOUT PRODUCT UPDATES AND SCHEDULED MAINTENANCE?

Red Hat will provide updates via status.preview.openshift.com.

Support

HOW CAN I RECEIVE SUPPORT FOR THE OFFERING?

During the Developer Preview there are no paid or official support channels, however, you can contact the Community Enablement team, create a bug report in Bugzilla, or create a post in the {product-title} Forums.

HOW SHOULD I REACH THE COMMUNITY ENABLEMENT TEAM OR USER FORUMS?

The best way to contact the community enablement team is to log a request in the Developer Portal. Make sure that you select "Developer Preview" in the Reason for contact drop down.

If you would like to ask a larger group of people for help, including {product-title} users, engineers, and operations team members, you can ask a question using the {product-title} Forums. Make sure to use the "dev-preview" tag when creating a new post.

WHAT SHOULD I DO WHEN I FIND A BUG?

Red Hat’s Bugzilla instance can be used to log bug reports (Product=OpenShift Online, Version=3.x). You can find a list of known and reported issues in Red Hat’s Bugzilla instance.

HOW DO I REPORT SECURITY FLAWS?

Red Hat’s Bugzilla instance can also be used to log security sensitive bug reports (Product=OpenShift Online, Version=3.X, Groups=security) by selecting the "Security Sensitive Bug" flag (automatically selected with the provided link).

Current Usage Considerations

The {product-title} (Next Gen) Developer Preview offering scopes the inventory of images it provides out of the box with a few considerations in mind, which also apply to any images you choose to import into your project. These conditions are enforced via the {product-title} quotas, limit ranges, and compute resources systems.

  • A memory limit of 2 GiB is in place for a project. The 2 GiB is spread out across the project’s pods and containers. Individual pods and containers have a limit of 1 GiB each.

  • Maximum counts are in place for pods, replication controllers, services, and secrets (though some amount of these secrets will be needed by the system’s build and deployer service accounts).

  • Any Dockerfile VOLUME instruction must be mounted with either a persistent volume claim (PVC) or an emptyDir at this time.

  • The project associated with a user can allocate up to two PVCs of up to 1 GiB each.

  • No images that run as root are allowed.

  • Only the Source-to-Image (S2I) build strategy is allowed for any build configurations imported into your project.

HOW DO I ACCESS THE INTERNAL REGISTRY?

The internal registry can be accessed at https://registry.preview.openshift.com. See Accessing the Internal Registry for more information.

HOW DO I CHECK MY CURRENT USAGE?

To check your project’s current resource usage, you can log into the web console and view them from the Settings tab of your project’s Overview, or use the following CLI command:

$ oc describe quota <your_project_quota_object_name>
WHAT ARE THE DEFAULT MEMORY LIMITS?

As part of providing a set of templates out of the box, various publicly accessible templates have been updated with a memory limit template parameter with a default setting for the deployments, with the 2 GiB memory limit in mind.

You can change the defaults when instantiating any given template as you see fit, based on the needs of the specific scenario you want to try. However, you must keep in mind the 2 GiB overall memory limit when adjusting the settings of your various deployments.

See Limit Ranges and Templates: Parameters for more information on these concepts.
