Playground¶

Use IBM open labs¶

Connect to the IBM open lab home page, Select bring your own app to start a cluster with 2 nodes.

Login to the cloud: ibmcloud login --sso

Get access to a temporary access code:

Do not select a region, and do not ipdate the cli.

Access the Openshift cluster: oc login --server https://.....

Verify nodes and services

oc get nodes 
oc get svc,deploy,po --all-namespaces

Openshift try¶

Red Hat OpenShift trial. With this environment we cannot create new project, only use two predefined projects.

Having an image registry¶

We can use docker hub, quay.io or define a private registry:

• ibm cloud container registry provides a multi-tenant private image registry that you can use to store and share your container images with users in your IBM Cloud account
• Amazon Elastic Container Registry (ECR) we can share container software privately within your organization or publicly worldwide for anyone to discover and download. geo-replicated for high availability and faster downloads

To move one image from one registry to another use docker tag to change the image name:

docker tag <source_image>:<tag> <region>.icr.io/<my_namespace>/<new_image_repo>:<new_tag>
