Release Notes and Known Issues

Red Hat Container Development Kit 3.11 is based on Minishift, a command line tool to provision OpenShift locally for application developers. It supports all native hypervisors and some additional ones:

When you attempt to build a FUSE template, it fails because the template specifies that images are to be pulled from registry.redhat.io, and credentials for the registry are not included in the myproject OpenShift namespace used by Container Development Kit. This works as expected in the openshift namespace.

When running minishift start and the xPaaS addon is applied before the API server becomes responsive, the process fails with the following error message:

Error during post cluster up configuration: Error executing command 'oc apply -f v#{OPENSHIFT_VERSION}/xpaas-streams -n openshift'.

To work around this issue, re-apply the addon:

$ minishift addons apply xpaas

Due to a regression in version 0.4.4 of the xhyve driver plug-in, CDK fails to start.

Workaround: Uninstall the existing version of the xhyve driver plug-in and install version 0.3.3:

$ brew uninstall docker-machine-driver-xhyve
$ brew install https://raw.githubusercontent.com/igas/homebrew-core/33639d982eb5d0470562c3311e33040054eb87ee/Formula/docker-machine-driver-xhyve.rb

minishift console does not work on older versions of the Safari web browser such as version 10.1.2 (12603.3.8). Attempting to access the web console results in the following error:

Error unable to load details about the server

Retry after updating Safari to the latest version or use the Firefox or Chrome web browsers for this. Safari version 11.0.3 (13604.5.6) has been tested and works with the OpenShift web console. You can use minishift console --url to get the web console URL.

The system tray icon (introduced as a Technology Preview feature in Container Development Kit 3.7) does not show profile status. There is no workaround available.

The experimental static IP feature is not possible with the Default Switch provided by Windows. The minishift virtual machine will receive an IP address, but network traffic will not be able to pass through it.

See Assign IP Address to Hyper-V for more information about how to assign a static IP address to the minishift VM on Windows.

Windows Command Prompt and PowerShell have problems with parsing JSON into the minishift openshift config set command. Special attention is required when using this command on Windows.

The workaround for Windows Command Prompt environments is to escape the quotes so that the JSON content is correctly parsed:

C:\Users\CDK> minishift.exe openshift config set --patch "{\"routingConfig\": {\"subdomain\": \"192.168.99.101.nip.io\"}}"

The workaround for Windows PowerShell environments is to use a variable to store the JSON content:

PS C:\Users\CDK> $json='{\"routingConfig\": {\"subdomain\": \"192.168.99.101.nip.io\"}}'
PS C:\Users\CDK> echo $json
{\"routingConfig\": {\"subdomain\": \"192.168.99.101.nip.io\"}}
PS C:\Users\CDK> minishift.exe openshift config set --patch $json
Patching OpenShift configuration /var/lib/origin/openshift.local.config/master/master-config.yaml with {"routingConfig": {"subdomain": "192.168.99.101.nip.io"}}

The reason for this failure is currently unknown.

Workaround: Configure the OpenShift cluster from inside of the provisioned VM using minishift ssh:

C:\Users\CDK> minishift.exe ssh
[docker@minishift ~]$ docker exec -t origin /usr/bin/openshift ex config patch /var/lib/origin/openshift.local.config/master/master-config.yaml --patch='<json-to-be-applied-to-the-cluster>'
