1. Installation and Prerequisites
5 minutes
BodyThe prerequisites for running CDK on Red Hat Enterprise Linux are:
- A Red Hat Developer Program username and password are required to enable the Red Hat Enterprise Linux VM included with the CDK to download and build container images from Red Hat. Please make sure to accept the terms and conditions.
- A virtualization platform, either Linux KVM or VirtualBox. For KVM you should have
libvirt
permissions to allow you to start and stop a VM using your normal, non-root user ID. - 25 GB of free disk space.
All of the commands in this section should be run as the root user.
For more information, see the CDK Gettting Started Guide.
1. Enable the Red Hat Developer Tools software repository
First, you need to enable the Red Hat Developer Tools and Red Hat Software Collections (RHSCL) software repositories using
subscription-manager
:$ su - # subscription-manager repos --enable rhel-7-server-devtools-rpms # subscription-manager repos --enable rhel-server-rhscl-7-rpms
Note: Change-server-
to-workstation-
if you aren't using the server variant of Red Hat Enterprise Linux. For developers, we recommend using Red Hat Enterprise Linux Server for access to the widest range of development tools. For developers, a no-cost subscription is available from developers.redhat.com.Next, add the Red Hat Developer Tools key to your system. This allows
yum
to verify the integrity of the download packages:# cd /etc/pki/rpm-gpg # wget -O RPM-GPG-KEY-redhat-devel https://www.redhat.com/security/data/a5787476.txt # rpm --import RPM-GPG-KEY-redhat-devel
2. Install the CDK
To install the CDK, run the following command as the root user:
# yum install cdk-minishift docker-machine-kvm
Note: if you intend to use VirtualBox instead of Linux KVM, you can skip the installation of
docker-machine-kvm
. -
2. Setup the CDK
5 minutes
BodyThe CDK is a single executable,
minishift
, which includes a number of bundled components. You use theminishift
command to start, stop, and configure the Red Hat Enterprise Linux 7 VM and the Red Hat OpenShift Container Platform single-node cluster running inside of the VM.The
oc
command line tool which is used for interacting with OpenShift clusters is downloaded when you runminishift setup-cdk
. Theoc
command must match the version of OpenShift running inside of the VM. Theminishift oc-env
command provides the statements to add the correct version ofoc
to yourPATH
. The output ofminishift oc-env
is intended to be evaluated by your shell after runningminishift start
.The setup steps are:
- Run
minishift setup-cdk
to set up your CDK environment in~/.minishift
- Add your Red Hat Developer Program username to your environment
All of the commands in this section should be run under your normal, non-root user ID.1. Run
minishift setup-cdk
Run
minishift setup-cdk
to setup the components needed to run CDK on your system. By default,minishift setup-cdk
places CDK content in~/.minishift
.$ minishift setup-cdk Setting up CDK 3 on host using '/home/user/.minishift' as Minishift's home directory Copying minishift-rhel7.iso to '/home/user/.minishift/cache/iso/minishift-rhel7.iso' Copying oc to '/home/user/.minishift/cache/oc/v3.11.43/linux/oc' Creating configuration file '/home/user/.minishift/config/config.json' Creating marker file '/home/user/.minishift/cdk' Default add-ons anyuid, admin-user, xpaas, registry-route, che, htpasswd-identity-provider, eap-cd installed Default add-ons anyuid, admin-user, xpaas enabled CDK 3 setup complete.
Note: If you would like to use a different directory see Environment Variables in the CDK Getting Started Guide.
If you delete
~/.minishift
, you will need to run this step again.2. Add your Red Hat Developer Program username to your environment
The VM needs to register with Red Hat to download and build container images. Add your Red Hat Developer Program username to your environment to avoid the need to enter it each time you start
minishift
. Your password is stored in the system keystore, so after you log in once, the CDK simply retrieves the password from the keystore.The following command sets the username in the environment of the running shell. When a new command shell is started you will need to enter this command again.
$ export MINISHIFT_USERNAME='<RED_HAT_USERNAME>'
Optional: Permanently storing the username
The following command adds your username to your profile so it will be set on future logins.
$ echo export MINISHIFT_USERNAME=$MINISHIFT_USERNAME >> ~/.bashrc

10 minutes
BodyStart
minishift
You are now ready to start the CDK. The
minishift start
command starts a Red Hat Enterprise Linux VM with an OpenShift cluster running inside.Note: By this point you should have your hypervisor configured as per the hypervisor prerequisites in step 1:
- If you are using KVM, make sure you've installed the
docker-machine-kvm
driver. - If you are using VirtualBox, configure
minishift
to use VirtualBox withminishift config set vm-driver virtualbox
You should have also completed the CDK setup from step 2.
Run
minishift start
Start the VM with
minishift start
:$ minishift start -- Starting profile 'minishift' ... -- Minishift VM will be configured with ... Memory: 4 GB vCPUs : 2 Disk size: 20 GB -- Starting Minishift VM .......................... OK -- Registering machine using subscription-manager Registration in progress ..................... OK [42s] ... Extracting Image pull complete OpenShift server started. The server is accessible via web console at: https://192.168.42.60:8443 You are logged in as: User: developer Password: To login as administrator: oc login -u system:admin ...
After
minishift start
completes, make a note of:- The URL for the OpenShift cluster. Note: the IP address may change when you restart the CDK.
- The developer username.
- The admin username and default password.
To check that everything is working and view the OpenShift console use the command:
$ minishift console
This launches the URL listed above (for example:
https://192.168.42.60:8443
) with your default browser. You will likely get a security warning from the browser about the certificate being from an unknown certificate authority. This is expected. You need to accept the certificate to proceed.To open the console in another browser, you can get the URL of the console with the following command:
$ minishift console --url
Login to OpenShift using
developer
as the username. Enter any text for the developer password.Add the directory containing
oc
to yourPATH
After the
minishift
VM has been started, you need to addoc
to yourPATH
. Theoc
command must match the version of the OpenShift cluster that is running inside of the Red Hat VM. The following command sets the correct version dynamically by runningminishift oc-env
and parsing the output.$ eval $(minishift oc-env)
Stopping
minishift
and the CDK life-cycleYou can stop the
minishift
VM with the command:$ minishift stop
You can restart it again with:
$ minishift start
If necessary, you can delete the VM to start over with a clean VM using:
$ minishift delete
You won't need to run
minishift setup-cdk
again unless you delete the contents of~/.minishift
. You can learn more in the CDK life-cycle section of the CDK Getting Started Guide.Build your first app

Prerequisites for running the CDK on macOS
The prerequisites for running the CDK on macOS are:
-
A Red Hat Developer Program username and password are required to download CDK and to enable the Red Hat Enterprise Linux VM included with the CDK to download container images from Red Hat. Please make sure to accept the terms and conditions.
-
A virtualization platform (hypervisor): Xhyve or VirtualBox.
-
For Xhyve you need to install the
docker-machine-xhyve
driver.
-
-
25 GB of free disk space.
Hypervisor
CDK includes a prebuilt Red Hat Enterprise Linux virtual machine with OpenShift and other container tools pre-installed. To run the VM a hypervisor is required.
Xhyve
Xhyve is the default hypervisor on macOS. You will need to install the
docker-machine-xhyve
driver. See Set up the xhyve driver in the CDK Getting Started Guide for installation details.VirtualBox
CDK supports VirtualBox 5.1.14 and later on all platforms. No additional downloads are required to use VirtualBox.
Since VirtualBox is not the default hypervisor, you either need to pass the command line option
--vm-driver virtualbox
to theminishift start
command or make the setting persistent with the following command:$ minishift config set vm-driver virtualbox
Verify the configuration setting with:
$ minishift config get vm-driver
Minishift persistent configuration is stored in the
~/.minishift
directory. If you delete~/.minishift
you will need to run the commands to configure any persistent settings again. See Persistent Configuration in the CDK Getting Started Guide for more information. -
2. Setup the CDK

BodyThe CDK download is a single executable named
minishift
that includes a number of bundled components. Use theminishift
command to start, stop, and configure the Red Hat Enterprise Linux 7 VM and the Red Hat OpenShift Container Platform single-node cluster running inside of the VM. To runminishift
commands, you need to move theminishift
download to a directory that is in your command search path.The
oc
command line tool which is used for interacting with OpenShift clusters is downloaded when you runminishift setup-cdk
. Theoc
command must match the version of OpenShift running inside of the VM. Theminishift oc-env
command provides the statements to add the correct version of oc to your PATH. The output ofminishift oc-env
is intended to be evaluated by your shell after runningminishift start
.The setup steps are:
- Copy
minishift
into a directory that is in your path - Run
minishift setup-cdk
. to set up your CDK environment in~/.minishift
- Add your Red Hat Developer Program username to your environment (starting with CDK 3.7, your password is automatically added to the system keystore the first time you log in)
Setup
Adding
minishift
to your pathThe
minishift
file you downloaded in the first step is an executable. To runminishift
commands, copy it to a directory that is in already in your path, or create a directory and add it to thePATH
environment variable.Note: In the shell,~/
is an expression that automatically expands to your home directory, typically/Users/username
. This guide uses that convention to refer to your home directory.Copy the downloaded
minishift
file into~/bin
which is conventionally used as the location for executables in your home directory:$ mkdir -p ~/bin $ cp ~/Downloads/minishift ~/bin $ chmod +x ~/bin/minishift
You can check if
~/bin
is in your path with one of the following commands:$ echo $PATH $ which minishift
If you need to add
~/bin
to your PATH, run the following commands to add it to your current and future login sessions:$ echo 'export PATH=$PATH:$HOME/bin' >> ~/.bashrc $ export PATH=$PATH:$HOME/bin
Run
minishift setup-cdk
Run
minishift setup-cdk
to setup the components needed to run CDK on your system. By default,minishift setup-cdk

1. Download and Prerequisites
5 minutes
BodyDownload Red Hat Container Development Kit (CDK). Please see Prerequisites for running the CDK on Windows and Notes for Windows Users below.- CDK 3.7.0 for Windows (463 MB)
Prerequisites for running the CDK on Windows
The prerequisites for running the CDK are:
- A Red Hat Developer Program username and password are required to download the CDK and to enable the Red Hat Enterprise Linux VM included with the CDK to download container images from Red Hat. Please make sure to accept the terms and conditions.
- A virtualization platform (hypervisor): Hyper-V or VirtualBox.
- 25 GB of free disk space.
Hypervisor
The CDK includes a prebuilt Red Hat Enterprise Linux virtual machine with OpenShift and other container tools pre-installed. To run the VM a hypervisor is required. Please make sure that the virtualization hardware extensions (VT-x or AMD-V) are enabled in your system’s BIOS.
Hyper-V
Hyper-V is the default virtualization platform for CDK on Windows, but must be enabled as a Windows optional feature. Hyper-V isn’t available on some versions of Windows. (VirtualBox is supported as an alternative on all versions of Windows.) Once you install Hyper-V, you must add your user account to the Hyper-V Administrators group.
Next, create an external virtual network switch and attach it to your physical network card (wired or wireless, whichever is connected) to enable internet access for downloading container images. Either of the following commands will work. The first sets the default value of
hyperv-virtual-switch
, while the second uses the value for the current command only:C:\> minishift config set hyperv-virtual-switch "External (Wireless)"
C:\> minishift start --hyperv-virtual-switch "External (Wireless)"
Be aware that the name of the virtual switch is case sensitive. For additional information on Hypervisor configuration see Set up hypervisor on Windows in the CDK Getting Started Guide or Setting up the Hyper-V Driver in the OKD documentation.
VirtualBox
CDK supports VirtualBox 5.1.14 and later on all platforms. No additional downloads are required to use VirtualBox.
Since VirtualBox is not the default hypervisor, you either need to pass the command line option
--vm-driver virtualbox
to theminishift start
command or make the setting persistent with the following command:C:\> minishift config set vm-driver virtualbox
You can verify the configuration setting with:
C:\> minishift config get vm-driver
Minishift persistent configuration is stored in the
.minishift
directory, which is located in your home directory. If you delete%USERPROFILE%\.minishift
, you need to run the commands to configure any persistent settings again. See Persistent Configuration in the CDK Getting Started Guide for more information.Notes for Windows users
Windows shells and environment variables
You can run the CDK using the Windows command prompt or PowerShell. Working with the CDK and
minishift
requires setting a number of environment variables. You may encounter CDK information that shows the syntax for the bash shell, as that syntax can be used with Linux or macOS. The syntax for setting environment variables is different for the Windows command prompt and PowerShell. There are also some differences in the quoting that is required for arguments that include spaces or special characters. If you run into problems, check that you’ve correctly set any required environment variables, verify that any variables contain the expected values withset
(for the command prompt) orGet-ChildItem ENV:
(for PowerShell).When setting environment variables it is important to understand the scope of the change. Using
set VARIABLE=value
in the command prompt or$env:VARIABLE = value
in PowerShell only affects the running shell and any processes started from that shell. When a new shell is started or the system is rebooted, the environment variable is no longer set.Environment variable settings can be made persistent by storing them in the user’s profile as part of the registry. This can be done by using the Windows Control Panel. However, this does not affect any running processes. You must start a new command shell for those changes to become part of your runtime environment.
Adding a directory to your PATH
CDK includes two command line tools,
minishift.exe
andoc.exe
, that need to be located in a directory that is listed in yourPATH
environment variable. You can temporarily add a directory to the command search path by setting thePATH
environment variable in the current shell. The change only affects the running shell and any processes started from that shell. If you start a new shell, you need to change thePATH
environment variable again.To permanently change your
PATH
, use the Windows Control Panel. Environment variable settings are found under Control Panel -> System -> Advanced System Settings -> Environment Variables. You can also get there directly by searching for Environment Variables in the Start Menu and selecting Edit Environment Variables for Your Account. These changes do not affect any currently running shells. Close any open shells and start a new shell.Only the directory containing
minishift.exe
should be permanently added to thePATH
. The directory containingoc.exe
can change and should be added dynamically to the running shell withminishift oc-env
.Note: Only make changes to User Environment Variables. There is aPATH
environment variable under both User Environment Variables and System Environment Variables. The user’sPATH
is used for shells running under your regular user account.User's home directory
The CDK stores state and configuration in the
.minishift
sub-directory of the user’s home directory. On Windows, the path is%USERPROFILE%\.minishift
, which is typicallyC:\user\username\.minishift
. You may encounter CDK information that uses the Bash shorthand~/
to refer to the user’s home directory, for example~/.minishift
. The Windows equivalent for~/
is%USERPROFILE%\
. Note: Using PowerShell the environment variable syntax is$env:USERPROFILE
. -
2. Setup the CDK
5 minutes
BodyThe CDK download is a single executable that includes a number of bundled components. Use
minishift.exe
to start, stop, and configure the Red Hat Enterprise Linux 7 VM and the Red Hat OpenShift Container Platform single-node cluster running inside of the VM. To runminishift
commands, you need to move theminishift.exe
file to a directory that is in your command search path.The
oc
command line tool used for interacting with OpenShift clusters is downloaded when you runminishift setup-cdk
. Theoc
command must match the version of OpenShift running inside of the VM. The output ofminishift oc-env
command provides the statements to add the correct version ofoc
to yourPATH
.The setup steps are:
- Add
minishift.exe
to your path - Run
minishift setup-cdk
to set up your CDK environment - Add your Red Hat Developer Program username to your environment
Setup
Add
minishift.exe
to your pathThe
minishift.exe
file you downloaded in the first step is an executable. To runminishift
commands, copy it to a directory that is in already in yourPATH
, or create a directory and add it to thePATH
environment variable. The directory must be on your system (C:\
) drive.For the Windows command prompt:
C:\> mkdir %USERPROFILE%\bin C:\> copy %USERPROFILE%\Downloads\minishift.exe %USERPROFILE%\bin\minishift.exe
For PowerShell:
PS C:\> mkdir $env:USERPROFILE\bin PS C:\> copy $env:USERPROFILE\Downloads\minishift.exe $env:USERPROFILE\bin\minishift.exe
if the directory isn’t already in your
PATH
, use the Windows Control Panel to update yourPATH
environment variable. Note: You need to start a new shell window for the change to take effect. See Windows Shells and Environment Variables above for more information.Run
minishift setup-cdk
to set up your CDK environmentRun
minishift setup-cdk
to setup the components needed to run CDK on your system. By default,minishift setup-cdk
places CDK content in%USERPROFILE%\.minishift

Note: To use a different directory, see Environment Variables in the CDK Getting Started Guide.
If you delete
%USERPROFILE%\.minishift
, you will need to run this step again.Add your Red Hat Developer Program username to your environment
The VM needs to register with Red Hat to download and build container images. You can add your Red Hat Developer Program username to your environment to avoid the need to enter it each time you start
minishift
. Your password is stored in the system keystore, so after you log in once, the CDK uses the username from the environment variable and retrieves the password from the keystore.The following command sets the username in the environment of the running shell. When a new command shell is started, you will need to enter this command again.
For the Windows command prompt
C:\> set MINISHIFT_USERNAME=<RED_HAT_USERNAME>
For PowerShell
PS> $env:MINISHIFT_USERNAME='<RED_HAT_USERNAME>'
Optional: Permanently storing the credentials
You can permanently store environment variables in the registry using the Windows Control Panel. After that, when you start a new command shell the environment variables are automatically set. You will need to start a new command shell for the change to take effect.
