Use this procedure to install MicroK8s and prepare it for DCT deployment on Ubuntu, CentOS, or Red Hat. Review the MicroK8s requirements and prerequisites before you begin.

Ubuntu

  1. To install MicroK8s, open a terminal window and execute the following command:

    sudo snap install microk8s --classic --channel=1.25

    1. If snap is not installed on your system, follow the instructions here to install it.

  2. MicroK8s creates a user group to enable seamless command execution. Add your user to this group and set the correct permissions for the .kube caching directory with:

    sudo usermod -a -G microk8s $USER
sudo chown -f -R $USER ~/.kube

    1. Re-login or restart your session to apply the group changes:

      su - $USER

  3. Check the MicroK8s status to see if its correctly installed by using:

    microk8s status --wait-ready

  4. Enable essential add-ons for DCT deployment:

    microk8s enable hostpath-storage
microk8s enable helm
microk8s enable dns
microk8s enable ingress

  5. Create an alias for kubectl and helm with:

    echo "alias kubectl='microk8s kubectl'" >> ~/.bash_aliases
echo "alias helm='microk8s helm'" >> ~/.bash_aliases
source ~/.bash_aliases

CentOS and Red Hat

For CentOS and Red Hat, the installation process diverges primarily due to the absence of snap by default.

  1. Enable the EPEL repository and install snapd.

    sudo yum install epel-release
sudo yum install snapd

    1. Then, start and enable snapd:

      sudo systemctl enable --now snapd.socket

    2. For CentOS, you may also need to enable classic snap support by creating a symbolic link:

      sudo ln -s /var/lib/snapd/snap /snap

  2. With snapd enabled, install MicroK8s with snap:

    sudo snap install microk8s --classic --channel=1.25

  3. Follow the same steps for Ubuntu (above) and add your user to the MicroK8s group, and adjust permissions for the .kube directory.

  4. Verify the MicroK8s installation success and enable the necessary add-ons, as outlined above.

  5. Create and source the alias for kubectl and helm, as described above.
