Setup Tools

Please follow these steps to prepare for the Kubernetes Extensions lab:

  1. Install Operator SDK

  2. Configure Kubectl

1. Install Operator SDK

The Cloud Shell comes with several tools/libraries. For the lab, we will use the operator-sdk cli, which depends on Go to be installed. To check if both tools are installed in your shell, runn the following commands.

go version
operator-sdk version

If you see a command not found error, you will need to install both. For detailed installation instructions go here.

The version of the operator SDK used in the lab is 0.18.2. If the version shown from the above command is not 0.18.2, we need to install it.

curl -LO https://github.com/operator-framework/operator-sdk/releases/download/v0.18.2/operator-sdk-v0.18.2-x86_64-linux-gnu
chmod +x operator-sdk-v0.18.2-x86_64-linux-gnu
mkdir $HOME/operatorsdk0182
cp operator-sdk-v0.18.2-x86_64-linux-gnu $HOME/operatorsdk0182/operator-sdk
rm operator-sdk-v0.18.2-x86_64-linux-gnu
echo 'export PATH=$HOME/operatorsdk0182:$PATH' > .bash_profile
source .bash_profile

Check again,

operator-sdk version

2. Configure Kubectl

If you have not setup your kubectl to access your cluster, you can do so in the terminal environment

  1. Login to IBM Cloud using ibmcloud login. If asked, choose Advowork as your target account.

  2. Run the ibmcloud ks clusters command to verify the terminal and setup for access to the cluster

  3. Configure the kubectl cli available within the terminal for access to your cluster. If you previously stored your cluster name to an environment variable, use that (ie. $CLUSTER_NAME), otherwise copy and paste your cluster name from the previous commands output to the $CLUSTER_NAME portion below.

  4. Verify access to the Kubernetes API by getting the namespaces.

  5. You should see output similar to the following, if so, then your're ready to continue.
