How much of CSE you need to install varies on the user type and what part of CSE and Kubernetes you will interact with. Here’s a short table to help decide what to install.
|Kubernetes user||Install kubectl on laptop or workstation|
|Org admin managing K8s clusters||Install CSE and configure CSE client on laptop or VM|
|Cloud admin installing CSE in vCD||Install CSE on server host|
Naturally a cloud admin may install the CSE client to test cluster creation after CSE server setup. Similarly a tenant org administrator may install kubectl to check Kubernetes clusters or perform administrative tasks.
Install kubectl using directions from the Kubernetes web site.
Install CSE Software
Install Python 3.6 or greater. See Python installation instructions and downloads at https://www.python.org or consult the vcd-cli install procedure. Pip, Python’s package manager comes with Python.
Verify python and pip installation:
$ python3 --version Python 3.7.0 $ pip3 --version pip 18.0 from /usr/local/lib/python3.7/site-packages/pip (python 3.7)
Now install and verify CSE:
$ pip3 install container-service-extension ... $ cse version CSE, Container Service Extension for VMware vCloud Director, version 1.2.5
Alternatively, a specific version of CSE can be installed from GitHub as follows:
> pip3 install git+https://firstname.lastname@example.org
NOTE: pip3 install from git fails on virtual environments created by
python3 -m venv. See https://github.com/vmware/container-service-extension/issues/181 for details and workaround.
To discover available CSE source versions on GitHub see the following URL: https://github.com/vmware/container-service-extension/tags
Enable CSE Client
After initial installation you’ll see a response like the following
vcd cse commands, which means that the CSE client
is not enabled.
> vcd cse version Error: No such command "cse".
To enable edit
~/.vcd-cli/profiles.yaml to include this section:
extensions: - container_service_extension.client.cse
Save the file and try again.
vcd cse commands should now work.
