Introduction

This page describes how to install Tanzu community Edition (aka: TCE) and play a nice Spring Boot Petclinic demo.

TL;DR

TCE is a standalone client designed around a pluggable architecture, able to create clusters (unmanaged - local or managed - AWS, Azure, vSphere) like the packages and/or repository about the components to be installed.

References:

TCE installation

All in one

Use the following bash script to perform the following operations:

  • Install the Tanzu binary client
  • Create an unmanaged kubernetes cluster
  • Deploy some cool packages such as the App-Toolkit package able to demo a GitOps scenario

Execute the ./scripts/install.sh where you will set the following variables:

  • REMOTE_HOME_DIR: home directory where files will be installed locally or within the remote VM
  • VM_IP: IP address of the VM where the cluster is running (e.g.: 127.0.0.1)
  • CLUSTER_NAME: TCE Kind cluster name
  • TCE_VERSION: Version of the Tanzu client to be installed. (e.g.: v0.12.0)
  • TKR_VERSION: kubernetes version which corresponds to the Tanzu Kind Node TCE image. (e.g.: v1.22.7-2)
  • REGISTRY_SERVER: Container image registry (e.g: docker.io, ghcr.io, ...)
  • REGISTRY_OWNER: Username of the account, github org used to access the Registry server
  • REGISTRY_USERNAME: Registry account username
  • REGISTRY_PASSWORD: Registry account password
REMOTE_HOME_DIR="$HOME" \
VM_IP="127.0.0.1" \
CLUSTER_NAME="toto" \
TCE_VERSION="v0.12.0" \
TKR_VERSION="v1.22.7-2" \
REGISTRY_SERVER="ghcr.io" \
REGISTRY_OWNER="<org>" \
REGISTRY_USERNAME="<github_user>" \
REGISTRY_PASSWORD="<github_token>" \
./scripts/install.sh

or for remote deployment

tar -czf - ./scripts/*.sh |  ssh -i ${SSH_KEY} ${USER}@${IP} -p ${PORT} "tar -xzf -"
ssh -i ${SSH_KEY} ${USER}@${IP} -p ${PORT} \
    REMOTE_HOME_DIR="/home/centos" \
    VM_IP=${IP} \
    CLUSTER_NAME="toto" \
    TCE_VERSION="v0.12.0" \
    TKR_VERSION="v1.22.7-2" \
    REGISTRY_SERVER="ghcr.io" \
    REGISTRY_OWNER="<org>" \
    REGISTRY_USERNAME="<github_user>" \
    REGISTRY_PASSWORD="<github_token>" \
    "bash ./scripts/install.sh"

To uninstall it, use the command

REMOTE_HOME_DIR="/home/snowdrop" \
CLUSTER_NAME="toto" \
./scripts/uninstall.sh

or

ssh -i ${SSH_KEY} ${USER}@${IP} -p ${PORT} \
    REMOTE_HOME_DIR="/home/snowdrop" \
    CLUSTER_NAME="toto" \
    "bash ./scripts/uninstall.sh"

If you need to use a private image registry (= harbor), then execute the following bash command top of a running TCE. It will install the harbor package, will populate a selfsigned CA certificate/key and update the containerd running within the control-plane. Follow the instructions within the terminal to figure out how to update the docker certificate folder, to log on and push images to the private registry:

REMOTE_HOME_DIR=<LOCAL_OR_REMOTE_HOME_DIR> VM_IP=<VM_IP> CLUSTER_NAME="toto" ./scripts/install_harbor.sh

Manual steps

Install TCE

Install the Tanzu client using either released version or a snapshot as described hereafter

mkdir tce && cd tce/
TCE_OS_VERSION="tce-linux-amd64-v0.12.0-dev.1"
wget https://storage.googleapis.com/tce-cli-plugins-staging/build-daily/2022-03-08/$TCE_OS_VERSION.tar.gz
./install.sh

# Add completion
mkdir $HOME/.tanzu
tanzu completion bash >  $HOME/.tanzu/completion.bash.inc
printf "\n# Tanzu shell completion\nsource '$HOME/.tanzu/completion.bash.inc'\n" >> $HOME/.bash_profile

Create a K8s cluster

Create the TCE unmanaged cluster (= Kind cluster)

tanzu uc delete toto
tanzu uc create toto -p 80:80 -p 443:443

Configure/install the needed packages

Install the needed packages

TCE_DIR=tce

tanzu package install secretgen-controller --package-name secretgen-controller.community.tanzu.vmware.com --version 0.7.1 -n tkg-system

IP="<IP_OF_THE_VM>"
REGISTRY_SERVER="<ghcr.io or docker.io or>"

REGISTRY_USERNAME="<docker account or github username>"
REGISTRY_PASSWORD="<docker password or github token>"
tanzu secret registry add registry-credentials --server ghcr.io --username $REGISTRY_USERNAME --password $REGISTRY_PASSWORD --export-to-all-namespaces`

Demo

We will now install a Spring Petclinic demo and check if the application os build/deployed and service exposed

  --git-repo https://github.com/halkyonio/$APP.git#
  --git-branch main \
  --type web \
  --label app.kubernetes.io/part-of=$APP \
  -n demo

Tail the log of the workload to follow the status about the build, ...
