hello-world

Sample project for Tanzu Platform

install tanzu cli

Instructions at: https://github.com/vmware-tanzu/tanzu-cli/blob/main/docs/quickstart/install.md

On a Mac:

brew tap vmware-tanzu/tanzu
brew install tanzu-cli

install cli plugins

tanzu plugin install --group vmware-tanzu/app-developer:v1.0.0

log in to the platform

You need to have an environment available

Using your default org:

tanzu login

Using specific endpoint:

tanzu login --endpoint <provided endpoint>

Using specific endpoint with self-signed certs:

tanzu login --endpoint <provided endpoint> --endpoint-ca-certificate <path to cert>

For a staging environment:

tanzu login --staging --endpoint <provided endpoint>

select a project to use

tanzu project use

create a space

Use the provided spring-dev-space.yml to create a space

tanzu deploy --only spring-dev-space.yml

use the new space

tanzu space use spring-dev-space

initialize the app

tanzu app init

we need java 21 and 1 instance to start with

tanzu app config build non-secret-env set BP_JVM_VERSION=21
tanzu app config scale set instances=1

build the app

configure for local daemon builds

you need a registry that is accessible from the platform environment.

For DockerHub:

tanzu build config --build-engine daemon
tanzu build config --containerapp-registry docker.io/<docker-id>/{name}

The {name} part is a placeholder that will be resolved to match your app at build time, so leave that as is.

configure for platform builds

tanzu build config --build-engine platform

deploy the app

tanzu deploy

scale the app

tanzu app scale hello-world --instances=2

access the app

Use port-forward

tanzu app port-forward hello-world --port 8080

use curl to get some feedback

curl localhost:8080
