ammbra/crafty-goblin

Contains 2 sample projects configured with DevSpace and Skaffold.

DevSpace vs Skaffold demo code

This repository contains the application code and setup used to inspect DevSpace vs Skaffold capabilities for iterative development.

Working with DevSpace

Project task-buddy contains the application on which DevSpace was demonstrated. Script setup.sh is based on this example: https://github.com/devspace-sh/devspace/tree/main/examples/spring-boot-mysql

Generate the k8s manifests

The project contains the spring dekorate.io dependency:

       <dependency>
            <groupId>io.dekorate</groupId>
            <artifactId>kubernetes-spring-starter</artifactId>
            <version>3.7.0</version>
        </dependency>

and the following configuration in aplication.properties:

dekorate.docker.registry=ghcr.io
dekorate.docker.group=ammbra
dekorate.docker.name=task-buddy
dekorate.docker.version=1.0
dekorate.docker.auto-push-enabled=false # disable image push
dekorate.docker.auto-build-enabled=false # disable image build
dekorate.output-path=../../k8s  # overwrite default path where the kubernetes manifests are generated

You can also generate Kubernetes manifests inside k8s folder (or any other folder of your liking) by running:

`mvn verify -Ddekorate.build=true --Ddekorate.output-path=../../k8s".

By default Dekorate generates the kubernetes manifests under target/classes, so -Ddekorate.output-path instructs Dekorate to create them in a directory relative to that path.

Start the dev mode

Run the following command to build a container image for your local development:

devspace build -t 1.0.0 --var=TARGET=build or its equivalent with devspace build-dev

Then just execute in a terminal devspace dev.

Next, you can execute devspace ui to see the commands that you can run in this project.

Deploy and rollback an application

You can build a production image by running:

devspace build-prod

Deploy the application using:

devspace deploy

In case of errors, run devspace run-pipeline rollback.

Working with Skaffold

Project task-pal contains the application on which Skaffold was demonstrated.

Generate the k8s manifests

The project contains the spring dekorate.io dependency:

       <dependency>
            <groupId>io.dekorate</groupId>
            <artifactId>kubernetes-spring-starter</artifactId>
            <version>3.7.0</version>
        </dependency>

and the following configuration in aplication.properties:

dekorate.docker.registry=ghcr.io
dekorate.docker.group=ammbra
dekorate.docker.name=task-pal
dekorate.docker.version=1.0
dekorate.docker.auto-push-enabled=false # disable image push
dekorate.docker.auto-build-enabled=false # disable image build
dekorate.output-path=../../k8s  # overwrite default path where the kubernetes manifests are generated

You can also generate Kubernetes manifests inside k8s folder (or any other folder of your liking) by running:

`mvn verify -Ddekorate.build=true --Ddekorate.output-path=../../k8s".

By default Dekorate generates the kubernetes manifests under target/classes, so -Ddekorate.output-path instructs Dekorate to create them in a directory relative to that path.

Start the dev mode

Run the following command to start development mode:

skaffold dev --default-repo=localhost:5000 -p dev --port-forward.

Deploy an application

You can build a production image by running:

skaffold deploy -p prod -t 1.0

Deploy the application using:

In case of errors, run skaffold debug and attach a remote debugger to the application.
