Get started with Carbon

Install Carbon

Carbon installation

Install Minikube

Install Minikube (https://kubernetes.io/docs/tasks/tools/install-minikube/) and make sure that Minikube is started: minikube start & minikube status

Install Docker

https://docs.docker.com/install/

Clone Carbon git repository

Clone Carbon git repository (https://github.com/StarOfService/carbon) and change the current working directory (CWD) to ./test folder

Files overview

At the CWD you may find 2 files:

  • Dockerfile - is a standard Dockerfile which will be used for building a Docker image. The one you're observing now contains only FROM scratch. It's because we don't have any real application which has to be built into the Docker image. When you're be working with a real application, you have to add this application into the Docker image. For more details please check an official Dockerfile reference (https://docs.docker.com/engine/reference/builder/)
  • carbon.yaml - is a package config which contains Carbon-specific parameters related to your package. More details can be found at Package config

Also, the CWD contains 2 folders:

  • k8s - in this folder you can find Kubernetes manifests. The path for manifests if configured by kubeManifests parameter at the package config.
  • hooks - here we put lifecycle hooks. If you want to learn more about this feature, please check Hooks and hooks parameter at the package config

Docker image template

Please open k8s/deployment.yaml file and find containers section at the Deployment resource specification. Pay attention to the line: image: '{{.Pkg.DockerName}}:{{.Pkg.DockerTag}}'. As you can see, it doesn't contain any real Docker image name, we use template variables instead. We'll return to this point a bit later, on an installation stage.

Carbon package building

We've checked the content of the working directory and now we're ready to build our first Carbon package. Type: carbon build -m. -m flag directs Carbon to use Minikube VM which we installed on the 2nd step. The output will be like this:

$ carbon build -m

You may notice that the significant part of the output is standard output for docker build, but on the second step, there's added a huge label. It's a Carbon package metadata which contains some parameters from the package config and base64-encoded Kubernetes manifest templates. Now you can see how Carbon extends Docker image in order to store Kubernetes manifests.

Docker image inspection

You can do all standard Docker operations with the Carbon package, for example, inspect. Due to the -m flag, the image was built at the Minikube VM. In order to configure our local Docker client to use Minikube docker daemon, Minikube provides a command minikube docker-env. Please type this command and follow the instructions for your OS. When the Docker client is configured, we can check the docker image details:

    }
]

As you can see, it's a standard Docker image, which just contains an additional label. Hence you can operate with this image as any other Docker image: pull, push, store on a Docker registry, use other third-party tools.

Carbon package inspection

Let's check the information for the Carbon package:

$ carbon inspect -m carbon-test:0.0.1
Name: carbon-test
Version: 0.0.1
Variables:
  NAME           DEFAULT      DESCRIPTION
  FullName       carbon-test
  Environment    local
  KubeNamespace  default
  Cluster        core         K8s cluster name

Here Carbon reads the package metadata from the docker label and exposes basic information about the package:

  • package name
  • package version
  • package variables and default values for those variables

Carbon package installation

Now let's install the package to a Kubernetes cluster:

$ carbon install -m carbon-test:0.0.1
INFO[2019-02-13T11:06:44+03:00] Starting Carbon install
INFO[2019-02-13T11:06:44+03:00] Getting Carbon package metadata

INFO[2019-02-13T11:06:54+03:00] Carbon package has been installed successfully

At the Docker image template section I showed a template for the image field. The content for those variables is taken from the provided arguments. In our case it's carbon-test:0.0.1. It works fine for Minikube, but for a real environment, you want to push your image to a remote registry like docker-hub. When you are installing such Carbon package, you provide the remote image identifier. This identifier is passed to the templates and thus Kubernetes uses the same docker image which is used for the installation.

Feel free to use kubectl in order to check just created resources.

Installed Carbon packages overview

Now we can check what Carbon packages are installed to the Kubernetes cluster:

$ carbon status -m
  NAMESPACE  NAME         VERSION  SOURCE
  default    carbon-test  0.0.1    docker.io/library/carbon-test:0.0.1

Installed Carbon package details

If we need detailed information for a specific package, we should provide its name as an argument to the carbon status command:

$ carbon status -m carbon-test
Namespace: default
Name: carbon-test
Version: 0.0.1
Source: docker.io/library/carbon-test:0.0.1
Variables:
  NAME           VALUE
  Cluster        core
  Environment    local
  FullName       carbon-test
  KubeNamespace  default

We didn't override variables during the installation, that's why here we can see the default values. In fact, the current command shows real values which were used for the package installation.

carbon status has an additional -f/--full flag, which allows seeing the maximum available information about the package, including the eventual Kubernetes manifests:

$ carbon status -m carbon-test -f
Namespace: default
Name: carbon-test
Version: 0.0.1
Source: docker.io/library/carbon-test:0.0.1
Variables:
  NAME           VALUE
  Cluster        core
  Environment    local
  FullName       carbon-test
  KubeNamespace  default

Installed Carbon package uninstallation

Finally, let's clean up the environment from this testing package:

$ carbon uninstall -m carbon-test

Summary

As we just showed, Carbon allows operating (build, distribute and install) with your application and Kubernetes manifest as a single package. Now you are able to build a Carbon package, assign version, test a specific version and be sure that when you will be installing the package to your production environment, it will be absolutely the same package (with the same application code and kubernetes manifests) which was tested before.

If you want to learn more details about its features and how to build a Carbon package, please return to the documentation index and check pages dedicated to different aspects of the current tool.
