Building and Installing the Crossplane DigitalOcean Provider

provider-digitalocean is composed of a golang project and can be built directly with standard golang tools. We currently support two different platforms for building:

  • Linux: most modern distros should work although most testing has been done on Ubuntu
  • Mac: macOS 10.6+ is supported

Build Requirements

An Intel-based machine (recommend 2+ cores, 2+ GB of memory and 128GB of SSD). Inside your build environment (Docker for Mac or a VM), 6+ GB memory is also recommended.

The following tools are need on the host:

  • curl
  • docker (1.12+) or Docker for Mac (17+)
  • git
  • make
  • golang
  • rsync (if you're using the build container on mac)
  • helm (v2.8.2+)
  • kubebuilder (v1.0.4+)

Build

You can build the Crossplane DigitalOcean Provider for the host platform by simply running the command below. Building in parallel with the -j option is recommended.

make -j4

The first time make is run, the build submodule will be synced and updated. After initial setup, it can be updated by running make submodules.

Run make help for more options.

Building inside the cross container

Official Crossplane builds are done inside a build container. This ensures that we get a consistent build, test and release environment. To run the build inside the cross container run:

build/run make -j4

The first run of build/run will build the container itself and could take a few minutes to complete, but subsequent builds should go much faster.

Install Crossplane in Your Cluster

Once your Kind Cluster is up and running, you'll need to install Crossplane.

We recommend using Helm to install Crossplane. You can find the official documentation here. These are the commands:

kubectl create namespace crossplane-system

helm repo add crossplane-stable https://charts.crossplane.io/stable
helm repo update

helm install crossplane --namespace crossplane-system crossplane-stable/crossplane

Install the DigitalOcean Crossplane Provider

  1. Find the provider installation file at examples/provider/install.yaml
  2. Run the installation:
kubectl apply -f https://raw.githubusercontent.com/crossplane-contrib/provider-digitalocean/main/examples/provider/install.yaml

Configure the DigitalOcean Crossplane Provider

  1. Find the provider config file at examples/provider/config.yaml
  2. Create a DigitalOcean personal access token
  3. Encode that token using base64, and in the config.yaml file, replace BASE64ENCODED_PROVIDER_CREDS with your encoded token
  4. Create a new Secret and ProviderConfig with
kubectl apply -f config.yaml
  1. Check that the Provider has been created by running
kubectl get ProviderConfig

You should see output similar to this:

NAME      AGE
example   34s

Provision DigitalOcean Resources

Once you have Crossplane installed in your cluster, and you've created created the DigitalOcean ProviderConfig resource, you can start spinning up DigitalOcean resources like Droplets, Managed Databases, and other DOKS clusters.

Go to the examples directory in this repo, find the DigitalOcean product you'd like to spin up, make any needed changes to the yaml file, and then create the resource.

For example, if you'd like to spin up a DigitalOcean Droplet, run the command

kubectl apply -f examples/compute

and check your DigitalOcean account to see if the Droplet has been created.
