Prerequisites

Google Cloud Platform

This tutorial uses Anthos which is on the Google Cloud Platform (GCP). If you don’t have an account, you can sign up for $300 in free credits.

Estimated cost to run this tutorial is $9 per day.

After signing up, create a GCP project and attach to a billing account.

GitLab

This tutorial uses GitLab for code repository and for continuous integration & continuous delivery.

Sign up to create a GitLab account if you don’t already have one.

To grant your laptop access to make changes as this account, generate and add SSH keys to your account.

Generate SSH keys:

ssh-keygen

It is recommended to add a passphrase when generating new ssh keys, but for this demo you can proceed without setting one.

Copy content of id_rsa.pub, paste in the key textbox and add key.

Create a new public group and give it a name of choice (e.g anthos-demo). When creating a group, gitlab assigns you a URI. Take note of the URI. All repositories/projects created during this tutorial will be under this group.

Install and Initialize the Google Cloud SDK

Follow the Google Cloud SDK documentation to install and configure the gcloud command line utility.

At the time this doc was created, some tools used in this tutorial are still in beta. To be able to utilize them, install gcloud beta

gcloud components install beta

Initialize gcloud config with the project id:

gcloud init

Then be sure to authorize gcloud to access the Cloud Platform with your Google user credentials:

gcloud auth login

Install Kubectl

The kubectl command line utility is used to interact with the Kubernetes API Server.

Download and install kubectl using gcloud:

gcloud components install kubectl

Verify installation:

kubectl version --client

Install nomos

The nomos command is an optional command-line tool used to interact with the Config sync operator.

Download nomos:

gcloud components install nomos

macOS and Linux clients should run this extra command to configure the binary to be executable.

chmod +x </path/to/nomos>

Move the command to a location your system searches for binaries, such as /usr/local/bin, or you can run the command by using its fully-qualified path.

Environment variables

The following environment variables are required for some of the commands in this guide

export PROJECT_ID="<project id you created earlier>"
export PROJECT_NUMBER="$(gcloud projects describe "${PROJECT_ID}" \
--format='value(projectNumber)')"
export USER="<user email you are using>"
export GROUP_NAME="<your gitlab group name>" # if your group name has space(s), replace with `-`
export GROUP_URI="<your gitlab group URI>"
export REGION="us-central1"
export ZONE="us-central1-c"
