Ymir requires AWS services that aren't available in all AWS regions. For that reason, only the following AWS regions are available at this time:
ap-northeast-1— Asia Pacific (Tokyo)
ap-northeast-2— Asia Pacific (Seoul)
ap-south-1— Asia Pacific (Mumbai)
ap-southeast-1— Asia Pacific (Singapore)
ap-southeast-2— Asia Pacific (Sydney)
ca-central-1— Canada (Central)
eu-central-1— EU (Frankfurt)
eu-north-1— EU (Stockholm)
eu-west-1— EU (Ireland)
eu-west-2— EU (London)
eu-west-3— EU (Paris)
sa-east-1— South America (São Paulo)
us-east-1— US East (N. Virginia)
us-east-2— US East (Ohio),
us-west-1— US West (N. California)
us-west-2— US West (Oregon)
Ymir has the following requirements:
While WordPress still supports older versions of PHP, Ymir is a platform for modern PHP. The composer requirement is only for installing the Ymir CLI tool. Your WordPress project doesn't need to use composer for Ymir to deploy it.
While not a strict requirement, it's highly recommended to have WP-CLI (opens new window) installed. The Ymir CLI tool has advanced functionality available if WP-CLI is present on the local machine.
The Ymir CLI needs PHP compiled with the zip extension. If Composer gives you an error about the extension missing, you'll need to reinstall PHP. If you're using a Mac, you can reinstall it using Homebrew (opens new window) using the procedure here (opens new window).
# Installing the Ymir CLI
Most of your interactions with Ymir will be through the Ymir CLI (opens new window) tool. You cannot deploy your WordPress projects without it.
# Globally (preferred)
The preferred way to install the Ymir CLI is globally. You can use the following command to do so:
$ composer global require ymirapp/cli
Global vendor binaries directory
For the global installation to work, you must have the global vendor binaries directory in your
$PATH environment variable. If you see the error
command not found: ymir, this is the cause. You can add the global vendor binaries directory to your
$PATH environment variable by following the procedure here (opens new window).
After the installation, you can use the Ymir CLI like this:
$ ymir <command>
# Inside your project
You can also install the Ymir CLI in the specific projects that use Ymir. To do so, you just need run the following composer commmand:
$ composer require ymirapp/cli
When installed inside a project, you can find the Ymir CLI in the vendor binaries directory. To run a Ymir CLI command, you then write your commands like this:
$ vendor/bin/ymir <command>
# Creating an account
Before you begin to use Ymir, you're going to need an account on the platform. If you're just working on someone else's team, you don't need to have a paid Ymir subscription. It's only required for creating projects and managing resources on your own teams.
Speaking of teams, whenever someone creates an account on Ymir, a Personal team also gets created. You cannot delete this team, but you can rename it. That's because teams are central to Ymir. All your projects and resources are tied to a team.
# Connecting a team to AWS
In order to create resources and deploy projects, a team must be connected to at least one AWS account. You can do this with the
provider:connect command or through the team management (opens new window) page. But before doing that, you'll need an AWS account to connect to.
# Creating an AWS account
If you don't already have an AWS account, you'll want to create one first. You can do this from the account creation page here (opens new window).
AWS costs not included
Your Ymir subscription doesn't include your AWS costs. So please ensure that you enter billing information when creating your AWS account.
# Adding an IAM user
Connecting to an AWS account requires that you have an IAM user with programmatic access. It is preferable to create one especially for Ymir. You can do this through the IAM console (opens new window) or with the AWS CLI.
Using the AWS dashboard, you want to navigate to the IAM console. There, you'll want to click on Users on the left sidebar and then click on Add user. This will bring up the user creation wizard.
The first step of the wizard has you choose a username. Once that's done, you want to check Programmatic access checkbox in access type section below. Once you click Next, you'll be on the permissions screen.
There, you'll want to give administrator access to the user that you're creating. You do that by switching to the Attach existing policies directly tab. And from the list of policies that gets displayed, you select the AdministratorAccess policy.
After attaching the policy, you can skip to the end and create the user. You'll then be on the success screen where the the new user's credentials will be displayed. The Access key ID and Secret access key are the credentials you have to give to Ymir when connecting your AWS account.
