The EKS Ephemeral Cluster Manager¶
This is a service for development and test environments. It is not an official AWS offering, use at your own risk.
Managing Amazon EKS clusters for development and test environments manually is boring. You have to wait until they're provisioned and then have to remember to tear them down again, in order to minimize costs. How about automating these steps?
Meet EKSphemeral, the simple manager for ephemeral EKS clusters, allowing you to launch EKS clusters that auto-tear down after some time, and you can also prolong their lifetime if you want to continue to use them.
If you like, you can have a look at a video walkthrough, before you try it out yourself.
You can either use the EKSphemeral UI:
Or the EKSphemeral CLI:
In order to use EKSphemeral you need to have
jq (install) and the
aws CLI (install) installed.
All other dependencies, such as the Fargate CLI will be installed automatically, if not present on the system.
Make sure to set the respective environment variables as shown here before you proceed. Most install issue come from not all environment variables set.
The following environment variables need to be set so that the install process knows where the dependencies are and which
S3 bucket to use for the control plane (
EKSPHEMERAL_SVC_BUCKET) and where to
put the cluster metadata (
EKSPHEMERAL_CLUSTERMETA_BUCKET), for example:
1 2 3
$ export EKSPHEMERAL_HOME=~/eksp $ export EKSPHEMERAL_SVC_BUCKET=eks-svc $ export EKSPHEMERAL_CLUSTERMETA_BUCKET=eks-cluster-meta
Optionally, in order to receive email notifications about cluster creation and
destruction, you need to set the
EKSPHEMERAL_EMAIL_FROM environment variable, for example:
$ export EKSPHEMERAL_EMAIL_FROMfirstname.lastname@example.org
In addition to setting the
EKSPHEMERAL_EMAIL_FROM environment variable, you MUST verify both the source email, that is, the address you provide in
EKSPHEMERAL_EMAIL_FROM as well as the target email address (in the
owner field of the cluster spec, see below for details) in the EU (Ireland)
We're now in the position to install EKSphemeral with a single command, here shown for an install below your home directory:
$ curl -sL http://get.eksphemeral.info/install.sh | sudo --preserve-env bash
This process can take several minutes. After this, EKSphemeral is installed in your AWS environment as well as the CLI is locally available. Learn more about what exactly is created and running as part of the install process by perusing the EKSphemeral architecture.
