add an environnement variable named MAX_HOURS with the value that correspond to number of hours allowed after startup, like 8 for 8 hours).Replace the content of index.js file with the following: Name it mc_shutdown and use a Node.js 14.x or more runtime. Go into Lambda, and click on Create function to build a new one. This time we want to stop the instance after 8h. It's also necessary to publish an MX entry in order to declare SES as the email receiver for a specific domain or subdomain (more info here). You must add the domain to the Verified identities to make this work. If SES is receiving an email on this particular identity: Take note that the Email Receiving feature is only available today in 3 regions: us-east-1, us-west-2 and eu-west-1 (source here). In Simple Email Service, it's time to create a new Rule Set in the Email Receiving section:Ĭlick on Create rule inside default-rule-set. the role permissions must include the right to start our EC2 instance like this:.

add an environnement variable named INSTANCE_ID with the value that correspond to the Instance Id of your Minecraft server (something like i-031fdf9c3bafd7a34).Basically you must run this kind of command:Įnter fullscreen mode Exit fullscreen mode Then you must connect your instance via SSH, I recommend this guide if you need help.

In my case I am using an existing key pair but if you create a new key don't forget to download on your laptop the private key file. It's mandatory and allow then to connect remotely to your EC2 instance. Then to start the instance you must select or create a key pair. I add SSH port and the Minecraft port (25565) like you see on the following screen: Keep the default settings, and the default size for the disk (8 GB) as it's enough.įor the tag screen I generally provide a Name (it's then displayed on EC2 instance list) and a costcenter (I use it for cost management later).įor the Security Group, it the equivalent of a firewall on EC2 and you must configure which port will be accessible from internet on your server. You will able to change it after the creation.Ĭlick on Next: Configure Instance Details to continue the configuration. I recommend you the t2.small for Minecraft. From the EC2 dashboard, click on Launch Instance and choose the Amazon Linux 2 AMI with the x86 option. This is the initial part, you must create a new EC2 instance.

after 8h the instance is shutdown by the lambda function (I estimate that my son must not play on Minecraft more than 8h straight 😅).

send an e-mail to a specific and secret e-mail address, this will start the instance.

one Lambda function to start the serverĪnd that's it.

use SES (Simple Email Service) to receive e-mail, and trigger a Lambda function.

The global idea is to start the server only when my son is using it, but he doesn't have access to my AWS Console so I need to find a sweet solution!

Not a lot but I was thinking that there is room for improvement! The main part of the cost is the EC2 compute cost (~17 US$) and I know that it's not used 100% of the time. It's built on a EC2 t2.small with a 8 GB disk so I have a monthly cost of about 18 US$. The first month operating the server, I noticed that my son is using it a couple of hours each day, and then the server was idle. In this case I will focus on the Minecraft Java Edition, because the server version is running well on Linux server, and my son is running a laptop on Debian. Minecraft is a popular sandbox video-game. Simple Email Service (Email Sending and Receiving Service).There is always one service you don't know ! In this particular example I will use the following services: I want to rely only on AWS services as I want to increase my knowledge on this big cloud offering.

This article will explain you how to optimize the cost 😜, based on the usage!

After checking some available services (yeah not so expensive finally), I have chosen to build a server on a EC2 instance. During the first weeks of the COVID-19 pandemic, back in april 2020 my son ask me to build a Minecraft server in order to play on the same world with his school friend.
